laptop power problem

Do you have a question? Post it now! No Registration Necessary.  Now with pictures!

Threaded View
I 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.

Try pulling out the RAM sticks and putting them back in again,  
making sure they are firmly back in place.

If it is/was emitting a funny smell, it could be that a bad  
capacitor leaked inside and will need to be replaced.

Have you removed the battery and tried running it with just the AC adapter?

"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


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.

    It's either a really fast guy in a red suit or one of those
girls at Mardi Gras trying to collect beads.

    PC's used to "flash" the num lock and scroll lock LEDs.  Now a days
most laptops flash that little line of LEDs at the top of the keyboard in
various patterns to keep you amused while they boot.

    There ya go!  Just like at Mardi Gras!  Hey, nice connectors.
