When i turn on it goes start to pc entering power saving mode


Are you sure it isn't the monitor entering powersave mode?
An unhooked monitor (especially flatscreen DELLs ) will go into powersave mode if it isn't getting a signal but is getting power.

First unplug and then replug your monitor. Both ends of the cord, the end in the back of the monitor (if it comes out at all) and the end that plugs into the computer.(unplug it from the wall first)

Reboot computer.

If that fails...(and you do have a video card)

Unplug everything from the computer, open the box, ground yourself by touching the metal frame of the computer case and reseat your video card....you may have to undo one screw to get it out.
DON'T drop the screw into the case!

Put it all back together and try again.

If that all fails Boot Windows (windows right?) into safe mode and change the power settings for the monitor...perhaps something got changed or broken by an update.

If that fails....

Get Linux.

Have hp pavilion a340n that won't start, screen says "WARNING" PC entering power saving mode and then goes blank. the computer never boots up.


hi mylesj880,

Press del. or f8 to boot to Bios there should be an option for you to remove power saving mode. If none then you probably need to update the bios be careful when updating bioses.

Hope it helps. Feel free to ask
Thx

Monitor goes into power saving mode when turned on. Doesn't go on when mouse is moved.


It's not on power saving mode, it does not sense that it's already is plugged at your VGA.
The only thing to test it out is to have another monitor/computer *to see which one is not working
But I'm pretty sure that it's a computer problem, Probably a VGA driver problem or a motherboard.
The best way to trace is to have another monitor/computer.
