Does anyone know how to run from AC adapter without battery?

I've managed to open the notebook, disconnect the battery with the mainboard. Then I plug the adapter in and press power button, but nothing happens. *The reason I want to do this is because the battery is very unstable in my G751. Sometimes it will charge, and sometimes it won't. Left it cool overnight doesn't help. Sometimes I get it work by unplug/replug AC adapter many times.

Some more infos:

- I dual boot for both gaming and work (Windows and Linux respectively). If I only boot into Linux, it never has any problem. I think that is because it doesn't require a lot of processing and the machine stays cooler.

- Sometimes I boot into Window to play games. Most of the time there won't be any problem. But sometimes, after some gaming (I guess it becomes hotter), the "green light" will change to "orange" (or red) as if I have disconnected the adapter. No matter what I do, I can't charge it anymore. So the only way is to continue gaming with a bad performance (lower fps) until the battery goes so low that the computer shutdowns.

- Next, to be able to use the computer, I do the "plug/unplug" thing and pray that it works. It works here means the light will be orange (saying that the battery is being charged). This is the most interesting part though: if I don't wait for the light to becomes green (means 100% battery) and turn on the laptop, the light will disappear and the battery won't charge anymore.*If I wait long enough, I can use it normally like before.

Sorry if my English is hard to understand! Thank you!

Hi,

you know the laptop will not charge until its below a certain level (95% in standard configuration).

Hi,

Thanks! Yes I know this from reading other threads too. My situation is that it won't charge, even when battery go down to 1%.

At this point, I cannot use it anymore. The only solution is to plug/unplug and pray that it will charge.

Stupid question - do you have the right charger? Sounds like you cannot provide enough power while doing high power consuming stuff?
Second question - can you ensure you dont have a broken cable?

1. Yes, it's still the same ASUS charger.
2. Yes, sure no broken cable. I thought it was the charger before, but this is surely something to do with battery/power of the machine.*See my edited post: when I wait long enough for the battery to become 100%, and after that if I only boot into Linux to work, there won't be any problem for a long time (the charger doesn't get disconnected).*It only gets disconnect and stays disconnected after one unlucky gaming session. After that is my "plug/unplug" journey.
