It's not the PC that is in power saving mode, it's the monitor. The message means that the video card of the PC doesn't send a signal.
So this clearly is a hardware problem. I'd start with installing another videocard. Or maybe I should say "a videocard" if you now have 'integrated graphics' (that's graphics on the motherboard itself).
If you can't do it yourself, you'll have to find either a shop to do it or a friend. And you'll have to buy a new card if it's the solution indeed. You can't do anything about that.
Hello Cnet community,
Since iv owned this pc (Gateway 510x) i have had issues with "power saving mode". Originally my biggest problem was that it would go into power saving mode after a certain time of running without any interaction, and i couldnt "wake up" the pc with the mouse or keyboard. I fixed this by turning off this mode through windows.
Since then iv had problems with starting the pc up after having it shut down for a day or more it would go into power saving mode. The strange thing about this is it only happens if i leave the pc off for an extended amount of time. If its just a quick reboot or if its only off for a few hours it will boot back up problem free. But if its off overnight my moniter will be stuck in this "Power Saving Mode" and i get nothing but a black screen when i start it back up.
At first i could just unplug the video card and unplug/plug in the moniter cable a few times and eventually it would start up as normal. Eventually this no longer worked, but i could use the power switch on the back of the tower to turn off the pc and when i turned the switch back to on and hit the power button on the front it would eventually work.
My latest problem with this none of the aforementioned worked. I messed around with it for a full day and couldnt get the moniter to power up correctly. Finally i turned this little red switch located on the back of the power supply from 115v to 230v and back to 115 while the computer was on and it rebooted itself and the moniter worked as normal and im on it now. My question is what is causing this problem and how can i fix it. Im worried that maybe next time i wont be able to get the computer up and running, and i dont have the money for a new one or even to take it in for repairs. Any help would be much appreciated.
