Post by a***@gmail.comI have an older Dell Latitude D620 laptop. It went dark in the middle of me using it. When I press the power button, the power lioght flashes. That's it.
Could anyone provide advice as to where to start diagnosing it?
Thanks in advance.
"Flashing" is a complicated word. What does "flash" mean? The old
self-test of the IBM PC (called POST = Power On Self Test) made
beep-tones on the speaker. The were acoustical "flashes", willfully made
to give signals. But is there something like that for the POWER-light?
Think of something totally different: power is switched on, voltage
builds up - bang, a short-circuit drains the current to such a high
level that the power-supply shuts down. Power is down, so it starts
again, voltage buils up - bang... This I guess to be the most common
cause for the flashing. The question is: where the hell is the
short-circuit? OR is it really a short-circuit? Might as well be a
problem with the power-supply, which does not deliver enough current
anymore and breaks down.
What I would do:
1. take off the battery
Try.
2. test with another power-supply.
3. Depending on how much "rest-value" the dead computer has: take a
screw-driver and have a look inside the computer.
