Troubleshooting

Battery doesn’t charge 
when the AC adaptor 
is attached (Battery or 
Ultra Slim Bay 
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 saver option under Select a 
power plan in the Power Options.
