34 Chapter 3 Using your Tablet PC
For each battery, you can check the remaining battery power from the battery itself.
To check the battery gauge on the battery
• Locate the battery gauge button and the battery power indicator lights and press the
battery gauge button.(page 35). The indicator lights show the remaining charge. Each
light represents approximately 20% of the available charge.
Charging the battery
When the Tablet PC is connected to AC power, the battery automatically charges until it
reaches full charge, even if the Tablet PC is being used.
If two batteries are installed, the battery with the lowest battery power charges first, then
the second battery charges. The charging sequence is staggered to ensure that both
batteries get as close to being fully charged at nearly the same time as possible. The first
battery (with lowest remaining power) charges to the 90% level, followed by the second
battery charging to the 100% level. Then, the tablet switches to the first running battery.
When running on battery power, the battery with the lowest remaining power discharges
first, then the second battery discharges.
For information about the battery status light, see “Battery status light” on page 12.
CAUTION: To avoid injury, keep the battery within the recommended temperature range
while it is charging. If the battery has been subjected to a hot environment, wait until it
cools to room temperature before recharging it. For more information, see the Safety and
Regulatory Guide included with the Tablet PC.
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 32).
• 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 27.
• Turn off wireless devices when they are not being used.
