We repair the MSI Crosshair 15 B12U at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 15.6-inch gaming laptop from 2022. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

What we repair on the MSI Crosshair 15 B12U
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
Windows repair and reinstall
The MSI Crosshair 15 B12U shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.
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
A thermal service covers fresh compound on the processor and graphics chip, new thermal pads where needed and both fans cleaned. It is the usual cure for throttling and loud fans under load.
SSD and storage upgrade
Most configurations of the MSI Crosshair 15 B12U 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 Crosshair 15 B12U 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.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the MSI Crosshair 15 B12U, 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
- Thermal servicing is routine work on these: fresh compound, new pads where needed, and clean fans.
- 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.
Data recovery from the MSI Crosshair 15 B12U
The SSD in the MSI Crosshair 15 B12U 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.

Questions
Can the SSD or memory in the MSI Crosshair 15 B12U 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 Crosshair 15 B12U 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.
Why does my MSI Crosshair 15 B12U overheat or slow down in games?
Usually dust in the heatsinks and thermal compound that has dried out. A thermal service fixes it in most cases. If temperatures are normal and it still slows down, we test the graphics chip and power delivery.
How much does a MSI Crosshair 15 B12U screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
