Question about IBM ThinkPad T23 2647 Notebook
I have forgotten my T23 2647 power-on password and I have tried the follwoing with no help:
1. Turn off the computer.
2. Remove the battery pack.
3. Remove the backup battery.
4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed.
Do you please have any other idea. I need my laptop asap.
The power on password is stored on an EEPROM chip and removing the BIOS/CMOS battery won't help.
You need to read the EEPROM chip to get the password.
for solution to your problem (you need to construct an interface hardware and install two programs on a working computer)
