Mac Repair London carries out logic board repair on the MacBook Air 15-inch M2 & M3 from our London workshop, for home users and businesses.
The 15-inch Air uses the same fanless Apple silicon design as the 13-inch: the processor, unified memory and SSD all sit on one logic board. When that board fails, everything stops, and because the storage is encrypted by the chip, a replacement board would mean losing your files. We repair the original board at component level instead.
Most board faults we see on this model follow a spill through the keyboard or a damaged charger or cable, and they show up in the charging and power circuitry, which is repairable.
About this model: The 15-inch MacBook Air (A2941 with M2, A3114 with M3) gives you a big screen in a thin, fanless body. The large, thin lid is its vulnerability: screens crack from drops and pressure.
Signs it needs logic board repair
- No power or no charging
- Charges but won’t start
- Liquid corrosion
- Short on a power rail
How we do it
Our logic board work is component-level. We inspect the board under a microscope, measure the power rails, use thermal imaging to find shorts, and work from the board schematics to identify the exact failed component. We then replace that component by micro-soldering rather than swapping the whole board.

| Memory | Unified memory inside the chip package (not upgradeable) |
| Battery | Held with adhesive |
| Power / charging | MagSafe 3 plus two Thunderbolt ports |
Before you bring it in
If it partly works (for example charges but won’t start), note exactly what happens and how long it’s been like that. Remember that a replacement board would mean losing the data on this model.

Price
Logic board repair for this model is £450 + VAT. The initial assessment and advice are free, as long as we don't need to open your Mac. If a technician needs to open it and spend time diagnosing the fault, or you need a report for an insurance claim, it is booked in as a diagnostic at £45 + VAT (£54). All prices are subject to inspection, and nothing is done without your approval.
Questions we’re often asked
Why not just replace the whole board?
A new or refurbished board usually costs far more than a component repair, and on this model it would also mean losing the data stored on the original board.
Do I pay if you can’t fix it?
Not for the repair. If it can’t be fixed, you don’t pay for it.
