LifeBook T4200 Series Tablet PC - Section Four Dead Battery Suspend mode shows on the Status indicator just like the normal Standby mode. Once your Tablet PC goes into Dead Battery Suspend mode you will be unable to resume operation until you provide a source of power either from an adapter, or a charged battery. Once you have provided power, you will need to press the Suspend/Resume button to resume operation. In the Dead Battery Suspend mode, your data can be maintained for some time, but if a power source is not provided promptly, the Power indicator will stop flashing and go out, meaning that you have lost the data that was not stored. Once you provide power, you can continue to use your Tablet PC while an adapter is charging the battery. Shorted Batteries The Status Indicator panel uses a symbol inside the battery outline of the Battery Level indicator to display the operating level available in that battery. (See figure on page 16) If this display shows a Shorted Battery, it means that the battery is damaged and must be replaced so it does not damage any other parts of your Tablet PC. REPLACING THE BATTERY Your LifeBook T4200 Series Tablet PC comes with one battery pack; you might want to consider purchasing a spare. By keeping a spare battery fully charged, you can immediately swap with one that is not charged. There are two ways to swap batteries: cold-swapping and warm-swapping. Cold-swapping means swapping batteries when the system has been powered down; warm-swapping is performed when the system is in Standby mode. Cold-swapping batteries To cold-swap batteries in your battery compartment, follow these easy steps: (Figure 4-1) 1. Have a charged battery ready to install. 2. Shut down your tablet and disconnect the AC adapter. 3. Press the battery release latches to open the compartment. 4. Remove the battery from the compartment. 5. Slide the new battery into the compartment. 6. Close the compartment and the battery release latches will click into place. 7. Plug in the AC adapter and turn the power on.

Remove the battery from the compartment. 4. Slide the new battery into the compartment. 5. Close the compartment and the battery release latches will click into place. 6.
