Putting laptop in sleep mode is a common thing that we do to save power and perform our work at a later stage without much delay. But for some users there is a problem while they try to resume from sleep mode.
As the resuming begins, a blank screen appears with a mouse pointer and stays until you press any key or click the mouse. This problem may be fixed by a HotFix named KB958685 released by Microsoft for Vista and Windows7 users and should be only used if you are facing this problem.
