If you want to select one power scheme that works well in most situations, we recommend using the Portable/Laptop power scheme as the default power scheme and making the following adjustments: Change the Turn off hard disks, System standby, and System hibernates settings for Plugged in to Never. These settings combined with the default settings for battery power give you optimum power performance for most situations, whether you are at your desk, in a meeting room, on the manufacturing floor, in a client's office, on an airplane, or anywhere you care to take your Tablet PC.

Although these power management settings for the Portable/Laptop are the recommended settings for most Tablet PC users in most situations, you may choose to select different power schemes throughout the day.

For example, if you are at your workstation all day, you could choose the Home/Office Desk power scheme. This power scheme is appropriate when you are plugged into AC power for long periods of time and conserving your battery power is not important.

If you are on the go, you could choose the Portable/Laptop power scheme. This power scheme minimizes the use of power to conserve your battery, but adjusts to your processing needs so that system speed is not sacrificed.

When conserving battery power is the highest priority, you could choose Max Battery Power. Keep in mind, however, that unlike the Portable/Laptop power scheme, the settings under Max Battery Power do not adjust as your processing demands change. The Max Battery Power settings will affect your computer's processing speeds, so reserve this setting for situations that require minimal processing, for example, reading documents and checking e-mail messages.
