Thx - BIOS backed up and I have reflashed.
If I run UBU 1.45 I can see that there is updates to microcode - Think current is revision 1C and UBU can update it to 1Fh.
Could this potentially be a method for getting support for the 5650U processor or is the potential risk of getting bricked big?
Lets see if reflash works…will update thread in hopefully +30 minutes
