After updating to Windows 8.1 my system does not sleep or hibernate anymore. I can shut it down or restart it but if I try closing the laptop so it does to sleep/hibernate mood then it does not turn off. Once I open the laptop it is still on and the screen is black and won´t turn on. Only thing I can do is Force a Shut Down by pressing the power button for couple seconds.
It started when I updated to Winows 8.1 which I updated though my computer. (Windows App Store)
What have I done to try fix it:
-Tried updating my graphic drivers which are up to date. - Uninstalled any program that was not being used and was useless ( Advertisement, spam, auto downloaded programs ) - Rebooted Computer. - PC Checkup from My Dell program. ( all results came back good ) - Malware/Anti-virus scans ( They were both fine )
- Intel(R) Core(TM) i7-4500U CPU @ 1.80GHz - RAM 8gb - Windows 8.1 (64bit) - Touch Screen - Laptop Type Dell Inspiron 5537 - BIOS A06
- Intel(R) HD Graphics Family - Generic PnP Monitor
- AMD Radeon HD 8800M Series
I just went back to check the Advanced Settings in the Power Profiles. Found three settings that were not set right.
1 - Under Wireless, change power savings mode to maximum performance
2 - Under Multimedia, set when sharing media to allow the computer to sleep.
3 - Under Sleep, set allow wake timers to disable.
My I660 will now go beddie-bye all by its self. Perhaps one of the updates changed these, possibly Win 8.1 itself, and I never bothered to check - my bad.
The only setting I had to change was the multiedia one.
Now when I manually make the computer sleep it actually goes to sleep mode.
The problem now is that it does not reactivate. I still have to shut it down and turn it back on.
Last night Sleep mode not working in Windows 8. The problem is, when I closed the laptop lid the display off but the computer doesn't Sleep. Solved: Sleep Mode Not Working In Windows 8 And 8.1
My Dell 15r SE 7520 did the same thing when I updated. (Worst mistake I made). I went to the Dell site and updated all of my drivers and BIOS to the ones for Windows 8.1. The device manager did not show any problems, but after I did this it fixed a "thread stuck in device driver" problem and the hibernate problem.
