I lost sound, touchpad/click control, and one USB port on the left side, as well as my ability to turn on or off the laptop with the power button (it would no longer light up, either), but I could still run the laptop if I used the Quickplay buttons, and restarted with f12 to let it boot on it's own. Then it would go into Windows and work fine (except the above-mentioned problems).
So, like any sensible computer tech, I replaced the motherboard. Unfortunately, now I cannot get it to power on at all. I have quadruple checked the connections and tried 3 different motherboards that I knew to previously work, including the one that had the failure but would still boot. So, I know I'm missing something really stupid but what?
There is an LED on the motherboard on the opposite side of where the power comes in, and that lights up as it should. Without a battery, the charging light, as it should, turns off.
I have also replaced the speaker bar that contains the various power on methods, the touchpad assembly, and because I had a spare, I even replaced the PC board that the power plug enters at. Oh, and I replaced the keyboard. The goal was to replace everything, and all that's left are the ram sticks (both wouldn't fail at the same time) and the harddrive. However, the computer would have still turned on with none of those connected, which I tried.
So, I've replaced everything necessary and tried 3 different motherboards (plus the new one) but I still cannot make it power on. Ideas?
Incidentally, everything worked fine until I CAREFULLY disassembled it to fix this problem. Tell me what else you need to know to troubleshoot this. Thank you.
I have performed 4 previous and successful motherboard swaps on this laptop, a successful upgrade (and then later downgraded) to a DV9000 mb, as well as built several of my own computers and was a computer tech for hardware and software for a few years, so my skill isn't an issue.
