Battery and power management tips
• To lengthen the battery’s usable life, use AC power when you can. The battery will charge
automatically while you run on AC power, so leave the battery in the tablet while you are
working.
• For optimal battery life, use AC power when using a CD or DVD player.
• When running on battery power, place the system in Hibernate or Sleep mode if you are
going to leave it unattended for more than a few minutes (page 38).
• Remember that the display, processor, PC Cards, wireless cards, and accessory drives all
draw on the battery, so adjust properties and disable unused accessories while running
on battery power.
• When running on battery power, adjust the display brightness to a dimmer setting and
enable Dynamic brightness. See “Adjusting the display brightness” on page 32.
• Turn off wireless devices when they are not being used.
