4. Make sure that the battery pack is fully recharged
To avoid an interruption of your operation due to power failure, check the battery voltage when
you start to use your PC in the field. See “Checking the Battery Level” (see Page 79) to check the
battery voltage level.
• Make sure that the battery pack is fully recharged
When you are using the AC adapter and when the battery indicator (
) lights in green, the
battery pack is fully (100%) recharged. When it lights in orange, the battery pack is being recharged.
Battery indicator

ion battery pack, the battery indicator (
) goes out.

Recharging time
(When the PC’s power is off)
Approximately 180 minutes

Cautions
• If the battery pack discharges quickly even after recharging, the battery service life has expired.
Replace it with a new one. (The built-in CMOS backup cells are service parts.)
• The standard recharging times listed above are typical values in an ambient temperature of
20°C to 25°C (68°F to 77°F).
