Before doing so, follow the steps as detailed below. 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 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 15V jack of the computer, and to a wall outlet that is supplying power. The DC IN indicator should glow blue, and the Battery indicator should glow orange to indicate that the battery pack is being charged, however, in the event that DC IN indicator does not glow this indicates that power is not being supplied - check the connections for the AC adaptor and the power cord. 5.
