My laptop is 4736Z, CPU: Intel T4200. I remember that the 4736z uses GL40.
But I checked my laptop with CPU-Z, SiS Sandra and EVEREST. All of them reported that the chipset is GM45.
CPU-Z: Intel GM45/ GM47
SiS Sandra: Acer GM45 Mobile Controller Hub
Everest: Intel Cantiga GM45
Now I intend to update the memory. Is there anybody who successfully installed 1 x 4G stick in the 4736z?
