HP Probook 650 g4

A relative has bought a used laptop online and has asked me to check if I can remove the messages that appear when starting the laptop.

The following two messages appear

- Your system is not fully configured. Please contat HP customer support
-This BIOS is not for Production Use


I have tried to update the bios but it gives error. The bios version is Ver 80.31.00.

Thanks.

Re: HP ProBook 650 G4

attached is a picture of the motherboard, and the label is
CHROMIA-60650A2930001-MB-A01(A1)
You can see on the board where I was trying to remove one chip it said winboard, but I'm not sure if that's it.

Re: HP ProBook 650 G4

my main problem is that you were locked to me :/

Re: HP ProBook 650 G4

my programmer is not good enough for this chip and i can't read it. I use EZP2019, can you recommend another better one so I can order for Bosnia?

Hello, my device is having an error. The problem is that after 10 minutes of use, the device automatically resets. This is my old bios backup, please help me fix it.

Help me with BIOS on 650 G4 motherboard CHROMIA-6050A2930001-MB-A01(A1)

In my old one there is a black screen and gradually the fan turns at maximum speed

I'll add to my post above. I flashed the laptop with a set of EC and MAIN bios from post No. 6. The laptop began to turn on, which indicates that the hardware is completely working. But when you turn it on, the fan starts turning at full speed, then it stops and works normally. It also takes a long time to turn on, the screen is dark for about 40 seconds. This is understandable, since the BIOS is from another laptop. I can't collect a working dump from my original and the update from the site. Please help me. 2 original bios in the archive.

Thanks, the BIOS works.


But when turned on, it shows the message "HP Endpoint Security Controller Problem"
I don't know the password on the old original BIOS, the laptop wouldn't turn on.

I corrected the error, flashed my original EC, and 32MB BIOS from hoaca388, for which many thanks to him!
