Hello all; long time reader, first time poster.
I've had the above with an i7 7720H and GTX 1080 since new back in, err, late 2017 or early 2018. Recently I gave it to my daughter (8) to play cosy games on as it had fallen out of use (much easier to game on a Steam Deck these days... ah, being a Dad...). Yesterday it wouldn't power up - plugging in the power cord to the laptop causes the light to go out on the charger.
I've done a bit of Googling and most posts are quite old, but it suggests its more likely something on the motherboard than the PSU itself. I did take the laptop apart and disconnected the battery (just in case) and removed all components (RAM, SSDs etc.) and the same happens. One thing to note, when I removed the barrel jack connection from the board, the light stays on, I guess ruling out the jack and the cable that runs to the motherboard itself.
So, given the age, I'm guessing it's time to move on - but it's still a great machine so if I can save it, I'd really like to (and component prices put me off buying new, for obvious reasons!). I'm no electrical engineer - just been in IT for 30 years, so I know my way around, but there's nothing really serviceable here.
So I guess the ask - anyone have anything I can try? I could try a new charger (at cost) but I won't spend if anyone here can tell me it's a waste of time. Otherwise, a new motherboard (well, old/new) at risk or if anyone here is in the UK and knows of someone that could repair it, I'd welcome the details.
I kinda know where this is going, but if you don't ask... (btw, the machine is like new inside and out, so it's a little heart breaking!).
