 
Battery Care
The Notebook PC’s battery pack, like all rechargeable batteries, 
has a limit on the number times it can be recharged. The battery 
pack’s useful life will depend on your environment temperature, 
humidity, and how your Notebook PC is used. It is ideal that the 
battery be used in a temperature range between 5˚C and 35˚C (41˚F 
and 95˚F). You must also take into account that the Notebook PC’s 
internal temperature is higher than the outside temperature. Any 
temperatures above or below this range will shorten the life of the 
battery. But in any case, the battery pack’s usage time will eventually 
decrease and a new battery pack must be purchased from an 
authorized dealer for this Notebook PC. Because batteries also have 
a shelf life, it is not recommended to buy extras for storing.

not a problem with the display.
