Hello all, I'm new here and in need of a little bit of help!
My HP zd7005qv laptop stopped turning on a little while back, and at first I thought it was a fried HDD. However, I also noticed that when I plug in the power cord, the lights would blink only for a brief moment then immediately go off. So I started fiddling with the cord and I got it in a position where the lights would complete their start-up blink, and when I tried to turn it on it actually started booting. But it stopped as soon as I moved the power cord again.
So I figured that the problem was a bad power jack.. it's pretty common from what I hear. I disassembled it, desoldered the power pin, and soldered a new one I bought off eBay. Now there is absolutely no problem with the power jack as the battery will finally charge, but the laptop still wont turn on. I'm afraid I may have screwed something else up while disassembling and reassembling the laptop.
When I press the power button, the lights at the top come on, I hear a light whining buzz and then all the lights shut off. I tried removing the RAM sticks, I even removed the HDD and the same thing happens no matter what. I also tried turning it on with just the AC adapter, and I even let the battery charge a bit to try tuning it on with just the battery.
I did need to remove the heat sink in order to gain access to the power jack, and it was kind tough to put back in. Is there a special trick to reinstalling those?
What do you guys think? Burnt processor maybe?
