Hey all,
Working on an HP Pavillion G7, and I'm pretty sure the motherboard is gone, but I'm not positive. I've tried the obvious things (removing the battery, letting it lose all charge, reseating the RAM and hard drive, etc.) Here are the symptoms:
- When turned off, immediately comes back on (even if you hold power button down and it shuts off...a few seconds later and back it comes); only way to get it off off is to take the battery out and unplug power.
- Screen tends to start flickering and occasionally display a bar pattern; this is intermittant.
- Sometimes beeps for over a minute when started (it's NOT a beep code...almost like a key is stuck, but none seem stuck; this comes and goes as well).
- In BIOS screen, if something's highlighted like, say, the time, it'll be fine, then start jerkily decreasing (again, like the down key was being pressed, but it's not...and temporarily stops if you do press it, but then starts doing it again).
- Doesn't try to boot to the hard drive; goes to some UEFI browser instead, but that seems bugged/slow.
I did get it to complete a memory test successfully, but other than that I can't get it to do much.
Ideas? Would it be worth investigating anything by taking it totally apart, or is the MB definitely hosed?
THANKS!
