Press any key to keep it on

Good evening,
As you may have gathered from this brief title, my Acer laptop has a slight problem..
To summarize the situation, I spilled a few drops of water on the machine a few days ago while it was working perfectly. Unfortunately, it stopped functioning (rather suspiciously, as this was clearly not the first time it had happened and I had never experienced any issues before) and wouldn't turn back on.
This morning, I tried turning on the laptop again and realized that the loading screen came up, but then the laptop would shut off after a few seconds with a small "click" (the same sound as when it is turned off 'forcefully'). Instinctively, I tried to turn it on while pressing the keys on the keyboard at the same time..
And it worked! In fact, the laptop runs fine as long as I keep pressing a key, otherwise it shuts off. I tried using tape, but it's not reliable or practical...

So I'm asking for your help, or at least an explanation. Thank you in advance to those who will respond..
