    Hi,

    I got a Y580 a couple of days ago, and I must say I can't be happier - this is a great machine for the money.

    One thing i'm wondering though is how to get the exact same performance when using the battery as when plugged in. I feel like i've tried everything in the system settings and power management, but when for example i play d3 on battery its sluggish, and as i plug the cord in during mid-game, it becomes smooth as silk.

    is there some way to get this same performanc? This is upsetting.

    You can't. Gaming laptops give you the ability to game on the go as long as you have access to an outlet. The battery isn't giving enough power to the Dedicated GPU and thus, it downclocks itself when on the battery. Maybe in the future, we'll be able to game on batteries, but for now, you can only really game when plugged in.

    Wow, I didn't realize that. So my guess is that when on battery it switches itself automatically to the intel chipset?

    Good to know, thank you.

    I just noticed this when playing diablo 3. Plugging it in I get an increase of 20 fps but I did not know that at all. But what you said is it true? And is their no way to fix it?

    There is a way to fix it.... Plug it in. Face it, the battery does not have enough juice to power the Nvidia chip fully.

    Gaming on battery - don't do it. Your chemical battery cannot deliver the required 100W+ at 19V and ~5A without killing itself. The internal resistance of the battery would cause massive voltage drops at such high current loading conditions, not to mention a huge amount of heat generated which essentially causes the battery to fry itself. No laptop lithium ion battery is designed for that, so the manufacturers down clock CPU / GPU while on battery. Yes, the GTX 660M is available on battery, but the max clock is very low. There is nothing to fix in terms of hardware and software. The only thing that might change is the lithium ion battery technology - for that, go talk to the chemists, not Lenovo / Intel / NVIDIA / NBR.

    vow. This should belong to a FAQ of any notebook user guide. I know many people try to play 3D game on battery.
