Howdy. About a week ago, my laptop was working peachy keen, no problems at all. I don't know how it happened, but all of a sudden, none of my AC adapters seem to work. One of my adapters just plain doesn't work on it at all, even though about a week ago, it was doing perfectly. The other AC adapter I have won't work on its own. I have to sit there and actually hold the stupid thing in for it to charge. Even the slightest movement will make it so that it will stop charging the laptop and I have to take it out of the plug-in and reapply it, several times, and in different positions to get it to work again. Also, when it's not propped up against my legs, the AC adapter will start making a weird high pitched hissing sound, which seems to be coming from the computer. Can someone please explain what the hay is going on here?! My arms are starting to hurt...=/ Thanks!

I think the connector in the laptop has broken loose from the motherboard and making intermittent connection. Remove the cable, reach in with your fingers and see if the connector is loose. That can sometimes be repaired by re-soldering the connector to the motherboard.

It sounds like the contacts where you connect the adapter are loose. I can't advise you on how to remedy that except to take it in to a service depot. You may have banged the plug and bent a contact. If you are using the laptop in your lap with the AC adapter in then it is going to move around. You should probably read your manual to find out the recommendations on using the AC adapter with a battery inserted. I understand that varies from brand to brand and possibly even model to model. The battery may not charge while the unit is in use with the AC adapter either.

Aegis: I did as you suggested, but nothing is loose, at all. =/ It's still very much sturdy. Thank you for your reply, though! OtheHill: I'll definitely search for the manual. Didn't even occur to me to do that...I'm a simpleton. =) Thanks!
