Monitoring main battery power
HINT: Be careful not to confuse the battery light ( ), the ON/OFF
light ( ), and the power button light (near the upper-left corner of
the keyboard).
When the ON/OFF light or power button light flashes amber, it
indicates that the system is suspended (using the Windows®
operating system Sleep command).

Determining remaining battery power
Wait a few moments after turning on the computer before trying to
monitor the remaining battery power. The computer needs this time
to check the battery’s remaining capacity and perform its
calculations.
