  1. Hello,
    I have a HP Probook 4540s laptop running Windows 7 64-bit. Just recently I noticed that at nigh my laptop will for some reason turn itself on and then off with a blank screen, I saw that happen a couple of times when I had a bad sleep during night. Just wondering if there is a way to fix that and if that is something to worry about?

    P.S. The laptop is not really off. It's either in sleep or in hibernate mode.

    Thank you. :)

    Your settings for sleep may very well be on. If its working fine after you start using it . This may very well be what its doing.

    The laptop can wake up from sleep to perform tasks such as defrags and updates. This is "enable wake timers" in your advanced power settings.
