Hi all, I made a thread about this in the past but the problem has precipitously worsened since then. In the fall of 2018 my Rog G751JT would disconnect from AC power while gaming. My event viewer would be littered with 'power source' change notifications and gaming on AC was impossible because eventually the laptop would stop recognizing the adapter no matter what I did.
The "good" part about this issue was that it was only limited to high intensity gaming. I still had a usable laptop for low end/low intensity games, watching streams, Netflix, etc. While this was still an annoying problem given I bought this laptop for higher end gaming, I didn't do much to troubleshoot the problem and just used it as a 'regular' laptop to at least feel like I got some of my moneys worth out of it. It was already out of warranty and I couldn't find anywhere to send it or get a price for what it would take to cost to fix - and honestly reading the horror stories of it being sent to ASUS and STILL not fixed had me wondering if it was worth bothering with at all..so I didn't.
However this past week the laptop started dropping its connection to the adapter under idle/light loads. Now as of last night, it won't recognize the charger at all...even off.
There are 3 likely culprits at play here, according to my research this is a notorious issue with these laptops:
The DC jack itself is broken.
The adapter is bad.
The battery is bad.
I do not think the battery would be bad - it is only at 3 percent wear level according to HWMonitor, though I do not know what that exactly entails. But the laptop has always been plugged in since I bought it in 2016. It was used for gaming with mobility being an afterthought, so the battery should theoretically be in impeccable health. Could it still have gone bad despite never being used or taxed?
The adapter could be the issue, but many posts I have read said that the adapter being replaced did nothing to rectify the issue. To compound to that problem, the OEM adapter for this model are not cheap. There are cheaper 3rd party models on Ebay, but I have not tested any new adapter out.
The DC replacement actually seems like by far the cheapest fix despite being one of the more technically challenging problems (anyone can replace an adapter but cracking open a laptop is always an adventure).
What is my recourse here? When the laptop is properly getting powered, it is still as fast as it was day 1. It still runs games at high FPS, and none of its components seem to be even remotely damaged or compromised in any way. Literally the only problem is the AC power...but obviously that is a big enough problem to render the computer completely useless.
Is it worth looking into fixing this? I love this laptop. Would it be worth sending it into Asus? What would the likely cost to fix it be? Are there any other possible culprits? I have found DOZENS of threads pertaining to this issue.
I will say I am likely going to be buying a Strix Scar series laptop soon, so cracking this laptop open and fixing it as a side project could be fun since it will no longer be my only laptop. I'd love to salvage this laptop because it is an amazing machine when working and still has relevant components three years after purchase. I just didn't want to sink money into it if it is a lost cause. Sadly it has no resale value (the working units still fetch a pretty decent price on Ebay) due to its issues and I'd never knowingly sell an item that has issues.
I would love to fix it though, and am willing to spend money to do so. Any advice would be greatly appreciated.
