I have an old HP laptop from 2009 (G61-320US) that for some reason is not working correctly. The computer boots up, but black screen. No beeps, but power light remains on and you can tell fan is running. I know a little about computers, but not that much :-).
-Have had a wacky battery for years now, that it needs to remain on charger at all times to boot up or keep running, so I think battery won't keep charge - but think battery and cable are OK for most part.
-Tried to reset BIOs doing the thing where you hold down the windows key and B, then power button, then release – nothing L
-Checked screen with bright light to see anything - nothing.
-Removed battery, held down power button for 3 min. to discharge any energy.
-Removed and reinserted RAM (and switched around slots – 4 different ways), tried starting each time, no success.
-I even cleaned the RAM slots and removed any dust (with bulb air blower I have). Made sure to not touch any contacts, etc.
-Ordered new RAM online yesterday to see if that will fix the problem, will try when it comes in. Although I will feel guilty about spending the money if that does not fix the problem and it’s just a dead motherboard.
Basically, I wanted to know if there is any sure fire way to see if the motherboard is truly dead? Is the motherboard even worth replacing considering the computer is so old? Also, I am not sure if it is even worth having a technician look at the computer if the computer is so old, and maybe I should just get another one? Sorry this is so long winded, hoping someone can point me in the right direction and/or maybe something I have not tried yet? I have heard about using the oven to reflow the motherboard – but I am sure I would screw something up with that J.
