hi
I did bios update for this laptop, but something went wrong and I lost the serial, model even mac adress:
Model: 15-da0103ng, serial: CND8488CXW, ProdID= 4ET85EA#ABD.
I tried to use hp bios configuration tool, but always i get access denied and cannot set config file
I read my bios:

ok, i solved the problem by programming a virgin bin from HP, in my case it is 084A6.bin, after that it says the bios is in unlocked mode, i used hp bios configuration tool to inject serial etc.... and returned to locked mode
