So Windows forced me to update to Windows 8.1, which I didn't want but still. They don't care, they forced the update. Which means my laptop reboots way slower, but I'll deal with that. Perhaps W8.1 is better at several area's. Anyways, I got a problem with sleep and hibernate mode. I can enter them, but when I try to exit it Windows doesn't continues but it reboots, losing everything ongoing. Already googled some thing, tried but with no results. Ran troubleshooter and tried updating the drivers (no updates found except one, didn't solved the problem). Anyone who could help with googling? It's an Acer Aspire E1-572G. Thanks in advance!
