Hi!

I have this laptop and first let's go through what happened

Went totally dead, no reaction
I thought it was the adapter so I bought a new one = nothing happened
Opened up the laptop and adjusted the battery cable = Started working
Worked a couple of days and then went totally dead again

Now nothing works

I have opened the laptop, removed basically all removable components. It does not start without the battery or harddrive or anything disconnected.

Testing with voltmeter I can see 5.3V basically everywhere inside the laptop. I was watching a YT video about MOSFET but seems everything is getting power. Even the power indicator light has power but never lights up

What can I more test?

Thanks
