This Compaq is not manufactured by HP. It is a Chinese model renamed with the brand. Like Gateway USA... but this is a Compaq Argentina.

Yes, I know, this model is a Compaq Chinese Generic, i try bios dump from Telegram Bios Archive and boot, display on hdmi but not on display onboard. I need unlock bios password of the bios uploaded then i can disable secure boot and install SO. Thanks.

Can you post the EC backup

[nicohd87]

I didn't read the ec, only the main. I don't have tweezers, I would have to lift the IC and I don't want to manipulate the equipment too much.

What part number is the EC chip. Does it have an external EC rom chip or can it be programmed through the keboard connector or JTAG .
