I have an Asus m513u ryzen 5 5500u laptop

For some reason the prochot flag is set and the cpu throttles to 400mhz when the battery is installed.
On AC with the battery removed the laptop runs fine. 

I have dumped the current bios, used uefitool to extract the PbsSetup and CbsSetup.
Used ifrextracter to convert to text.
I have used ru.efi to try and make changes.
I cant figure out what to change to disable prochot, or to get the laptop to run fine with battery.

This is the first time I am trying something like this.
Pls, any advice will be greatly apreciated]]>

I am looking for a modded BIOS for my ASUS Z97-PRO (Wi-Fi AC). I am currently on the latest official version 3503.

I have two specific issues that require BIOS modification:

1. TPM 2.0 Support: I have a physical TPM 2.0 module (20-1 pin) plugged into the board, but the BIOS does not recognize it (it only supports 1.2 by default). I need the TPM 2.0 modules (Tcg2) backported from a newer ASUS board (like Z170/Z270).
   
2. EFI GOP Update: My RX Vega 64 causes Error Code 99 during boot when Secure Boot is enabled or CSM is disabled. I need an updated AMD EFI GOP driver injected to fix this compatibility issue.
   
3. Optional: If possible, please add Re-Size BAR support (ReBarDxe).
   

Motherboard: ASUS Z97-PRO (Wi-Fi AC) Current BIOS: 3503 (Official CAP file) Official Download Link: https://www.asus.com/pl/supportonly/z97-pro(wi-fi%20ac)/helpdesk_bios/

I can flash the modded BIOS using the USB BIOS Flashback feature, so the CAP capsule signature shouldn't be an issue.

• Model No: RZ09-0220 | Product Code: RZ09-02202E75-R3U1
• S/N: BY1747A13900750

BIOS chip:

• Macronix MX25L6406E M2I-12G (SOIC-8)
• 64Mbit / 8MB, SPI, 3.3V
• Date code: 58408900 K174583

Situation:
Board was hit by power transients during a tropical storm. System is completely dead — no POST, no display, no fan spin. Suspect corrupted/blown BIOS flash. All other hardware tests clean.

What I have:

• CH341A programmer
• Spare MX25L6406EZNI-12G chips (DigiKey)
• Plan to unsolder the original chip and read/compare before writing

What I need:
A clean dump from an identical or closely matching board (RZ09-0220, ideally RZ09-02202E75-R3U1). Razer support declined to provide firmware.

Happy to post my dump once I have the programmer in hand — could be useful for others with this board.

It seems that what i really need is a good method to change HWID so that Windows says it is not activated. I did try lately to change .rom with HxD and the afuwin-3.05.04 which it worked half way at least for a few boots. Problem i had is that somehow my Intel Ethernet adapter stopped working which isn't really an issue for me as this Motherboard has 2 BIOS chips and even if i brick one i still have the other.
I bought an original Windows key in hope that it will overwrite the one stored on MS servers but that doesn't work either whatever i do this Windows Enterprise key overwrites everything and executes some custom .ppkg files (i did try to change default app for ppkg files to notepad).
Is there anything i can do to fix this please i am soooooo tired of this issue all i want is to unlink my PC from the Enterprise key forever, i do not have any game bans that would be the least of my issue.
I am not a professional but i do understand a bunch of stuff and i am also very fammiliar with terminals so there is no problem. Also is there any way i could get to downgrade Intel MEI or overwrite it? My goal is to completely reset the mobo as it was when i got it, RAM training and everything from scratch.
I also attach a few screenshots so you can see what i'm talking about so even though i am using Pro the registry has Enterprise entries. Yes i already tried (me and a bunch of ms help agents) to change them and custom install again it always shows up as Enterprise as soon as i connect to the internet and Event Viewer spits out UserDeviceRegistration each boot. It's much more to say but these are a few good examples. Also the last MS agent told me that this happens because i have an Enterprise code embedded in my mobo (OEM) but i am sure i don't because when i open RW Everything and try to look for the ACPI > MSDM i cannot find it...

If you need me to upload anything please let me know, also if you want me to pay i have no problem with it.

I can provide photos if needed.
The system originally came with an NVIDIA GeForce 8400 GS (MXM, 256MB DDR2), which works perfectly with the internal display.

---

Goal
Upgrade the GPU to a GeForce 9600M GT (MXM-II, DDR2, 64KB VBIOS, MS-V149B).

---

Current situation

• The 9600M GT powers on and works
  
• System boots normally
  
• Windows loads
  
• External display (DVI) works perfectly
  

BUT:

• No image on internal display (LVDS)
  
• No BIOS/logo → completely black screen
  

---

What I tested
1. BIOS settings

• Tried PEG / IGD / Auto options
  
• No change
  

2. Hardware checks

• GPU properly seated
  
• Cooling and power OK
  
• External output confirms GPU is working
  

3. VBIOS analysis

• Dumped VBIOS from both GPUs
  
• Compared 8400 GS vs 9600M GT using hex tools
  
• The VBIOS files are significantly different, not just minor variations
  
• Differences are spread across many regions, not isolated blocks
  

4. VBIOS mod attempt

• Tried copying suspected LVDS/init sections
  
• Result: GPU failed to initialize (black screen everywhere, required recovery)
  

5. Cross comparison

• Compared my 8400 GS VBIOS with Acer versions
  
• They are also very different, not matching dumps
  
• Suggests OEM-specific variations or different board implementations
  

6. Recovery & tools

• I already prepared a proper flashing setup
  
• Used NVFlash and tested recovery procedures
  
• I have full backups of all original VBIOS files
  
• Comfortable with reflashing and recovery
  

---

Additional note
When working on the VBIOS, I’m not sure if I may have been looking at the wrong sections.
I was not able to clearly identify LVDS-related tables or display initialization blocks, and the structure of the VBIOS makes it difficult to isolate the relevant parts.

---

Possible causes (not sure)

• Differences between G86 (8400 GS) and G96 (9600M GT) display initialization
  
• LVDS panel configuration or timing mismatch
  
• OEM-specific VBIOS or motherboard limitations
  
• Different LVDS wiring or output routing
  

I'm not sure which of these is the actual cause, so any insight would help.

---

Question
Has anyone:

• Successfully used a 9600M GT MXM in an AIO system like this?
  
• Found a compatible VBIOS that enables LVDS output on similar hardware?
  
• Seen similar incompatibilities when moving from G86 to G96?
  

---

Summary

• 8400 GS → internal display works
  
• 9600M GT → external only
  
• System boots fine
  
• Issue = LVDS initialization / firmware incompatibility
  

I can provide motherboard and GPU photos if needed.

1. Remove write protection on CpuSetup EFI variable
  (GUID: B08F97FF-E6E8-4193-A997-5E9E9B0ADB32)
  to allow disabling CFG Lock at offset 0x43 for CPU undervolting.
2. Unlock advanced BIOS menu options if applicable
  (power limits, XMP, voltage settings, fan control, etc.)

CONFIRMED:
- CpuSetup is write-protected at firmware level
- setup_var.efi returns WRITE_PROTECTED from UEFI shell
- modGRUBShell setup_var_cv returns error 0x8000000000000008
- MSR 0x3A = 5 (CFG lock enabled), MSR writes blocked
- Fpt.efi dump and flash tools available and working
- Intel Boot Guard may be active (13th gen Clevo platform)

CONFIRMED LOCKS (from IFR extraction of actual BIOS dump):
- CFG Lock:            CpuSetup offset 0x43  = 0x01 (need 0x00)
- Overclocking Lock:  CpuSetup offset 0x10E = 0x01 (need 0x00) 
- UnderVolt Protection:CpuSetup offset 0x381 = 0x01 (need 0x00)
- BIOS Lock:          PchSetup  offset 0x1C = 0x01 (need 0x00)

All blocked by CpuSetup write protection at firmware level.
Full 32MB BIOS dump attached (obtained via Fpt.efi from UEFI shell).
Flash tool available: Fpt.efi + FlashMe.nsh from Clevo package.
