Stylistic ST5000 Series Tablet PC User’s Guide – Section Two

CHARGING THE BATTERY

The Stylistic ST5000 Series battery can be charged while

it is installed in the Tablet PC.

To do so :

1. Connect a DC power source, such as the AC adapter,

to the DC input connector on the Tablet PC. The

DC Input icon appears in the Status display. If the

battery charge is below 90%, the battery begins

charging and the Charging icon appears in the

Status display. If the battery charge is 90% or higher

when you connect DC power, the battery will not

charge, preventing battery overcharging.

2. Look at the Battery Gauge icon in the Status display

to determine the percent of charge in the battery. See

“Status Display” in Chapter 1 of this manual for a

description of the Battery Gauge icon.

As long as DC power remains connected to the Tablet PC,

the charging process continues until the battery charge

reaches 100%. Approximate charge times shown in

Table 2-2, “Battery Charging Time" are for a fully

discharged battery.

Table 2-2. Battery Charging Time

Also note the following with respect to charging the

battery:

• You can use the system, suspend system operation, or

shut down and turn off the system without

interrupting the charging process; however, using the

system while the battery is charging will cause the

battery to charge at a slower rate, as noted in Table 2-

2, “Battery Charging Time".

• As noted in the procedure above, the system will not

begin charging the battery if the battery charge level

is 90% or higher when the system is initially

connected to external DC power. (This prevents the

battery from being overcharged.)

• The battery uses Lithium ion battery cells which have

no “memory effect.” You do not need to discharge

the battery before you begin charging.

REMOVING AND INSTALLING THE BATTERY

The battery can be removed from the Tablet PC and

swapped with a charged battery. The battery can then be

charged in an external charger if one is available. To

remove the battery from the Tablet PC:

1. Choose one of the following:

• If a charged battery is available, you can suspend

system operation. A built-in “bridge” battery will

maintain the system in Suspend-to-RAM mode for

about 5 minutes while the battery is removed; this

allows time for replacement with a charged battery.

• If a charged battery is not available, save your work

and close all running programs, then shut down

the system or Hibernate (Save-to-Disk).

• Plug in an external DC power source.

2. Slide the battery release latch in the direction

indicated. (See Figure 2-4 on page 26 for location).

3. Pull the battery away from the system, as shown in

the illustration and remove the battery from the

Tablet PC.

If you are using an external battery charger, refer to the

instructions provided with the battery charger.

To install the battery:

1. Orient the battery with the slides in the empty

battery tray. Slide the battery into the tray and press

it firmly until it is seated. When it is properly seated,

the battery release latch should return to position

and lock the battery.

Figure 2-4. Removing the Battery

Once the battery is installed, you can resume system

operation or start and use your system normally.

Battery Charge Level Approximate Charge Time)

90% 4 hours

100% 5 hours

Under Federal, state, or local law, it may

be illegal to dispose of batteries by putting

them in the trash. Be sure to dispose of

batteries in accordance with local

government regulations.
