Acer Extensa 500 用户手册

❑

Store the battery pack in a cool, dry place.  The 
recommended storage temperature for battery packs 
ranges from 10 to 30 degrees C.  The higher the storage 
temperature, the faster the battery pack self-discharges. 

❑

The batteries can be recharged about 300 times when 
used as directed.  Excessive recharging decreases 
battery life.

❑

Take care of your battery pack and AC adapter.  See 
“Care and Maintenance” on page xviii of the preface.

You never have to worry about battery power as long as you 
are using the AC adapter.  However, when you operate the 
computer on battery power, pay extra attention to the 
warning beeps and the power indicator on the display 
panel.

The following signals indicate a battery-low condition:

❑

The buzzer generates four short beeps every minute, if 
you enabled the Battery-low Warning Beep parameter in 
Setup.

❑

The power indicator flashes at regular intervals until 
battery power is depleted.

When you receive a battery-low warning, you have around 
two minutes to save your work.  If you do not connect the 
AC adapter within this period, the computer automatically 
enters Hibernation mode if the Battery Low Suspend 
parameter in Setup is enabled and the following conditions 
exist:

❑

The Hibernation file created by Sleep Manager is present 
and valid.  See “Sleep Manager” on page 67.

❑

There is enough battery power left to save system 
information onto the hard disk.
