Servicing your computer is much like with a car. There are things that benefit from a check once a year.
When you bring your device in for a service the first thing we will do is open the device and remove dust from surfaces, vents and fans. This helps the device to breathe easier keeping it cooler.
We then remove the CPU cooler and clean away the old thermal interface material. Replacing this with new, high quality material. This aids in thermal transfer keeping your CPU cool and working optimally.
We then perform a health check on your storage devices.
Be it Mechanical, SSD, M.2 (sata & nvme). and print off a report for you.
This will help in identifying a need to replace and possibly prevent any data loss.
