    My refurbished 7805u laptop keeps crashing when on battery power. At first I thought it was only associated with full screen video, see original post here:
    http://forum.notebookreview.com/showthread.php?t=403486

    But after owning this laptop for the past month, I've determined that it crashes when its on battery power and intense graphics on the screen. When it crashes it is always frozen screen requiring a hard reboot (BSOD does not appear). The intense graphics can be either from full screen video, scrolling through large pics or playing video games (crysis for example). I'm not a avid gamer so I didn't notice everything till I finally downloaded the crysis demo. Played fine with the laptop plugged in. Sometimes the screen blinks, even just typing this message for this forum it blinked.

    When playing the crysis demo, it was only playable (20+ fps) with all high settings and anti-aliasing turned off. I thought you could run it with all high and some AA. Laptop was plugged in of course, otherwise it wouldn't have been playable at all (ie. freeze)

    So what is wrong, the battery, the gpu, the motherboard, something loose inside? What should I do? I believe I got 90 days warrantee, do I go through tigerdirect or the refurbishing company. I'm in Canada btw.

    how do you check the fps, the 20 was my guess. Mind you this is the demo version of Crysis and it's at the beginning by the beach. What sort of fps are you getting with AA at 2x?

    Sounds like the battery may be bad. To check FPS in Crysis press tilde ~ and type r_displayinfo 1
    Play Crysis with it plugged in and see if those problems occur. You should also check the temperature of the components by downloading hwmonitor at cpuid.com. If performance is better plugged in than on battery it's pretty certain that your battery is bad. Also make sure it's not set to go to power saver mode when on battery power.

    I've ran 3dmark06 with and without battery. With battery I get scores around 9300, without it's about 5500.
