Aight... So what i have going on is a computer that has a keyboard that certain keys arent working like enter and the letter E and other parts. cant tell you everything since i cant get past(choose operating system to use.. press enter...) So... what i did was get a new keyboard.. The new keyboard has the same keys non-functional so i bought a new keyboard for nothing it looks like.
Questions...
1. I head there is some sort of "protection" on keyboard circuits that will actually lock out certain keys... i wasnt sure if that was bupkis or not, It stated that you had to leave the laptop totally unpowered(pull bios chip too) for over 24 hours... is this a real fix or a ruse?

2. If that cannot fix(which i am trying to do now... 24 hours is a long time to ponder how to fix.. lol) What are my other options as i know that it isnt the keyboard that is cuasing this problem.
Could the motherboard be bad. i looked at the pins for the keyboard connection and they all seemed fine... Could this in fact be a keyboard controller issue? And if so... how can this be fixed... or can it not?

3.. Thank you for helping.. im stumped to all heck and i really dont want to give up on this. its a friend and he isnt a rich person. im trying to help him out.
