Pin 1: +19 to +20.5V Pin 2: 0V, Ground
If the voltage is not correct, replace the power adapter. If the voltage is within the range, do the following: Replace the System board. If the problem is not corrected, see Undetermined Problems on page 106.
If the voltage is not correct, go to the next step. NOTE: An audible noise from the power adapter does not always indicate a defect. 3. 4. If the power-on indicator does not light up, check the power cord of the power adapter for correct continuity and installation. If the operational charge does not work, see Check the Battery Pack on page 97.

Check the Battery Pack

To check the battery pack, do the following: From Software: 1. 2. 3. 4. Check out the Power Management in control Panel In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. Repeat the steps 1 and 2, for both battery and adapter. This helps you identify first the problem is on recharging or discharging.
From Hardware: 1. 2. Power off the computer. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). See the following figure
If the voltage is still less than 7.5 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 doesnt work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU: 1. 2. 3. Reconnect the touchpad cables. Replace the touchpad. 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.
