Replace the Drained Battery with a Charged One
If you cannot connect the AC
adapter but you have a charged
battery, you can change to
battery power and continue
working. To replace the drained
battery with a charged one,
complete the following steps:
1. Save your work.
2. Turn off your Notebook
(or initiate Hibernation).
3. Replace the drained battery with the charged one.
4. Press the Power button to turn on your Notebook.
5. Resume your work.
When AC power becomes available, repeat these same steps
but insert the drained battery and charge it by plugging in the
AC adapter.
Suspend Your Work
If you cannot plug in the AC adapter and you do not have a
charged replacement battery, start Hibernation by pressing the
Power button. When a power source (AC or battery) becomes
available, press the Power button to turn your Notebook on
and resume your work.
