Repairs we carry out on the ASUS AiO A5402
Screen replacement
The 23.8-inch panel is the front of the whole machine. We replace cracked, dark or lined panels and check the backlight circuit, because a black screen on an all-in-one is not always the panel.
Price confirmed before work starts
Windows repair and reinstall
The ASUS AiO A5402 shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
SSD and storage upgrade
The ASUS AiO A5402 has an M.2 slot and, on some configurations, a 2.5-inch bay. Machines that shipped with a hard drive are much faster once moved to an SSD.

Memory upgrade
Most configurations of the ASUS AiO A5402 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
We also carry out motherboard repair, overheating and fan repair, virus removal on the ASUS AiO A5402, along with stand repair, no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
What we see on the bench
- All-in-one PCs use laptop-style parts behind the display, which is removed to reach most components.
- A dark screen with the PC still running usually points to the panel or backlight.
Data recovery from the ASUS AiO A5402
The SSD in the ASUS AiO A5402 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start. Recent Windows machines often have device encryption or BitLocker switched on. If so we will need the recovery key, which is normally saved in your Microsoft account.
