What we repair on the MSI Katana 15 HX B14W
Screen replacement
The 15.6-inch panel is matched to the original by part number, including refresh rate and connector type, so games run as they did before.
Price confirmed before work starts
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.
Overheating and fan repair
We strip the cooling system, clean the fans and heatsink fins and renew the thermal compound and pads. We check temperatures under load afterwards.
SSD and storage upgrade
Most configurations of the MSI Katana 15 HX B14W have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.
Price confirmed before work starts
Memory upgrade
Most configurations of the MSI Katana 15 HX B14W have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Graphics repair
The graphics chip is soldered to the board. Artefacts, crashes under load and a black screen with the fans running are diagnosed to the chip, its memory or its power stage, and repaired at board level where it is economical.
Windows repair and reinstall
The MSI Katana 15 HX B14W shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
A new internal battery is fitted and tested through a full charge and discharge.
Price confirmed before work starts
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the MSI Katana 15 HX B14W, 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.
Known issues with the MSI gaming laptops range
- The base label carries an MS- chassis number, such as MS-16R4, which we use to match parts.
- Hinge failures are a well-known problem on MSI's GF, GL and GP ranges; the hinge tears its mounts from the lid or base.
- Thermal servicing is routine work on these: fresh compound, new pads where needed, and clean fans.

Questions
Can the SSD or memory in the MSI Katana 15 HX B14W be upgraded?
The SSD can be replaced, and most configurations have a second M.2 slot. Memory is in slots on most configurations and can be increased.
My MSI Katana 15 HX B14W will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
Is my MSI Katana 15 HX B14W still under warranty?
It may be. Machines from 2025 are often still inside the manufacturer's warranty, which covers faults but not accidental damage such as a cracked screen or a spill. Check that first; we repair what the warranty does not cover.
Where do I find the model number on my gaming laptop?
The base label shows the model name and an MS- chassis number.
