Windows provides the following
plans to help you manage your computer's power:
Balanced. Offers full
performance when you need it and saves power during periods of inactivity. This
is the best power plan for most people.
Power saver. Saves power by
reducing system performance and screen brightness. This plan can help laptop
users get the most from a single battery charge.
High performance. Maximizes
screen brightness and might increase the computer's performance in some
circumstances. This plan uses a lot more energy and will reduce the amount of
time that a laptop battery lasts between charges.
High performance doesn't appear on the battery meter by default.
To turn on High performance, open Power Options by clicking the Start button , and then
clicking Control Panel. In the search box, type power options, and then click Power
Options. Under Select a power plan, click Show additional plans, and then click High
If these plans don't suit your needs, you can create your own power plan, using one of these plans as a starting point.
