When do I need to change the boot mode?
The default boot mode for your computer is the UEFI mode. If you need to install a
legacy Windows operating system (any operating system before Windows 8.1) on your
computer, you must change the boot mode to Legacy support. The legacy Windows
operating system cannot be installed if you don't change the boot mode.

Cleaning the computer components
Because many of the computer components consist of sophisticated integrated circuit
boards, it is very important to periodically clean the computer to prevent dust buildup.
The cleaning supplies you need to clean the components include: a vacuum cleaner, a
soft cotton cloth, pure water (preferably purified or distilled water) and cotton swabs.
ATTENTION:
Before you clean your computer, disconnect the computer from the electrical
outlet. Clean your computer with a soft cloth dampened with water. Do not use
liquid or aerosol cleaners, which may contain flammable substances.
NOTE:
To avoid damaging the computer or display, do not spray cleaning solution directly
onto the display. Only use products specifically designed for cleaning displays, and
follow the instructions included with the product.
The following are general methods for cleaning the components:
•
You can use a soft cloth to remove dust on the surface of the computer, the monitor,
the printer, the speakers and the mouse.
•
You can use a vacuum cleaner to clean in otherwise inaccessible corners.
•
To clean the keyboard thoroughly, shut down the computer and scrub it gently with
a wet cloth. Do not use the keyboard until it is dry.
Do not do any of the following:
•
Allow water to enter the computer.
•
Use a heavily dampened cloth.
•
Spray water directly onto the surface of the monitor or inside the computer.
LCD monitor should be cleaned daily. Use a dry cloth to brush dust from the monitor
and keyboard every day. Keep all surfaces clean and free of grease stains.
