I was working on my Dell Latitude e5540 and suddenly it turned off. The ac adapter and battery were in.
Now it won't turn on.
The lights on the ac adapter (original) are off. If I plug the adapter to the wall the adapter lights turn on, but when I plug it into the laptop the adapter lights turn off immediately. Of course the laptop still turned off.
Same thing happens when I remove the battery, the ac adapter lights will turn off.
The laptop won't turn on with just the battery in neither.
So the battery is OK and the adapter is OK.. (I have no other battery or adapter to check with).
So the motherboard is necessarily finished?
Thanks
