Problem Procedure
The battery depletes
quickly even when I
turned OFF the
power of the
computer.
If Sleep and Charge function is enabled, the
computer's battery will discharge during
hibernation or when the computer is turned off.
Connect the AC adaptor to the computer or disable
the Sleep and Charge function.
External devices
connected to the
compatible ports do
not work when
connected to a
compatible port.
Some external devices may not work when
connected to a compatible port if the Sleep and
Charge function is enabled.
Reconnect the external device after turning the
computer ON.
If the external device still does not work, connect
device to an USB port that does not have the
Sleep and Charge function-compatible icon (
) or
change to disable the Sleep and Charge function.
The "USB Wakeup
function" does not
work.
When Sleep and Charge function is enabled, the
"USB WakeUp" function does not work for ports
that support the Sleep and Charge function.
In that case, use an USB port that does not have
the USB Sleep and Charge function-compatible
icon ( ) or change to disable Sleep and Charge
function.
