Does HP perform free diagnostics on computer hardware?

[GAPMan88]

I am trying to find parts for my machine in order to repair my machine with but I also want to know what parts I need. I wonder does HP perform free hardware diagnostics or do I have to take into an HP service center that can do the job for me?

IF the PC is still under the original warranty and malfunctioning, then HP will check it out as part of the warranty coverage.

But if not, then HP will not examine it as they do not do out of warranty repairs.

To determine the cause with hardware failures, you have to be able run diagnostics. We have no way of accessing your PC from here, so we can not do that for you. You have to do it yourself.

You do this by pressing the Esc key repeatedly when rebooting and then, when the HP Startup Menu appears, selecting Diagnostics (usually F2) and letting it run.

If it is NOT possible to run diagnostics, or if that does not work, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do because we have no way of accessing your PC from here to run diagnostics or repair hardware.
