Troubleshoot

Blue Screen

 

There are a few known cases when Windows 10 blue screen can happen:

 

1. New installation or update to Windows 10 version 1909

 

Windows 10 version 1909 has problems with TXE “Intel Trusted Execution Engine Interface” driver. After installation or update to this version the following restart(s) will result in blue screen.

This can be avoided by disabling the “Intel Trusted Execution Engine Interface” driver before restarting after install / update.

To disable the driver go to device manager and find “Intel Trusted Execution Engine Interface” in the list. It will have the little warning sign on it.

Right click on “Intel Trusted Execution Engine Interface” and picked disable device.

 

If this is not done before the installation it can be done within Windows safe mode.

Windows will offer an option to repair/troubleshoot windows after two successive blue screens. Choose Advanced Options, Troubleshoot, Advanced Options and Startup Settings then restart button.

Windows boots in startup settings mode. Choose 4 to enable safe mode. Windows will start in safe mode without blue screen. Disable the “Intel Trusted Execution Engine Interface”.

To disable the driver go to device manager and find “Intel Trusted Execution Engine Interface” in the list. It will have the little warning sign on it.

Right click on “Intel Trusted Execution Engine Interface” and picked disable device.

 

This was only noticed on Windows 10 version 1909, version 2004 doesn’t seem to have this issue any more.

 

2. Going into the sleep mode with default BeFREE power off mode (low energy)

 

On our BeFREEs (except BF07) we have implemented an energy saving mode as default, turning off all power to the mainboard and SLEEP is not supported.

This was normally not the issue, but with some Windows 10 updates the default action for power button was changed to SLEEP mode not shut down. Now when power button is pressed windows go to SLEEP mode instead of shutting down and since this is not supported by default BeFREE power settings the computer shuts down, unexpectedly for Windows, as it aims to go to sleep mode, this can cause all kind of trouble, especially if it happens during installation of drivers.

 

There are basically three solutions:

a) Set the action of the power button to turn off, not sleep.

b) In our software ChangeMe change the power mode to "standard", not energy saving.

c) In the BIOS, disable "suspend"; the computer cannot go to sleep mode anymore. In BIOS: Advanced -> Power Mode -> ACPI Sleep State: Suspend Disabled.

 

Depending on the use case you can choose any of the above. Usually the device would be running 24/7, option 3 would be the best and safest. If the device is set up to go to sleep after a while, option 2 is the best.

 

3. C-States reporting

 

With some combination of Windows and user software we had reports of BeFREE unexpectedly freezing during normal operation. In this case the device has to be forced (with long press) to shut-down which can result in blue screen at the next start.
