Adding or replacing memory modules
Adding memory can help improve your computer's performance. Your computer is like your physical
work area. The hard drive is the filing cabinet where you store your work and the memory is the desk
where you work. When your memory is not big enough to hold all your work easily, like a desk
overflowing with work, your productivity slows down. A great solution to improve performance is to
expand the amount of memory you have in your computer.
The computer will have either one or two memory module slots depending on the model. The memory
module slots are located on the bottom of the computer under the service door. The memory capacity
of the computer can be upgraded by replacing the existing memory modules.
NOTE:
Before adding or replacing a memory module, make sure the computer has the most recent
BIOS version, and update the BIOS is needed. See
.
CAUTION:
Failure to update the computer to the latest BIOS prior to installing or replacing a
memory module may result in various system problems.
WARNING!
To reduce the risk of electric shock and damage to the equipment, unplug the power
cord and remove all batteries before installing a memory module.
CAUTION:
Electrostatic discharge (ESD) can damage electronic components. Before beginning
any procedure, ensure that you are discharged of static electricity by touching a grounded metal
object.
