1. Turn off the computer's power.
2. Disconnect the AC adaptor and turn on the computer's power - if it
does not turn on then go to Step 4.
3. 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.
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
should glow amber to indicate that the battery pack is being charged,
however, in the event that 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.
5. Charge the battery pack until the DC IN/Battery indicator glows
