How Long Does a Computer Repair Take?
Most software issues (viruses, slow performance, settings, Windows problems) are fixed the same day, often within an hour once the engineer is on-site or connected remotely. Hardware repairs (screens, batteries, hard drives) depend on parts availability, common parts are usually fitted same-day; less common parts may take a day or two to source, and we’ll always tell you the timeline before starting.
