107 If Something Goes Wrong Problems when you turn on the device If you are running on battery power, it is recommended that you do not leave the device in Sleep mode for long periods of time. To charge the battery, leave the device plugged into a live wall outlet for several hours. For more information see "Charging the main battery" on page 65. The Battery light is blinking. If the Battery light is blinking, try the following steps: 1 Connect the AC adaptor to a different power outlet, preferably in a different room. If the device starts normally, there may be a problem with the AC outlet itself, or the voltage level available from it. 2 Verify that the AC adaptor is the correct unit for your device model. The device may not be able to start from an AC adaptor that is rated for less current (amperage) than the device requires, even if the rated voltage is correct, and the plug fits correctly in the DC-IN socket. The labels on the underside of the device and the AC adaptor show the specifications for voltage ("V") and current ("A") for each device. The voltage level must match exactly. The amperage rating of the AC adaptor must be equal to or greater than that required by the device. 3 The battery may need charging, may be depleted, or may be defective. With AC power connected, turn the device on, and then leave the device running for several hours, which will deliver a slow, steady "trickle-charge" to the battery. Once the battery has been tricklecharged, it may begin working correctly again. If the trickle-charging does not prove effective, you can connect to Support Online by going to Toshiba support at support.toshiba.com. The battery light is blinking when the device is on. If the battery light is blinking when the device is on, this indicates a power mismatch. Do the following: 1 Check the OUTPUT specifications on the AC adaptor (for example, DC 19V - 3.95A) 2 Check the INPUT specifications on the bottom of the device. The output specifications of the AC adaptor must match the input specifications of the device.

If Something Goes Wrong
Problems when you turn on the device
If you are running on battery power, it is recommended that
you do not leave the device in Sleep mode for long periods
of time.
To charge the battery, leave the device plugged into a live
wall outlet for several hours. For more information see
“Charging the main battery” on page 65
.
The Battery light is blinking.
If the Battery light is blinking, try the following steps:
1
Connect the AC adaptor to a different power outlet,
preferably in a different room. If the device starts
normally, there may be a problem with the AC outlet
itself, or the voltage level available from it.
2
Verify that the AC adaptor is the correct unit for your
device model. The device may not be able to start from
an AC adaptor that is rated for less current (amperage)
than the device requires, even if the rated voltage is
correct, and the plug fits correctly in the DC-IN socket.
The labels on the underside of the device and the AC
adaptor show the specifications for voltage (“V”) and
current (“A”) for each device. The voltage level must
match exactly. The amperage rating of the AC adaptor
must be equal to or greater than that required by the
device.
3
The battery may need charging, may be depleted, or
may be defective. With AC power connected, turn the
device on, and then leave the device running for several
hours, which will deliver a slow, steady “trickle-charge”
to the battery. Once the battery has been trickle-
charged, it may begin working correctly again.
If the trickle-charging does not prove effective, you can
connect to Support Online by going to Toshiba support at

The battery light is blinking when the device is on.
If the battery light is blinking when the device is on, this
indicates a power mismatch. Do the following:
1
Check the OUTPUT specifications on the AC adaptor
(for example, DC 19V – 3.95A)
2
Check the INPUT specifications on the bottom of the
device.
The output specifications of the AC adaptor must match
the input specifications of the device.
