10. HELP AND TROUBLESHOOTING
10.1 Troubleshooting
This section describes some common problems and suggested solutions, as
well as ways to recover your equipment after a crash.
Be aware that the problems and solutions described here are meant only as a
guide. They are not definitive problem solving techniques. For certain problems,
you might need help from your reseller or your service provider.
When you observe a problem, stop the task immediately, because taking further
action might result in data loss or damage. Take a note of what the system is
doing and what actions you performed before the problem occurred. Provide
detailed information to your service provider for quicker problem resolution.
For most problems, follow these steps:
• Restart your device;
• Check your Wi-Fi connection;
• Reset your Wi-Fi connection;
• Plug your device to a wall socket to charge it for at least one hour.
10.2 Display and screen problems
When I turn on the device, nothing appears on the screen.
If the screen is blank, make sure that:
• The AC adapter is connected to the device and the power cord is plugged into
a working electrical outlet;
• The device is turned on (press the power button again for confirmation for 6
seconds to force the turn off and on of the device).
If these items are properly set, and the screen remains blank, the device needs service.
The screen goes blank while the device is on.
If the screen turns black while the device is functioning, that means that it is in
the sleep mode. To turn it back on, press the power button or press the windows
key button.
The screen is unreadable or distorted.
Make sure that:
• The screen resolution and color quality are correctly set;
• The monitor type is correct.
Incorrect characters appear on the screen.
Are the operating system or programs installed correctly? If they are installed
and configured correctly, have the device serviced.
The screen is blank.
If the AC adapter is connected, or if the battery is used, and the battery status
indicator is on, press F4 to make the screen brighter.
Press the power button to resume from sleep mode.
If the problem persists, check if the screen resolution and color are correctly
set, or if the monitor type is correct.
10.3 Sleep problems
The critical low-battery error message appears, and the device turns off.
The battery power is getting low. Connect the AC adapter to the device.
The device enters sleep mode immediately after Power-on.
Make sure that the battery is charged. The operating temperature may also be
too hot. Move it to a cooler environment and try to wake the device.
The device does not return from sleep mode and the device does not work.
Connect the AC adapter, then press the power button. If your device is powered-off,
connect the AC adapter first, and then press the power button to resume operation.
10.4 Sound problems
No sound can be heard from the speaker even when the volume is turned up.
Make sure that:
• The Mute function is off;
• The combo audio jack is not being used;
• Speakers are selected as the playback device.
10.5 Other problems
Your device does not respond.
To turn on your device, press and hold the power button for 6 seconds or more.
If the device still does not respond, remove the AC adapter.
Your device might lock when it enters sleep mode during a communication
operation. Disable the sleep timer when you are working on the network.
The connected external device does not work.
Do not connect or disconnect any external device cables other than USB while
the device power is on. Otherwise, you might damage your device.
When using a high power consumption external device such as an external USB
optical disk drive, use an external device power adapter. Otherwise, the device
may not be recognized, or the system may shut down as a result.
