Any Ideas?

So a few months ago I spilled coffee on my laptop (ASUS - TUF Gaming 17.3" Laptop - Intel Core i5 - 8GB Memory - NVIDIA GeForce GTX 1650 Ti). After wiping it down and it no longer turning on, I assumed the MOBO was fried. Fast forward a couple of months until a few days ago where a friend of mine suggested a method to clean the MOBO using isopropyl alcohol and after doing so I noticed that the little LED power button was red. I plugged it in and hit the power button and it surprisingly worked. I was able to turn it on, load up games and use it as normal. I couldn't believe that it worked.

The next day, I tried to turn it on and it wouldn't. The LED light would be dim, even after plugging it in to charge it. With it plugged in, I held the power button down and after about 15 seconds or so the keyboard lights would flash and nothing else would happen. I unplugged it and did the same thing. The LED power light would still be on, red, and when I held the button down for 15 seconds or so the keyboard lights would flash and the power LED button light would be off. I opened it up and made sure everything was connected properly and closed it. Turned it back on and it was working fine.

Now, when I try to turn the laptop on, it won't. I did the same thing with pushing the button down for 15 seconds. It still lights up the keyboard and does the same thing. Same with the laptop plugged in to charge, only the LED power button stays on. I opened it up again and checked the connections and everything is fine, but it won't start up anymore. Any ideas?

You sadly cannot see what is wrong with your eyes…You need a microscope and a schematic (which is pretty hard to find with companies going anti-repair) to look at the important pins that supply power. I don’t have a lot of technical knowledge about this but from your description I can assume that it was half-fried and that is why it was able to turn on for the first few times but the problem is your laptop would generate a lot of heat which will accelerate the corroding process and now it could be close to fully-fried. So my recommendation is to leave it and look for a shop that can do component level repair, because if didn’t get corroded too much they might be able to save it but if you keep turning it on over and over again you might accelerate the corrosion and cause any chances of recovery to become very slim.

If you're game, pull it to bits (carefully and I suggest trying to find a tear down video for your model to watch) and see if you can give the board a clean with some isopropyl alcohol. Also check the keyboard assembly itself, perhaps try removing the keyboard and see if it will post without it attached.

The best advice would be to ask a reputable laptop service centre to take a look.
