Reliable Power Supply Repair Services

A PC power supply issue can often be resolved, but the safest solution depends on the device. Desktop ATX or SFX power supplies are usually replaced rather than internally repaired because failed capacitors or heat damage can create reliability and safety risks. APCS first diagnoses whether the problem is truly the PSU, motherboard, cable, battery, charger, or charging port before recommending repair or replacement.

Common signs include a computer that will not turn on, random shutdowns, sudden restarts, fans spinning with no display, clicking or buzzing noises, a burning electronics smell, or visible bulging capacitors. Laptops may show intermittent charging, charging only at certain angles, battery drain while plugged in, or no response from the power adapter. These symptoms should be diagnosed before more damage occurs.

APCS lists a $100 diagnosis fee for power supply and Mac or PC repair services. In some cases, that diagnostic fee may cover the resolution of the issue, depending on the fault and the work required. The diagnosis helps confirm whether the failure is caused by the power supply, charger, battery, motherboard, DC jack, or USB-C charging port.

Yes. APCS handles desktop towers, gaming PCs, workstations, business desktops, small-form-factor PCs, all-in-ones, and laptops. Desktop work may include ATX or SFX PSU replacement, cable management, and load testing. Laptop work may involve charger replacement, battery testing, DC jack repair, USB-C charging port repair, or charging circuit diagnostics across major brands.

The repair process starts with a full power-path diagnostic rather than assuming the power supply is the only cause. APCS checks the adapter, battery, desktop PSU, motherboard, charging port, and related components. This approach helps avoid replacing a working PSU when the real issue is a failed motherboard, damaged DC jack, weak charger, or unstable battery.

APCS offers data recovery support for systems affected by power supply failures, sudden shutdowns, surges, failing drives, and dead laptops. The priority is to stabilize the hardware or safely remove and image the drive before attempting recovery. Power repair and data recovery are often paired when important files are trapped on a device that no longer starts.

Standard availability is Monday through Friday from 8 AM to 5 PM. APCS is closed on weekends, but emergency service may be provided on a case-by-case basis depending on the situation. This is especially helpful for business systems, servers, or critical home-office computers where a dead power supply is causing downtime or blocking important work.

APCS serves the Hwy. 101 corridor from southern Marin County through Sonoma County and up to Mendocino County, including areas such as Healdsburg, San Rafael, Windsor, Boyes Hot Springs, and the North Bay Area. A lengthy distance may incur a travel time charge, especially for on-site repair visits outside the core service corridor.
