HP ENVY x360 - 15-u493cl bio update driver

[andrewnite]

Hello,

I have a HP ENVY x360 - 15-u493cl (ENERGY STAR) laptop that just stopped booting up. I was working one moment then just stop turning on. The fan turn on but the screen stays black and the Cap lock key starts blinking. (It stays lit for about 3 seconds then off for about another 3 seconds.) I brought it to BestBuy to have them run a diagnostic to determine the issue. The told me it was a fried system board and it looked like it was truck by lightning. So I bought a new board and replaced it but it still doesn't boot up. After looking online for possible fixes I found that updating the BIO might be a fix but on the HP website (https://support.hp.com/us-en/drivers/hp-envy-15-u400-x360-convertible-pc/model/10521640) it doesn't list any drivers for updating the BIO.

My question is, does anyone know where I can find the appropriate driver to create a USB or any ideas why is not starting up.

I appreciate the time.
