I just wanted to give you an update about the laptop.
So the repair shop couldn't do anything, as expected. They had the same problem as me and the person taking a look into it was frustrated same as me and after 4 days, nothing happened. They are a great repair shop, but just, they couldn't do anything, so they returned the laptop and didn't charge me a thing so... Yeah.
Just not working still, behaves the same.
PS: I will try and replace the CMOS battery, but, this is a desperate attempt.
