The MacBook Air 15-inch — introduced with M2 in 2023 and updated with M3 in 2024 — is the largest MacBook Air Apple has produced, offering a 15.3-inch Liquid Retina display in a fanless chassis with MagSafe 3 charging and two Thunderbolt USB-C ports. It shares the flat design language of the M2 and M3 13-inch Air and the same passive thermal management, but the larger chassis and bigger display introduce slightly different failure patterns — particularly around hinge stress on the heavier lid assembly and battery capacity.
Brentworth reviews MacBook Air 15 mail-in repair requests for MagSafe and USB-C charging failures, liquid damage, no-power conditions, display faults, and board-level diagnosis across M2 and M3 models.
Use the intake form to describe the device, the fault, and the result you want. The more specific you are, the easier it is to give you a useful answer.
The MacBook Air 15 charges via MagSafe 3 or either Thunderbolt USB-C port. Charging failures — no LED activity, intermittent charging, 'plugged in, not charging', or charging that stopped after a knock or spill — may involve the MagSafe port, a USB-C connector, the Thunderbolt controller, or the logic board. Try a different cable and charger on all three charging paths before submitting intake.
The MacBook Air 15's slim chassis means liquid entering through the keyboard or ports reaches the logic board quickly. Post-spill faults may appear immediately or develop over days as corrosion progresses. Power off the machine after any spill and do not turn it on again before it has been cleaned and assessed. Brentworth performs ultrasonic cleaning before any board fault is diagnosed.
A MacBook Air 15 that shows no response to the power button, starts briefly before stopping, or boots to a black screen may have a battery fault, a charging circuit problem, a firmware issue, or a logic board failure. The M2 and M3 chip integration means board-level faults behave differently from Intel-era hardware — diagnosis requires appropriate methodology.
The 15.3-inch display is the MacBook Air's largest panel and the heavier lid assembly places more leverage on the hinge than the 13-inch models. Backlight failure — confirmed by a faint image under direct light — hinge-angle-dependent flickering from display cable stress, and physical damage from drops or a hard close are all reviewed at intake. Hinge wear on the 15-inch Air can progress faster than on the 13-inch due to the lid weight.
Keyboard and trackpad faults on the MacBook Air 15 follow the same pattern as the 13-inch M2 and M3 models — liquid exposure and physical damage are the primary causes. A trackpad that is physically raised, stops clicking in areas, or produces phantom input may have a swollen battery pressing from underneath. Battery swelling is a safety issue requiring prompt assessment.
The MacBook Air 15 carries a larger battery than the 13-inch, but capacity still degrades with charge cycles over time. Abnormal drain under light use, failure to reach a full charge, or a 'Service Recommended' battery health warning in System Settings each warrant assessment. Swelling — visible as a bowed bottom case or a raised trackpad — is a safety concern regardless of age or cycle count.
Brentworth reviews mail-in repair for MacBook Air 15-inch M2 and M3 models. Include the chip generation in your intake — it is shown in About This Mac under the Apple menu.
Try a different MagSafe cable and check the port for debris. If the issue persists, try charging via USB-C on both Thunderbolt ports. Describe in the intake which charging paths fail, whether there is any LED activity on the MagSafe connector, and any events that preceded the fault.
Yes. Brentworth charges a non-refundable inspection fee of $70 for repairs that require disassembly to diagnose. This fee is credited toward the repair cost if you proceed. If you decide not to proceed, you receive a written breakdown of the fault.
Many can. Power the machine off immediately after any spill and do not turn it on again before it has been cleaned and assessed. Brentworth uses ultrasonic equipment to clean affected areas before diagnosing board condition. If repair is not viable, that is communicated before any costs are incurred.
Flickering that changes with hinge position typically indicates cable stress — the display cable is being strained at a specific angle. The heavier 15-inch lid places more leverage on the hinge than the 13-inch model, which can accelerate cable wear. Left unaddressed, this can progress from intermittent flickering to permanent backlight loss. Submit intake describing when the flickering appears.
A physically raised trackpad that no longer clicks properly is a common sign of battery swelling — the expanding battery cell pushes against the trackpad from underneath, preventing the click mechanism from depressing. This is a safety issue. Do not leave a swollen battery in use. Submit intake promptly.
Submit an intake form with the chip generation — M2 or M3 — the fault, and any relevant history. Brentworth will confirm the assessment approach before you ship anything.
