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.

Performing Daily Maintenance Tasks

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.
