Rather annoyingly, when I close my lid, my N130 sometimes remains on, rather than going into standby mode (as it's currently set to) or hibernate (as I had it previously), leaving me with an overheating netbook in my bag.

It seems to be really random as to whether it will succeed in standby. If it fails, when I open the lid it says "preparing to standby". I then have to do a hard reset.

Anyone know what the problem might be?
