Comments
Charge times are for a 0% charged
battery pack charging in Tablet PC
(not in an external battery charger).
If the battery pack charge is 90% or
higher when you connect DC power,
the battery pack will not charge, thus
preventing overcharging. Battery life
values are approximate.
Bridge battery supplies power to RAM
in suspend mode for about 5 minutes
while battery pack is removed.
Bridge battery is charged:
• In all modes when external DC
power is connected.
• In On, Idle, or Standby modes
(when system is running) when
external DC power is not
connected.
Provides real time clock power
backup. Approximate battery life is 5
years. (Not field replaceable.)
