SPARCbook Portable Workstation User Guide
Install the battery as follows (refer to Figure 1-1):
1.
Turn your SPARCbook upside down.
2.
Remove the battery cover by pressing the catch with your
thumbnail towards the side of the SPARCbook. The cover
springs open slightly allowing you to lift it off.
3.
Insert the battery, ensuring correct orientation. The battery is
shaped to make this easier.
4.
Replace the cover.
Now go to “Connecting the AC Adapter” on page 1-5.
Battery Charging
ò
Your SPARCbook charges the internal battery automatically when it is
connected to an AC adapter or optional car adapter. The AC adapter or car
adapter supplies power to your SPARCbook whether your SPARCbook is
operating or not.
ò
The internal battery takes between 1.5 and 4 hours to charge the first
time, depending on SPARCbook model and whether it is operating or not.
ò
The internal battery uses nickel metal hydride (NiMH) cells. One
characteristic of this type of cell is that it takes several full charge and
discharge cycles for them to yield their full storage capacity (to become
conditioned). Once the cells are conditioned, the charge percentage of the
battery pack is accurately indicated on the status display.
ò
The internal battery provides around 45 minutes operating time from a
full charge, depending upon SPARCbook model and the power
management options in operation. See Chapter 4, “Power Management” .
