Solved What is waking my computer after precisely 3 hours?

I can't seem to trace this down. At night I simply close the lid of the laptop so that it goes to sleep. The system logs show that the computer wakes itself up out of standby precisely 3 hours after it went to sleep. Often it remains awake, completely draining the battery, while sometimes it does fall back to sleep after a couple minutes due to inactivity. However, it will continue to wake itself up every 3 hours.

When I check the system logs in the Event Viewer I see that the wake source is unknown. Another commonality every wake cycle is the log entry for the Intel Management Engine Interface, where it reports that the "Intel(R) Management Engine Interface driver has started successfully." Not sure if this driver is to blame, but that's the only thing I have.

I have also disabled the network interface's ability to wake the PC from standby.

Right-click on the Start button and select "Power Options".

"Change when the computer sleeps" > "Change advanced power settings"

"Sleep" > "Hibernate after"

Dude, where have you been all my life? Wow. That was easy. It was set to 180 min., which is exactly 3 hours. Thanks! I haven't really tested it, but as there are no wake locks and no devices able wake the PC, I can only imagine that this solves it.

Now I have to wait 2 more hours to see if you follow up.

Confirmed. No longer does it wake up after 3 hours overnight.

That is really odd. Typically hibernate is used only for notebooks (so when you close the lid, it opens back up with everything still the same). So being a PC, it is odd that was set at all.

It seems what was happening is the computer went into normal sleep (or hybrid - which is great for PCs) after a normal period of time. And then at 3 hours because hibernation uses a different type image file, it woke itself up to put itself back to sleep!?!? :think: :huh:

Sounds like it was coded by The Three Stooges: "Wake up and go to sleep!" :)

"Wake up and go to sleep!"
lol!

Anyone who has spent any time in the military is familiar with a similar "command", "Hurry up and wait!"

Hmm, now that I think of it I could use a nap. Please wake me up in three hours. :)

It is a laptop. And, I can't believe I didn't remember that I had set that 3 hour hibernate function intentionally from the beginning. I was attempting to emulate Intel's Rapid Start Tech (IRST) with which the new laptop isn't equipped, unlike my previous Yoga.

So, essentially I wanted to the laptop to enter into normal standby upon closing the lid, and all joking aside, have it wake itself up after 3 hours to put it to sleep for good (hibernate). This is exactly how the Yoga with its IRST had done it. I think it brings the best of both worlds to the table by preventing unnecessary writes to the SSD between short standby stints but yet preserves battery overnight between longer sessions. But, for whatever reason, it either stayed awake or returned to normal standby.

Hmmm, I guess I should have read your opening post again. Don't know how I got this was a PC. You make it clear it's a notebook.

Anyway, your notebook should be smart enough so if you just close the lid, it will go to sleep. If the charger is connected, it will stay in that mode (with the USB ports still alive so you can charge a cell phone, or wake the computer by wiggling the mouse or pressing a mouse button). But if the charger is disconnected, before the battery runs down, the notebook should then save a hibernation image so you can continue where you left off next time you plug in and fire it up.

I registered on this forum just to say thanks, this has been bugging me for such a long time!

I turned off the auto-hibernation and was delighted to find my laptop had not turned on not only while I was asleep, but also while I went to work.
