When the internal backup battery is low on power, it may not be able to boot
your system properly. You can correct this situation as follows:
❑
Plug in the AC adapter and allow the computer to charge for one hour
while the power is on. Do not use the computer during this time.
❑
After one hour, turn the power off and then on again. To charge the
internal backup battery fully, keep the AC adapter connected for more
than 24 hours after turning the power on. You can use your computer
while charging the battery.
❑
The operating system may become unstable if a lower power state such as
system hibernation is initiated and then changed before the operating system
completely enters the lower power state. To restore the notebook to its
normal operating stability, close all open applications, and slide the power
switch forward and hold it there for four seconds or more to completely shut
down the notebook.
