Green light on my power supply stays lit after unplugging


Usually the light will time out after the capacitor has drained. Your machine is getting a bit old , your PSU may be the problem. If you plug it in and push the on/off button and it blinks, fans spin and shuts down, it's most likely the PSU. Look for a in-line fuse on the Motherboard, if blown, replace. Look at the motherboard closely for damaged components, capacitors, etc.

Green power light comes on goes off then on again stays solid, moniter says no signal, mouse lights up, and three red lights on key board flash then nothing why?


If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

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

I am trying to hook up to my new comp. and new internet and the lights come on for the wireless, wired and router r green then the modem light is red, what am i doing wrong


There is nothing wrong with your modem. There are modems that when you turn it on, the wireless, dsl lights are green while the power light is red then after a few seconds, the green lights disappear and the red light will turn green. After sometime green light will come back on. This means your modem is restarting and doing a self check.
If the power light stays red, then you a have a problem with your modem.

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.

No video


Try to check the light on the monitor. If it is amber, then check the video cable both from the back of the monitor and the tower. Try a known-good monitor. Check the diagnostic LEDS of the tower. There are four of them in the front panel. When the computer starts normally, the lights flash. After the computer starts, all four lights display solid green. If the computer malfunctions, the color and sequence of the lights identify the problem. If you have a solid green light on the tower, no beeps heard and no video, check the LEDS. If you get 2-4 light, a possible graphics card failure has occurred. If the computer has an external graphics card, open the tower, remove the card and put it back in. If still persist, try a known-good card. If it still does not resolve the problem, try reseating the memory cards. Remove and put it back in. If still no go. Then it's a motherboard problem.
