battery not charging

[tanhinha]

am having a problem with my dell vostro 3560
Error massage
"the Ac power adapter wattage and type cannot be determined.
the battery may not charge.
the system will adjust the performance to match the power available
please connect a dell 90W AC adapter or greater for the best system performance.
Strike the F3 key (before F1 or F2 key) if you do not want to see power warning message
strike the f1 key to continue, f2 to run the setup utility"
The central pin in the 90W adapter looks fine and the battery works however am using the computer pluged on mains coz the battery is not charging . Given that my warranty is finished and Dell support doesnt help much once warranty is up, please help?

Are you using the original adapter that you got with the vostro or did you by chance happen to have bought another one?

It sounds like a problem of incapability, have you tried to turn on your laptop with either battery or adapter connected? Then we can identify the problem component.
