How to fix BIOS corruption

My 1 year old son loves pushing buttons on my computer. Most of the time I catch him and get him away fast enough it does nothing but this particular time he got my computer turned on and then back off. I didn't think anything of it but when I came back a few hours later to turn it on, the screen was blank and the LED lights by CAPS/NUM lock were flashing in a sequence of two. I looked through my manual and troubleshooted everything they suggested. Then I called tech support and spoke with a woman who's accent was so thick I had no clue what she was telling me. By the time I figured it out I realized she wanted money from me because my warranty had expired "104 days ago". Really? Just to turn my computer back on??? So my mom said, "Go on my computer and Google it. And so I did. And this suggestion was the first thing to pop up. So I tried it and it worked instantly! Who knew it was as simple as taking the battery out? And I'd have had to buy a new warranty for someone to tell me that? Thanks Jack4all. You really know your trades :)

Thank you Jack4all. Had the same problem and your solution worked for me also.
