    Odd thing. I was busy installing Snow Leopard (10.6) and then 10.6.8 (and other app updates) today. Noticed there were "grey beams" running vertically. Light dark. Light dark. This happened to me once long ago. Forgot what I did to get rid of it, But, what I did this time was simply unplug the battery and then put it back into place. Problem solved. No more grey bars . What happened? Any one know what triggered this?

    Happened again when i powered up today. The alternating vertical grey bars were there again. Popped out the battery. Popped it back in. Powered the laptop again. Vertical grey bars wee gone again. Is my battery going bad? Doesn't seem to have problems holding a charge. Ideas?? Will post a few photos. I'm sure it will happen again when i power up again.

    I wonder if "restart" would have solved the problem too. Once I have done this it's fine. It just happens when I power it up for the first time that day.

    Happened a 3rd time. Booted up. Saw the grey bars. Shut down my MBP. Removed battery and reinserted it. Powered back up and the grey vertical bars were gone. Have powered up several times. No more vertical grey bars.I guess the battery was loose. Or not tight enough.

    A picture or video could help. Sounds vaguely like a problem with the voltage in the screen backlight's DC inverter board- how defined are these bars?

    I was going to take a photo the next time it happened but it's stopped since I totally removed the battery and reinserted it. The 2nd time it happened I just undid the 2 latches but didn't totally remove the battery. Only unhinged the battery at the latches then closed it again.

    How obvious was it? It looks like the beams of light you see from spotlights except they were grey. As if there were several grey "spotlights" shooting beams to the top of the screen.

    I think the metal contacts might not have been securely touching the metal contacts of the MBP. Maybe some how the battery latches (2) might have been touched when putting the laptop down or when it was picked up (guess).

    I just posted again to let every one know that there might be a simple fix if something one else runs into this problem. To not immediately panic and take their MBP to an Apple Store.

    Well, it happened again last night. This time I took a photo of the "spotlight effect". And again i had to power down my MBP. Remove battery. Pop it back in. Power back up. "Spotlight effect" gone. For now. Dread having to get my MBP serviced. Here is the photo...
