Hello everybody! I got one really irritating problem with my PC. It can't "Wake up" once it had entered in sleep mode. Actually, the PC turns on but the monitor is still black and only shows the message "Power save mode". I need to restart the PC in order to use it again. Sometimes the PC even enters in Sleep Mode by itself. Do you have any ideas for what could be causing this? I suppose it is the power supply to blame but who knows it could be the system, too. I'd be really thankful if someone help me to figure it out.
My PC Can't "Wake up" After Entering Sleep Mode

One thing you could try is removing all power from the machine (Switch off at the wall) then press and hold your Power button for about 30 seconds. Release, and try again with power restored. Next you could try resetting CMOS by removing the CMOS battery for 30 secs, but that involves entering your Tower, and if it's sealed it may void your Warranty
Let me know, if its done

Well, I said that everything's alright but unfortunately it's not. My brother've entered in Sleep Mode and has left it for about an hour or two. When I came to exit form the Sleep Mode it did the same - just black screen showing "Power Save Mode". I've noticed that it can't "Wake up" only if it has been in Sleep Mode for a long time.

Hi, have you tried "Unplugging the power and pressing the start button for 30 seconds! prior going to CMOS.
I tried the first one - to unplug the power and then hold the button and it worked the first time. But as I said I've noticed that it can't "Wake up" only if it's been left in this mode for a long time. If I put it in Sleep Mode and then turn it on immediately there's no problems. But, you know, It's useless. When I need Sleep Mode, I need it for a long time.
