I have Windows 10 installed and after I leave it for a while, it goes to sleep. A large percentage of the time (though not always) I am not able to wake it.
I've gone through power management and told it NOT to turn off display and NOT to put the computer to sleep.
Still, it does, and can't be woken.
Why is it still sleeping even though I told it never to do so?
The same thing happens to my machine, no matter the sleep settings. It just stops responding and has a black screen after it goes idle for a while. I heard this is a known issue but I haven't seen anything like a solution.
This is most likely a driver issue, actually. Make sure you have installed all windows updates, and all driver updates from your computer/motherboard manufacturer.
I have the most up-to-date drivers available from AMD (for graphics card) and HP. My HP motherboard FOXCONN 2A92 was built for HP by Foxconn and there hasn't been a driver update for that in a long time. :-(
Maybe it's just a lost cause?
If there hasn't been a recent driver update for that model, then you can rest assured that it is the cause. Your computer, in that case, will work best with the last OS it had the drivers for. Obviously you can keep Windows 10, but you may encounter small problems, such as this one. I don't know of any work-arounds. I myself had this very problem with Windows 8.1, but once I upgraded to 10 (with drivers), it went away. That's what I call ironic.
Mine too is an older MB with no driver updates in ages.
The question still remains, though, why it even goes to sleep. It's been told NOT to. So why would Windows ignore that setting? This doesn't seem like a BIOS issue as much as a Windows issue.
Oh, sorry, must have missed that.
Only thing I can think of is your settings in Power Options. Try selecting the High Performanceplan, select its Change plan settings, and click Restore default settings
I'll try that. This is driving me
If that doesn't work, make sure the computer is actually going into sleep, and not doing something else (like crashing, etc.).
No joy on changing to High Performance.
Not sure how to tell what/why I have a black screen with the monitor's showing they are in power saving mode (i.e. the indicator light on the monitor is amber rather than the usual blue). Any suggestions?
