Main Battery

Should you notice the life of a charged battery pack is short, replace it with a new one. Follow these instructions below to replace a battery pack.

1.Save your data, turn off unit power, and close the dis- play panel. Disconnect any cables attached to the unit, such as the AC adapter cable.

NOTE

If you receive messages indicating that both the main battery and the sub-battery (back-up bat- tery) are very low, replace the back-up battery first.

If a drained main battery is not replaced, the back- up battery drains more quickly than normal.

2.Have a new Lithium-Ion battery pack available.

3.Slide the battery cover lock to the unlocked position.

4.Slide the main battery bay cover toward the arrow and remove the cover.
