I meant is the Caps lock light flashing when the laptop stalls with the HP logo on the screen?
You don't have to touch anything.
If the laptop isn't passing POST (power on self test) then the Caps lock light will hopefully flash a code indicating what's wrong.
If it is not flashing you may be able to check the hardware by using the HP PC Hardware Diagnostics UEFI test. See if you can test from either the Hard drive or the BIOS options
Here's the [http://h10032.www1.hp.com/ctg/Manual/c06172090|manual] for your model. (HP Pavilion x360 m Convertible 14m-dy0013dx)
Go to p.79 and follow the procedure and see if the diagnostic tests are located in either the hard drive or the BIOS so you can test the laptop hardware e.g. ram etc.
If not you may have to download them onto a USB drive as stated and then try it.
