    thanks for the information.  I've got about 10 like this here at the school I work at.  I'll have to price new boards.

    Exact same problem. One day after I shut down the machine, it just refused to start back up. When I hit the power button, there is a yellow light there, but nothing at all boots up.

    When I connect the power plug into the computer, a green light turns on, on the motherboard. That means the power supply is working. I took out the RAM and re-inserted it, and still no results. What could be wrong?

    Perhaps the mechanical connections in the power switch is faulty. If so, how would I correct that?

    yellow solid light on front switch and computer will not boot up and monitor is black

  • debsnight Oct 12, 2008

    I have the same problem accept that it is making a high pitched continuous rapid beep noise kind of like if you accidently place something on the keyboard when it is on. (Not sure how else to describe it). I have tried every suggestion I have found to no avail. HP of course wants big bucks to even check it out. If I had the extra bucks I'd get a new one. Any one have any ideas or suggestions, I would really appreciate it.

If you are certain the power supply is good(try it in another machine) and its completely connected it sounds as if your motherboard is going bad, there is a 5-volt supply in your power supply that does not turn off when the system shuts down, its called 5-volt standby, this runs some small circuits on the motherboard that monitor the power switch, when its pressed the circuit starts up the whole power supply. thats how we can power off the system with software. usually its a custom chip and some components, but without the schematics of the motherboard and the replacement parts and the ability to de-solder and solder on a multi layer board its not usually repairable by the end user.

the system memory and processor are not even used in this part of the system startup, they come into play after the supply is up and stable and supplies the power good line to the motherboard.

make sure the supply is good, and all connections are making contact, that none of the pins have backed out of their housings when being plugged in and that there are no cracks in the solder joints where the power connectors attach to the motherboard.

Hp D4000 won't boot up. Power supply light is on solid green but its almost as if the power button on the tower is not turning the tower on.


Computer does not boot up The problem maybe the RAM, it is faulty or just needs reseating to make proper electrical contact.
Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.

I have a Dell Dimension E521. When I cut the power on everything comes on including the monitor, but the monitor will stay black. It does say something about power save hit any button but the screen


A solid green light means the computer is operating normally.

A solid yellow light indicates the power supply is operating normally but the computer is not processing data.

This could mean there is a problem with the CPu or another component on the motherboard.


((A blinking yellow light indicates the power supply is receiving power from the wall, but not functioning properly.
This generally means the power supply itself is bad and should be tested or replaced.))


A blinking green light means the computer is in standby mode.

You should consider visiting Dell Support and downloading the manual for your

your Dell computer. So use the LED power light codes if your Dell computer has them.

hope this helps

My dell inspiron 1525 power light is blinking amber???


Most newer models of Dell computers now have a diagnostic LED surrounding the power button on the from of the computer. When you press the power button to boot the PC, the light should be green and remain green under normal circumstances. Any other lights will help you troubleshoot the power issue you are having.

So use the LED power light codes if your Dell computer has them. Also pay attention to any unusual beeps or sounds coming from the computer. Then join us in our free computer tech support forums and we'll try and help you solve your PC problem. Sometimes, however, a service call to Dell will be required. If your system is still under warranty, you should always just call them first, as tampering with your computer may void your warranty.

Hope this helps!

So use the LED power light codes if your Dell computer has them. Also pay attention to any unusual beeps or sounds coming from the computer. Well, I was sure that the voltage selection switch was in the right place. And I found it highly unlikely that the processor power cable would suddenly unseat itself. Ugh.
Then I had an idea. I flipped off the surge protector and then flipped it back on. Tada! No more orange lights. Weird. The moral of the story: try the simple stuff first.

I hope this helps and please dont forget to rate my answer. Thank you! :D

Screen will not come on hard drive light no light checked power supply is ok


Things to check:
  1. Power led on the front of the tower, it should be solid green when on. Flashing Amber is generally an indication of a bad power supply inside the tower
  2. Power LED Solid AMBER indicates system is not finishing the power on self test (POST) and you remove all connections from the tower except power and try turning on again. If no change, remove all PCI and PCI-E cards from system, try again, no change replace motherboard.
  3. On the back of the tower are 4 diagnostic LEDs near the ps2 ports marked ABCD, after the POST, during a normal boot the will flash in several sequences and with boot is finished all 4 should be green. If they stop an a different pattern, then that indicates a failure Yellow Yellow Green Green indicate bad RAM for example
  4. If the LEDs on front and back are Green then the system appears to be booting but the monitor display is not functional

When comp pluged in just a green flashing light


If you are sure that the 110 volt power is coming into the computer then the most likely problem is that th epower supply died. Obtain a new one of the same or larger wattagge as the one you are replacing . It does nto have to come from the manufacture of the computer.
