At iBrave, we repair and upgrade iMac models up to 2012 in Lisbon and Cascais. These computers often benefit from a full diagnostic of the power supply, hard drive, cooling system and graphics section before parts are replaced. We can repair or replace the power supply at component level, install an HDD or SSD, increase storage capacity and upgrade RAM where the model supports it. Our technicians also diagnose display faults, source a replacement panel when available, clean the cooling system and replace thermal paste. For image loss or graphics instability, we assess the graphics chip and replace it when the repair is technically justified. Logic-board repair, microsoldering and data recovery are also available. After the work, we test startup, storage, temperatures, ports, sound and display output. Warranty terms depend on the repair and installed part.
