notebook HP 14, Odd power issue

[Krakio]

I have an odd issue with a hp 14 r008la notebook when powering on. If you could give me a hand I will appreciate it.

 

To power it on I have to:

1. Press and hold power button
2. Plug in wall charger
3. Release power after 10 seconds.

Keep in mind it doesn’t turn on if I leave the wall charger plugged in overnight, if I do it won’t start until the next day. The notebook won’t work with battery or while its plugged in.

 

I have tried:

1. Different power brick 
2. A new, charged battery
3. Unplugging and plugging back ram
4. Opened and checked for water damage, non-visible.
5. Unplugged, mouse pad, keyboard, wifi module, hdd, display

 

I believe this may be caused by some component on the board but I don’t know where to start checking.

 

Thank you in advance.

Yeah if you've tried unplugging stuff and nothing works the motherboard might be fried. If you can try looking for a new one. There's not much you can really do unless it's a detachable component, try different ram slots if you haven't already. Also maybe check if the wires or connectors for the battery are corroded or broken.
