Lenovo desktop pc is stuck in power saving mode. Monitor comes up with “Lenovo” and then a thin yellow square with “Power Saving Mode” comes up and just lasts just a second, then the monitor goes out. I have tried everything, shake the mouse, hit the enter key, the F5 key and all other keys also. Please help !

Try tapping F8 continously as soon as you start the computer. Choose to start in safe mode and then go to Control Panel to check power settings.
If that doesn’t work then borrow another monitor to test with.
How about providing some background information. When and how did this start happening?
