Had been using my computer yesterday and finished my task, put computer to sleep and returned about 5 hrs later to enter some more info but it would not start. It kept giving me a " returning to power saving mode". Tried several times, turning off and back on but to no avail, same message. When clicking on monitor buttons, it gave me a "no signal from your computer, returning to power saving mode".
It is a Dell Inspiron 560 with Windows Home. It is on a home network and other computers were working fine. Anyone have any ideas?
