HP cpu won't turn on. When pressed, the on button lights up for a second and then goes out.

I installed windows 10 on my older HP Pavilion last year.  Worked fine until two weeks ago.  I tried to turn it on but the on button simply blinks and then goes out.

I read the previous comments in the forum regarding this issue. Unfortunately all the links provided by the HP employee are not longer available.

I unplugged everything. It still won't turn on. My printer is wireless but my keyboard is not.  Could it be a problem with the switch or the keyboard?

Thanks

First, lets get the terms straight so we're both talking about the same thing.  A "CPU" is a processor chip soldered to the motherboard in the PC.  The proper term is "Desktop" -- indicating the whole PC.

Second, I'm not familiar with the switch in the keyboard.  I've seen them on wireless keyboards and they are used to turn off the keyboard when not in use to conserve battery life.  One in a wired keyboard does not make sense for that purpose, so it MIGHT be used to power on the PC -- but I don't know.  You should try it in both positions to see what happens.

If the Desktop still does not turn 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, or if that does not work, 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 service facility to have them examine it for you.

Good Luck
