My computer will not charge.

I agree with bherman503

It could be something internally inside the computer, It could also be the power adapter also. Try using another power adapter to see if it will charge with the power adapter...or it could be the battery itself. If you have a warranty with the computer call the warranty company as they usually will fix the problem whether it's a piece of the hardware inside the computer, or if it's the power adapter will send another power adapter, if it's the battery they will send you another battery.
