Monitoring main battery power
By default the three power plans Balanced, Power Saver, and High
Performance are satisfactory for most people and do not need to be
edited. The Power Saver plan is the best used for maximum battery
time. The High Performance plan will give you the shortest battery
time, but the highest performance from your computer. The
Balanced plan is a compromise between battery time and
performance.
