122 If Something Goes Wrong Power and the batteries NOTE For this model, Slot A is the bottom slot. Slot B is the top slot. If only one memory module is to be installed, it must be installed in Slot A. Power and the batteries Your computer receives its power through the AC adaptor and power cord/cable or from the system batteries (battery and real-time clock (RTC) battery). Power problems are interrelated. For example, a faulty AC adaptor or power cord/cable will neither power the computer nor recharge the batteries. 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 computer. 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. The AC adaptor and power cord/cable work correctly, but the battery will not charge. The battery does not charge while the computer is consuming full power. Try turning off the computer. The battery may be too hot or too cold to charge properly. If you think this is the probable cause, let the battery reach room temperature and try again. If the battery has completely discharged, it will not begin charging immediately. Leave the AC adaptor and power cord/cable connected, wait 20 minutes and see if the battery is charging. If the battery light is glowing after 20 minutes, let the computer continue charging the battery for at least another 20 minutes before you turn on the computer. If the battery light does not glow after 20 minutes, the battery may have reached the end of its useful life.
