    Hi, i have a weird problem. I have a Mac Book Pro laptop and sometimes when i close the lid and the computer enters the sleeping mode it doesn't turn on again so i have to turn it off by keeping pressed the power button. Then when i put it back on i see the gray screen at the beginning twice. This doesn't happen always. I thought it was a virus so i formatted the computer and upgraded to Lion but the problem remains. Is there a problem with the power supply or the hard drive? Have anyone had this problem before? Thanks for your time.

    Try resetting the SMC. This should answer most, if not all, of your battery questions:
    It can't be a virus, since none exist. Macs are not immune to malware, but no true viruses exist in the wild that can run on Mac OS X, and there never have been any since it was released 10 years ago. The only malware in the wild that can affect Mac OS X is a handful of trojans, which can be easily avoided with some basic education, common sense and care in what software you install. Also, Mac OS X Snow Leopard and Lion have anti-malware protection built in, further reducing the need for 3rd party antivirus apps.

    didn't work

    I tried resetting the SMC but it didn't fix the problem, the problem remains. Could this be a battery issue? Should i get a new battery?

    This happens on some 2007, 2008, 2009 (one of my MBPs) and even on 2010 MBPs. This seems to be firmware and/or NVIDIA hardware problem. Does not happen on my Early-2011 MBP (which has Intel/AMD graphics).

    If the problem persists, go with your MBP to an AASP. They can replace the logicboard, if necessary.
