Laptop turns off mid-use out of nowhere without warning

[GoofyFella]

So I was just using my laptop normally until it suddenly just turned off out of nowhere. I'm not sure if I heard right but I think I heard a click sound happen right as the laptop shut down, is there any solutions where I don't have to open the laptop to fix it, if not just tell me what to do if I have to open it, just so you know,when plugin the charger in, the light turns on, but the laptop refuses to boot up and Ive tried all the reset methods I know or have seen. I'm new to this kind of stuff so anyone's help is greatly appreciated

Edit:I realized that the light indicator for charging is blinking as well

Welcome to the HP Forum.

What you have described sounds like a possible MB: power rail issue or component failure.

You're probably going to need HP Warranty service if your PC is in warranty. HP would probably replace the MB if your PC has a MB problem.

Or you would have to find a local qualified PC Electronics Tech.

Have you tried to start the PC without the AC power brick?

You could then try removing the Lithium-ion battery to reset CMOS but that's about all I can think of.

Try to start the PC using AC power without the battery installed.

There would be no other reason I can think of for you to disassemble the Laptop.
