Code 5.3 BIOS time out from embedded controller

[Cisco_Dave]

Unable to boot 15-da0596sa notebook since a small keyboard spillage. Visual of motherboard seems ok but won't boot with code 5.3.

Have tried removing battery for a while. Assume there is no CMOS battery in this model.

Win+B and Win+V doesn't bring up anything on the screen so can't seem to recover it that way.

Any ideas please, can't see BIOS in software centre for any kind of recovery via USB assuming that the BIOS needs reflashing...
