I just bought Dell inspiron 5521..... 2 days ago.... and today i am facing a problem that my laptop doesnt sleep when i close its lid........i dnt knw wether its a software problem or a hardware 1......i have windows 8 installed in my laptop and yesterday i closed it while it was updating.......so i thought may be this is a result of some bad update so i ran system restore....but the problem isnt resolved yet.....and yeah i also played a heavy game to check its graphics card but i dnt think this is relevant to this issue..... so i would be thankful if anybody could guide me here........ and also it would be appreciated that somebody tells me that it is not a very serious problem coz u knw i bought it just 2 days ago :p ............ thanks
