Chosen Solution
So I bought an Asus ROG G751JT 8 months ago, and it’s been fine up until last month, when it stopped charging plugged into the power cord (The green battery charging light does not come on). Didn’t use it for a few days thinking it was bricked and would have to be sent in for repairs, but then one day it magically decided to charge again. Everything’s been good and fine up until last night, when while I was using it (stationary, on a table) the brightness of my screen changed a few times, indicating the laptop switching back and forth from AC to battery power, and it is now back to not charging at all. Is the laptops power adaptor connection to blame? The cable fits snugly, but perhaps not as snugly as I would like (there is a little give to it when wiggled side to side). Really sort of bummed out that my first $1,500 foray back into Windows as resulted in a bricked computer in under a year, when my Mac has been chugging along for over 6. Any help would be really appreciated. :(
The same thing that happened to me exactly the way you described it except for the fact that the plug didn’t work it didn’t at first but I found a way to make it work and that was when I powered it up the (laptop) I hold down the delete button and play with the shift button up and down after 8 or 9 tries then the computer will see the plug but it won’t show the battery charging only for a brief moment then that stops and the computer State on I hope that helps
Definitely, try first with some other Power charger. If this is not the case then you have a problem with Power chip on your motherboard. You will have to find nearest Reair shop which is able to do a little bit of Micro soldering.
Just confirm if it’s the brick first. Got a Multi-meter? Prong the end and check if there’s any power going through. Use setting ṽ And VΩ jack + COM jack on the meter itself.
I had this problem the last couple of weeks on my Asus g750jh When playing games it started to constantly switch between battery and ac power, if I had the battery out of the unit it would just straight up crash, eventually it would stop charging the battery and the unit would not power on again randomly for hours later. I tried different power supplies, checked all the hardware inside the laptop, changed bios settings, you name it. After extensively trying to find solutions (including the problem disappearing for a week and then suddenly returning) I eventually established the problem is with the latest nVidia GTX drivers. Using cpu-z I was able to analyse the power states of the graphic card, it normally goes into “idle” power mode when not gaming. Upon inspection the card kept glitching into “pwr” mode when going from “idle” to unrestricted mode, this “pwr” mode restricts the graphic card when running from the battery. Whenever this would happen it would cut power to the ac adapter and begin a constant loop until the laptop would refuse to turn on again.. The last time this happened I immediately installed these drivers from 2015 after reading a post on another forum suggesting its a driver issue with GTX 600+ cards, and have not had a single problem since. Driver version no : 347.25 https://www.geforce.com/drivers/results/… Version 347.25 - WHQL Release Date Thu Jan 22, 2015 Operating System Windows 7 64-bit Windows 8.1 64-bit Windows 8 64-bit Windows Vista 64-bit Language English (US) File Size N/A My laptop is running better then it has been all year going back to these drivers. For anybody having these problems on an ROG with a GTX, try this solution.
I had this problem after changer one of the drives. The battery isn’t charging, as if it’s just not connected. So the battery is simply useless right now. PC works perfectly fine, I just need to plug it in to use it, which is somewhat of a bummer.
