Hello,

is the Surface 8 Pro compatible with PCIe 4 drives or can I only use PCIe 3 ssd?

If not all drives are compatible, which drives work?

Best regards,

Peter

Some changes with the battery? Does PCI 4 SSD use more battery?

Can you provide details on how to do this in Windows 11?

so i been having the same issue as everyone else and what fixed the issue for me was a low level format of the ssd and downloading the AHCI Link Power Management HIPM-DIPM Power Options after you download the power options set it up to active and it should fix the issue btw im using a bg5 ssd

if changing the power settings to active is not working for you then you can try changing it to HIPM+DIPM for both battery and plugged in

My install experience (without the following fix) is that after the installer copied the Windows files and rebooted, the machine will reboot unexpectedly shortly after (or during) the OOBE setup wizard.

I came up with a way to install Windows using the normal installer and avoid reboots during the installation process, this is done by modifying registry settings to apply the necessary changes before windows has finished the installation. Here's how:
1. After Windows installer finishes copying files and initiating a reboot (the stage just before OOBE experience) do not let it boot from the hard drive to finish the installation. Instead of continuing the installation normally, boot again from the installation medium (long press volume up and power button to reach UEFI settings and change boot priority to installation USB)
2. Once the setup window appears again, press Shift+F10 to enter command prompt.
3. On command prompt use DISKPART to mount the partition where the Windows is to be installed (note the partition is already populated with Windows files and was created during the first stage of the install). For me, the partition is on disk0 partition3. In this example I'll mount the disk as drive letter T: using the following command sequence:
  
  select disk 0
  
  select part 3
  
  assign letter=T
  
  exit
4. Now load the registry hive from the offline Windows install using reg load HKLM\OFFLINE T:\Windows\System32\config\SYSTEM
5. using the command prompt window, launch regedit **** to modify registry settings to set AHCI Link Power Management - HIPM/DIPM to Active by default as follows:
Windows Registry Editor Version 5.00
```
[HKEY\_LOCAL\_MACHINE\OFFLINE\ControlSet001\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60] 

"Attributes"=dword:00000002 

[HKEY\_LOCAL\_MACHINE\OFFLINE\ControlSet001\Control\Power\PowerSettings\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60\DefaultPowerSchemeValues\381b4222-f694-41f0-9685-ff5bb260df2e] 

"ACSettingIndex"=dword:00000000 

"DCSettingIndex"=dword:00000000 

[HKEY\_LOCAL\_MACHINE\OFFLINE\ControlSet001\Control\Power\User\PowerSchemes\381b4222-f694-41f0-9685-ff5bb260df2e\0012ee47-9041-4b5d-9b77-535fba8b1442\0b2d69d7-a2a1-449c-9680-f91c70521c60] 

"DCSettingIndex"=dword:00000000 

"ACSettingIndex"=dword:00000000
```
1. In my experience, setting PCI Express Link State Power Management to Off is also required: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\OFFLINE\ControlSet001\Control\Power\PowerSettings\501a4d13-42af-4429-9fd1-a8218c268e20\ee12f906-d277-404b-b6da-e5fa1a576df5\DefaultPowerSchemeValues\381b4222-f694-41f0-9685-ff5bb260df2e] "ACSettingIndex"=dword:00000000 "DCSettingIndex"=dword:00000000 "ProvAcSettingIndex"=dword:00000000 "ProvDcSettingIndex"=dword:00000000
2. close the registry editor window and unload the offline hive using the command reg unload HKLM\OFFLINE
3. Reboot and continue the installation from the hard disk as usual.
Since I am lazy, I scripted this process, so I will not have to type much manually. The patch is made of 4 files. The way I run it is after the first stage of the Windows installation, I'll boot again from the USB drive to the setup window, then launch command prompt, cd to the directory of the patch and run the batch file. Feel free to take a look at neta540/sn740_sp8_win11_install_patch (github.com) for details. I hope this helps some of you folks!

My process was to apply the power options - on the working card - and then I cloned the hard drive using the free version of Macrium reflect.

Not sure if that made any difference - but my system has been stable for days now.

Ghostie above did specify a low-level format as part of their process - did you try that first?
