Toshiba Tecra W50-A - Manual (Page 123)

Disabled Conventional USB battery charge while PC is
powered On.
The "System ON CDP Charge Mode" may not work with certain external
devices even if they are compliant with the USB specifications. In those
cases, use a USB port without "USB Sleep and Charge function" or disable
“System ON CDP Charge Mode”.
It is recommended that AC adaptor be connected to the computer while
supplying USB bus power (DC5V, 1.5A).
When your computer battery capacity is too low to continue, "System ON
CDP Charge Mode" may not work. In those cases, connect the AC adaptor
and reboot the computer.
Always use the USB cable that was included with your USB device.
When "System ON CDP Charge Mode" or “USB Sleep and Charge
function” is enabled, the “USB Wakeup” function may not work. In that
case, use a USB port without "USB Sleep and Charge function" or disable
both “System ON CDP Charge Mode” and “USB Sleep and Charge
function”.
TOSHIBA Face Recognition
TOSHIBA Face Recognition uses a face verification library to verify the
face data of users when they log in to Windows. The user can thus avoid
having to enter a password or the like, which makes the login process
easier.
To access this utility, click Desktop -> Desktop Assist -> Tools &
Utilities -> Face Recognition.
TOSHIBA Face Recognition does not guarantee the correct
identification of a user. Changes to the likeness of a registrant, such
as hair style changes, wearing a cap, or wearing glasses may effect
the recognition rates when such changes occur after the registrant had
registered.
TOSHIBA Face Recognition may incorrectly recognize faces that are
similar to a registrant.
For high security purposes, TOSHIBA Face Recognition is not a
suitable substitute for Windows passwords. When security is a high
priority, use your established Windows passwords to log in.
Bright background light and/or shadows may prevent a registrant from
being recognized correctly. In that case, log in using your Windows
password. If recognition of a registrant fails repeatedly, refer to your
computer documentation to learn ways to improve recognition
performance.
