A BIOS password is a protection measure that can be used to stop someone powering up a computer system
or making changes in some of the computers most sensitive areas. Many big name computer manufacturers
such as Dell and HP lock the customers out of this area because they don’t want the customer changing
anything and potentially damaging the machine (which the manufacturer may have to warranty). However, when
someone like a computer technician or hardware enthusiast needs to make some hardware changes to the
computer, they will need to access the BIOS. Here are some methods to be a bios password cracker,
removing a BIOS password.
NOTE: Do not try to guess the password on a passworded Hard Drive. 3 wrong guesses will often result in the
information on the hard drive being lost forever.
How to Bypass or Remove a BIOS Password by Removing the CMOS Battery:
The simplest way to remove a BIOS password is to simply remove the CMOS battery. A computer will
remember its settings and keep the time even when it is turned off and unplugged because these parts are
powered by small battery inside the computer called a CMOS battery. If we pull out this battery, the computer
will forget alot of its hardware settings, including its BIOS password. This should not be performed on Laptops
if you are not experienced working with laptop hardware.
Anyway, open up the computer case using a screw driver and locate the flat, circular
and metallic CMOS battery. It should look something like the picture to the right.
Some computers have this part standing upright.
Once you have located it, observe how the latches are holding it. There are many
different ways to remove a CMOS battery but the most common way on newer computers can be seen in the
picture below.
Make sure to power down the computer, unplug the power cables and unplug any
USB devices if they are powered. The computer must not be able to get power from
anywhere for this to work. Take out the CMOS battery and wait 10 – 25 minutes
before putting it back in. The reason for this wait is because the computer can still
store power in its capacitors even though everything is unplugged. The waiting period
allows enough time for them to discharge.
Plug everything back in, power up the computer and enter the BIOS again. If everything went well there should
be no more password. In some cases, if you get weird error messages during bootup now, you will need to
goto “Load BIOS Defaults” in BIOS and save the changes to fix them.
If this method didn’t work, try one of the methods below.
How to Bypass or Remove a BIOS Password using Software:
!BIOS is a freeware utility which is designed to be a whole BIOS and security suite. It has the ability to decrypt
the passwords used in some of the most common BIOS makes such as Award, Phoenix, American
Megatrends, IMB etc..
It also has the ability to brute force the password (known as “blasters”). However, this method is dangerous
and can result in some unexpected and unwanted results.
Note: Because of this applications password cracking abilities, some antivirus software may report it as a
virus/trojan. This is a false positive.
To start using !BIOS, reboot your computer and take note of the BIOS type and version you are running. For
example, If your motherboard uses Award BIOS you should look for the text “Award Medallion BIOS 6.0″ or
something similar.
Download !BIOS from here and save it to your desktop. Then, open a DOS command windows by going to
Start > Run and type: cmd

Once you see a black screen in front of you, type: cd desktop
You should now see something like: C:\Documents and Settings\YourUserName\Desktop>
Now type the name of the file you just downloaded, if you haven’t changed the name just type in: bios320.exe
Use the down arrow and choose “Crackers” and then press the right arrow. Using the
up and down arrows, select the BIOS that the motherboard is using and press Enter.
You should now see a menu asking what you want to crack, in most cases its the
Supervisor or System Passwords you want to crack, so press the 1 key on your keyboard. It will then show
you another menu asking how you want it to be cracked. Option 1 is pretty good so try that first by pressing
the 1 key on your keyboard. You should now have your BIOS password.
Reboot the computer, enter the BIOS and try it out.
How to Bypass or Remove a BIOS Password using the manufacturer backdoor password:
On many computers (especially old ones), computer manufacturers build in backdoor passwords for their own
technicians to use so they can access the BIOS when the hardware is being serviced. Here are some of the
ones that have been reported. You may need to try quite a few passwords before you find one that works

Uhmmm, don’t take out the battery.
Just find the CMOS jumper(it’s almost always near the battery), Then move it over for about
five seconds… Then move it back, and Your BIOS will be reset. This is much faster than
waiting for all the power to drain. Some newer boards even have a button instead of a
jumper.

I have a dell inspirion600m. I bought a new dell laptop from ebay over a yr ago, and reg it
online. Now the hd has crashed, i purchased a new one, but am locked out by an admin pw
the prev owner installed. Dell was willing to send me start up cds and transfer ownership,
but that’s as much cooperation as they will give. I’ve not yet found a pw that works. Any
suggestions?I’ve also replaced the battery, the cord, and the adapter for the motherboard.
Dell is telling me I’ll have to buy a new motherboard. Ebay is of no assistance either due to
the time that has passed. I never realized til the harddrive went down that there was a
admin pw. Thanks.

bios saver says:
THE MOST EASIEST WAY TO BYPASS THE BIOS USER PASSWORD (not to enter the
Bios but to enter computer Windows).
1.When you turn on the computer you wait until it say: “Enter Password”.
2.When the first step is done you press and hold End for about 3 seconds.
3.While holding end press Enter and you will be on your way to Windows.

Seems people are getting confused with hard drive passwords and BIOS passwords. If the
password is on the hard drive, these methods wont help. In fact, your options are very very
few if its a hard drive password. For BIOS passwords, removing the battery fixes 90% of
them.

Tim Bob says:
I shall try and help thos of you that have got a bit mixed up.
The BIOS/CMOS password can be reset most of the time by just taking out the battery
from the motherboard for a few hours, sometimes only 15 mins. This can be a bit tricky on
a laptop, so be careful.
Some of you have mentioned getting a meassage that goes something like this, “THIS
COMPUTER SYSTEM IS PROTECTED BY A PASSWORD AUTHENTICATION
SYSTEM….etc….etc”. This is a HARD DRIVE password stored in the boot sector, NOT a
BIOS/CMOS password. I so far have only found one thing that works, and not every time
mind.
If you have acces to another PC/Laptop, download and install the most current version of
‘Window Washer’. I find this a good program for keeping your temp files in check as you
can set it to delete them every time you exit your internet browser. You’ll be amazed at
how much space you’ve saved, just after a few days. Anyway, the section you want is on
tab on the left hand side of the window marked ‘System Eraser’. This will show you, in 2
easy steps, how to make an Eraser boot disk/cd. This disk/cd will COMPLETELY erase
the hard drive of any system that you boot it in, and hey presto, you have an almost-out-of-
the-factory hard drive.
Remember, this is an erasing program, NOT a formatting program, so you will still need to
format the drive after, as it will COMPLETELY erase EVERYTHING. Also, if you have
sensitive data on the hard drive that you are going to erase, you might want to consider
setting it to the max amount of passes, around 35!! This will almost ensure that NO Delete
Retrievel program will be able to get it back. This process may take severall hours to a
couple of days, depending on the size of the drive. This has worked for me around 85% of
the time, hope it works for you too.

Andy says:
Hi
em – why go to all that trouble? Just flash the bios and it resets to default…
simple enough to do switch of and unplug computer. Open side case / locate the bios
jumper on the MB/ generally theres three pins – the jumpre will cover two. Change it so it
covers the one that isn’t and the center pin. Turn on computer. leave for about 5 seconds.
turn off computer and unplug. reset bios jumper back to where it was.
turn on computer and access bios. simple enough no backdoors, no software and no
messing with cmos batteries although the latter does work on most newer machines…
flashing the bios though is probably the oldest and easiest method to do a bios reset..
As to the other chap with the password problem? slave the drive into another
computer/recover data/format the drive – password is gone as is anything on the drive/refit
(as a master) and re-install….

Now tell me how to reset a password from a Toshiba Laptop M35-S320. I have tried all the
methods on the web, I’ve tried parallet port loopback, keydisk,operate the whole laptop out
into pieces and remove the cmos battery cable. There are 2 small green batteries soldered
together, laptop PC is so much different than a desktop PC, the way that Andy described is
so easy for a desktop PC or some laptops, but it did not work in my case where I have this
Laptop M35-S320 I have tried to re-flash the BIOS, but it won’t let me because it’s not even
pass the stupid BIOS password screen before it can detects any floppy drive or bootable
device. I know there’s a way to short out the jumper or EPROM jumper, but I could not find
this on the laptop motherboard, maybe it is somewhere that I couldn’t see it yet. If anyone
has a solution to this, please help.

I have an old omnibook 4150. I’ve tried to disable BIOS password, but the damn thing still
wants a password. The old password doesn’t work, nor does hitting enter or right alt + enter
or del + enter.
I’ve also tried all backdoor bios password I could find online.
Clearing the cmos doesn’t do any good either, it just erased date and time settings, but not
the password request.
Calling HP customer support was total waste of time and money, too.
HP omnibook 4150
Phoenix BIOS 4.0 release 6.0
Hash code 06713
Help will be much appreciated.

total, and pull your laptop hard drive,put it in the case and connect to another computer with
cdrw. Find the files you want, and copy them to the cd. Maybe you could use a friends
computer. My sony vaio laptop hard drive is on the right side with one screw and a slide
latch, then pull it out. Take it out of the case and put it in the usb case, and follow insts
they send. Photos are very important.

I’ve just watched an interesting video of a presentation from Defcon about how to read the

work on others. You have to be able to boot into windows or linux so it might not be so
useful. You will also have to compile it using nasm.

I work for HP, and if you have a system power up password on a laptop. It is customer
damage when you don’t know the password. System board needs to be replaced but not
under warranty.
Had these problems before with company’s who had their employees fired but not knowing
the system passwords of the laptops. And the ex-employee did not want to tell it. So they
had to replace all the system boards under no warranty $$$.
Some laptops were only 2 months old.
Removing the CMOS battery works for the BIOS password but not for System Power up
password.

I have been reading all of the Q and A’s and I have to say this guy Kyle is a real first grade
tech. First off he forgot that not everyone is as adept at computers as others. And if he
would have continued to read he would have noticed everyone is speaking mostly on
LAPTOP computers not a HOME pc. As fas as this being elementary level, by far also not
true. I have an associate degree in Computer Science and many cert. and also I am
emplyed by a firm that deals with things of this nature, and this is by far not elementary.
How-ever another common fix that he forgot to mention is that you can short out the admin
pass stored on the EEPROM setting, which is what HP is notoriuos for, simply by
unplugging the EEPROM board and the CMOS (not bios by the way KYLE) and depressing
the power button for a few seconds. If it doesnt work that way then you can also try
shorting out the cmos password by touching the CMOS battery tips on the board that the
battery plugs into to a seperate grounded peice of metal. Not aluminum or brass, it has to
be metal. You can usually find a piece real close to the CMOS battery plug-in. Hope the
info was helpful. Thanks

Sorry about last post Kyle, Those comments were aimed at ANDY. He seems to be a

Altahost Compure Services says:
I see this kind of response to cmos password recovery all the time and would like to add
my two pennith.
Firstly Battery removal will work if the cmos password was set up by a user after it has left
the factory.
Second, you can flash, restore to original, trip the jumpers as many times as you want and
it will have absolutely no effect if the password was set up in the original bios by the
manufacturer. Simply because it is protected as the rest of the base setup software is.
The best you could do is to retrieve the password that has been created. This method will
work for most secured passwords.
Firstly what you need is a floppy drive and 2 blank disks.
You will need to create a Win98 boot disk.
You will need to download (AWARDBFD.exe)
Search google for it, the one on Drivers Guide is a good copy.
http://members.driverguide.com/driver/detail.php?driverid=134029&action=filfo&t=1
Extract that zip onto the other blank 3.5″ floppy disk.
My guess is your BIOS is set to start Hard drive before CD rom so, disconnect the hard
drive and the BIOS will naturally look for the next bootable device.
Boot your system with the Win98 Startup Disk.
When you have the prompt (Make sure its the A:/) or drive letter of your floppy, insert the
AWARD disk and then type AWARDBPF.exe
Hey Presto, you will see both user and administrator passwords. Write them down and
then enter Setup and type the Administrator Password
Hope this helps :)

This information is intended for experienced users. It is not intended for basic users,
hackers, or computer thieves. Please do not try any of following procedures if you are not
familiar with computer hardware. I’ll not be responsible for the use or misuse of this
information, including personal injury, loss of data or hardware damage. So use it at your
own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the
battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the
BIOS password. The location of this jumper varies depending upon the motherboard brand.
You should read your motherboard manual to check its location. If you don’t have the
manual then look for the jumpers near the CMOS battery. Most of the manufacturer label
the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining
the center pin to either left or right pin. What you need to do, is remove the jumper and join
the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove
it and join center pin to right pin. Now wait for a few seconds and then again remove the
jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost
or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the

keyboard easy, carefully popped the cover over the power button/hinges and unscrewed the
keyboard and poped it out of place. pushed battery carefully to the heavy side of the plastic
and lift and it fell out of place. anyway i called dell and they charge. i have been reading
googled. and found out they give you a maser password from the information that comes
written on your laptop. i would use a software to crack it except the few i found are
questionable at best or charge. there are no jumbers to reset and leave very few options to
recover from any of the bois password lock outs. i am not paying the fellow if i mess this up
so shorting out anything is out of the question. i get that idiots out there steal and such. so
i guess if i am to get the answer i have to pay and pass the buck or let go of this one. my

sorry i dont have the questions answered but someone out there does. i have like 2 of these
in my closet and would love to fix them. but i want to get passed the password thing first.

This is for Desktop Computers only.
Laptops have an eeprom chip and it retains it’s memory for a long time.
EEPROMS are also found in tv’s etc.
you can unplug your tv from the wall and leave it sit for a long time but the eeprom chip
keeps it’s memory.
Another site (I forget where) said they sell the dell software that’s used by the dell service
centers to unlock the password.

Ok – I’ve read a lot of post and tried a lot ‘solutions’ most work for desktops, few work for
laptops…
However – I’ve got a good one here, a Panasonic CF-T5 (typically called a ToughBook), it’s
bios and HardDrive locked. The laptop was originally owned by a hospital, passed via
auction to an employee, which then was passed to her daughter. Neither of them can
remember either of the passwords. I’ve yet to get the cover off to force the reset of the Bios
(as the screws in this thing have damaged two of my screwdrivers) and are very small.
I plan to format the hard drive with Linux once I can get past the bios (as it won’t boot to an
external drive/flash drive/usb drive).
I’ll post an update here on how this went. (may also link some images of this case and it’s
cmos battery location and such)

I have the Answer for all who need a password or CMOS password or hard drive passwords.
(For windows only!) Desktop are as follows. If the BIOS is password protected, Like in
previous posts, All you have to do is remove the CMOS battery and reset the jumper.
Laptops on the other hand my be a little more difficult. Most can be recovered my just
removing the CMOS battery for 30min others need a little to a lot more work. Some as
above have master passwords that can reset to OEM. Some like most dells require you to
call dell for them to try and generate a password for you if the password fails you will be
required to send to dell for them to replace the motherboard because of the BIOS backup
chip located on the motherboard right below the CPU (or if you are truly gifted replacing this
chip yourself). If your under warranty then your fine, If the CPU was given to you just
transfer the ownership on dells support website and your fine, dell will be happy to replace
the board and you are only out 15 days. But if you don’t have a warranty it will cost you
about $50 to acquire a temp warranty so you can get the same service. Those who don’t
want to pay or have gotten there laptop by ill gotten gains are S,O,L, unless you find a way
to replace the motherboard or chip. As for all hard drive passwords on desktops and
laptops, you have two option, a program that creates its own BIOS to format the hard drive
like SecurErase 8 or the ever famous password recovery tools that people like to use ( keep
in mind that those programs need the windows BIOS to create there own so if the BIOS is
locked your S.O.L. As for the second way just use a legit OS and reformat the hard drive
and you will be back to square one. but remember that some ways you will loose all data
and others you just will recover your lost password. I hope this was somewhat helpful to
those don’t know or would like some light shed on this subject!

Let me just get this one straight for you all people ,first of all if you dealing with a computer

replacing the bios chip which cost $29.99 That is for anyone having a administrator
password setup in the bios system.,other option which do work with some models but not
all of them is downloading the bios from HP,Dell,etc then create a boot disk written in dos
system and restart your computer off the floppy disk.
Now for those that have other message that says this computer system is protected by a
password authentication system. you cannot access the data on this computer without the
correct password .
That password has been setup in the bios system but that one will work just fine if you

Dan says:
Wow, Sony Vaio PCG-R505GL, got at yardsale. BIOS is password protected. ONLY Sony
customer service can help. Called them last night. They want $49.99 AND a faxed copy of
a Proof of Purchase. I told them that I purchased this unit at yardsale and don’t have a true
“purchase receipt”. They told me that it would be impossible, due to security reasons, to
help me without receipt. On this laptop (and many other newer laptops), removing CMOS
battery has NO effect on removing passwords AT ALL! You can NOT FLASH the BIOS to
remove the password either. The system will NOT boot to CD or floppy or USB. What I have
read is that Sony IS capable of generating a MASTER PASSWORD (after you pay) that is
associated with your laptop’s serial number. So this is more of a complaint than
anything….SONY, in it’s great wisdom, has completely forgotten that MANY, MANY
laptops are discarded at second-hand stores, flea markets, and donated as “old and
useless” all the time. But these laptops are still useful to many of us who can’t afford a
brand new unit. So although it’s great for Sony to capture $49.99 to recover a lost password
and make a computer USEFUL, they have NO WAY (that I know) of initiating some kind of
TRANSFER of laptops program when we, the general public, comes across a second-hand
laptop. FORGET the THIEVES, they are a very small part and WE shouldn’t have to live our
lives based on criminals. How about a little REAL HELP for the decent people? ~just my
thoughts~

Please call up Dell support, provide the “595b” code and they can generate a reset

enter twice and it resets your settings sending you into the OS. Restart and go back into
the bios to verify the solution has worked before sending tech sppt off of the phone call.

This is for mth420′s dilemma. I don’t know of any programs for generating a admin passord
from the service codes, but if you can find the chip on the mother board where the
passwords are stored you can either replace it with a blank cmos chip for about $20 on
eBay. Or you can try to find someone that actually knows what the Hell they are doing and
have them show you what pins to jump to that would erase the passwords of the bios.

After that, I updated the bios. Downloaded it from HP website and installed.
Since that, I cannot access my bios, because the password I set up is incorrect…
I read that you know how to fix it by downloading the bios from HP and, using DOS
commands, boot it from a floppy disc.
Could you please send me the commands and if you could, The right bios for me to install?
I’m with a phoenix one. May use a CD instead of a floppy disc?

This information is intended for experienced users. It is not intended for basic users,
hackers, or computer thieves. Please do not try any of following procedures if you are not
familiar with computer hardware. I’ll not be responsible for the use or misuse of this
information, including personal injury, loss of data or hardware damage. So use it at your
own risk.
A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the
battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the
BIOS password. The location of this jumper varies depending upon the motherboard brand.
You should read your motherboard manual to check its location. If you don’t have the
manual then look for the jumpers near the CMOS battery. Most of the manufacturer label
the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining
the center pin to either left or right pin. What you need to do, is remove the jumper and join
the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove
it and join center pin to right pin. Now wait for a few seconds and then again remove the
jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.
B. By Using Software:
I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost
or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the
program, and get access to forgotten BIOS/CMOS passwords in just seconds

First off, the post title doesn’t specify desktop or laptop so some of you need to be a little
more cautios before insulting others. Secondly, not everyone is PC tech saavy, that is why
these post exists because people don’t want to pay business’s high fees for something
they can do themselves. Third, there have been a few posts stating that the Dell message
‘this computer system is protected by a password authentication system. you cannot
access the data on this computer without the correct password . please type in the system
or administrator password and press enter’ is a Hard Drive passwaord then they had the
nerve to call the people asking for help idiots. Well it is NOT a hard drive password, it is not
even a bios password but a ‘System Boot’ password. The easiest way to find out if it is a
hard drive password is to REMOVE the drive and turn it on, with NO DRIVE in the laptop
you will still get the massage.

Acer laptop bios locked no o.s on HD Will not boot from cd
The fix. Easy and it always works. Cd rom and HD in laptop remove the HD and using a
external HD case 20 bucks put the HD in that connect it to USB and boot pc Now you can
boot from cd cuz hard drive is not present (we moved it to USB HD ) now when you install
the os to your external HD you might get a error during second part of install this is suppost
to happen b.s.0.d
simply put your HD back in laptop and reboot now you can finish the second half of xp
installation and the bios dose not need to be unlocked cuz your os boots fine. I just did this
with a travelmate 5520 and it worked like a dream

Laptop Unlock says:
you CANT erase this password just by removing rtc battery, you have to get a master
password based on the hash code .
The hash code appears after entering 3 wrong passwords it has a 5 digit format “xxxxx”,
you can get your laptop unlocked at Laptop Rebirth

Hi, i am using dell inspiron 1300, whenever i power on the system an error message come
which says that there is no boot device. I try to format the system but i am not able to do
that since the default boot order menu is internal hard disk, i try to set it to cd drive but it
says that it is password protected. I need to remove the password, i follow your instruction
to remove the cmos battery, i unplugged the battery from the system board for about an
hour, when i start the system again the date and time section load to default but the
password protection is still there.
Please help me!

hi i have few suggestions on all of these matters first of all bios password removing is
almost impossible in most cases because we are not all expert programmer when i had a
problem with one of the laptops i used a program called bios password remover had to be
used on boot up which i think is the best way to crack a bios password but in one of the
laptops it crashed it i took it to a repair shop they told me it is not fixable anymore then i
took it home taken it a part i took out the processor chip and turn on the laptop it made few
noises i turned it off and put back the processor chip back and turned it on again guess
what no bios password and laptop is still working still i wont advice anyone to do all that
unless you are willing to lose your laptop for good lets get back to the windows password
there is few ways i know how to bypass that it is all tryed and tested on lots of laptops so i
am talking from experience
1.if you are worried about loosing your stuff on the hard disk take it of then plug it in
external reader which costs around £8 pounds transfer all your files at another computer
then put your hard drive back and install new windows on it here you go
2. you can install windows vista if your system is capable vista keeps your files on place

called an old windows get your files out re-format with any windows you want format all old
windows so they dont keep extra space on your hard drive this works with windows 7 is
well
i hope this helps

Hi, I feel like a total retard, but I’m not sure what kind of password is on my computer. It
worked fine til one day I went to boot it up, and as soon as i hit the power button, it went to
a black screen with a blue box that says “Enter Password.” Nothing else… I dont know if it
is a bios password, or a hard drive password, or what. If someone can help, it would be
greatly appreciated. By the way, i tried taking out the cmos battery, and that didn’t reset it.

Gerry says:
People please note that much of the above information is not going to work if you have a
Dell Laptop and the screen is reading DATA PROTECTION password, the only sure way is
to go via Dell and follow thier advice. This system is designed to help stop thieft, the pass
word is in fact a secondary bios password but is in fact not written to the bios chip but
rather is stored on a special chip and not as some have claimed stored on the boot sector
of the HDD.
Take care in what advice you follow as there aqre a great many fools who think because
they know the difference between a laptop and a desktop, think they are a tech, if you are
not carefull you can stuff your comp totaly

“jumpers dont exist in laptops”, I looked for a while where those bl**dy things were on my

if I can getfurther than the BIOS screen…
If anybody knows any “master passwords”, or specifics for Dell Latitude machines, please
post :-)

I waited overnight, but the BIOS start up screen is still there.
Dell as a BIOS password does not work.
Buying a laptop over E-Bay is perhaps not such great idea…

LOL.
What a statement:
“NOTE: Do not try to guess the password on a passworded Hard Drive. 3 wrong guesses
will often result in the information on the hard drive being lost forever.”
As if, lol, imagine the lawsuits, you have entered your password incorrectly three times,
now securely erasing your data… LOL
Obviously the original author doesn’t doesnt really know his/her subject…
After three times, the hard disk freezes until the next power cycle…
