First try to reset the BIOS, you may remove the cell cattery first, then press the power button to draw all the power, and put the cell battery back to see you can boot up the laptop or not.

If you can't, read the linker for more info: https://www.techwalla.com/articles/how-to-reset-the-bios-on-a-laptop

If you still have problem, try to re-flash the bios again. Make sure you re-down the BIOS.
