A tried to update my BIOS with the .exe file from hp. I downloaded it, installed a then it required restart. I restarted the laptop then the bios start updating and after some steps of updating the screen remains black even after 10 Hours. Ventilators work quite loudly since the bios updating. I am not able to hard shut down, holding the power button does not work And battery is not removable.
Thanks for any hints. Have a nice day.
