Lenovo laptop is dead, how do I test to find whats wrong?

[nachoi]

Hi guys, I've been reading the forum for years and now I need help myself.
I have a Lenovo Flex 2 14" S/N WB15534056 that doesn't turn on (100% dead, not even the charging light).
A few days ago this happened, I unplugged the battery, pushed the power button a few times, plugged it again and it worked... until now.
Now it's dead and my battery trick doesn't work, how should I test it?
Things I've tried:
- Replacing the RAM
- Checking the AC power adapter (20.9V)
- Replaced the CMOS battery

Thanks!

Does it react to mains power if the battery is left out completely? A battery could be so worn out it can't even allow power through itself.

No, it doesn't.. Same thing 🙁

It's possible the power jack inside the case has failed and the battery finally ran out of power. How does it feel when you put the plug in?

The jack is fine, I've tested it (measured the voltage on the board). I don't know what else to try

Strange that it doesnt power on despite the board being powered when plugged it.

If the CPU is one of the removeable varierty, it's got to be worth reseating it and applying some new thermal paste.

You seem to know your stuff so I'm sure you don't need me to tell you now delicate and risky a process that can be but for the benefit of future readers - don't try this at home, folks!

The processor is soldered, I think I will send the motherboard to a repair shop (since I can't get a replacement). Any recommendations?

You should be able to walk into any PC repair shop and get what you need because the US is well served with parts shops..

In other countries much South of Florida would be a different matter - hahaha!

hahaha, I know..

The thing is that this laptop was bought in Austria and this specific model doesn't exist in the US.. I already asked an official lenovo repair shop and they told me they can't get the part..
