32-bit Win7 4G memory display only 2.46G available solutions

Generally 32-bit operating systems do not recognize more than 4G of memory, display more than 3G (at least 3G around the available), but I found that my system only shows "2.46G available."

Baidu a bit, the discovery is due to dual graphics card switching models (such as my T400), integrated graphics card ate 500M memory to do the shared video, to disable integrated graphics (disable video card switching) Just enter the Bios-display, set:

1.Default primarty video Device for PCI Express//This is when you start the system using the default instead of the set display (Integrated video card)

2.Graphics Device for discrete Graphics//using standalone graphics mode, switchable Graphics for switchable video mode

3.OS Detection for switchable Graphics detects switchable video card mode for Disable//Disable operating system
