  1. No.

    Based on the specs for that laptop it has a Mobility Radeon HD 3200. The cause of not having anything displayed on the screen would be:

    1. Malfunctioning graphic chip
    2. corrupt video driver
    3. the display itself is not longer function properly
  2. Thanks, how do I find out which problem it is? I have the motherboard out of the computer
  3. connect it to a monitor and with the keyboard and a f key try swapping over to ext video port. if there no video or boot screen then you have a power or mb issue.
