Question about Dell C600 (002UH) Motherboard
I am guessing this issue is similar to something I noticed only recently when tampering with an old C600. The LED is the power on LED and with it is the HDD LED. They stay on for a few seconds then nothing. I believe the laptop has had the Fn+Esc keys simultaneously pressed and the Laptop is now suspended. I dont know how to fix it and no matter what I do the laptop will not power up. I have been told that it may be useful to remove the battery for a while and let the charge storage devices dissipate so resetting the BIOS or better still get the BIOS battery out which resets the BIOS to a default mode. Haven't tried it yet though, however the motherboard and BIOS is encased in riveted steel Faraday cage! Brilliant!

Hi Jack, When you say green light are you referring to the battery led? If yes it might be your A/C adaptor causing the problem. I've had laptops flash the battery like it was going to charge then stop. If the A/C isn't supplying power and the battery is dead you could see your symptoms. If its not the A/C adaptor more information would help a diagnosis. What were the circumstances that lead to this, exactly what lead died and so on. Let us know if we can help further and don't forget to rate the posting.

A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,
if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.
To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.
Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.
Press the power button if the screen remains black.
Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.
Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.
Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.
Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.
Slide the battery latch to eject the battery. Pull the battery out of its compartment.
Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.
Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.
Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.
Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.
Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.
If the external monitor works, the LCD screen could be broken.
If the monitor doesn't work, the motherboard or video card might need to be replaced.
Hope this helps

Test the PSU if the units fan is not working the power
supply unit is faulty
if you are having trouble with your graphics card
One bad lead can cause a computer to continue on a cycle or
to shutdown or fail to detect your hard drive
Test all leads that attach to your hard drive including
electrical extensions IDE,SATA
the leads from your
"((motherboard to your hard drive))"
make sure they have a secure connection and are not faulty or just
replace them there probably old and faulty
make sure all leads that are attached to your drives dvd\cd
have secure connections and are not faulty even the
electrical extensions or just replace them they could be faulty a computer
needs its connections to continue its cycle and have an end so any faulty leads
will end up with a computer error If your computer came with a motherboard disc
the drivers could be on it or you might have a dirty graphics card remove the
graphics card and clean the socket hope this helps
