If your ASUS ZenBook 3 UX390 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. The ASUS ZenBook 3 UX390 is a 2016 laptop with a 12.5-inch screen. The SSD can be replaced but the memory is soldered, so storage is the only upgrade.

Repairs we carry out on the ASUS ZenBook 3 UX390
Screen replacement
Cracked, flickering or lined 12.5-inch screens are replaced with a matching panel. Where the picture comes and goes as the lid moves, we check the display cable and hinges first.

Memory
Memory in the ASUS ZenBook 3 UX390 is soldered and cannot be upgraded. It is worth knowing this before paying anyone for a memory upgrade.
Windows repair and reinstall
This model does not meet Microsoft’s Windows 11 requirements, and Windows 10 reached end of support in October 2025. We can advise on the realistic options, including a lightweight Linux or ChromeOS Flex installation.
Battery replacement
A new internal battery is fitted and tested through a full charge and discharge. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.

Charging port and power repair
The round charging socket wears and works loose. On most configurations it is a separate part on a short cable and is replaced without motherboard work.
SSD and storage upgrade
The ASUS ZenBook 3 UX390 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 3 UX390, 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.
Notes from the workshop
- 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.
- OLED panels are replaced like-for-like; they are sensitive to pressure, so lid and hinge damage often takes the screen with it.
Data recovery from the ASUS ZenBook 3 UX390
The SSD in the ASUS ZenBook 3 UX390 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.
