If your MacBook Air, MacBook Pro or iMac will not turn on, first distinguish a power problem from a display or startup fault. A black screen alone does not confirm a damaged logic board.
At iGenius in Grecia, Costa Rica, the source reports more than 15 years of Apple repair experience, from batteries, screens and ports to board-level electronic faults. This guide helps you prepare an inquiry and decide when to seek a diagnosis.
Initial checks if the Mac is dry and has no visible damage
Apple's guide for a Mac that will not turn on recommends checking power, trying a compatible adapter if available, and disconnecting accessories. It also describes holding the power button for about ten seconds, then pressing it normally. On a laptop with Touch ID, that is the power button.
If symbols or an image appear, the computer is receiving power and may have a startup problem. If it seems on but shows no image, the display and software also need checking. Apple reserves SMC resets for Intel Macs; they are unnecessary on Apple silicon. Follow the instructions for your model.
Mention liquid exposure or impact from the start
These details change the diagnosis. Tell us when it happened, whether the charger was connected and what symptoms followed. Avoid opening the Mac to try parts yourself: inspecting the complete device helps identify the cause.
Also explain any previous repair attempt and the work performed. This helps us understand the condition in which the device arrives.
Battery, charging port, display or logic board?
Different faults can produce similar symptoms. The workshop needs to inspect the equipment before recommending replacement. Board-component repair may be possible if the damage allows it; other cases require evaluating a different part or assembly.
See our MacBook and iMac repair services and logic-board diagnosis and repair. Viability, price and parts depend on the model and findings.
What to send over WhatsApp
- Device family: MacBook Air, MacBook Pro, iMac or Mac mini.
- Year and chip, if known: Intel, M1, M2 or another generation.
- What happens when you connect power and press the button: no response, sound, image or restarts.
- History of impact, liquid exposure or repairs.
- Whether files need to be preserved and whether you have a backup.
You do not need every detail to ask. Our WhatsApp form collects them optionally and prepares a message you can review before sending.
Business repairs and warranty
For several work Macs, tell us how many and which are priorities. We can discuss inspecting the inventory and options for each device without assuming they share one fault.
Coverage varies by work performed. Read the warranty conditions and confirm those applying to your repair. Explain backup and information-handling needs before handing over the Mac.
