iMac (17-inch Flat Panel, 1GHz) Troubleshooting - 7

General Information

Diagnostic Test Points

The iMac has four test points and one ground pad on the bottom of the logic board (next to the PMU and

AirPort Extreme Card). These test points are accessible under the customer access panel via small cutouts

in the plastic shielding (see below).

These test points provide an easy troubleshooting tool for common problems. To use each test point, put the

positive probe of your voltmeter on the test point, and the negative probe on the ground pad.
