Acer Aspire E1-572G won't wake up from sleep

I have this laptop at work, Acer Aspire E1-572G, and whenever it sleeps, it does not want to wake up whatever I do. I put it to sleep by closing the lid or FN + ALT + F4.

I tried of course opening the lid, and using the same key combination again, pushing the power button, moving the mouse. Nothing helped! Any ideas?

PS: In the power plan I currently use, the hybrid sleep is off.

Update: It has Windows 8.1 Version 6.3 (Build 9600) and it is brand new.

Solution 1:

I have the same laptop and the same problem after upgrading to windows 8.1

After hours of testing things out, using different versions of drivers, it still didn't fix the problem. The only solution that worked out for me is disabling the Windows 8.1 Fast boot. It didn't affect my boot time that much anyway. Besides I encountered a lot of errors after installing software if I use the "shut down" option. Since restart isn't affected by the Windows 8.1 fast boot. I had to "restart" all the time if I install a software to be safe. So, I just disabled the "fast boot".

Now it goes to sleep and wakes up normally.

Solution 2:
