Your device receives its power through the AC adaptor and power cord/cable or from the system battery. Power problems are interrelated. For example, a faulty AC adaptor or power cord/cable will neither power the device nor recharge the battery. Here are some typical problems and how to solve them: The AC power light does not come on when you plug in the AC adaptor and power cord/cable. Make sure the AC adaptor and power cord/cable are firmly plugged into both the wall outlet and the device. If the AC power light still does not come on, check that the wall outlet is working properly by plugging in a lamp or other appliance.
