I recently bought an MSI GF63 Thin 12UCX laptop (i5-12450H, RTX 2050). The problem I’m facing is that the BIOS shows the motherboard as “B450M Mortar Max (MS-7B89)” — which is clearly incorrect since that’s a desktop board, not a laptop.
Because of this incorrect info, MSI Center and fan control software don’t recognize the laptop properly, causing overheating even with light use.
What I’ve tried so far:
Flashing the official BIOS (E16R8IMS.117) from MSI
Resetting EC
Reinstalling Windows and MSI utilities
None of these fixed the issue. The motherboard name remains wrong in BIOS.
I suspect the DMI information got overwritten or corrupted somehow.
Unfortunately, I cannot send the laptop to a service center right now.
I’m looking for help with:
A method or tool to restore or rewrite the correct DMI info for my model
Guidance on using tools like NbDmiFit, RU.efi, or any other recommended solution
I can provide BIOS dumps or screenshots if needed.
Most likely NVRAM residuals, the system board/SPi needs a “COLD” reset.
Main battery/2pin CMOS battery off for 15m or so.
Upon 1rst reboot, enter bios load defaults and save, reboot and enter bios again for specific settings needed or boot normaly.
Another disk with pre-installed OS from a B450M Mortar Max (MS-7B89) system was used/booted once at least…rigth?
I bought the laptop second-hand, but I haven’t used or connected any drive from a B450M Mortar Max system myself.
The wrong motherboard name was already showing in the BIOS when I got it. I’ve tried flashing the official BIOS and doing EC resets, but it didn’t fix it.
I’ll try the full cold reset as you suggested and see if anything changes.
I followed the steps exactly as you described — I disconnected both the main battery and the CMOS battery for over 15 minutes, then booted into BIOS, loaded defaults, and rebooted.
Unfortunately, the BIOS still shows the wrong motherboard name (“B450M Mortar Max”)
Dump and share here full bios dump, if you want.
FPT v16 dump is enough.
EDIT: As predicted…
Again, a full reset must be done and should solve it, MSI exe bios updates won’t work.
A more “drastic” solution envolves swapping NVram volumes / delete entries from bios updates to a dump for using Intel FPT tool if possible or doing full IC programming also will clear it… but really none of these are my primary choice for such issue…usually, “tiny” things are always changing in UEFI firmware development…
DMI, OEM and bios tags/table data is OK as: MS-16R8 MEGABOOK MSI_NB 16R81116
I would contact MSI inquiring an optional recover bios method (FULL)
DO NOT update to latest bios 117/ME16135 firmware, without the issue resolved…
MSI support told me to send the laptop for service, but I prefer not to.
All I need is to change the model name, so MSI Center can detect my laptop correctly.
I’m having cooling issues, and without proper fan control, the laptop is almost unusable.
Please let me know if there’s a way to manually edit the model name or DMI info.
Full IC programming
(Though you said they’re not your first choice)
I’d really appreciate it if you could help me with more detailed steps or guidance on any of these — especially using Intel FPT or how to safely reset everything (including NVRAM) to get MSI Center to detect the laptop correctly.
I understand the risks and I’m comfortable taking responsibility. Just need the right direction.
There’s some things that just can’t be taught with a snap of a finger…some actions requires a bit more user knowledge and seem you have none, in similar issues/methods/tools.
Sorry but there’s plenty of info on the forum, about working with a cheap CH341A, learn and practice on spare/death system board.
About the Intel tool…not going lose my time with it as i do not have “time” for teaching more than i do helping users on the forum. It requires further steps and tools like the one i linked previously as example.
I do suggest you seek a professional IT worker on your area, its not such fortune to pay for this kind of service and you won’t stay without the system as long as if was sent back to MSI service.
(You can remove your shared file if you want, as it contains your system data)
That’s all from me, good luck.
try use fpt to rewrite bios region, without battery, then plug off ac power.
or grab amidewin ( you can find it in some lenovo official bios ) to write dmi stuffs.
