Laptop won't start

[Dave_1959]

HP Envy x360 Convertible 15 ds0502na

Laptop was fine last night now won't start

Power light on.

Have tried 15 second power button hold, briefly came on, then blank again. Retried - nothing (No accessible battery to remove). Power light red whilst holding power button. When power reconnected 

Have tried Window-B-Power for 2 seconds, release power and wait, nothing.

Power light alternating white and red at this point. Now solid white again.

Any advice appreciated

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 outside the U.S., here is a link to HP Service Centers, by Country/Region: https://support.hp.com/in-en/service-center

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

Thanks for replying. Confirmed what i was thinking, but thought I'd ask the question first.

We'll try the retailer first, although it was a reconditioned one, and failing that we have some local repair shops to try before we go nuclear on it!

Many thansk again
