Hi, I'm unlocking at themoment my Dell Latitude D810 with LA-2631P motherboard and EEProm 24CO4N chip. Here is link for picture Code: http://img401.imageshack.us/img401/963/la2631p24co4not0.jpg First when I bought it it gave me gray screen so I opened case and started to look for EEProm and I did found it under videocard.You can see it from picture,pen is pointing it. It is upside down so pins start from Upper Right corner. I got good advice to short/ground pins 5 or 6 and at certain time when powering up comp. So I used some tape to safely secure to hold 5 inch long string of wire which I attached to pin 5 and replaced videocard. Wire had to bent first to come out from under videocard. Then I connected screen and started up and immediatley grounded this wire with videocard metal core. I had to redo it many times and then I found that my HDD (string: T24T622HN7N-595B) is locked. So I need help with that. I did download punch of progs. and I'll keep posted how I advance with my unlocking saga.
