cannot change the major settings of the BIOS Setup because you 
cannot enter the BIOS Setup.

the BIOS Setup menu.
Before configuring a user password, a supervisor password must 
have been configured. Deactivating the supervisor password also 
deactivates the user password.

These descriptions are for models with a memory 
compartment cover. For the replacement or upgrade 
procedures for the memory of models that do not have a 
memory compartment cover, please ask for assistance from 
your service center.

specification and users can replace the installed memory or add a 
new memory.
Replace or install a new memory module only after shutting 
the computer down completely and separating the AC 
adapter from the computer.
 It is recommended to add memory with the same • 
specifications (the same manufacturer and capacity) as that 
of the installed memory.
The images used for the illustration are of a representative • 
model, therefore the images may differ from the the actual 
product.  
Adding or Replacing Memory Modules

 Disconnect the AC power adapter after turning off the 
computer.

Measuring the Remaining Battery Charge
You can view the battery charge status by completing the 
following procedures.
Confirming the battery charge in the Taskbar
Disconnect the AC adapter and move the mouse cursor over 
the battery icon in the system tray of the Taskbar to confirm the 
remaining battery charge.
Battery Usage Time Information
A battery is an expendable supply, so when using it over a long 
time, the capacity/battery life is shortened. If the battery life is 
reduced to under half of its initial time, we recommend purchasing 
a new battery.
When not using the battery for a long time, store the battery after 
charging it to 30-40% of its capacity. This extends the battery life 
time.
