1.2.2 Dual Intelligent Battery Packs
The TM5000 notebook series support the use of two hot plugable intelligent
battery packs (with front panel charge remaining indicators) that allow for
battery removal and replacement while the system is operational (as long as
one battery contains a partial charge). The notebooks use rechargeable
Lithium-Ion (Li-Ion) batteries. These battery packs are ejected from the
front of the notebook using battery eject switches located just above the
keyboard (See Figure 1-4).
NOTE: When battery is 100% charged, all
LEDs extinguish; also LEDs extinguish when
battery is removed from unit.
