Only 2.68GB RAM is usable on W7 X86 with 4GB?

Specs: Windows 7 32 bit
I bought a laptop with Windows 7 32 bit and 4GB RAM, which I knew was kind of impossible. However usable is only 2,68 GB of it.
Why? Can I change it? How?
I also have win XP, which has 3,25 GB Ram out of 4.
Does it depend on something?

Thankyou!

I suspect this is due to RAM being shared with the video interface. Because of address space sharing issues the maximum RAM available in a 32 bit OS will usually be about 3 to 3.5 GB, although it can be less. But if RAM is shared with video, which very common in laptops, this will be further reduced.

You may be able to reduced the shared RAM in the BIOS.

Of course with no hardware details provided this is all guesswork.

Well, there is your answer. "Nvidia® Geforce™ GT 330M, 1GB Graphics (Graphics memory up to 2230MB)".

Boot into the BIOS (setup) screens and see how much memory is being allocated.

In other words, Windows 7 32bit will run fine on anything over 2GB of memory. If you reduce the memory used for graphics, then you will be less happy (you purchased a laptop with better than average graphics) since games, photoshop, or video performance would be affected negatively. If you did not need the portability, then you would have purchased a desktop with 64bit, 4GB or more memory, and a good graphics card with it's own distinct graphics memory and you would have both. As stated, a laptop must be a compromise, a balance of needs.

You have to be a little bit crazy to keep you from going insane.
