Bootsup to Black Screen and then--nothing

[GarretPI]

FYI, I went through all troubleshooting steps in this article: https://support.hp.com/in-en/document/c01997899

Repeatedly.

I did a hard reset, several times.

I tried connecting to an external monitor. No signal.

I was unable to either recover or update the BIOS. No BIOS screen ever appeared despite trying powering up while holding "windows key B" and then continuing to hold "windows key B" for up to 40 seconds,  and then trying "Esc" repeatedly and the trying "Esc" followed by "F10".

I reseated the memory chips. (And had one heck of a time getting the darn laptop open to do so!)

I even tried a chat session where the poor sap on the other end had to follow his/her script and asked me to start from the beginning with a hard reset. I was so out of sorts by that time, that he/she felt compelled to abandon the chat session. Wimps. And then I was sent a fake code to reconnect, which the HP website promptly told me was an invalid code for LogMeIn123. Although I am unsure as to how whoever connecting to my other computer would in any solve my issues with the laptop.

Regardless, I have a paperweight, with no apparent way to fix it and turn it back into a functioning laptop.

Now what? Anyone know how to get a refund?

@GarretPI 

Let's deal with your last issue first -- HP does not provide refunds for used equipment, so you can forget that option.

Sorry for the bad news, but when a laptop does not even power on, you have few if any options for getting it working again on your own.

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.

But if it is NOT possible to run diagnostics, then there is NOTHING more you can do by yourself -- and there is NOTHING we can do.

You will need to have the PC physically examined in a service facility by folks that can run their own diagnostics to determine what is wrong with it. And the problem with that is, while HP does do repair work of some sorts on PCs still under warranty, they generally do NOT do repair work on PCs out of warranty because they are not a general purpose repair facility. You would have to contact them in advance to see (1) if they are willing to work on it, and (2) if they will provide you any kind of repair cost estimate.

Since you live in the U.S., here is a link to the HP Service Repair Centers:
https://www.service-center-locator.com/hp-hewlett-packard/hp-hewlett-packard-service-center.htm

If that link does not get you a useful page, then use the main HP link:

If you can't get assistance from HP, then you will have to seek out a local laptop service facility to have them examine it for you.

Good Luck
