129 If Something Goes Wrong Power and the batteries My browser cannot find the URL address I typed in. Make sure you separated the domain names of the address with the forward slash (/). Check the spelling of each name and the syntax of the address carefully. A single incorrect letter or missed character will make it impossible for your browser to locate the site. My browser cannot find a site I bookmarked. The World Wide Web is constantly changing. A site you bookmarked yesterday may not be available today or its server may be down for temporary repair. Try again later. Power and the batteries Your computer receives its power through the AC adaptor and power cord/cable or from the system batteries. 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 85. 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.

Power and the batteries

Your computer receives its power through the AC adaptor

and power cord/cable or from the system batteries. 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 85

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.
