Short DST check failed

[Jangojohnson]

I did a short DST check on my laptop and it failed. What does it mean and how can I fix it?

Did it provide an alphanumeric failure code?

Provide the failure code and I can translate what it means.

Is your notebook still in the factory one year or paid extra care package warranty?

I see your notebook comes from the 2015 model year.

Here is the support portal web page at HP where the drivers are available.

You could actually remove the current hard disk and upgrade to a SATA-3 SSD and install the  Windows 10 Home(64-bit) OS.  Once online the OS will self activate.That would give you an amazing boost in performance.

The hard disk is out of warranty, unless you paid for a care package to extend the warranty.

Did you make a USB recovery media flash drive? If not you can make a Windows 10 installation USB flash drive and use that.

 You can download the Windows 10 media creation utility here.

The Windows license activation key is coded in the BIOS and is also on the Microsoft licensing servers, so reinstalling the OS after replacement of the hard disk is not an issue.

PU11W2-81U99A-XD7WLK-60XV03 is the code. 

I haven't made a recovery media flash drive

OK.

That is an error code 303, which is a failed hard disk.

I see your warranty has expired, so the cost of a new hard disk is going to be out of your own pocket.

You will need a SATA-3 legacy type or SSD 2.5" mobile hard disk.

You will need to create your own Windows 10 home recovery USB flash drive. The link I provided in my previous response will help you with that.  You will need to use an 8-32GB capacity USB flash drive.
