Nothing but an amber light on power switch

\015 I was working normally on my Dell Dimension 5000 when we had a local 10 minute power cut. When the power returned the monitor came alive for 2 seconds max then went black. Switch on monitor amber, power switch on PC steady amber. PC will not do anything, just gives me this steady (no blinking) amber light on power switch. Switch clicks normally but stays steady amber. No other led lights to help (don't think the 5000 has them?). Opened the box and motherboard has steady amber light. Monitor, keyboard ok as I've tried them on another PC. Any ideas?\015

Answers :

First thing we want to do is unplug everything except the keyboard, mouse and video card. Next, unplug the power cord from the outlet to the back of the case. Push the power button on the case for 15 seconds to bleed any residual power from the capacitors. Take the CMOS battery out of the motherboard for at least 30 minutes. Replace the cmos battery and plug the power cord in. Push the power button and see if the board lights up and the fans spin. If the fans do not spin then your power supply has failed and you need to replace it. If the fans are spinning and there is no beep from the motherboard indicating a booting issue and the monitor is black and shows no signs of life, then it is very possible that the motherboard has failed.
From Dell: If the power light is steady amber — The computer is receiving
electrical power, but an internal power problem might exist.
Ensure that the microprocessor power cable is securely connected to the
system board.
If the problem persists, contact Dell.

\015\012Four possible work arounds/fixes:
1. Plug the computer into a power strip that has an on/off switch. Turn the power strip on. Press the computer power on button to start as normal, but after after one second turn off the power strip switch just long enough for the fans on the computer to slow down, but the amber computer led doesn't turn off and then turn the power strip switch back on. Computer should start and run fine. Computer typically can be shut down for up to 5 minutes and restarted normally--any longer and you have to use the power strip power switch routine again.

2. Remove the cmos battery for about one minute and then replace. This fix may last for months but problem will return.

3. If either of the above fixes work and computer starts, press the F2 key (usually, could be F12 on some models) when computer screen first comes on and before Windows starts to load. Select the BIOS setup option and reload the default settings --you will have to change any of the settings that chanhged due to upgrades and changes that you have made to the base computer. Note that the a common default BIOS setting includes a floppy drive check even when the computer doesn't have a floppy drive and this setting has to be changed to 'none' typically. This one is not for the faint of heart!
