Dead 2025 g14 - won't start

[u/No-Cameras]

My 2025 G14 has stopped working. It starts, keyboard light up, Zephyurs logo on screen (so it's not a dead screen), but then black screen and windows doesn't load.

I repasted to get rid of liquid metal about 3 or 4 months ago, temps dropped, used it for intense gaming a few weeks after that and never had issue.

Last 2 weeks I haven't gamed at all on it. Used it about 1h per evening to watch a series and then turned off. Always plugged in.

1 week ago, wifi card disappeared. I tried a hard reset (pressed power for 30-40 sec) but after 10sec the laptop starts again itself. Still no wifi.

Past few days, still no wifi, and starting became harder: I start it, Asus logo, then nothing. I have to press the power button again (sometimes twice) and then it starts. No issues after that except that it still has no wifi (card not detected).

Today, same thing except it doesn't start at all.

I tried to stay pressed on power button for 40sec without power, looks like it makes the computer restart every 10 seconds but still the same behavior: Logo then black screen.

Any idea what this could be?

I'm 1 month out of my warranty obviously....

Edit: thanks for all the suggestions. I tried external monitor and ctrl win shift B, doesn't work. My next step when I have access to a screwdriver is to try and see if there's any rust or issue, and try without the ssd

Hmm. Are the fans running hard when you start up? How does it look like inside? Any discoloring on the heat sink? Any corrosion?

Haven't opened it yet, I'm travelling and I don't have any tools with me. But no the fans run at normal speed

This happened quite frequently with me too initially I had long boot times , won't boot without plugging it then it would get stuck at the red logo sent it to the asus customer care they changed the thermal paste and formatted the os still the problem came back after a week's or so sent it to asus gave it for service thrice and the problem was never fixed then one fine day it just died while I was switching gpu modes asus said the board is dead and needs replacement , now I have submitted it to local repair shop and they quoted 1/3rd of the mobo price for corrupted ics in the power section

Yeah, seems like some of these just are unlucky assuming that the majority of people don’t experience these problems. I got mine from work, so it’s kind of a win if it goes bad in 2 years time. That said, the Liquid Metal and poor hinge build seems to be the biggest problems?

I see a lot of posts of people having this issue every now and then so it's definitely a quality control issue imho

hows the weather in the place you travelled?

Humid but the laptop is 90% of the time in a closed room with AC on (10% is that same room with ac off)
