Bios help needed

[ahmadaliirfan32]

i was installing a bios update to dell latitude E5420. I had a power cut due to which the bios updating was interrupted now the screen is black my laptop doesn't turn on. When the AC adapter is connected the power button turns on by itself and the screen doesn't show anything. What should i do now.

If under warranty, try RMA-ing the laptop. If not, try contacting Dell and see what options available.
