I have had this computer less than 1 year. HAve not done any upgrades or mods. I first noticed this about a week ago. I tried holding the power button off and resetting it per the IT team with asus. I tried doingthis with the AC cord unplugged as well didn't make a difference. I Tried uninstalling the battery"drivers". Nothing. I am not sure what to do next. I Am not confident in asus tech support that doesn't speak very good English and let alone barely understand that. Suggestions?

You need to re-calibrate your battery, so you need to drain your battery all the way to 0% and then try charging to full then drain again all the way to 0%. When I say you need to drain your battery completely, I mean you really need to drain it completely. Most of the newer laptops have SS USB ports that can still charge your device after the laptop is powered off. What I do is connect my phone to the laptop and I drain every tiny bit of power from the battery. My laptop could only charge to 95% and I used this method 3 times (rinse and repeat) and afterwards the battery was back to normal and could charge to 100%.

Hi
I have the same problem with my G751JT and after talking with asus support they told me this:
"""
Thank you for contacting ASUS Customer Service.
My name is Carter and it is my pleasure to help you with your problem.

I feel sincerely sorry for your trouble.
I understand you are meeting the battery issue with this product.

If the issue appears after you have installed some software or hardware, please uninstall or remove them and check if it is helpful.
Then please load BIOS default as follows. Please turn on the laptop. Press F2 as soon as you see ASUS logo to enter BIOS. Then press F9 to load BIOS default. Then save and exit and then reboot the laptop.
If still, please get to the Control Panel -> Power Option -> Build the Power Plan -> Select the High Performance mode and try again.
Also if convenient, please connect the AC Adapter to different power Outlets in your home or office for a further test.

If no effort, I am afraid that the internal battery seems to be failed.

In this situation, I would suggest you to send the notebook to our RMA department for further test and repairing.
''''''''''''''''''
I did everything they said and had to send it to RMA today.

Let me know what they say? I am assuming part of the battery is fried.

looks like you have at least 2 problems in battery
1. FULL CHARGE CAPACITY 45,885 mWh: it is 51% of the designed capacity 90000mWh, wear level is 51%, pretty bad for a laptop less than 1 year if no absue
2. 85% charge: 1 out of 8 cell probably s dead

it seems G751 might have quality issue on battery, that's why I started this thread after reading many bad battery stories
