If this problem has been fixed then please link if possible, I've scoured countless forums and fixes for hours and I've had no luck. Apologies for the long post but I'll cover everything I've tried.
I received an Inspiron 15 5559 from Dell outlet yesterday for my fiance. I spent the afternoon cleaning it up and everything seemed to be fine (for details I installed AVG anti-virus and chrome plus removed a few bits of bloatware, nothing else)
I closed the lid to put it in sleep mode and went to pick her up from work. When we got back about an hour later she opened the machine and it stayed on a blank screen. Nothing on the keyboard, trackpad (or usb mouse) or even the power button would resume the machine. Eventually I had to hold down the power button to hard reset and there was the very obvious noise of hard drives and fans powering down so the laptop was on just not responding.
After checking the power settings and 'what happens when the lid closes' options in power management (set to sleep for all) I then turned to Google. Alot of posts recommended updating drivers which I did for everything (laptop was from outlet but I hope it was a recent install, weren't any updates to be done)
Following another post I went into the device manager and checked the various devices. I've looked at the keyboard and mouse sections as well as the human interface device sections. In all cases any devices that have a power management tab (I checked them all) the option 'Allow this device to wake from sleep mode" is greyed out and unticked.
I opened a command line and started looking at powercfg - after checking compatible devices (HID compliant mouse and keyboard were listed) I entered the following:
powercfg /devicequery wake_armed (to see what devices can wake the laptop)
Result: NONE
So there are no devices able to wake the machine from sleep mode, so i entered:
powercfg /deviceenablewake "HID Compliant Keyboard"
Result: You do not have permission to enable or disable device wake
as the only user on the machine (and administrator) I found this odd until i discovered the hidden top level administrator which i activated using the "net user administrator active:yes" command.
I then logged out and back in as the administrator and went through the same process as before and got exactly the same result - "you do not have permission to enable or disable device wake" How does the secret administrator not have permission exactly???
moving on I've looked through the registry to try and find the devices, I've disabled UAC (and now reactivated it) to check for conflicts there. I've tried using hibernate mode but it seems much the same as shutting it down.
I've also disabled fast startup in the power management and fast boot in the BIOS. I can see no reason nor understand why all devices would be disabled from waking the machine from sleep, sleep is now effectively an endless sleep.
Short of finding this laptops true love kiss I'm at the end of my knowledge/rope. Oh and it's Windows 10 home, I had no choice on the OS (outlet machine) and I'm not upgrading to another OS just so I can use a basic function.
any help greatly appreciated
