Windows repair and reinstall

Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. A battery of this age that swells should be replaced before it damages the trackpad or casing.

Charging port and power repair
We replace worn charging sockets and repair USB-C ports and charging circuits at component level. The adapter is tested first, because it is the cheapest thing to be wrong.
SSD and storage upgrade
The ASUS ZenBook 14X OLED UX5400 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.
Price confirmed before work starts
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the ASUS ZenBook 14X OLED UX5400, along with USB, HDMI and audio port repair, Wi-Fi and Bluetooth card replacement, webcam and speaker faults, BIOS password removal with proof of ownership and data transfer to a new machine.
What we see on the bench
- OLED panels are replaced like-for-like; they are sensitive to pressure, so lid and hinge damage often takes the screen with it.
- USB-C charging faults are a common board repair on recent generations.
- ZenBook memory is soldered on most models, and the keyboard is part of the top case.
