replacement, consider the following when determining how long a charged battery pack
should last:
Power conservation settings
•
Hardware configuration
•
Software applications
•
Installed options
•
Display brightness
•
Hard drive usage
•
Changes in operating temperature
•
Type and number of installed PC Cards

energy required by the Notebook and the energy stored in the battery pack.
