Dimension E521 stuck in power saver mode

I would say it is in the Hibernation Mode To get it out of this mode you need to go to your Control Panel, open "POWER OPTION'S" and deselect the Hibernation mode then reboot.

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

Try Hitting the Power Button. Some systems require you to hit the power button to bring it out of Power Save, Sleep or Hibernation.

Press and hold the power button for 5 seconds this will turn the system completely off wait 5 seconds then turn it back on as soon as it boots up go into power options in the control panel and click the option from power saver mode to do nothing as there is a fault with some computers that it gets stuck in power saver mode

The 123 lights on tower translates as:

Routine system activity subsequent to video initialization.
Watch your monitor for on-screen messages.

Disconnect the video cable from the computer and see if you get floating color bars on display. If not, your monitor is defective.

Narrow it down to a monitor issue (and fix or replace the monitor in particular) or a PC issue (in which case we're also low on info. about the issue.)

Probably corrupted some importand windows system files.
Boot in safe mode, and do a system restore.

Start, Accesories, System Tools, System Restore..
Choose a restore date. The last one in there will likely do it.
Allow it to do it's thing.. Should be all good. Cross your fingers..

hi !
If your have already changed the power supply, there is still a lot of main points of failure in the no power situation. If the motherboard has a flea light, then it could be one of the components. It can be the memory(if no beeps are heard, then memory is not the cause), it can be the processor, or it can be the control panel, in which the power button is attached. Try to check the cables as well.
Cheers !

Try tapping the F8 key while booting the computer, you will get the start up menu, choose safe mode, when you log on, go to the display settings, that is right click on the desktop, properties, screen saver, advanced and make sure that hibernation is off, along with turn off disks or whatever , probably see turn off monitor after XX minutes, I make ours 15 minutes (150 computers and servers), I don't let the disks turn off. Choose always on also, not home/office. Try this and see if these settings help.
