MacBook will not start or charge
USB-C Power Delivery, input circuits, power rails or control components may be affected.
Logic board repair
MacBook will not start? Find the fault at component level.
DataDoc assesses Apple MacBook logic boards for boot, charging and liquid damage at component level. The repair objective and scope are separate from data recovery alone. Model-dependent MacBook battery replacement can also be requested separately, with an individual quotation after assessment.
Do not keep charging or switching on a MacBook after liquid ingress, excessive heating or repeated failed starts.
Typical symptoms
When diagnosis can help.
Black screen despite signs of activity
Display power, backlight, image signals and graphics or system circuits must be checked separately.
Liquid inside the device
Corrosion and residue can cause short circuits and delayed secondary damage.
Instability or spontaneous shutdown
Thermal, electrical or signal faults require measurement under controlled conditions.
Technical approach
Controlled assessment and targeted repair.
Power consumption and supply
Input, charging circuitry and relevant voltage rails are measured systematically.
Microscopy and boardview diagnosis
Components, corrosion, tracks and known circuit points are examined selectively.
Microsoldering and functional testing
Faulty components or connections are worked on and relevant device functions tested.
Agree the handover before dispatch.
International shipments require prior case acceptance and agreement on transport costs and the return route. Damaged batteries need individual handover advice.
Frequently asked questionsBack to logic board repair →
Before you send your device.
Does DataDoc also replace MacBook batteries?
Yes, as a separate repair after checking the exact model, battery condition and replacement-part availability. A charging fault does not automatically mean a faulty battery: the power supply, connector or charging circuit may be responsible. You receive a separate quotation and decide before replacement. The logic-board price range is not a battery-replacement price. Do not keep charging a swollen battery, do not open the device and agree a safe handover with us before shipment.
Is the goal data recovery or a lasting repair?
State your objective when enquiring. Limited board repair may enable data access without permanently restoring every device function. Preserving relevant original components is particularly important for hardware-encrypted Mac storage. Scope, risks and prospects are clarified beforehand.
Is logic-board repair cheaper than replacement?
That depends on the fault and model. After diagnosis, you receive an economic assessment and fixed price.
Will my data be preserved?
Board-level repair generally aims to preserve the original board. Data preservation cannot be guaranteed in every case; explicitly identify critical data as a priority.
Can a board that has already been worked on be assessed?
Yes. All previous repair attempts and missing components must be disclosed when registering the case.
What should I do after liquid damage?
Do not switch on or charge the device. Disconnect the power supply and report the case promptly.
