When plugging the power cord and starting the laptop it gets hanged during the time of windows loading so after starting the windows completely i used to connect the power cord. the problem continued so i installed windows 7 initially having windows vista but after this the problem has increased. Even after the windows is completely loaded and the power is plugged in the laptop hangs instantly or after some time(which was not the problem in vista). I have tried power saving mode but is not helping When i had vista and whenever i used to swith to high performance mode or even balanced mode the laptop used to hang.
Can somebody pls help!!
