The Power on Password is set up from the BIOS configuration and the password is stored on an EEPROM chip. Removing the BIOS battery will not reset the BIOS password, there are no backdoor password available.
There is a way to retrieve the password, but it requires a bit of electronic skill and a working computer to achieve this.

If you've lost the bios password, you'll probably have to 'flash' the bios. If you feel comfortable enough, you can dismantle the laptop and remove the motherboard battery for several minutes, then replace it and reassemble the system, see if the password has been cleared. (Note: The motherboard battery is NOT the laptop battery; you have to remove both!)

I have IBM 2628-DRU Think Pad A21m And this PC sets password for BIOS, and I can't use it, because I don't know the password


To reset the BIOS read the information from this link.

In case of your laptop the easiest method would be using software from Hiren's Boot CD as it's pretty hard to open it up and reach for the CMOS battery or the jumper.

I forgot the master BIOS password. IBM thinkpad 2628. There`s no start possible. Additional I get several error information: Error 271 Ceck date and time settings Error 251 System CMOS checksumbad- default...


disconnect the intal cmos battery, there may be a jumper near by, j1 or something like unconnect the jumper, whilst the cmos battery is disconnected switch on the laptop, then let the post screen load, switch off, re-connect the cmos battery and re-enable the jumper, switch on, should work fine now, if you don't see the jumper, you won't be able to reset the bios password, refer to a service manual for your laptop model for the location of j1.

Cant remove my bios password on my IBM Thinkpad A21m


Dear Sir,

Getting around the Laptop BIOS password is tricker then the desktop...I don't know if your system would go passed POST or not...in either case, there are few software out there that would allow you to clear the bios.....but you need to do some reading first...

Check out this site: http://www.i-hacked.com/content/view/36/68/ search for this section "Password cracking software" , you will find four software which may help you out (please note that you have to be registered user in order to download the software.

Enjoy..

Start the computer and hold down the DEL Key (this is usually the key to enter the bios once you enter the bios there is a section on passwords and you can sometimes select no password Another way is to remove the bios battery for a minute
