Possible Solution

not restore operation,push the Resume Button.
You may want to close the application and Go
to the Setup Utility Power Savings Menu and
adjust the timeout values to better suit your
operation. (See the Power Savings Menu on
pages 69–72, and Power Management Controls
on pages 20–22.)
2. Install a Power Adapter and then push
the Resume Button. (See Low Battery State
on pages 26–27.)
3. Verify the condition of the battery using the
Status Indicator. (See Figure 2-3 on page 17.)
Replace or remove it if it is shorted.
4. Make sure the adapter is plugged in and the
outlet has power.
