| [title] Crumbling insulation on AC wires | |
| [* black] While opening a Mac Mini 2010 I discovered that the insulation on the short wires connecting the AC-In socket to the power supply was cracked. The "twist" operation to remove the AC-In socket from the case caused the wire insulation to crumble to small pieces. In the end, all the insulation fell off, the wires remained completely bare. | |
| + | [* black] Mare sure the Power Supply is not connected to mains AC power while working on it. |
| + | [* black] Discharge the Power Supply before touching the wires by pushing the power button while the AC cable is unplugged then shorting the AC terminals in the plug with a screwdriver. |
| + | [* black] If you don't feel comfortable doing the above, then please purchase a replacement power supply and follow the [guide|3116|Mac mini Mid 2010 Power Supply Replacement|new_window=true] guide. |
