MacBook logic board repair, at the component level.

Signs you need this repair

Sound familiar? The diagnosis is always free.

• No power at all: no fans, no light, no startup sound
• Turns on for a second, then shuts off
• Runs, but the screen stays black
• Won’t charge and won’t start
• Restarts in a loop or stops at the Apple logo
• Gets hot or runs the fans hard with nothing on screen
• Died after a spill, a power surge or a cheap charger

Try these steps before you book

1. Use a charger and cable you know work, with enough wattage for your Mac. Try every USB-C or MagSafe port and leave it charging for 30 minutes.
2. Hold the power button for 10 seconds, release, then press it again.
3. If you can hear it or see the keyboard backlight but the screen is black, connect an external monitor. If that works, the fault is in the display path; see MacBook screen replacement.
4. On Intel Macs, try an SMC reset. Apple publishes the exact key combination for each model.
5. On Apple silicon Macs, hold the power button until startup options appear. If they do, the board is alive, and Disk Utility’s First Aid or reinstalling macOS from there keeps your files.

If you have a second Mac, Apple Configurator can revive an Apple silicon Mac’s firmware without erasing data. Its restore option erases everything. If your files aren’t backed up, stop before a restore and book a diagnosis.

Why MacBooks stop turning on

• Liquid damage. The most common cause by far, including small spills from weeks ago. See liquid damage repair.
• A shorted component on a power rail. One small capacitor that fails short can pull a whole power rail down, and the Mac won’t start.
• Charging circuit failure. The chips that negotiate power over USB-C can fail, often after a damaged charger, a faulty hub or a power surge. See MacBook won’t charge.
• Power management faults. The chips that bring the board up in the right order can fail, leaving the Mac stuck before startup.
• Backlight circuit faults. The Mac runs fine, but the display has no light. Often a single fuse or driver part.
• Firmware or software corruption. Sometimes fixable with a revive or a macOS reinstall, without any hardware work.

Component-level repair vs. a new logic board

The standard manufacturer repair for a dead MacBook is to replace the entire logic board. It’s expensive, and on most modern Macs it has a serious side effect: the storage is soldered to the logic board. On every Apple silicon Mac and every Intel Mac with a T2 chip, a new board means new, empty storage, and your files go with the old board.

Component-level repair works differently. Most dead boards have one or a few failed parts, often small, inexpensive components, surrounded by thousands that still work. We find the failed part and replace it under a microscope. You keep your original board, your storage and your files, and the repair usually costs far less than a replacement board.

How our board diagnosis works

Board repair is methodical. We work through the Mac’s power-up sequence until we find where it stops.

1. Visual inspection. Under a microscope we look for corrosion, burnt components and physical damage, front and back.
2. Power draw. We power the board through a USB-C meter or a bench supply and watch how much current it pulls and what voltage it negotiates. A Mac stuck at 5 volts, a sudden high draw, or no draw at all each point to different areas.
3. Rail measurements. We measure the main power rails for shorts to ground and check each stage of the power sequence comes up as it should.
4. Finding shorts. When a rail is shorted, we feed it a small, controlled current and use a thermal camera to find the component that heats up.
5. Microsoldering. The failed part is removed with hot air and precision soldering tools and replaced, along with any damaged pads or connectors.
6. Testing. The repaired Mac is tested under load, on battery and on charge, with every port, the cameras, keyboard, trackpad, Wi-Fi and audio checked.

Apple silicon and T2 Macs: what to know

Apple silicon boards are dense, but power, charging and backlight faults on them are very repairable. A few limits are worth knowing. If the main processor or the storage chips themselves have failed, those can’t be replaced in a way that keeps your data, and we’ll tell you if that’s what we find. Touch ID is paired to the original board, which is another reason repairing your board beats swapping it. And we never bypass Activation Lock or login passwords: the repaired Mac comes back locked to you, just as it left.

What affects the price of a logic board repair

This repair starts with a free check. The price depends on which components failed, how many, whether liquid damage spread across the board, and whether other parts like the battery, display or keyboard also need work. You get a firm price before anything is done. If a full repair isn’t worth it for your Mac, we say so, and if your files are what matter, we can quote a data recovery instead.
