This tab does not appear if the device is not using resources. ❖ The Driver tab, which displays the drivers being used by the device. This tab also provides options for updating the driver or rolling back the driver in case the new version is causing a problem. The tabs that appear in the dialog box vary from one device to another. For more information about Device Manager, refer to Windows® online Help. Power and the batteries Your computer receives its power through the AC adaptor and power cord/cable or from the system batteries (battery, optional secondary 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 not be inserted correctly in the computer. Turn off the computer, remove the battery, clean the contacts with a soft dry cloth (if necessary) and replace the battery. See "Removing the battery from the computer" on page 98. 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.
