A problem occurs only
occasionally and is
difficult to repeat. Verify that:
1. All cables and cords are securely connected to the
computer and attached devices.
2. When the computer is turned on, the fan grill is not
blocked (there is airflow around the grill), and the fans
are working. If air flow is blocked or the fans are not

If you cannot correct the problem, have the computer
