I know there's a thread about Thinkpad passwords, but I found a rather PITA way around mine.
I was given a ThinkPad 600 with a password. After some research, I found a way to reset the power-on password: close the shorting pins located near the memory slots. This didn't help with the superuser password (the error 161 and 163 appear without a way to set the date and time).
This weekend I found another Thinkpad 600 in a pile of junked laptops. This was basically the motherboard, display, and shell. The CD, battery, hard disk and memory had been removed. On a whim I moved the drives and RAM from the password-protected model to the junked one. Surprisingly, I could set the date and time. There was no supervisor password on this one! Woohoo! My joy was mitigated with the fact that the hard disk had a password. Rats!
Currently I'm planning on placing the motherboard from the junked laptop into the working one. I would like to use the hard disk, but I could care less what was on it before. I only want to wipe the drive and start fresh. Connecting the drive to an external USB enclosure only causes the drive to attempt to spin up repeatedly due to the password protection.
Any suggestions on making the hard disk usable again?
