Hello,I noticed that my laptop increases its performance while playing the Witcher 3 with both the battery and the charger plugged in at the same time. If I play with the charger plugged in alone without the battery the game lags like crazy.

I tried this in other high end games like Alan Wake at max settings and was amazed at how smooth it was, the same for this game, now I can play at Ultra Settings (without Hairwors) at a steady 60fps.

My question is, is this normal and is there a way for me to get this kind of performance while only playing with the charger plugged in without using the battery?

My specs are:

ASUS ROG G771JW

i7-4270HQ CPU @ 2.60Ghz (8 CPUs)

RAM: 16GB

Nvidia Geforce 960M with 4GB DDR5

Check your power management setting. Always use Max Proc when on battery.

It's your ROG's default setting that causes this issue.

Thanks for the quick answer but my question is: Can I get this better performance WIITHOUT using the battery?

The reason I don't want to use the battery is because of the temperature issue that harms the battery.

There are no setting to use Max Proc when power is plugged in?

you mean the max performance option in energy settings? Tried that, but didn't work.

Have a look at the advanced power settings.

There are different settings that can be changed depending on whether you're using a battery or not for example "Processor Power Management".

Look under something like this: Control Panel\All Control Panel Items\Power Options\Edit Plan Settings\Change advanced power settings

If it's the GPU clock dropping in this situation, the power options are unlikely to help. I'd suggest that you try something like MSI Afterburner to take a look at GPU performance and possibly change it. I hope it works with the 960M but can't be sure.

You may give Process Lasso a try. Using it with my laptop for years. I think in free version you have to set power profiles or gaming mode manually, but that shouldn't be a problem.

It sounds like an odd case, because I presume the same "plugged in"-power setting should apply as long as you are plugged in, regardless if the battery is attached or detached. In his case, detaching the battery somehow decreases the performance, which doesn't make sense to me. Unless, for some reason, in his case it is the battery power profile that always kicks in when the battery in attached, even if he is plugged in at the same time (and the battery power profile has higher performance settings, which is unusual though).

Just thinking about this as I also have the battery detached normally on my ASUS ROG gaming laptop, I see no reason to constantly charge it if I am not using it. I attach it only if I ever take the laptop with me outside the house.

In e.g. Thailand where there can be power breaks and such, keeping the battery attached all the time makes sense as then your PC will not be powered down on those breaks; an external battery is even better, also taking care of any spikes which may be harmful to the computer.
