Generally, battery life is killed by:
* Active CPU usage
* Read/write to the hard drive
* Display backlight
* DVD/CD drive
* Wireless (like 802.11 or bluetooth)
One thing that actually doesn't hurt battery life is having your RAM eaten
up by many active programs. (If near 100% of your RAM is used, then your
computer will automatically use the hard drive as backup memory, which then
does kill the battery, because the hard drive is power-hungry).
If you notice that having multiple users logged in is consuming battery
life, you can try running perfmon.exe and looking for programs that are
hogging the CPU, reading/writing lots to the disk, or if your memory usage is
near 100%.
