One of the fans on my HP Pavilion zv5000t started dying, so I was lucky enough to have a complete same model that I have for parts. I replaced the fan with the parts laptop, booted it back up, and now I have some really weird things going on.

When first turning it on, I get a "compaq" logo rather then my HP logo (before windows loads), next it will no longer run off the battery (not a big deal, I never use the battery), I have to manually push the wireless button to turn the wireless on everytime I boot it up, and finally I have to raise the brightness level of the screen each time I boot up.

Once the laptop is up and I have done everything it runs like a champ.

Im guessing when I switched the fan I must have reset something, or loaded some old bios, but when I go into bios its still the same version, and I have all of my normal bios settings including the bios password I set.

Attempted fixes: I put the old fan back in, I tried updating the bios to the newest version, which I was a version or 2 old, the update went through fine, but no change. I completely took everything apart and reconnected everything. Still having the same results.

I contacted HP's chat, but you know how that is, one of the chat techs told me the only way for this to happen would be if I replaced the motherboard, and he asked me 3 or 4 times if I was sure I didnt change out the MB.....the other tech said the fan must have caused it, and to try putting the old fan back in, or sending it in for a analyss from them.

Im not expecting much of a fix here, but I thought the whole thing seemed really odd, and was wondering if anyone had any suggestions or ideas on this one.

I work on desktops and laptops for a living, and have completly rebuilt hundreds...mainly dells though....although I have taken my HP apart many times for cleaning and other things.
