Since upgrading to Windows 10 I am having a problem waking my Inspiron from sleep.
If I leave the lid up and the laptop goes to sleep on battery or when plugged in it will not wake up
If I put the laptop to sleep using the on off button it will not wake up
If I close the lid whilst plugged in before laptop goes to sleep, and then remove the power supply it will not wake up
If I close the lid whilst on battery before laptop goes to sleep it will wake up, or maybe it doesn't sleep as the battery seems to go flat quickly?
If I close the lid when plugged in before laptop goes to sleep it will wake up, or maybe it doesn't sleep
When it won't wake up the only way is to restart by holding the power button down for 7 seconds and then restarting, this is really annoying.
I have installed all the latest updates from Dell and Intel.
Any help very much appreciated
I'm having the same problem you've described .... I have disabled all startup apps and everything works fine .... add them all back and things work as they should, until I use the machine for a few hours and then the problem returns ... I've updated all drivers and same problem.
I've rinsed and repeated everything in previous paragraph with exact same results. What seems interesting is that if I hibernate, the screen blanks, but the CPU fan continues and the keyboard backlight is still on. As you have done I press the power button until the keyboard back-light goes off ... and when I press power button again, it boots up and the apps are running .. just like if hibernate actually was accomplished.
It seems the hibernate function is executed, but but the laptop power is never turned off.
I have the same problem with my Dell 7347 after update to Windows 10. I've tried to reinstall drivers but it doesn't help.
I have also noticed many critical errors in event log:
"The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."
I am having the identical problems described by the posters to this entry. Keyboard remains illuminated after the computer enters sleep mode, then the computer will not wake. Must reboot. Also, sometimes it will not resume from hibernate properly.Usually a short press on the power button will get things started, but sometimes in hibernation mode, I have to hold the button in for many seconds before the system responds. Sometimes the response is a proper recovery from hibernation - other times it is a full reboot.
Also, since switching to Windows 10, boot times seem much longer. I like Windows 10, but I will be glad when these issues are fixed.
