Laptop is getting hanged

[ZubayerTanvir]

I am facing problem with this product from the day I purchased it. Problem is when it connected to wifi connection  it suddenly it hanged/freezes and I had to force shut down by holding power button for 5 sec. I have faced 10-12 times a day from day 1. I am again saying it happens suddenly so there is no way to check it up where is the problem but one thing I am ensuring you it happened only on connected with wifi....

Tap esc + f2 to enter diagnostic mode. Run the test on the wireless card and see if any errors pop up. Likely answer is a bad wireless card or perhaps a driver problem but let's exclude hardware first.

how to go in diagnostic mode?

First sentence of my post:

Tap esc + f2 to enter diagnostic mode.

Turn it on, immediately tap esc...menu comes up, choose f2 and enter diagnostic mode.

It will take a bit for the image to pass the censors

Try installing the latest UEFI diagnostics...should add more testing options:

it asks me to create a uefi partition named hp_tools and my windows is unable to do that because it already have 4 partition. So it said in can not be installed

You should have the option to put it on a bootable usb stick and run the diagnostics from there.
