Question Black screen after the BIOS update

[hack3rcon]

Hello,
The motherboard of my system is an ASUS B85-PLUS model. I updated its BIOS to the last version and when the update finished, I clicked on the OK button and the system rebooted. After that I just see a black screen. I removed the AC adapter and battery first, then pressed and kept the power button for 40 seconds. After it, I re-connected the AC adapter and battery, then turned on the system, but the problem exists. How to solve it?
Any idea welcomed.


Thank you.

Hello,
Problem solved.
I removed the AC adapter and battery for several hours, and after that I saw the POST screen.
