Ok this is part two.


this is what I found out I took that laptop computer to pc parts and supply and have them test with their adapter and it did the same thing now I'm stuck wondering if my AC adapter could of taken out the motherboard. How can a AC adapter go bad?


Thanks.

Spiderman.

I had them test my adapter and it was in dead bad now so I guess it could of taken out my old motherboard and could of taken out the replacement motherboard to.

Scott what do you think. and I also wondering could it cause any other damages to the CPU chip video card or the memory or the hard drive or the dvd-rom/cd-rw drive and cause it now to power up?

I have other a new ac adapter a dell the same one and a new battery too and i talk to the seller and i hope they will send me a replacement motherboard.

The computer tech guy at PC parts and supply don't have a clue.
I guess he never seen a laptop computer do this before. I told him that I'll try a new one and if that works with the new AC adapter and battery great then i have my old laptop computer back and then I'll do a clean reinstall of the o/s and clean it up. if not then i guess I'll put back the old motherboard back in and load up the shotgun and shot the DELL S.O.B.

AC adapters fail all the time, however normally when that happens they simply go dead and don't put out any power at all. That wouldn't cause any damage to a system, it just wouldn't receive power. In some cases when failing the voltage will be less than what it is supposed to be. That normally wouldn't cause any damage either, the system would simply not charge or power up. I believe it is rare to have one fail in an over-volt condition, which could possibly cause damage in the laptop motherboard and possibly other components in the system. Most of the time this happens when somebody plugs in the wrong AC adapter, one with either a different polarity or a higher voltage. Scott.
