Lenovo desktop stuck in power save mode how do I get it out?

Specs: Windows 7
My mother has a Lenovo and it suddenly went inot power save mode. I appreciate all the ways to solve it that have been offered, but her screen is black. She can't go in and change things because she can't see it. It is a desktop I'm afraid I have no more information. I am somewhat Non-computerized, so easy explanations will help.

A google trawl seems to suggest this may be a problem more with the monitor (external) than the desktop system itself.

Presumably the Leonovo is powered down when not in use... However is there still volts going into the system even though it is "off" as at the front; i.e is the mains cable still plugged into a wall socket and that socket is live.

A very long shot: totally remove the power cord from the mains outlet; and wait a minute or three. Then restore full power to the Lenovo and see what happens as/when it powers up.

Does the Lenovo boot up OK; as in she can hear the normal sounds and see one or two flashing lights - on the computer itself as it boots up (and possibly can hear the fans running afterwards?

Any beeping sounds when it boots up?

Presuming it is the monitor that is going into sleep mode - which is very likely the situation.. have a read of this olde post as it discusses the where/wherefore of that...

If there is a chance of testing the system with another known to be OK/working monitor that would b e a useful test too.

Not so sure this is much to do with Power Save Mode. Seems it is just not starting up.

As given, first step is to beg or borrow a monitor just to make sure it really is the computer at fault.

We need to know just how dead it is and whether you ever see anything at all on the screen.

When you try that "long shot" while the power plug is removed hold the Power Off/On button in for
at least 20 seconds then press it a few times before restoring power. That will discharge the motherboard components which can sometimes "unstick" things.

It could be, for example, that the power unit has failed but it is early days to suggest that on the information given.

Always pop back and let us know the outcome - thanks

Sorry, I guess my answer only goes to the person. who wrote the message. When she turns the computer on, the screen gets the Lenovo logo and a piece of white for a second or two on either side, then it goes black. I have to try the powercord thing, it is difficult as she cannot do things like this herself since she is 82. I will go over tomorrow and see what I can do. I appreciate the advice.

It might be worth seeing what happens in Safe Mode. Tap F8 while it is booting up and select it from the list. It might at least take you to the settings.

Always pop back and let us know the outcome - thanks

It does suggest that the monitoritselfis OK, based on the brief video signal you see, before the "power save" message appears.

It might be something as simple as the graphics card being loose... or even RAM requiring reseating...

Try - with all power removed, mains cord disconnected from the wall outlet - removing and re-inserting the video card. Perhaps also clean its edge connecter with a soft pencil type eraser. Wipe edge contacts with a soft linttless cloth (maybe a kleenex tissue). Then re-install the card, and then remove and re-install it a second time.

Also remove RAM sticks one at a time and repeat the cleanng process for each stick, as for the video card above. Then re-insert each stick into its RAM socket, and then remove and re-insert a second time. When all sticks have been cleaned that way, re-apply power and see if the problem has been resolved?

Also, if you have a spare (knownto be good) cable to connect the monitor to the desktop, try using that as a test (to elminate the original cable from the equation...) It's not likely the cable is at fault here, as there is a display briefly. However it'swise to check all possibilities...
