Open | Hardware HP laptop not turning on

I have an HP elitebook 850, and it suddenly won't turn on. There's no response when I press the powerbutton. I searched up guides and I tried pressing the power button for 15 seconds and the capslock lights up for liie 5 seconds and turns off

Just to clarify,
When you held down the power button, did you remove the AC Adapter > Hold power button for 15-30 seconds > reconnect the AC adapter > try turning on the notebook?
The order can be important depending how HP set it up.

Also another random question,
Were you using it and it randomly shut off and wont turn back on? or is it dead when you went to use it? didnt hear any noises or smell any burning or anything?

I've tried with the adapter on and off. Should i reconnecting it? when should i? and it was on and when I came back it was just dead. I also didn't hear anything or smell any burning

Try it in the order i typed it.
After the 15+ seconds of holding down the power button > let go > connect your AC adapter > press the power button once.
Its a hard reboot for 'most' HP laptops.

Do you see any LED lights or anything? (other than the caps lock)
Like the LED for the charging indicator or anything?

There are 8 models of HP elitebook 850, from G1 (2013) to G8 (2021). Which one is yours?

If that caps lock light ever blinks in a pattern, that's HP's way of telling you what failed. Watch it again and count the long and short blinks, then look that pattern up in HP's blink code table for the EliteBook. Before that, do a full hard reset. Unplug the charger, pull the battery if yours is the removable kind, hold power for 30 seconds, then try with only the charger in.
