Turn off the computer's power.
Disconnect the AC adaptor and turn on the computer's power. If it
does not turn on then go to Step 4.
Operate the computer on battery power for five minutes. If you find
that the battery pack has at least five minutes of operating time,
continue operating until the battery pack is fully discharged. However,
if the DC IN/Battery indicator flashes or there is some other warning
to indicate a low battery condition, go to Step 4.
Connect the AC adaptor to the DC IN 19V jack of the computer, and to
a wall outlet that is supplying power. The DC IN/Battery indicator
glows amber to indicate that the battery pack is being charged.
However, if DC IN/Battery indicator does not glow, this indicates that
power is not being supplied. Check the connections for the AC adaptor
and the power cord.
Charge the battery pack until the DC IN/Battery indicator glows white.
