A low-spec laptop ASUS laptop with plastic chassis.

Laptop isn't turning on neither charging

Hi, so I have this ASUS K501U laptop, that supposedly received liquid damage. Looking at the laptops insides, I could barely see liquid damage and even then not on the mainboard (both sides), only on the little board with LEDs at the bottom.

The issue is that laptop doesn't want to turn on neither charge (LEDs aren't lighting up and measuring with the multimeter doesn't show that it is charging on the battery, unless I measured wrong). I know the charger is good, because it does work fine on another laptop and I know the power jack is most likely fine because it receives full 19V without jumping around or etc.

I tried doing stuff like disconnecting the battery and holding the power button for about 30 s. but it did not help. What else I could try to revive this laptop or is it just a lost cause?

Yeah, that sounds like a motherboard problem. Using you're multimeter i'd measure some of the power rails and maybe take a look at some of the mosfets and other chips around the CPU, you never know if a part could be fried or shorting out the CPU

If it's the motherboard, I don't think I'll be messing around with it much more soon then, was hoping for maybe a quick fix, but from research and your comment, it seems like that won't be happening.

But in the future, I'll try, just as a learning experience.

@righn feel free to do so. Hope you eventually get to solving your problem (and maybe learning a thing or two about soldering in the process!)
