160 If Something Goes Wrong
Problems when you turn on the computer
The computer displays the WARNING RESUME FAILURE/Windows Error
Recovery – Windows did not shut down successfully message.
To continue, select Start Windows normally. This can happen if
the computer was put into Sleep mode and the battery has
discharged. If you performed a shutdown before this message was
displayed, a program or driver may have prevented Windows® from
shutting down.
Data stored in the computer’s memory has been lost. Data stored in
the computer’s internal storage drive may not be affected.
Always save your data even when you are using Sleep mode. If
your battery fully discharges, information that has not been saved
will be lost. Your computer can be configured to warn you when the
battery is running low see “What to do when the main battery runs
low” on page 109.
If you are running on battery power, it is recommended that you do
not leave the computer in Sleep mode for long periods of time.
To charge the battery, leave the computer plugged into a live wall
outlet for several hours. For more information see “Charging
batteries” on page 105.
The AC power light is blinking.
If the AC power light is blinking, try the following steps:
1Connect the AC adaptor to a different power outlet, preferably
in a different room. If the computer starts normally, there may
be a problem with the AC outlet itself, or the voltage level
available from it.
2Verify that the AC adaptor is the correct unit for your computer
model. The computer may not be able to start from an AC
adaptor that is rated for less current (amperage) than the
computer requires, even if the rated voltage is correct, and the
plug fits correctly in the DC-IN socket. The labels on the
bottom of the computer and the AC adaptor show the
specifications for voltage ("V") and current ("A") for each
device. The voltage level must match exactly. The amperage
rating of the AC adaptor must be equal to or greater than that
required by the computer.
The battery light is blinking when the computer is on.
If the battery light is blinking when the computer is on, this
indicates a power mismatch. Do the following:
1Check the OUTPUT specifications on the AC adaptor
(for example, DC 19V – 3.95A)
