So I was on the desktop listening to some music, then I started photoshop and poof, it instantly died. Now it won't start, whenever I press the power button the charge led blinks white, and there is some kind of electrical sound coming from inside the laptop. I`ve tried different power adapters, taking out ram, nothing works, any ideas ?

Need to check and repair pcb inside of notebook- some elements is malfunction.

Where would I start ? It's worth mentioning I spilled some liquid on it a few years ago, but I closed it instantly, took the whole thing apart and let everything dry for a few days. It's been working fine since then, until the other day ...
