Common repairs

Screen

Cracked, black, flickering or lined screens. We fit a matching panel and test it for dead pixels, brightness and colour.

Battery

Drains fast, shuts down with charge left or shows a service warning? We fit a new battery and check the charging circuit.

Keyboard

Missing, sticking or dead keys and spill damage. On some models the keyboard is fixed to the top case, and we tell you before starting.

Charging

Not charging, or only at an angle? We test the charger, the USB-C or MagSafe port and the power circuit to find the fault.

Liquid damage

Switch it off, unplug it and do not dry it with heat. We clean corrosion off the board and replace what cannot be saved.

Motherboard

No power, no picture or random shutdowns often come down to one failed part. Board-level repair costs far less than a new board.

Data recovery

If it will not start, we can often still recover your files. Storage is soldered, so this can mean repairing the board.

Good to know

Apple silicon Airs have no fan, so overheating is rare, but the thin display panel cracks easily if something is trapped when the lid closes. Storage is soldered to the logic board, so recovering files from a dead board needs board-level work.

Questions

Is it worth repairing my MacBook Air 15-inch M3 A3114?

In most cases, yes. We will tell you honestly if a repair is not worth it.

Will my files be safe?

Most repairs do not touch your storage, but back up anything important if you can. If it will not start, tell us and we will take extra care.

How do I find my exact model?

Open the Apple menu and choose About This Mac.

How long will it take?

Many repairs are done the same day when the part is in stock. If we need to order a part, we give you a date when you drop it off.
