how to overcome Lenovo Power Saving Mode SNAFU

Thanks Fingers, Derek & Jeff,

I had a very similar problem with our new Lenovo ThinkCentre M83. Left the computer and monitor on, and went home for dinner. Came back an hour later to a black screen. The computer was in apparent sleep mode. Had to keep pushing screen buttons, and eventually got the small transient floating blue banner "Power Saving Mode" and then black again. I kept trying to turn off the computer without luck (not knowing that the button needs a 6-second hold down). I checked all the cables, etc. If not for your post I wouldn't have known what to do. Interestingly, after shutting down and rebooting, the computer went into Safe Mode, and then after starting normally after that, the Monitor kept cycling through blank coloured screens: red; green; blue; white; black. I had to reboot again to get past that. I've now set my power-off to NEVER and hope that I Never have to deal with THAT programmer's lunacy ever again ! Aren

You mentioned monitor buttons but which keyboard keys did you try? Usually if you bump any key or move the mouse, the system will come out of sleep mode. From the ThinkCentre M83 manual:

"To awaken your computer from a Sleep or Standby mode, press any key on your keyboard."

I moved the mouse, I clicked the mouse, I almost killed the mouse. I also pressed lots of keys on the keyboard including many attempts at Alt Ctrl Del. All to no avail. The computer wasn't just sleeping or hibernating - it was comatose !

And the psychedelic cycling colour show on the monitor was out of this world. I thought that was never going to stop. But luckily I was able to kill the machine that time by pressing the Start button.

Perhaps some angry management could help you more... ;-)

I have noticed that some machines (not all) have a problem in exiting sleep mode. These are typically desktop machines so that would be mainly hybrid sleep where the contents are both held reserved in RAM and copied to the hard drive as a dual protection to be able to wake correctly. I have also found that setting the hard drive to NEVER power down appears to fix this. I have theorized that if the hard drive enters into power saving mode before or at the same time as the machine goes into sleep mode than since it cannot copy RAM onto the hard drive in the time allocated then it hangs partly into sleep without the copy on the hard drive to reload. In all cases that I have tried and recommended to be tried, this appears to fix the issue and you can safely use hybrid sleep again. Note that during sleep the hard drive is powered down so it is not necessary for the hard drive to power down by itself to save energy and wear. I have had machines work properly with sleep for 10 years after this fix is applied so it is worth trying for you as well.

You have to be a little bit crazy to keep you from going insane.
