Hi! Friend! I have HP ProBook 450 G2. Product: L8A66E#ACB

it is not possible to enter the BIOS. It displays the following messages on the screen: when loading on a black background for a few seconds 1) Warning !! - Machine is not in committed state! and then on a white background constantly shows 2) Broadwell Platform Not Supported. Platform incompatible (999).

the laptop starts to work when the battery or power supply is connected, without pressing the power button. To turn off must first turn off the battery and power supply.

I read the entire forum thread. I did not find such a malfunction. I cannot try the attempts described here.

I cannot try the attempts described here.

Because I can’t get into the bios. Please tell me what I'm doing wrong?
