I have a serious problem with my HP Pavilion ze5155. Let me start from the beginning of the story to give you the "full detail". I was interested in an HP Pavilion laptop, so I was recommended for the HP Pavilion computers. I purchased an HP Pavilion ze5155 and everything ran fine for a while. It came to about 4 months ago and the power plug on my computer (which is connected to the motherboard) shorted out. I sent it in and they replaced the motherboard for $450. Now, I am having more motherboard problems. It ran fine when I got it back, and just a week ago the fan started making "odd" noises. On my desktop, the power supply fan made this noise because it was dirty in the tower. After vacuuming it was fine. I thought this was the problem but emailed HP support just in case. They said that I needed to install a BIOS update. I noticed that when I tried installing it that it said it wasn't compadible with my PC. I emailed them back about it and they said that it should work, since the download site matched with my product name, so I ran another file and then it restarted and now when I boot I get a blank screen. I've built a handshare of computers, and from what I recall there are a few different ways to reset the BIOS on this kind of laptop. I was wondering if anybody has ever pulled this kind of procedure, and if it is for sure the motherboard BIOS. I think there is a reset button or some battery? Anyhow, I'd appreciate the support....thanks!

Jump to Postif it is soldered on, i would not recommend trying to pull it off at all. Now there is no lever to pull it out, its just a matter of pulling it out, here is a pic of what it should look like http://www.infopackets.com/graphics/cmos+battery.gif if your battery looks …
