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 discharges 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 might 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 or change to disable the Sleep and Charge function. The "USB Wakeup function" does not work. When "System ON CDP Charge Mode" or "USB 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 or change to disable both "System ON CDP Charge Mode" and "USB Sleep and Charge function".
