Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the

If the voltage is still less than 7.2 Vdc after recharging, replace the battery.
To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50%
of the total power remaining when installed in the computer.
If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.
Re-install the battery pack.
If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light
up, replace the DC/DC charger board.
Touchpad Check
If the touchpad doesn’t work, do the following actions one at a time to correct the problem. Do not replace a
non-defective FRU:
1.
Reconnect the touchpad cables.
2.
Replace the touchpad.
3.
Replace the system board.
After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement
can occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware
problem. No service actions are necessary if the pointer movement stops in a short period of time.
