HP laptop abruptly turned off and will not power back on? need help pls.

HP Recommended
HP Notebook - 15-da0053wm
Microsoft Windows 10 (64-bit)

Hello everyone I'm hoping to get some help to diagnose what the problem is with my laptop. Last night while I was using the laptop it abruptly powered off, the best way I can describe it is if you were watching TV and the power cord was pulled out of the wall. That is exactly what it reminded me of. It made no noise that I could hear after it shut off, and I have not had any hardware errors pop up, blue screens or any problems what so ever with it beforehand.

 

HP 15-da0053vm, <Specs here> I have not contacted HP directly for support, I did check the SN# to see if it is under warranty, it has expired.

 

In case it matters at the time it happened - the power cord was plugged in, I was playing a game via Steam. which I've done before less than 10x and never had an issue. The HD memory on the computer is less than 25% full and specs more than adequate for the game.. After it happened when I was trying to turn it back on I felt to see if it was hot, it was not.. warm but not hot.. same for the AC adapter. No burnt smells or smoke either.

 

What I've tried so far -

Tried another outlet directly in the wall, as I'm plugged into a surge protector normally. I unplugged from the comp, and the adapter to check all was right and tight,

checked the AC adapter with a multimeter, it reads 19.44 volts input requires 19.5v. could that little a difference matter? I have tried another HP charger with exactly the same ac/dc volt, ohms, watts specs that read 19.5V on my multimeter with the same above mentioned results.

 I've tried to hold the power button down for 20 sec while unplugged, and again for 60 sec, it does nothing no lights or sounds.

When I plug the power cord in there is a constant white led light beside the power inlet, the led remains white never turns orange/amber never blinks, remains solid white light.  if I hold the power button down after 10 sec or so the white light will turn off when I release it the white light turns back on, tried this numerous times,  I have held the power button down for more than 60 sec with the same results, will not power up, does not emit any sounds, there are no other lights visible on the comp anywhere else.

The battery is built-in and not removable I have also read I could try to open the laptop to remove the battery press down the power to drain the last of the internal charge then reinstall the battery .. but would like a confirmation that from my described problem that is a viable step since it entails opening the internals of the laptop..

 

Hoping someone is already experienced with this problem or suggest further steps I can take to narrow down the cause to determine if it's something major or minor if it's fixable or worth fixing.

Thank you!!

 

I have since learned that the light should/could be orange/amber colored when plugged in to indicate charging. It remains a constant white. Could that be because the battery is 100% charged? As I did mostly use it in the same place, always plugged in.

I have also tried holding the power button down for over a minute, as suggested on a YT vid for a laptop with a built-in battery not turning on.

 

 

Thank you in advance for any info.

Hello, No i am not able to use those steps. this represents the best way to describe my problem, 

LED glows white, but the notebook fails to startup or boot, and displays a black screen, no fan, no sounds at all.

steps ive taken;

hard reset

tested AC adapter with a multimeter

tried another AC adapter known to work fine

*With ESD wriststrap on confirmed grounded*

removed the fixed battery for 1+ hr, then held down the power button for over 1 minute while battery removed to drain all power, then connected AC cord while the battery was removed and pressed the power on. (did nothing)

confirmed that there is 19.5volts at the Motherboard

inspected all connections are tight

inspected heatsink is tight

inspected all diodes to see if anything looks swollen or blown

 

Can only be a hardware problem I need the motherboard schematics to help to advise me on where and what I should test with the multimeter to eliminate or find the issue.
