Correcting a Low Battery Condition
A low battery condition exists when the battery has less than 10 percent of its power remaining. You should resolve the low battery condition before your computer loses all battery power.
When your computer loses all battery power, it begins Hibernation, a process that cannot be interrupted. If Hibernation has begun, you must wait for your computer to finish saving your information and turning off automatically before trying to correct the low battery condition. Once your computer has entered Hibernation mode it cannot be used; however, you can only use it again by plugging it into an AC adapter or replacing the drained battery with a charged one.
Your situation (such as availability of an AC wall outlet) will determine which solution to use to correct a low battery condition. Use one of the following options:
•Connect the AC adapter – This solution allows you to continue working without being interrupted and simultaneously charges the drained battery. You do not have to turn off your computer before connecting the AC adapter. Your computer automatically switches to AC power once you connect the AC adapter.
•Replace the drained battery with a charged one – If you cannot connect the AC adapter but you have a charged battery, you can change the battery and continue working.
a.Save your work.
b.Turn off your computer (or initiate Hibernation).
c.Replace the drained battery with the charged one.
d.Press the Power button to turn on your computer.
e.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 on your computer and resume your work.
