Troubleshooting

Battery doesn’t charge

when the AC adaptor is

attached (Battery

indicator does not glow

orange.)

If the battery is completely discharged, it will not

begin charging immediately. Wait a few minutes.

If the battery still does not charge, make sure the

outlet of the AC adaptor is supplying power.

Test it by plugging in an appliance.

Check whether the battery is hot or cold to the

touch. If the battery is too hot or too cold, it will

not charge properly. Let it reach room

temperature.

Unplug the AC adaptor and remove the battery to

make sure the terminals are clean. If necessary

wipe them with a soft dry cloth dipped in alcohol.

Connect the AC adaptor and replace the battery.

Make sure it is securely seated.

Check the Battery indicator. If it does not glow,

let the computer charge the battery for at least

20 minutes. If the Battery indicator glows after

20 minutes, let the battery continue to charge at

least another 20 minutes before turning on the

computer.

If the indicator still does not glow, the battery may

be at the end of its operating life. Replace it.

If you do not think the battery is at the end of its

operating life, see your dealer.

Battery doesn’t power

the computer as long as

expected

If you frequently recharge a partially charged

battery, the battery might not charge to its full

potential. Fully discharge the battery, then try to

charge it again.

Check the power consumption settings in the

Power Options. Consider using a power saving

feature.
