@dglt - OK, thanks, I will look all that over tonight when I have more time. How do you know his MTM number?
While I looked around to find this, none match what you mention, but I found ALL of the below, how do you know which applies to his system (other than what I surmised near the end)?
On Gsync, if his screen has been replaced with cheaper version, Gsync will never work..

For 15" 15IRHg
81UH008JPH
Or
81UHCTO1WW
or
81UH0005RK (Russian)

81UF0000US - Iron Grey US
81UH0000US - Iron Grey US
81UH00C1US - Iron Grey US
81UH0001US - Iron Grey US

Which do you have ^^ based on the specs there? Looks like the screen type, graphics card type, and stock SSD/NVME is the major differences. I assume you probably can't tell what stock HDD/SSS/NVME came with it, but you should be able to find LCD spec info using some kind of app, maybe HWINFO65 or AIDA64?

Two of those have NO GSYNC. So it looks like another key part of that is what LCD you have, which is expensive and probably something they replaced when rebuilding this system, and surely used a cheaper screen.

Well, I guess only one has RTX 2060 >> 81UH0000US, and only three are 15IRHg, with the last two on right side coming with 2070 GFX cards.
But, that still may not be correct MTM for you, since latter part of this # is region based. Not sure where you are, or where this system originated either.
I assume this wont matter much, we can probably just use that one above, don't you think?

i went by the serial number (picture attached)

NV156FHM-N4J is the only G-Sync panel they use for that model, if thats the one thats in there it should be good to go. (unless its some garbage aftermarket equivalent)

if the serial number provided is correct then so should that info be, still under warranty as well.

Yes, but this is a repaired, rebuilt system, sold by third party reseller and probably cobbled together several new parts.
It may be new screen and new board, usually screen needs replaced long before motherboard would, in many laptop repair/purchase/resell type cases anyway.
That's all I mean, maybe why screen may not be correct type anymore. But yes, we shall know more when we see what happens once some system info is fixed

Internal Serial number (Not "Lenovo SN") provided on fake sticker by reseller does not match the one I found inside, that's why I re-tagged you guys to ask you to check your inner sticker to confirm
And then I realized that part w/ sticker may not be original, or may be original with other board which we know may or may not be original also. It does not match the one given on the reseller sticker

Yes, if the "Lenovo SN" serial is correct, or at least valid for this model, that MTM shown in your image it should work and hopefully fix all this, thanks!

@ndthtnt - Program this back in, then enter BIOS and load optimal default, save/reboot back to BIOS and then show me image of BIOS Main page
Then, hit windows and do the driver stuff dglt mentioned and see if you can get GSync working.

@ndthtnt - No worries, that's why I asked for images, thanks.
Please dump this via FPT and send to me, we'll check to see if the changes were actually flashed in or not (if yes, then I will also need to change this info in NVRAM too probably)
But, I bet it wasn't flashed in there

FPTw.exe -a 0x600000 -l 0x115000 -d pad1.bin


* Edit - @ndthtnt - VarsM?? There was/is no varsM for BIOS 1.05!!
So that is NOT good you did this!! Please reflash other previous BIOS you were using, using stock method (upgrade) then flash varsM we made for that.
Then downgrade back to 1.05 again, and flash ONLY the BIOS region I sent you, NO VARS for this BIOS version was ever made, and you should not flash anything from newer BIOS version into system for this older BIOS version
Luckily you did not brick it!

@Lost_N_BIOS

Thank you for your quick reply. Please find it in the attachment.

@ndthtnt - Please see my edit above, you're very lucky you didn't brick the system!

Yes, very lucky it didn't brick! I'd say flash back in original 1.05 vars, or varsm we made for that, but we did not do any of that here because it was not needed.
Hopefully all will be OK and none of that will prevent fixing things properly now.

From your pad dump above, the modified info was not flashed in during FPT flash, so once you're ready again we'll do it manually.

Here's the fix file, flash it back via >> FPTw.exe -a 0x600000 -l 0x115000 -f pad1SysInfo.bin
http://s000.tinyupload.com/index.php?fil...293182504957741

@Lost_N_BIOS
I've just upgraded to 1.08, flashed VarsM, returned to 1.05 via stock method.

So the next steps now are:
1. FPT the BIOSreg105FixM1.bin
2. FPT the pad1SysInfo.bin
3. Reboot and load optimal default

Is this process correct?

@ndthtnt - Since no other changes were made in BIOSreg105FixM1, you can skip #1 and just do #2-3 (ie flash post #54 as outlined, then do BIOS optimized, reboot and check everything)
After you do all this, if still no change, dump pad1 again using this command and send to me to check >> FPTw.exe -a 0x600000 -l 0x115000 -d pad1check.bin

@Lost_N_BIOS

Yah there's still no change. Please find the pad1check in the attachment

@ndthtnt - Yes, still not there
Here, flash this using command below - http://s000.tinyupload.com/index.php?fil...091799521833355
FPTw.exe -a 0x600000 -l 0x115000 -rewrite -f pad1checkfix.bin

Then reboot, load optimized, save, reboot and check and then if still same do command below
FPTw.exe -a 0x600000 -l 0x115000 -d pad1postfixcheck.bin

If this does not go in, you may need flash programmer to fix this!

@ndthtnt - No worries here, whenever you get to it. I'll either be here, or not, no rush
