Laptop gets unresponsive when getting asleep

[oliverm91]

Whenever I close my laptop or leave it a few minutes it should sleep, but it just turn off the screen.
The led lights (for battery, HDD wich I replaced for an SSD 2 days ago, wireless connection and something else) are still on. Also the fan of the laptop still makes noise. The problem is that if I move the mouse or press any key It doesn't do anything (or at least doesn't turn on the screen) so I have to turn it off the bad way (keeping pressed down the power key).

Interesting fact: if I press fn + f5 wich is the turn-off-screen combination, the screen turns off and immediatly turns on again, in less then half a second.
Interesting fact 2: If I sleep the laptop with the option in the power button while logged in then the problem occurs, but if I do it logged of it works just fine.

Background: Problem occurs after I installed a new storage drive (SSD) and installed Windows 8.1
OS: Windows 8.1 x64
Laptop: Acer Aspire V5-561G (Intel i7-4500U, 8GB RAM DDR3L, AMD R7 M265 2GB, 500GB SSD Samsung EVO)

PD: This is my second thread about this because the first one got no replies.

Hope you can help me.

I had this problem in windows 10. First try and change the settings to sleep when the lid is closed. If this doesn't work, try changing the option to hibernate and see if it works.
