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 at least 16 seconds 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.
