Mac no power
No fan, no chime, no light - Mac dead. Could be power supply, could be SMC, could be a logic board fault. Mac Pro 2019 has diagnostic LEDs that point us straight at the cause. Free diagnosis first, written quote second, work third.
Mohammed, Mac desktop power and board diagnosis
Quick answer
Most "won't turn on" Macs split into three causes. Failed power supply (cheapest fix). Failed SMC controller or stuck SMC state (often a free reset, sometimes a chip swap). Logic board fault - usually power-delivery components around the SoC (more involved). The diagnostic process tells us which cause yours is, and that diagnostic is free.
Mac Pro 2019 is unusually transparent because Apple put diagnostic LEDs on the logic board itself - they tell us in seconds whether power is reaching the board, whether the chassis is detecting the SMC, and whether the boot ROM has loaded. Mac Mini and Mac Studio are less verbose but still diagnosable: we have power-rail probing routines that find the fault on most boards within 30 minutes. Honest result either way - sometimes it's a wall socket or cable, sometimes it's a real repair.
Free intake diagnostic
Bench test: known-good cable, known-good wall socket. Then we probe inside the chassis. 30 minutes to localise the cause on most Macs.
Identify the failed stage
Power supply, SMC, main power-delivery, or boot-rom load. The LED pattern on Mac Pro tells us directly. On Mac Mini and Studio we probe the rails.
Quote the fix in writing
PSU swap, SMC chip replacement, or component-level board work - each has a different price. You see it in writing before any work begins.
Repair + verify
Component sourced, fitted, board powered on bench, then in chassis, then 24-hour burn-in stress test before you collect.
