Yeh I thought this might be the case. I guess I'll just have to shut down the display and put it in power save mode when I'm out. Thanks again.
Hm, I can't even find it on mine. When you say disabled, do you mean just not using it? Or actually removing that from your system?
The file should be hidden. It will usually be 75%-100% of how much RAM you have. You can disable it by opening up the command prompt as admin and typing in powercfg -h off.
On a standard HDD it shouldnt really take up that much space, but on a SSD you would definitely notice a chunk of space missing. Also sleep will drain the battery faster than hibernate.
