Windows 32 bit is only able to USE 3.25 GB, depending on other hardware devices on the system that are mapped into the address space. For the normal user the available memory is the crucial number, not the hardware address range. The battery consumption of memory chips is pretty negligible compared to screen backlighting :-) So turning down your brightness gives you better results.

A 32 bit OS can address two blocks of 2 Gb (2048MB) of memory for a total of 4Gb. IN memory extensionmode 1Gb of SYS memory area can be mapped into USER memory fro 3 Gb possible of user memory. All of this is only about what is directly addressable. 32 bit hardware can install 4 Gb of directly addressable memory. Windows (with no memory adjustments) can address all 4Gb as 2Gb for SYSTEM and 2Gb for User. If you can install 4Gb on a 32 bit laptop you should always install the max for best performance. Many laptops let you use software to turn off memory to save battery when traveling. Whentravelling turn off all bu 1Gb of memory for best battery life. Play with setting to find your "sweet spot" .
