So, I was updating my bios but for some reason my laptop suddenly turned off.

Now when I try to turn on my laptop, I can only see the dell logo. I have been trying everything to access the BIOS menu, like pressing CTRL + ESQ then connecting the power cord, pressing F12, F2, but nothing happens. The only response I receive from the laptop, is that when I press ESQ + CTRL and I connect the power cord, I turn on without me having to press the power button.

I also had tried to remove battery and coin while pressing the on button for 15 minutes, I also had tried to turn on the laptop without the SSD and nothing.

Have I hard bricked my laptop?

Please help me to recover from this disaster. 

I got a latitude 7400 2 in 2
