Hello kindly advise on methodology for bios flash. Can this be repaired without bios flash and if not can it be done with usb? I do have Ez2019+ programmer but not good on soldering.
why you want do it ?
if you want update bios with usb port :
you must download bios update file from hp website and run it . and in one step you must select "create recovery usb flash drive" and create usb recovery . after do that , plug usb to laptop and boot from that usb and update bios .
if you want reprogram bios eprom :
you must have programer and knowledge of soldering . if you haven't one of them you can't do it .
