Checking the Battery Pack
Checking the Battery Pack
- Carefully place the computer bottom-side up.
- Remove the battery pack and measure the voltage between the battery
terminals 1 (+) and 3 (-).
| Pin |
Voltage (Vdc) |
| 1 |
+10.0 to +18.0 |
| 2 |
Thermal Detection |
| 3 |
Ground |
- If the voltage is less than +10.0 Vdc, the battery pack has
been discharged or is defective.
- If the voltage is more than +10.0 Vdc,
go to the next step.
- Using an ohm meter, measure the resistance between
battery terminals 2 (T) and 3 (-).
The resistance must be 4 to 30 kilohms.
- If the resistance is not correct, replace the battery pack.
- If the resistance is correct, go to the next step.
- Install the battery pack and
plug the AC adapter cable
into the computer to charge the battery pack.
- If the battery power status indicator
is blinking (orange) and battery charging indicator
is on, replace the battery pack. If the battery is charging normally, the
battery is OK.
