I have two laptops, which my Kids Use mainly for School Use. A 1520 and a recently Purchased 1545.  When Playing a Particular Game , there is a dramatic difference in Video Qualty between the two. BUT the worse of the two is the newest, and I thought more Powerful 1545.

The specs 1545

Intel Core 2 Duo T6400, 2g, 800mhz, 2M L2

3GB, DDR2, *00Mhz

Intel Graphics Accelerator X4500HD

The 1520

Intel Core 2 Duo T5250

2GB, DDR2, 667mhz 2Dimm

128mb NVidia GeForce 8400m G

Both Running Vista Home Premium.

The Games run as well on the 1520 as they seem to on my XPS420.

Is the problem in the Graphics Accelerator. (There were no other options at the time I ordered it)
