Logic board repair
Faulty laptop mainboard? Replacement is not always necessary.
DataDoc in Cologne isolates charging, startup, voltage and signal faults on laptop mainboards and repairs suitable component-level damage using microsoldering. Devices can also be sent from across Germany.
If there is a short-circuit smell, liquid or unusual heat, disconnect the power supply and battery only where possible without intervention, and stop testing the device.
Typical symptoms
When diagnosis can help.
Short circuit or excessive heat
Faulty capacitors, MOSFETs or loads must be isolated.
No image or unstable startup
Display, storage, voltage and control circuits are examined separately.
Liquid or corrosion
Residue and damaged tracks may cause immediate and delayed faults.
Technical approach
Controlled assessment and targeted repair.
Circuit diagnosis
Input, charging path, standby and main voltages are checked against the board architecture.
Component and track assessment
Abnormal components, solder joints and connections are assessed microscopically and by measurement.
Targeted repair
Repairable faults are addressed at component level, followed by testing under conditions representative of use.
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.
Which laptop brands do you work on?
Feasibility depends on the model, board construction, documentation and part availability. Provide the complete model designation.
Is the mainboard always repaired?
No. Diagnosis first establishes whether the fault is on the mainboard or caused by peripherals, power supply or other assemblies.
What does repair cost?
Without a follow-up repair order, standard diagnosis costs €89.00 including VAT. If you accept the fixed-price quotation, diagnosis is included in the total and is not charged separately.
Can DataDoc also secure my data?
Yes. If data is the priority, state this explicitly when registering so the repair and recovery objectives can be planned correctly.
Is laptop mainboard repair only available in Cologne?
No. DataDoc diagnoses and repairs in Cologne but accepts securely shipped laptops from across Germany. Express collection can be requested for urgent business cases.
