Running Laptop Purely off Charging Cord

HeartFeltAxe on 04/10/2016 - 23:02

Hey OzBargainers,

I am a student who has a school "craptop" which is a laptop notorious for breaking down, screens bending, back-lighting being unresponsive ect but overall can run some games.
According to my own testing, running a game off the battery life (Without charging cable connected) is around 33% faster than playing with a charging cable connected.
Yes both power settings are set to "High Performanced" and all the settings are the same.

My guess is that somehow disabling the battery for my laptop, but keeping the laptop plugged in acting like a PC could run my games faster. And yes, it is possible I just don't know how and if it would run my games faster.

If you guys have any suggestions or help this would be greatly appreciated.
Thanks, HFX

    That's a bit different from what I'm used to seeing. Usually, with the cord plugged in, I tend to experience and expect equivalent to sometimes increased performance compared to when the laptop battery saving options kick in. Anyway your observation is mighty interesting.

    With regards to disabling the battery… every laptop I've used that had a removable battery did this by merely removing the battery. The laptop just ran off mains power. Does your laptop have a non-removable battery by any chance?

    In Power settings, there are advanced settings that control min and max CPU, battery setting may have higher max setting

      I also checked that too and they are both on the same settings, min max ect.

    Heh … sometimes manufacturers implement throttling schemes that allow the CPU/GPU to run faster when plugged in - you do mean it runs slower when plugged in right?

    Some laptops require the battery to be present to run at full speed. This is due to the power adapter not being able to supply enough power when under load, so the CPU is throttled lower to compensate.

      The only time that this can happen is if the OP is using a cheapie aftermarket charger.

      Manufacturers always include an adapter that outputs a wattage higher than the battery drain from the machine itself so that the it can be used while it's being charged.
