HP Pavilion 15 n077so BIOS

[kwsths]

Hey folks. I have an HP Pavilion 15 n077so, and the caps lock key flashes 2 times at boot. WIth a quick googling I came to the conclusion that the BIOS is corrupted. Can I reset it? The serial number is 5CD3451KZ0. Many thanks!

Hi:

Below is the link to the latest BIOS update I could find for the HP Pavilion 15-n0xx notebooks with Intel processors and chipsets:

Watch these videos for how to create and use a BIOS recovery flash drive with the above exe file using another Windows PC:

Thanks, this worked! The laptop works perfectly now. I was just wondering, can I output the bios over the HDMI output? I have another pretty much identical laptop, n205sv, with the AMD dGPU on it. Its display is broken, and I'd really like to use it again.

You're very welcome.

Unfortunately, what you want to do is not possible as the HDMI port is not activated until the graphics driver is initialized and that doesn't happen until after Windows boots up.

So, in order to access the BIOS, you need to have a working display on the notebook.

Ah, I see. Thanks much nonetheless!

Anytime.

Glad to have been of assistance.
