Understand the main causes of a dead or black-screen MacBook and which observations help distinguish charging, battery, display and logic-board faults. “Won’t turn on” describes a symptom, not a failed part. A MacBook may be completely electrically dead, taking power but not starting, booting with no visible image, or starting and shutting down. Those patterns lead to different tests and very different repair decisions. A known-good compatible charger and cable establish whether power is reaching the machine. On USB-C models, testing more than one port can reveal a port-side or controller problem. A charging icon alone does not prove the battery or logic board is healthy, but it is useful evidence. Listen for startup sounds or fan activity where applicable, check keyboard response and consider an external display when safe. A failed display, backlight or cable can make a functioning computer appear dead. Liquid or impact history changes the probability of each fault. A deeply discharged or failed battery can prevent normal startup, but so can damaged power rails, USB-C controllers, shorted components and firmware issues. Current draw and board measurements help separate those possibilities before expensive assemblies are replaced. On modern encrypted MacBooks, access to files may depend on the original board and security architecture. If the only copy of important data is on the machine, tell the workshop before resets, board replacement or other destructive recovery steps are considered. This guide is general information, not a remote diagnosis. Stop using a device that is swollen, smoking, hissing, excessively hot or otherwise unsafe. If your question is not here, call, email or message the team. No. Display, backlight, cable, graphics, firmware and power faults can create a similar black-screen symptom. No. Repeated power attempts can worsen some electrical and corrosion faults. No. Walk-ins are welcome at Union Street and Gloucester Road. Booking helps the team prepare and gives you a preferred time. The website records a preferred slot. The team confirms availability after checking the fault, parts and workshop capacity. Eligible repairs include the warranty stated on the booking or invoice for the fitted part and related technical fault. New impact, liquid damage and unrelated faults are excluded. Most hardware repairs do not intentionally erase data, but data can never be guaranteed on a faulty device. Back up important information whenever possible. Questions to ask about diagnosis, parts, timing, warranty, data and collection before authorising a repair. A realistic guide to same-day repairs, diagnosis time, part availability, workshop queues and final quality checks. A practical guide to finding iPhone, Samsung, Pixel, iPad, MacBook and Windows laptop model information before requesting a repair quote. A better repair decision starts with the right information, not just a price. The complete model or model code helps the team check the correct part, expected repair route and availability before you travel. A useful quote explains the known work, part choice and what could still change after diagnosis. Extra work should not be added without authorisation. Maintain a current backup where possible and avoid sending passcodes or passwords through ordinary enquiry messages. Your booking reference and invoice make aftercare, warranty questions and future repair history much easier to understand. Book an assessment, message the team or walk in at either Bristol shop.
