I turned on the computer and it is running slow. What should I do?

You should look at your battery charger to make sure it is connected to the outlet. If you do that and still the power is off, it might be the time to change the battery! Place laptop upside down with the battery facing you. Move latch 1 to the right to unlock battery. Hold latch 2 to the left and simultaneously take the battery out with your opposite hand.
