Charging the batteries

flashes orange indicating that only a few minutes of battery power remain.
If you continue to use the computer while the Battery indicator flashes, the

automatically turns off.
The computer enters Hibernate mode only if Hibernation is enabled in two
places : the Hibernate tab in Power Options and Setup Action tab in
TOSHIBA Power Saver.
