ah yes, that is exactly the thread i saw!

Because when I game, I notice the center LED light change from white to orange meaning my laptop is charging, which means the power adapter isn't enough and therefore the battery is also discharging to keep up with the hardware. This also means when I hover on the battery icon on the taskbar, it says "plugged in, discharging".

Based on the thread you linked, is it enough to just get a different power adapter that provides higher watts but same voltage? I saw another thread here saying you might need a BIOS configuration to actually allow the higher wattage to come through so I was wondering if that's the case for the GM501

Welcome to the forums!

Please check your battery charge level too since it's normal for the battery to stop charging when the level is 95% and above as mentioned in the FAQ below.

If you're saying it's normal for battery to discharge by at most 10% in the short span I do gaming, then that's quite telling of bad hardware. I just needed to know if I'm being provided enough by my 180 watt adapter, not how batteries work. And if it isn't enough, is the solution as simple as getting a new adapter or is there a necessary BIOS change as I have quoted from the link of another thread in my earlier post

You didn't mention how much the battery was discharging earlier, so just wanted to make sure you were not seeing the normal discharge to 95% common on all our current notebook models.

Sounds like your model may support battery health charging though which allows discharging less than 95% if you choose, so check if this utility is installed in your system and adjust the settings if necessary.

Below is an FAQ and video from our website if you're interested. Thanks.

Hi I have an Asus Zephyrus gx501 with the gtx1080 and I also struggled with discharging battery during gaming, I discovered that capping games to under 80FPS worked for me and stopped discharging battery!!! But this defeats the object of the 144hz GSYNC Screen, so I went to device manager and disabled the "AC power adapter driver" and since then i can play games full graphics and resolution at 144 fps with no discharge.

UPDATE: this works best when
STEP 1 Disable the ac power adapter driver,
STEP 2. charge the laptop to 100%,
STEP 3. using the "ASUS battery health charging tool" set it to maximum battery life mode (the 60% charge one)

DONE 😄 as long as your laptop is plugged in it should stay pretty much fully charged from here unless its put under extreme stress for a Long time.

I hope this helps many people like it helped me.
