ideapad 720S-14IKB Hardware Maintenance Manual

• Always look carefully for possible hazards in your work area. Examples of

these hazards are moist floors, nongrounded power extension cables, power

surges, and missing safety grounds.

• Do not touch live electrical circuits with the reflective surface of a plastic

dental mirror. The surface is conductive; such touching can cause personal

injury and machine damage.

• Do not service the following parts with the power on when they are removed

from their normal operating places in a machine:

–  Power supply units
–  Pumps
–  Blowers and fans
–  Motor generators
and similar units. (This practice ensures correct grounding of the units.)

• If an electrical accident occurs:

–  Caution: do not become a victim yourself.
–  Switch off the power.
–  Send the victim to get medical aid.
