I have a Dell Precision M90 laptop that is not starting up.
It makes a clicking sound and a couple of lights flash briefly under the display when I hit the power button. After that, nothing happens. There are no sounds or anything else showing signs of life.
My first thought was that it was a dead battery. This is what I have tried so far with no difference:
- Two different power supplies.
- Removing the battery and trying to start it with just the power supplies.
Does this rule out the possibility that it is just a dead battery, or do these computers need a battery to start even if they are hooked up to a power supply?
If it rules out the battery, what should my next trouble-shooting step be?
