External Battery Pack

If your notebook has an external battery, proceed as follows:
1- Unplug the appliance from the mains and then disconnect the battery.
2- Press the power button for thirty seconds, so that the static power is dissipated.
3 - Replace the battery and turn the unit on.

Process for calibrating the battery

For this, you must turn off the device and give a 100% charge.
Then unplug and use the battery until the battery runs out.
Reload it as before.
Repeat the process 3 times so that all cells are fully calibrated.


POWER INTERRUPT BUTTON

You can either press the right screw a little more or put some layers of electrical tape:

@SHOW as it was already said above by @MaClane and @egydiocoelho that is completely normal the battery will only start to charge again on A/C (when gaming etc) when it drops under 40% and when it does you will suffer a hudge drop in performance if you are playing any game or any high demanding task as the adapter cannot provide enough power to charge the battery and for that task at the same time so my suggestion when that happens stop what you are doing and let it charge to 100% in fact never play any games or demanding tasks on battery and when playing make sure the battery its always 100% charger before you start

@SHOW the gtx 1050ti variant brings the 135W the 1060 the 180W adapter my 135 never had any issues with it also you have to consider that by using high powered usb devices will force the adapter to drain power from tha battery as this one cannot provide enough for ex tere are ppl using usb non powered hubs those are just rubbish they will drain all the power you will loose performance and battery always use powered hubs and if you are one of those i recommend Anker my battery never drained even a bit while gaming 10h+ non stop now i noticed it drains a bit (not much i dont even notice) because i have an external 10gbps 2.5" usb3.0/3.1 with a 5tb 2.5" hdd always connected

FillInTheBlank this is not a bug its a feature (i really cant understand why ppl call bugs to every feature designed/tested by the engineers just because they dont understand it or like it oh well) the predator gaming laptops will not charge while gaming unless the battery reaches less than 40% you will notice that you will loose all performance when this happens the adapter cannot do both you have to stop what you are doing and let it recharge to 100% also never play on battery if you do so you will end up by damaging the cell sooner and the battery will die due to too much wear and when playing on AC make sure the battery its fully charged before you start any game

The battery main purpose on gaming laptops its to aid the adapter with extra power when this one cannot provide enough to the cpu/gpu nothing else as i said only use it ion battery on emergency or if you dont really have a socket near and only for really light works apart form that keep it always on AC all the time
