HP Pro C640 G2 (Elemi) Auto restart / Power on

Hi,
I have a serious problem with this device.
They automatically restart immediately after being shutdown.
Or/and they often automatically start the device, even though the device has been confirmed to be powered off before. This happens frequently and drains the battery of many devices.
is there any way to fix this?
Thank you so much,

This is known. There is no fix

There is a bug in googles ec source code
