NUC11PAHi7 BIOS UPGRADE

[TrevorW]

Hi,

I recently upgraded the BIOS to version 0041 using the Intel Assistant tool  to perform the installation. I now have some issues concerning the power button operation. I note in the  0041release notes an errata is flagged : "Please use jumper recovery to update ME settings". Would this apply for a Intel Assistant install?

The particular issue I have is that if the adapter power is removed from the NUC for about 1 hour it will not start up when the adapter is plugged in again. Leaving the adapter connected for about 10 min and then briefly unplugging the power - sometimes 2 times - fixes the problem.

At this stage I am really not sure if the problem  is related to BIOS upgrade

The CMOS battery is only about 6 months old and there are no related error messages

Any assistance would be appreciated.

Hi @TrevorW 

I suggest that in order to open the locked Management Engine settings you should update your BIOS using BIOS Recovery with the Security Jumper Removed method (rather than Express BIOS Update using IDSA). Follow my instructions:

1. Prepare USB stick fully formatted to FAT32 . Format your USB with Quick Format option unchecked. Do not format your USB in MAC (OS) or Linux machine. Use Windows. Download the PATGL357.0041.RECOVERY.zip and extract the PATGL357.cap file. Copy the PATGL357.cap file to the root of this USB.
3. Disconnect the power adapter and remove the bottom panel from your NUC.
3. Remove the Yellow Bios Security Jumper. (page 34 in Technical Product Specification)
5. Insert the USB with the PATGL357.cap file into rear USB slot.
6. Reconnect the power adapter and power ON the NUC. Wait 30 sec - 2min. The Recovery process will start automatically and will end after 2 -5 minutes.
7. When bios recovery is completed, press and hold the Power Button to switch the power OFF, remove the power adapter and replace the Security Jumper (pins 1-2) . Reinstall the bottom panel.
8. Power your NUC ON.
9. Enter Bios setting by pressing F2 during boot process.
10. Press F9(followed by "Y"), to set Bios to default settings. Press F10 (followed by "Y"), to save the settings and exit to O.S. Let the NUC fully reboot.

Hi Leon,

Thanks for the advice. I followed your instructions and everything now works correctly

I would add that if the C: drive is using bitLocker encryption you will be asked for 48-bit drive key following completion of the recovery

Thanks again,

Trevor

Hi Trevor,

I'm glad that you have successfully completed this update. Thank you for your valuable information about Bitlocker encryption.
