Checking the Backup Battery (Nonrechargeable) 1. Power off the computer and unplug the AC Adapter from the computer. 2. Open the keyboard, and remove the diskette drive/CD-ROM drive, the battery pack, and the hard disk drive. 3. Remove the top cover and keyboard unit. 4. Open the keyboard unit; then remove the keyboard card. 5. Remove the backup battery from the keyboard card. (Refer to "2060 Backup Battery, Speaker, Standby Battery" on page 494 to remove the battery.) 6. Measure the voltage of the backup battery connector. See the following figure: Wire Red Black Voltage (V dc) +2.5 to +3.7 Ground If the voltage is correct, replace the system board. If the voltage is not correct, the backup battery has been discharged. Replace the backup battery. If the backup battery discharges quickly after replacement, replace the system board. 426 IBM Mobile Systems HMM
