A technician-led guide to loose charging sockets, USB-C negotiation, battery faults and motherboard power problems on Windows laptops. A laptop that says “plugged in, not charging,” charges only at an angle or remains completely dead can fail at several points in the power path. The charger, cable, connector, battery and motherboard all need to be considered before the repair is reduced to a charging-port replacement. Barrel-style DC jacks can loosen, crack solder joints or damage their cable harness. USB-C charging adds communication between the charger and laptop before higher power is delivered. A USB-C port may carry data correctly but still fail power negotiation, or one port may work while another does not. A charger can deliver enough power to light an LED but fail under load. Damage to the cable or connector can also be intermittent. Comparing the customer charger with a known-good compatible unit prevents an unnecessary laptop repair when the accessory is actually at fault. A worn or disconnected battery may allow mains operation but no charging, while a shorted or swollen battery can create more serious power behaviour. If the case is separating, the trackpad is lifting or there is unusual heat, stop charging the laptop and arrange safe assessment. When the port and charger are healthy, the failure may sit in input protection, charging controllers or downstream power rails. Electrical measurements are more reliable than replacing the battery and port in sequence until something changes. 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. Not necessarily. Some USB-C ports support data only, while others accept power. The laptop specification and port markings matter. No. Charger, firmware, USB-C or DC-jack and motherboard faults can also cause that message. 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.
