Barck the Power On Password

This is a bios password and very difficult to crack, removing the power supply, main battery, and the cmos battery on the motherboard will not reset it. Go to www.ebay.com type bios password and select IBM from the list of sellers.

you will have to re install your opperation system

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.

please you need to reset its bios. open the screws behind your laptop with keyboard icons to access your laptop cimos battery with care remove it for some time(3min), power on your laptop until it boots up. turn it off and put the battery back. the password will removed.

You have a Power on Password. The correct password has to be entered before the laptop will bootup. The password is set to prevent unauthorized access to the laptop.
Did you purchase this laptop from someone? If so get the password from them. There is no backdoor password and the password is stored on an EEPROM chip so removing the BIOS battery will not reset the BIOS and remove the password.

If only the power-on password is set, do the following to remove the power-on password.

1. Power off the computer
2. Remove the DIMM cover on the bottom side of the computer.
3. Short-circuit the two password pads or put a jumper on the contacts to short the circuit.
4. Under the short-circuit condition, power on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The power-on password is removed.
5. Reinstall the DIMM cover.

If both the power-on password and the supervisor password are set, do the following to remove the passwords:

IBM BIOS power on password, hard disk password are stored on an EEPROM chip and is almost impossible to crack. There are no backdoor passwords available.
These password protection are set to stop unauthorised access to data on the laptop, also moving the hard disk to another computer to read the data off the hard disk will not work either.
There is a way to hack into the EEPROM, but requires electronic hardware skills to build a reader device, a working computer and software.
