== Troubleshooting notes ==
The 68-pin Ultra Wide cable runs close to the fan on the side access panel. In the 9650 symptom charts, the first check for no power, for a machine that will not start and for clicking or rubbing noises is that the cable is undamaged and that its Velcro straps hold it clear of the fan. Replace the straps or the cable if they are damaged.<ref name="ss" /> Disconnect this cable from the lower hard disks and release it from its Velcro tie before taking out the power supply.<ref name="ss" />

The other cures are those of the Power Macintosh 9600: reseat the processor card and ROM SIMM, press the Cuda reset button on the logic board, then reset the logic board by unplugging it, removing the battery, disconnecting the power supply cable from the board, pressing the power button and waiting at least 10 minutes before refitting the battery the right way round. The logic board will not run without a processor card. An eight-part error chord at startup means DRAM: replace the DIMMs one at a time.<ref name="ss" />

The clock battery is a 3.6 V lithium cell.<ref name="sp272" /> If it has leaked, see [[Battery Explosion, Capacitor or Corrosion Damage]].
