Question Asus laptop no screen after interrupted bios update

[Ckorin]

Hello, this is my first thread so i don't know if it's the right section.

I have a laptop Asus X541U. Did an upgrade from hdd to ssd. Installed windows 10 and was doing some upgrades from windows update. The second time i restarted the laptop it entered the bios and i think it was upgrading the bios because there was a loading bar, it freezed and couldn't go on so i forced the shut down but after that the laptop never woke up again.
I tried:

• hard reset by removing the battery and then put it back again and connected the AC adapter
• disassembled the laptop and left only AC adapter and display flat conneted. the moment i plugged the AC adapter (no keyboard so no power button) the laptop turned on (power led on) but screen remains black
• after that, i plugged back in the battery but acts like there's not, so it won't turn on until i plug the AC adapter.
• assembled back again the laptop but nothing changes.

I wanted to flash the bios but i can't even get to enter it because the screen is always black. i also tried connecting an external screen with HDMI but nothing happens, all black.
I don't know what to do, someone can help me?
