i still havent solved the problem with this model (840 G8), Please lets try once more to fix the bios,or we can try to manually enter the information (model,UUID,product,Feature Byte, ) into the BIOS.
I am sending to attach old and Ec FILES AGAIN-when i turn it on the first time it shows the HP Endpoint error,then it shuts down by itself and cant turn it on again.
