Laptop keeps booting up then immediately switching off

[nessiedarling]

Sorry I can't get an exact product name, it doesn't say on the machine and I don't have the box, but its about 2-3 years old.

I woke up this morning and she was making this sort of breathing noise, so I had a look and it was repeatedly trying to boot itself up. The power light would switch on, the fans would make the short whirring noise they do when it turns on, but the screen would remain black (wouldn't even get to the hp logo) and it would switch itself off again. And it keeps doing this.

I can fully switch it off so that it won't try to boot up again, but when I switch it back on again it goes back to repeatedly trying to boot up. I have tried to do the windows+B thing to get a BIOS update but it didn't work because it can't stay on long enough. I've also tried repeatedly pressing the escape key as its booting up, but again, it won't stay on long enough to do anything. I also saw somewhere saying to press the power key for 30 seconds to remove static, but that didn't do anything either.

I haven't made any recent hardware or software changes, so I'm not sure what could have caused it, but if you can figure something out, thank you so much! 🙂

If it is possible, to find out the problem, you would need to be able run hardware diagnostics by pressing the Esc key repeatedly and then, when the HP Startup Menu appears, select Diagnostics (usually F2) and let it run.

If it is NOT possible, 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.

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.

--------------------
If your PC is still under the original one-year HP warranty, or if you have purchased an extended warranty from HP and this is still valid, then having HP do this is an inexpensive option for you. In that case, you should contact HP Customer Support to see about having it repaired or replaced under warranty.

To contact HP Support see the following link to create yourself a case number, then call and it may help speed up the call process:

Step 1. Here is the link: https://support.hp.com/us-en/contact-hp
Step 2. Enter Product number or select to auto detect
Step 3. Scroll down to "Still need help? Complete the form to select your contact options"
Step 4. Scroll down and click on: HP contact options - click on Get phone number

Case number and phone number appear.
--------------------
If your PC is no longer under warranty, then it will cost you up front to have HP examine your PC. If you want to do that, you will have to contact an HP Repair or Service Center to see if they can examine the PC to determine the cause(s) of the problems, if it can be repaired, and an estimate of the repair costs.

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

Good Luck
