Immediate shutdown or no power at all
Conductive residue can cause short circuits in multiple supply paths.
Logic board repair
Liquid damage to a MacBook, iPhone or laptop? Switch it off now.
DataDoc in Cologne examines affected logic boards microscopically and electrically, treats suitable residue and repairs technically viable corrosion and short-circuit damage after your approval. Devices can also be sent from across Germany.
Switch the device off immediately. Do not charge, apply heat or test it again. Time matters because corrosion can progress.
Typical symptoms
When diagnosis can help.
Individual functions fail
Local corrosion may affect keyboard, charging, display, wireless or sensors.
The device initially kept working
Corrosion can progress later, even if the device worked after the incident.
Cleaning did not restore stable operation
Surface cleaning does not automatically remove damage beneath components or inside tracks.
Technical approach
Controlled assessment and targeted repair.
Documented visual and microscopic inspection
Entry points, residue, corrosion and affected areas are systematically recorded.
Electrical diagnosis
Short circuits, leakage currents and missing supply voltages are isolated.
Cleaning, repair and testing
Suitable areas are professionally treated, damaged components replaced and 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 rice help after liquid damage?
No. Rice removes neither conductive residue nor corrosion beneath components and may waste valuable time.
Should I switch the device on to dry it?
No. Electrical current combined with moisture can cause additional damage.
Can it still be repaired after several days?
Possibly, but corrosion progresses. Prompt diagnosis improves the starting conditions.
Can I commission data recovery only?
Yes. If data is more important than lasting device function, the commission is directed accordingly.
Can I send a liquid-damaged device from Cologne or elsewhere in Germany?
Yes. DataDoc is based in Cologne. Regular cases can be securely shipped from across Germany; express collection is available for critical and business cases.
