Ok, long story short; I’m a complete novice but I’m being forced to make the following in order to read the eeprom from my Thinkpad T41 laptop and recover the supervisor password:


I’ve had trouble finding a supplier that will do small quantities but came up with the following:

I’ve found the correct resistors but I’m a little confused as to whether the Zener diodes from pack 10:

http://www.fastcomponents.co.uk/product_info.php?products_id=36

are suitable as they are of the BZX55 rather than 79 specification, having no real idea what that specification means and being unable to find it elsewhere I’ve come here. I have a rudimentary understanding of what a Zener diode is and from my understanding there shouldn’t be a problem. But I’m not really willing to just go ahead and find out either. So whilst this is a massive long shot; any help guys?

Unfortunately guys, no, this is the –only- way to recover the supervisor password and retain all data stored under the HDD under the same password at this stage – save having hypnotherapy to recall the password.

Yes I was going to buy those entire multi-packs just for two diodes and two resistors. The price really didn’t bother me because the alternatives made this look cheap and more practical than buying a few hundred of the same plus I could grab PCB at the same time. Although the idea of being able to make resistor people and animals sounds good; I would be massively appreciative if you had some of those you didn’t need. Email on the way Thanks.
