Disposing of used batteries
Lithium-ion (Li-ion) batteries should be disposed of at a hazardous materials recycling
center when it is no longer serviceable. Do not throw it in a waste receptacle because the
battery could end up in a landfill.
Battery and power management tips
To lengthen the batterys 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.
Use AC power when installing software or writing to a CD, and for optimal battery life,
when using a CD or DVD player.
When using battery power, place the system in Hibernate or Standby mode if you are
going to leave it unattended for more than a few minutes (page 33).
Remember that the display, processor, PC Cards, SD cards, wireless cards, and accessory
drives all draw on the battery, so adjust properties and disable unused accessories while
operating on battery power.
When using battery power, adjust the display brightness to a dimmer setting and enable
dynamic display brightness. See “Adjusting the display brightness” on page 26.
Turn off wireless devices when they are not being used.
