hot. Make sure the computer is properly ventilated and the Vent/Fan intakes are not blocked. If this
doesn’t cool it down, put the system into
Hibernate mode or turn it off for an hour. Make sure the
computer isn’t sitting on a thermal surface (see “Overheating” on page 1 - 14 ). Make sure
you’re using the correct adapter.
Make sure that your notebook is completely powered off before putting it into a travel bag (or any
such container). Putting a notebook which is powered on in a travel bag may cause the Vent/Fan
intakes to be blocked.
