Hi,
I am unable to see your image right now but I'll guide you to fix this.

First of all start another bios setup and create recovery USB using it.
Now terminate the current setup and boot into your recovery USB.

Now you have updated your bios successfully:)
Please make sure that you download the fully compatible version of bios before proceeding.

Did you created bios recovery USB as i told you?
Boot into bios recovery USB.
Just plug in the USB and wait for system to recover itself

If you not created it then create it from another pc.

No do not press any button just plug in and power on your notebook.
Your system may restart several times during this process.

Do hard reset and try again
Shut down your notebook and remove battery.
Press and hold power button for 15-30 seconds.
Replace the battery and try to recover the bios.

I have tried hard reset without removing the battery. I have pressed down the power button for 15-30 sec then released it. Didn't seem like anything happened other than just turning on the power button light and then turning it off. Then i plugged the ac and turned it on. But the same thing happens. 2 long 2 short beeps
