Folks, I have tried two or three times to reload Win8.1 by either formatting the previous install or on a new drive. It has never fixed my sleep issue. Be aware that you may still be destined to fail.
kenJ said:I was able to get mine to sleep after a new, clean install using the 8.1 ISO.
However, I do want to report that Lenovo did issue new 8.1 drivers for my K430's LAN and wireless Realtek PCIe GBE and RTL8166 adapters. FWIW, I think I did try them with my 8 to 8.1 to my 8.1.1 upgrades but installing them didn't solve my problem.
Hopefully, others will report if new installs work. Also, maybe others will be able to get new 8.1 drivers.
UPDATE: Maybe this might help others....
After 16 days of sleeping OK, my machine stopped sleeping. However, I made an image each day and noted the changes that I made. I went back to an image I made 2 days before the problem date. It worked about a day and then stopped sleeping but would sleep when I removed the network cable.
OK... now let me think..
I know I didn't have a task problem because I completely killed the task scheduler from running.
Not Metro sync, as I had turned that off to see if that caused any problems.
I believe the computer might be trying to phone home to send out some alien message. So what to do?
Well, I looked at the event log and found it thru an event error "APPCRASH UMonit64.exe StackHash_5861" earlier that night when it stopped sleeping. What I didn't remember was that I played some music with media player for the first time after doing a clean install. I rebooted and it slept again until the next day when I played music and it stopped sleeping. But then, I was monitoring my every move. Trying what I did the day before, watching for errors and watching for no sleep. At that point --- no sleep --- "event error" logged.
Well, I had remembered to "Turn off customer experience reporting to MS" but I had left it in "automatically check for errors". I then changed it to "ask me if I want to report errors". I rebooted and hit media player but this time when I had an APP crash it alerted me and I told it "DON'T PHONE HOME". Once I did that, it continued to sleep.
Well, I then created a custom event view that just displayed critical warning for only the past 24 hours and I started fixing several problems. I fixed my APP crash by uninstalling Genesys USB Mass storage Device via the control panel. I removed it and my Media Player works without an error now.
Bottom line is (1) don't let it phone home without your approval and (2) fix any critical warnings in your event log.
Maybe when it is phoning home with 8.1, nobody's there and it keeps calling.. and calling.... Or maybe a crash stops the internal sleep timer from running. It never times out, so it never sleeps???
I am monitoring to make sure this is the fix for me. I hope as I went 16 days without any problems and don't look forward to more troubleshooting.
