Power
The Mac won't turn on or respond
We inspect devices that appear completely dead, don't recognise the charger, show no image or only boot intermittently.
Diagnostics may include the battery, power input, charging circuits, firmware, storage and logic board.

Liquids
Liquid-damaged or corroded MacBook
Water, coffee, wine or other liquids can affect the keyboard, trackpad, battery, connectors and logic board, even if the device appears to keep working after the incident.
You should power it off, unplug it and avoid switching it on repeatedly. Continued use can spread corrosion or worsen a short circuit.

Display
Black, cracked or lined display
We diagnose displays that show no image, spots, vertical lines, flickering, uneven backlight or faults that appear when moving the lid.
Before replacing the panel, wiring faults, power issues, GPU faults or logic board problems must be ruled out.
See the
Mac screen repair service
.
Battery and charging
The MacBook won't charge or has poor battery life
A depleted battery isn't the only cause of charging problems. The charger, port, cable, USB-C circuitry, MagSafe or the board's power management can also fail.
A proper diagnosis prevents unnecessary battery replacement when the fault lies elsewhere.
Performance
Mac running slowly, freezing or overheating
We check storage, free space, temperature, fans, processes, macOS health and hardware compatibility.
Depending on the model, it may be advisable to optimise the system, perform a clean macOS install or upgrade a compatible component.
See common causes of a
slow Mac.
Data
Lost files or damaged storage
When a device contains projects, photos, accounting, professional documents or client information, recovering data may take priority over repair.
The chance of recovery depends on the model, the type of storage and the extent of the damage.
See our
Mac data recovery service
.
System
macOS won't boot or install
We investigate folder-with-question-mark errors, installation failures, restarts, freezes, damaged partitions, incompatibilities and systems that don't complete an update.
Before formatting, the condition of the storage and the importance of the data must be assessed.

Logic board
Electronic faults on Apple logic boards
We diagnose power faults, short circuits, charging circuits, connectors, damaged components and corrosion.
Where technically feasible, we consider a targeted repair instead of replacing the entire board.
