I've had a lot of crazy things happen to me while in the process of rebiulding Dell laptops and can't say I have all the answers, but I'll sure give it a try. Right now I have two puzzles I'm working on. I'd like to break a dell inspiron1000 master bios password that denys access to the computers system. I believe the only way to fix it is to replace the mobo. Dell won't even guarentee that thier master password for $50.00 will do the trick, This is a little more technical. I'd like to replace the bios on a Dell d600 motherboard without distroying the boards integrity. I could replace the entire board . This would be the easyway out, but I would just like to be able to say that I can do it. It looks tough but I'm sure they'res a trick to it that I haven't found. There has to be someone out there with the knowledge.. So far it's been slim pick'ins in the information bank. Replacing the bios usually cures 60% of the mobo's problems.
