Hmmmm...no one even wants to guess? You guys all have such great minds when it comes to desktop rigs, but throw a laptop problem in your face, and you all clam up.
Seriously though, this is a great forum with great information...but I think we need to find a few laptop guru's. Does anyone here know anyone that does laptop repairs? I think that most people just send their laptops in for service when faced with a problem.
I think what Dell would do in this case is to just replace the motherboard, dc power board and be done with it. Then either charge you a small fortune, or let the warranty suck it up....whichever is the case.
Another thing is the age of this laptop...its worth $300 max. Most people would just junk it, or sell it for parts on ebay.
Ok I'm done rambling, so now brainstorm
with me on this damn laptop!
Ok, I'm spilling the beans on what I suspect is the problem. Since the AC adapter is new, and works like a champ, I eliminated that. The battery is run down, but not shot, so eliminate that. The DC power jack is fine because the laptop runs on adapter power for as long as its kept plugged into the wall. So, I think that somehow the DC power board became damaged when it was loose, and now it fails to function properly. One of the functions of this board is to charge the battery. I just ordered one and I will update when I get it installed. Keep your fingers crossed for me. Thanks!
