Hi! my computer has started acting crazy. first I needed a new AC adapter as mine was frayed. When I got it (off ebay, not a dell brand) it worked fine, but after a week I got a message AC adapter type cannot be determined. So I bought a new one from Dell thinking that would fix it. The new one worked for a few days, then did the same thing. Now sometimes when I move my computer with the adapter in I get the blue screen. I have had to restore my computer 3 times this month as it will tell me it can't read the hard drive at start up. Press F1 to retry.. nothing works. it will go into BIOS (?) so I put it to boot from CD and restore it when this happends. Then it works for a few weeks more. But still I keep getting the blue screen, and it keeps telling me it has dirty files, or can't read hard drive. Also the adapter error pops up every few SECONDS then won't for an hour or so, then 50xs in a few minutes. Please help!! My computer is only 3 years old!

If it is working fine with a fresh battery then it is not a motherboard problem. It is either a bad ac adapter jack on the motherboard or the actual ac adapter cord is not working. Try cables2go.com as they have replacement ac adapters for almost everything under the sun. Hope this helps.
hi bro what u need to do is ... understand when u plug in the ac adapter the light on the ac adapter goes off and whne u unhoook it it comes on .. right there is a possible static charge in the mobo bcoz of which the ac current is nt able to flo on thru the wires to the motherboard .. what u can do is turn ur laptop off completely unhook the ac adpter and take off the battery as well press the power button for 15 sec press and hold it do this xcersice .. hook every thing up and try to charge the battery again it should work .....second possible thing can be may be the connectors on the mobo can be bad on the pin in the prong on the ac adpter must be twisted ,,, so check for that as well ...if still no go then either problem with the onboard power connector on mother board or the whole mother board power aseembly IE replace the mobo ....
Sounds Like From Your Description That You Need Your DC Jack Repaired/Replaced..
THe DC Jack Is the Port where Your AC Adapter Plug Plugs into on the laptop.... THis can be proprietary or non proprietary.... But Either way, the Old Faulty Jack Needs To Be Desoldered and Removed, THe Board Cleaned and a New DC Jack Soldered On.. You Will Then Be able To Power On Laptop With AC Charger and Will again Be Able To CHarge The Battery..
You can use an adapter with a lower or the same voltage, but not higher voltage. Also it should have similar amperes. Also it needs the same polarity. That's the +/- indicator. This page has a positive polarity symbol:
There's no need to pay ridiculous amounts of money for an exact brand name adapter.
