For Computer, Laptop, and Notebook Repairs
For the repair of computers, laptops, and notebooks, our specialised technical service offers comprehensive and reliable solutions. We fix both hardware faults and software issues, always with a detailed diagnosis that identifies the actual cause of the problem. Repair costs depend on the type of damage and the parts required, ranging from simple fixed-price interventions – such as screen replacement – to more complex repairs, like those on the motherboard.
In addition to rectifying immediate faults, we perform preventative maintenance, including internal cleaning, thermal paste replacement, and temperature checks to prevent overheating. If your device is running slowly, we assess its performance and suggest effective improvements, such as SSD installation, RAM expansion, driver updates, or a complete operating system reinstallation. We also offer professional data recovery in case of information loss.
All repairs and installed parts come with a clearly and transparently communicated warranty, the terms of which vary depending on the component. To provide an accurate and fair quote, we always recommend a preliminary diagnosis by our technical team.
