Power Macintosh 6500: Difference between revisions
P4 verification: cite Apple's own Service Source volume for this machine (hosted here) for the electrical specification and battery threshold, and link the documentation page |
Red-link sweep: retarget delegation links to the pages that actually exist (LC 550/LC 580/Performa 6100 sub-pages do not, the Performa 550/580 and Power Macintosh 6100 ones do), fix the malformed 'Macintosh Power Macintosh 5400' title, and de-link targets with no page |

Service documentation
[edit | edit source]Apple's own service manual is hosted here as Performa/Power Macintosh 6400 and 6500 Series Service Source. It gives the 6500 a maximum continuous power of 140 W against 220 W for the 6400, and — importantly — a line voltage of 90–130 or 180–264 VAC, configured manually. This is not an auto-ranging supply, and the Basics chapter has a dedicated Voltage Switch section. A machine imported between regions can arrive set for the wrong mains. The PRAM cell threshold is replace below 3.0 V.[4]
Additional Procedures in that volume carries "6500 — Distinguishing Video Jitter from Blur" and a "Blurry Video Solution", which is Apple documenting a known display fault on this model, plus a Processor Fan procedure.[4]

The voltage switch
[edit | edit source]This machine has a manually set voltage switch and Apple's own wording is that it "must be set correctly to avoid damaging the computer." Insert a screwdriver in the slot and set it to show "115" for supplies between 100 and 130 V or "230" for supplies between 200 and 270 V. Apple gives the line voltage as 90–130 or 180–264 VAC configured manually, at 47–63 Hz — not a universal auto-ranging input. Apple's volume also prints a country-by-country voltage table, and notes that some countries use two standardised voltages.[5]
Things that are not faults
[edit | edit source]- With external speakers attached the subwoofer works as a bass speaker; without them it produces
full-range sound instead of just bass. The subwoofer balance control only does anything when external speakers are connected.[5]
- Inserting a plug into either output jack disconnects the internal speaker, and the rear jack is
muted when headphones are in the front jack. That is by design.[5]
