MY COMPUTERS front and back green light is flashing green


you can remove your side cover,and unplug everything from your power supply. then if you plug in your computer and the light still flashes it's your power supply. If not it's something that it is powering. Most likely it's your motherboard. I had this happen to me when there was a power surge/ outage and my computer wasn't even on.

Compaq Presario SR2150NX doesn't turn on. Front panel green light turns on but nothing else happens (no fans, no boot, no noise, nothing) Please advice


On the back of the Power Supply there should be a Green LED, When you power it on if it is flashing, this means that the Power Supply is dead and you need to replace it.

On HP computers, I believe that this means that the power supply or the motherboard is bad. I assume that the outage was due to the thunderstorm and you may have received a surge. In your manual, there should be diagnostic light codes where they will outline the exact meaning. Again, to the best of my knowledge, this means that there is a bad power supply or a motherboard.

Won't come on after power outage


Hi,
Sometimes you have to unplug the monitor from the power supply and wait at least 30 seconds before plugging back in, and make sure you don't need to press the reset button on the power strip.

Green light flashing on the back of the cpu


Your power supply just died. If you don't have a surge protector, the power outage probably sent too much voltage to your computer. A power supply is relatively easy to install, but you do have to have some knowledge to do so.
Try looking at this: http://www.fonerbooks.com/r_power.htm
If you don't understand it, you should be able to get someone to replace it for you for relatively cheap. Also, you can get a new power supply for about $20 on E-bay.
Also, make sure your computer-- and all major appliances-- have a surge protector on them, because this kind of stuff happens ALL THE TIME.

The flashing power switch and power supply LED on the rear in conjunction with a power failure or surge indicates that there is a defective component; typically the power supply, motherboard, memory, processor or modem. -Disconnect all the power supply leads, drives, and motherboard as well as any USB, firewire and other external devices. -Plug in the 115v power supply cable and look at he LED on the back of the power supply. If it is still flashing the power supply is bad and needs to be replaced. -If it isn?t flashing then unplug the power supply plug in one device, plug in the power cord and watch for the flashing LED again. If it?s flashing you?ve found your culprit, if not move on to the next component and repeat the process until you?ve found it. Don?t forget your plug in cards could also be the problem. Good luck and let us know if you have any other questions. As always please don?t forget to rate this posting.
