HP Laptop 17-cn4517TU BIOS Corruption Issue - Need the Correct BIOS File

[SophiaGrace77]

Hello,

A few months ago, I purchased an HP Laptop 17-cn4517TU, but due to my own carelessness, the laptop is now malfunctioning.

The power indicator light turns on, but the screen remains completely blank.

I suspect the BIOS became corrupted when I disassembled and reassembled the laptop without removing the battery.

To fix the BIOS issue, I extracted the .bin file from the official BIOS update .exe provided by HP’s website and attempted to flash it using a ROM Writer.

However, the result was the same — the screen didn’t turn on.

I extracted two 16MB .bin files and flashed them individually, but neither worked.

When I tried flashing a different BIOS firmware, the screen did turn on, but the system couldn’t boot because the firmware wasn’t the correct one.

At this point, I’m fairly confident that the BIOS is corrupted, and the laptop is unable to boot.

Request:

Could someone kindly provide the correct BIOS file for the HP Laptop 17-cn4517TU?

If I made any mistakes during my troubleshooting process, I would greatly appreciate any advice or corrections.

If anyone has faced a similar issue or knows how to resolve BIOS corruption, I would really appreciate your help!

Thank you in advance!
