Troubleshooting
This chapter advises you on what actions to take when solving common computer problems that may be caused by issues with
hardware or software.
Preliminary Checklist
Here are the initial steps you should follow before taking further action when encountering any problem:
1. Try to identify and isolate which part of the notebook is causing the problem.
2. Make sure that you turn on all peripheral devices before turning on the notebook.
3. If you are having trouble with an external device, make sure that the cable connections are correct and secure.
4. Make sure that the configuration information is properly set in the BIOS Setup program.
5. Ensure that all the device drivers are correctly installed.
6. Make note of your observations. Are there any messages on the screen? Do any indicators light up? Do you hear any beeps?
Detailed descriptions are useful to the service personnel when you need to consult someone for assistance.
7. If any problem persists after you follow the instructions in this chapter, contact an authorized dealer for help.
Preliminary Checklist
• To prevent possible damage to the battery, the device does not allow the battery to charge if the internal temperature of
the battery gets too low (< 5°C or < 41°F) or too high (> 50°C or > 122°F). If possible, charge the battery in a location with a
moderate temperature of around 20°C (68°F).
• If possible, turn off the device while the battery is charging.
• If the battery is new or has been stored for a week or more, follow this procedure:
1. Make sure the device is turned off.
2. Remove the battery.
3. Connect the AC adapter to the device and an AC wall outlet, and then
turn on the device by pressing the button.
4. Let the device complete the boot process. Then reinstall the battery.
• Allow the system to remain idle for one hour with the AC adapter connected to the device.
• The Battery Power LED lights when the battery starts charging.
• If the battery still fails to start charging after an hour, remove the battery, wait several seconds, and then install it again.
• If the battery does not begin charging within several minutes, return the unit for service.
Battery Problems
The battery does not charge
• Under moderate temperatures, about 20°C (68°F), the device’s battery takes approximately 4 to 5 hours to completely
charge.
• As the battery temperature approaches the ends of its temperature range (5°C/41°F to 50°C/122°F), it may take longer to
charge the battery.
The battery takes longer than seven hours to charge.
• Calibrate the battery. If your battery is new or has not been used for several weeks, calibrating the battery accurately sets
the gas gauge.
• As your battery ages, its maximum capacity naturally decreases and even the best maintained batteries eventually need to
be retired. Consider replacing the battery if you are not getting the usage you need from it.
• To meet ENERGY STAR® requirements, Wake on LAN is enabled by default. If running on battery power this may decrease
battery run time. To change Wake on LAN settings, open the Device Manager, Network Adapters and select the LAN device.
Open the device Properties and select Power Management. Disable the Wake on LAN setting by unchecking. Allow this
device to wake the computer.
The battery doesn’t hold charge for very long.
• This may indicate that the charging process terminated prematurely.
The gas gauge isn’t full after charging the battery.
