Memory Check

NOTE: Make sure that the DIMM is properly installed into the connector. A loose connection can cause an error.

Do the following:

  1. Boot from the diagnostic diskette and start the diagnostic program.
  2. Go to the diagnostic memory in the test items.
  3. Press F2 in the test items.
  4. Follow onscreen instructions.

Do the following:

  1. Remove the battery pack.
  2. Connect the power adapter and check the power supply.
  3. Disconnect the power adapter and install the battery pack; then check that power supply. If you suspect a power problem, see the appropriate power supply check in the following list:
  • quot;Check the Power Adapter" on page 93
  • quot;Check the Battery Pack" on page 93

Check the Power Adapter

Unplug the power adapter cable from the system and measure the output voltage at the plug of the power adapter cable.

  1. If the voltage is not correct, replace the power adapter.
  2. If the voltage is within range, do the following:
  3. Replace the System board.
  4. If the problem is not resolved, see "Undetermined Problems" on page 107.
  5. 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.

  1. If the power-on indicator does not light up, check if the adapter's power cord is properly connected to the system.
  2. If the operational charge does not work, see "Check the Battery Pack" on page 93.

Check the Battery Pack

Do the following:

Using the software to identify whether a problem occurs while the battery pack during recharge or discharge:

  1. Open Power Management in the Control Panel.
  2. In Power Meter, confirm if the parameters for Current Power Source and Total Battery Power Remaining are correct.
  3. Repeat the steps 1 and 2 for both battery and adapter.

Using the hardware to identify whether you should replace the battery pack or not:

  1. Power off the system.
  2. Remove the battery pack and measure the voltage between terminals one (+) and seven (-). There are seven terminals totally.
  3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

If the battery status indicator does not light up, remove the battery pack . If the charge indicator still does not light up, replace the AC/DC charger board.

If the touchpad doesn't work, do the following procedures in sequence to correct the problem. Do not replace a non-defective FRU:

  1. After rebooting, run Tracking Pad PS2 Mode Driver. For example Syn touch driver.
  2. Run utility with the PS/2 mouse function and check if the mouse is working.
  3. If the PS/2 mouse does not work, then click if the main board to switch board FPC is connected properly.
  4. If the main board to switch board FPC is connected correctly, then check if the FFC on the touch pad PCB is connected properly.
  5. If the FFC on the touch pad PCB is connected correctly, check if LS851 JP1 Pin6 = 5V are pules. If yes, then replace switch board. If not, then go to the next step.
  6. Replace the touch pad PCB.
  7. If the touch pad still does not work, then replace the FPC on Track Pad PCB.

After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement will occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware problem. No actions are necessary to be taken if the pointer movement stops in a short period of time.
