Graphics Card 256MB ATI(TM) Mobility Radeon(TM) HD 2600 XT 

There have been serious issues with 2600 and 2400 much like the Nividia 8XXX series. These are issues that are not in the 2900 because there some sections of the chip are disabled in the 2900 but are turned on in the 2600 and 2400. At this time there is no fix, however it is apparently the number one issue to be patched from what Lews has said. When that will happen and if they will be successful is unknown so you would be at a quite a certain amount of risk buying this laptop for Liquid.
