I have a Dell Inspiron 5150, when I try and turn the power on it DOES NOT turn on! If I have my power cable plugged in the power light flashes breifly and then it does nothing.
Now I have read this has happened to quite a few poeple on different boards and such. After going through all the trouble shooting steps (there is a post of that on this site as well) the dell support people say it's a bad motherboard and to send it in. Problem is it's OUT of warranty and am a broke college kid, so it's either fix this or be sol!
I think (and many agree) that it is a power issue. One person in particular had the same problem, he said that a computer-tech told him one of the small 8-pin IC's that manage the power looked bubbled up and was bad. He replaced that and viola it worked!
So I took apart (yikes) my laptop and saw that those IC's look ok. But the little silver ones that were under a heat sink look a little yellow and discolored due to heat. The chips have the numbers MR 6603 0055 0323 on them but on the motherboard they are labeled as PQ94, PQ95... and so on. Also there are three large chips directly underneath the silver chips. The numbers on them are OR7BL 2 3932Q... anyone know what these chips do?
Questions:
1. What does the PQ designation mean?
2. Is it ok for these chips to look a little burnt since they are directly under a heatsink and are then apparently meant to dissapate a lot of heat? Or does this maybe mean something is wrong?
3. Do you think they look bad?
4. Just in general... what's wrong
?!?
So here are pics of this from my crappy Treo 650 cameraphone... I'll try and upload high-res pics so you can see the discoloration better soon.
Thanks for the help!
