My HP computer is stuck in power save mode. I have tried all the obvious solutions but nothing works. I also called HP support but it would cost almost $100 for them to fix remotely. Not an option eit

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.

First you need to make sure that there are no other removable devices plug on the system, like usb, external hard drives, then if that will work try to go to the bios, press f2 when you see the dell logo, and go to the system setup, go to the boot device configuration and make sure that removable device is not the first boot device, if it is the first one choose hard disk and then second boot device ad cd rom/dvd rom and then disable the 3rd boot and the fourth boot device. Make sure to save the changes. And restart the system again. Once the computer is back and running try to go to support.dell.com and check the bios, download if there is a bios update for the system.

i) usually an computer enter's into power saving mode if computer monitor is not receiving any singals from the computer tower, so it has nothing do withur computer monitor(computer monitor is working fine), there is some problem withur computer tower.

ii) now try  removing all the physical connections going to computer tower(back side), wall socket  and replace them ....., (to avoid loose connections) 

   now see whether ur computer is turning on and working properly so that your computer monitor receive singals ....

  let me know what is happening

Thanking you
