Dell latitude no power on

[quartz]

Hi,

forum has already identified a cap in a display power board, thanks, hoping some luck with this.

Have a dell latitude d400 (second hand), been using ok for 12 months. a week ago, it was switched on all ok,4 hours later, came back to it and it had died. state of play is....

as soon as i try to turn the laptop on, the LED on the power block, goes off. have to remove the ac adaptor from the mains, to get the power block LED to go on again. the moment i try to switch the laptop on, the power block led goes off again

when attempting switching the laptop on, the laptop power button light barely flicks on, and straight off again.

ive tried switching on with no battery and no hard disk installed, also reseated both so-dimm modules. i'm guessing either the display, or the laptop motherboard itself ?

Re: Dell latitude no power on

From what you describe it sounds like you have something shorted on the motherboard or your power supply is bad. Try another known good adapter and if it has the same symptoms then you know the problem is with the laptop. If the computer works then you just have to buy an adapter.
