cases or other materials. They may be damaged due to static electricity generated in your body.
Before handling them, always touch an appropriate metal object to discharge static from your
body.
● Do not touch the printed board surface, soldered areas, or port areas.

● Power to peripheral devices
The power to peripheral devices is generally turned on before powering on the main unit of the
personal computer, however, there are some peripheral devices that will be powered on after
powering on the main unit of the personal computer. Read the manual for peripheral devices.
● Use ACPI support peripheral devices.
This personal computer supports ACPI (one of the power control standards regarding energy-
saving).
If your computer uses the operating system that supports ACPI, and when it uses peripheral
devices, inquire the manufactures of peripheral devices about whether these devices support
ACPI. The use of a peripheral device that does not support ACPI might cause malfunction of the
personal computer and peripheral devices.
● Preparing screwdrivers
Phillips-head screwdrivers may be required for installing or removing peripheral devices.
To avoid damage to the head of the screw, use a screwdriver of an appropriate size.
