I can't identify the laptop model

[Joe_Shadow]

Hello everyone!

I got a laptop, an HP ProBook, from the used market, and I was very surprised that there was no serial number on it. The laptop was repaired, the Bios was flashed on it, and after that the touch screen and discrete graphics stopped working on the laptop. I decided to find the Bios for this laptop, and I met with such a problem that I can't determine the exact model of the laptop. I can't contact support, because I need a serial number, which is not on the laptop.

Here I ask you, great forum super minds, to help me identify an unknown device. Here are all the photos of what the device looks like.

Sorry for the crooked photos, because I'm not a photographer (Don't scold me, that's what I wanted to convey by this). I think you can help me.

Hi:

Go into the BIOS setup (ESC + F10) and you should see the model number of the PC listed there (system information), or at least the product number and serial number.

From that, you will be able to determine the model number.

The bios has been overwritten, and when the computer boots, it requires you to configure the bios (To be more precise, the laptop requires you to keep all serial numbers, track numbers, barcodes, name, feature byte and build ID). If it were that simple, I wouldn't ask you what the laptop model is.

I'm not a mind reader.

I have no idea what things you tried before you posted your question.

If you can't get into windows or can't even identify what model processor the notebook you have comes with, no one here will be able to help you.

How can you help me with the information that I will send you in the photo?

Looking at your screenshot and the BIOS version of 1.21, and the other pictures you posted, I believe your notebook is a HP Probook 640 G2.

Here is the link to the HP Quickspecs for the model series.

The processor in your screenshot has no description, but the above specs show two processors that are 2.6 GHz.

Intel® Core™ i7-6600U

Intel® Core™ i5-6440HQ

Here is the link to the support page with the various manuals and guides, software and drivers.

When you look at chapter 2 of the service manual, the various items on all sides (top, bottom, left, right, front, back) of the notebook seem to line up with your pictures.

You model does not have the optional left and right pointing stick buttons as shown in chapter 2 on page 10.

Hope that helps.
