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

Monitor won't come back from "sleep" setting.


Yes it can be, try it on other PC first to narrow down the problem.
Most problems in the Dell are failed transistors, poor solder works, see pictures here for guide: http://s807.photobucket.com/home/budm/allalbums

Dell GX280 Optiplex wont start


Dell GX280 has been known to have issues with mother board because of bad capacitors that were sent out in them at that time. I have had so many issues with them when i working as an it. If you can open up your pc and look on mother board for expanded capacitors or even leaking. if they are not round it means that is the problem. Dells are very easy to open. On top and bottom there are kinda buttons u can press and just open towards the side that has lock for like locker lock and look inside.

Dark display about 1h. when swicth on.help me pls.........


I'm going through the same thing with a Dell 1905FP - it has 3 bulging capacitors on the Power Supply/Inverter board, and I suspect they are the culprits. At first it delayed a few seconds to start (green power light flashing in all situation), then it took about 10 minutes, then delayed about 45 minutes, then went all the way to about 6 hours - all within a week. When it did come up after the delay, it was perfect. Now it won't come up at all....

It's out of warranty, Dell will have nothing to do with replacing this common failing board, and the replacement board is $50 from an online LCD repair shop.

I'm trying the capacitor replacement tomorrow - they're about 25 cents each... it's worth a try.

Montior wont turn on


Solid Amber Power LED is indicative of a Motherboard failure. Replace the motherboard.

The GX280 is one of many motherboards made during that time period that may have had capacitors that could fail due to a manufacturing defect if the capacitor. Check the capacitors on the motherboard to see if the tops are popped (there is a X engraved across the top of each capacitor, it the X is open, then the capacitor is bad.)

Flashing green power light - Black screen


I had the same problem with an AOPEN 17' lcd that was left behind at a rental property... I plugged it into my dell dimmension 4400 in place of my old analog. It worked fine the fist night, and got up and when turned it on again it had the famed green blinking power light. I switched back to the analog, and just disappointed I plugged in the AOPEN to another power source, and power came on a steady red light. I plugged it back into the puta and it came on again. I have not turned the monitor off again for fear of the blinks, and has been working great for close to a week now. Hope it helps someone else out there. Richard
