Good day Nairalanders, please I need your help on how to fix a hibernation/sleep problem on my Acer Laptop. I've tried re installing windows7 (not a fan of Windows 8 ) but nothing has changed. Whenever i click 'hibernate' or 'sleep', the screen jst goes off as if it is actually hibernating and then comes back on showing the 'logon' page. Please I really need the assistance since most of the repairer guys i've met dont even seem to know what hibernation is. Thanks alot for ur anticipated candid inputs
