Need to Crack my Bios Password

watto · #1 (**permalink**) 08-12-2008, 02:48 AM

Hi Guys, not sure if this is in the correct section, but I need to unlock bios password.
My wife has locked the bios and now it will not boot. I have run out of warrently so I need to do this without paying if this is possible. I need to get into this tonight when I get home from work....

All help is appreciated.

Well, step one is not getting your wife so angry in the future. (and trying to bribe her for the password...)

Next, who is the manufacturer of the motherboard? Or, if this is a computer made by a major manufacturer, what is the make/model number of the motherboard?

There are a few possibilites. Some motherboards have override passwords that might work and allow access to change or disable the password. If that is not the case, a hardware override might be necessary, which would involve resetting the BIOS, if that is possible on your motherboard.

If you are on a Windows Pc and forget your Windows password, you can make / download (don't have the link) a Linux upstart CD from another computer to find the password

I do not know if that is possible with a BIOS password, since that is a deeper problem. Probably not, since the BIOS password comes before any OS is booted.

Try removing your CMOS battery and it'll default back to factory settings... no password required.

remove the power cord

open the case

remove the CR2032 battery

use a screw driver to short the circuit or connect the bars

wait 1 minute

put the battery back

plug the cord back in

the Bios should be reset.

set new passowrd to "mistress"

That's how I've done it in the past myself...

Good luck and let us know how you end up getting in... =o) We've all done something like it once or twice lol

There are technical ways which are complicated to explain. a simple way is to play at her own game (but remember no SEX for a month...) (1) exchange the password for tv remote control which you have by now. (2) change password in her mobile phone (death)
If you have access to the web from hospital bed let us know how you got on.....

You can't win, give her the damn computer and go buy a new one.

Presumably you do mean for her only.

For all motherboard, there is a jumper that allows you to reset the bios to default. It is near the battery. There is 3 pins where in normal state, 2 pins is already shorted with a jumper. What you need to do is to remove the jumper and short the center pin and the next pin that was not shorted in the normal state. Wait for 20 seconds or so, then remove it and short back the normal state.

That will work. I have done it for many clients.

Hope this helps.

Thanks for the feedback guys. The laptop in question is an IBM t61

I'll give a few of your tips a go......

Well, most of the tips are based on PC desktop. For laptop, it will be kind of hard to do the above tips as you will need to know how to open up your laptop to check. The battery mentioned is the cmos battery located on the motherboard so you will need to dis-assemble the laptop to be able to see it.

Here is a link that you can try the method:

No guarantee though.

The easy way on a Pc years ago was to remove the battery for some minutes. On laptops it is more complicated. Technology that I do not fully understand is more complicated today. My questions:

Is there other ways to store the password than by the battery? If not, removing the battery should be enough.
A person I helped on phone did say that removing the battery was not enough to restore a laptop to factory setting. A Linux Cd had to be burned to find the Windows pasasword. I had no chance of controlling that. May be a misunderstanding of the internal system battery and the external power battery. Did I explain the difference? I don't remember. Probably yes, since I told that it is more difficult on a laptop than on a stationary Pc.
A BIOS password is deeper. Can it be "burned" in some way?

Storing sensitive information on a computer where you can remove the battery to get the information. Is that secure?

For cmos battery, it is the internal battery (similar to watch battery - flat type) located on the motherboard. Depending on the laptop, some covers opening can view the cmos battery to remove and restore the default factory setting. If not, then you have to open up the bottom casing (need some skills as the casing is normal cache on the side - sort of like clip form).

What do you mean by 'burned' ?

**wige** · #19 (**permalink**) 08-13-2008, 10:53 AM

IBM Thinkpad laptops take special security precautions to protect the BIOS password. The password is encrypted in EEPROM, which prevents deletion or reset of the password through removal of the battery (I believe there is a capacitor that stores enough power to retain memory for days, if not longer) and there is no jumper to force a BIOS reset. You would need to follow a special procedure to dump the EEPROM and decrypt the password. There is a tutorial here: Service Forum :: View topic - [Tutorial] How to unlock ThinkPad supervisor password

Your best bet would probably be to bring the laptop to a local computer shop and have them reset the password though.

By "burning" I mean a form of digital fingerprint.

IBM computers are sometimes different form other computers. Years ago, my IBM PS/II had different formatting options, e.g. low level formatting. That took a least 6 hours on mine. Ordinary formatting on my Compaq computer took minutes.

I did this when experimenting with Windows and OSII. Installing, deinstalling and reinstalling.

Agree. That was my advice to to restore the password on a Dell Laptop, even if there could be a misunderstanding of internal and a power battery.

Laptops are (was?) more difficult to handle than stationary computers.

Such distinction re. types of formatting has always existed, and continues to exist, independent of manufacturer.

"Low level" formatting is the actual physical formatting of the drive; "high level" or "quick" formatting is the logical formatting of an already physically formatted drive.
