If the green light you're mentioning came from the power supply, you need to replace it. green light flashes from the LED at the back of the power supple serves as an indicator if you have a good or a faulty power supply.

I think there is a need of dusting the RAM and DIMM socket. Do the following steps:-
1. Open the cabinet
2. remove the RAM
3. Clean the DIMM socket(RAM socket)
4. Place the RAM again
5. Power on your computer.

Bad Power Supply. Weak voltage power rail.

The Green LED flashing on the back is now a diagnostic light, and is conveying the above.

Allow me to show you using HP as an example,

Green power supply light blinking, computer won't start.


A lot of those E-Machines used a small power supply (150 to 180 watts) and were known to have a failure rate. There is a way to check them by jumping across a two connector wires on the end that plugs into the Motherboard. Let me know if you want try this.

I have an HP Pavilion a384x. It will not turn on


First with the computer turned off make sure the switch on the power supply is set to 115v.

If you turn the computer back on and you still get a flashing green light on the back of the power supply and a constant light on the front of the computer with no video, then try replacing the power supply with either a new one or a known working good one.

If that doesn't do it then it has to be the motherboard at that point.

Keep in mind normally on those power supplies, the green light should be constant. So it has to be either the power supply is bad or the moterboard is bad and you'll know when you put a new or known good working power supply in the computer.

Green light flashing on back of unit near power cord also green light flashing on motherboard near power supply plug in.


I would suggest trying to replace the power supply. If that does not fix the issue, i would need to hear more about the computer.

HP 2550 will not print. Green light flashes. I'm


If the machine is making "working noises" while it flashes, it is most likely calibrating. A good way to find out if the problem is due to connectivity issues with your computer is to turn the machine off, unplug for 1 minute, plug back in and turn on. Wait until the light is solid, indicating its ready to go, and then press and hold the green button until the lights flash. It should produce a demo print for you. If it doesnt, the problem may be with the printer, not the computer. Also, check in the "Printers and Faxes" settings in the control panel (if you are running windows) to see that the 2550 is set as the default printer.

AL 1916 Monitor Green Light Flashes


I think you have loose cabling somewhere. Try to unplug (and untangle) the video cables and then plug them all back together firmly. If this does not work and you know your machine is booting up properly, you might have damaged the monitor somehow accidentally.
