I tried to reset the CMOS according to the instructions on the link, but unfortunately it did not help. The computer is still just beeping and won't start. Are there also pin-s on the motherboard somewhere to reset the CMOS on the J50c-4? I have not found them. I just removed the battery and waited, but this does not seem to reset the CMOS.
Have you added your own RAM or removed & reinstalled the original RAM to the device?

If you added your own, try removing it & put the stock back in to see what happens. Otherwise, try removing the RAM & re-seating it.

Any change?

5. Choose the USB option and "Enter", then you'll see 3.jpg. The UEFI will go to "GML0B015" folder of your USB automatically.

6. Type "ls" or "dir" command to make sure the BIOS files are there, which are "GML0B015.BIN" and "AfuEfix64.efi". (See 4.See_if_BIOS_files_are_present.jpg)

7. Run the "update.nsh" file to update the BIOS. (See 5.Update_BIOS.jpg)
Warning: Do not unplug the power supply when flashing the BIOS. Must not unplug until the BIOS flashing process has been completed.

8. When it wants you to choose one option, please choose "E". (See 6.Choose_'E'_to_proceed.png)

9. When the BIOS is updated successfully, it will automatically restart the Windows 10 OS.

10. Remove the USB stick. Everything is now finished.

When you go to the BIOS again, you can see the "Project Version" is now "GML0B 0.15 x64".

IMPORTANT WARNING: After upgrading the BIOS to 0.15, please DO NOT downgrade the BIOS to a lower version. Otherwise, the BIOS chip will be broken down.
