2500 SX/25 (250-1610)             BATTERY               Faxback Doc. # 1127     

The battery powers the clock, enabling it to maintain the correct time and 
date when the computer power is off. Replacement batteries (23-162) are 
available at Radio Shack stores.

The clock battery should last at least three years with normal use. When it
fails, the computer will not retain time and date information correctly.

If the computer does not restart when you turn it on or reset it, it could
indicate that the battery is weak or dead. Before replacing the battery, refer
to "Main Logic Board Layout" to locate the battery socket.

To replace the battery:

1. Gently lift the battery clip and remove the old battery from the socket on  
   the main logic board.

2. Position the new battery with the positive (+) side up. Lift the clip an    
   insert the battery. 

3. Run the setup utility to enter the system time and date.

WARNING: Danger of explosion if battery is replaced incorrectly. Replace only 
with the same or equivalent type recommended by the manufacturer. Discard used 
batteries according to the manufacturer's instructions. Do not dispose of in 
fire.
