battery performance horrible

Hey all,

Have had an MSI GE60 for probably 5 months now and just wanting to get some help with the battery settings. On AC power everything runs fine, but on battery every single game will only run on the integrated GPU.

I have done all power settings, have CPU at 100% and GPU on Max Performance, have set my global GPU settings (normally on auto-select) to only use the Nvidia GPU, however any game i run will NOT run on the 750M they only run on the integrated GPU. 90FPS in DOTA2/WoW on AC power, on battery i'm getting 15-20 FPS on integrated GPU. Try as i may, it will not run the 750M on battery.

Am i missing something? Is there some setting that needs to be changed? I don't care if i only get 45 mins-1 hour battery life, i need to be able to occasionally run my laptop off the battery.

Any help would be appreciated.

Regards,
Rish.

 

The batteries on notebooks are not able to provide enough power for dedicated gpu and cpus to both be on and operating at full power.

you would care if your battery melted.

 

AC adapter is 120W.
Battery is 50W.
So the performance is going to be weak if playing games off battery.

 

Wow ok then... I never had this issue with any of my Asus or Alienware notebooks though? This is really horrible if you're saying that by design the laptop simply can not run at full performance on battery.

At least on my G73 it will run at full power, i only get 30 minutes of gaming battery but that's still better than 6 hours at 1/2 power.

 

can't people just quit that pile of inverted tetrahedrons saying "my this and that can do this but yours can't"

its not a design flaw, its a design that suits the majority of the people, and no, i won't be gaming without a power socket just to get a sudden powercut in the middle of a game, and yes it is annoying, so does the way you lay a multicolered shirt out

why don't I do it the more annoying way:

At least my desktop with UPS will run at full power and product 5 times your G73's performance, I only get 3 minutes of gaming battery but that's still better than 30 minutes at 20% power (compared to a 5 times more powerful desktop, i did not do my math incorrectly)

 

G73 did not use Optimus technology therefore the graphics was fully managed by the nVidia GPU.
Pretty much all manufacturers implemented Optimus technology since Ivy Bridge era therefore Intel HD is primary graphics and Nvidia is slave unit linked to Intel HD graphics' circuit.

Also, G73 has a 150W AC adapter and a 75W battery. It's a 17" unit that is heavy/bulky/high performance compared to GE60's lighter/more compact/mid-level performance.

 

Read what Anandtech said about gaming on the Asus G73 using battery power.

lol it's like saying your smartphone runs at full power without the USB charger plugged in so why doesn't your near-desktop replacement laptop do the same?!

 

Lithium ion batteries are not designed to discharge so quickly.

 

Ahuh kay... None of your mocking comparisons are even slightly related to what I'm saying.

I have a G73, M11x R1, M11x R3, and GE60.

Every single one of my laptops can play DOTA2 on battery, except for the GE60. Even the M11x R1.

Considering the spectrum of their specs, the GE60 ranks in at 2nd most powerful. So perhaps SOMEONE can try and understand my confusion rather than simply mocking me for being an idiot. I have systems both more powerful and less powerful which do not struggle, while this one does. The 335M and 540M both use Optimus too AFAIK, yet i can force the dedicated GPU to turn on through the Nvidia settings. On the GE60, the 750M seems to simply not turn on while on battery regardless of what i do.

 

Let's get back to the original question please; the OP wants to know how to use the dedicated gpu on battery power, not debate quantum physics.

 

It's a firmware protection to protect the battery, there is nothing you can do to change it.

You can try and improve the performance of the iGPU with faster memory and tweak your settings since DOTA 2 should be able to be run on the intel.

People would have suggested things to help if there were things.

 

750M consumes about 35 to 40W, and the battery pack can only supply 50W.
That majority of power must be directed to the critical components but not the discrete GPU so you will only end up having Intel HD Graphics and nothing more.

Yes, things like the CPU, system memory, chipset, screen, battery, speakers, they all have to be allowed to run and not cause the battery to melt.

 

??? It's entry level.

dGPU will run with AC disconnected on my GE60 albeit at low clocks, but I personally wouldn't run it like that. Much prefer to use the battery as a backup in the event of an AC power cut.

 

Perhaps if instead of trying to maximise performance off-battery, you limited Max CPU power to around 60-70% on battery power? I'm not sure whether or not this would have any baring on the issue, as the refusal to run may be integrated into the firmware as previously suggested, but if not then you can tweak with your GPU settings a little I'm sure, and get less performance than AC, but still use your dGPU. That is ofcourse, if it does change the power required after all. Maybe even forcefully underclocking to reduce voltage?

 

That's actually a very good point, but what if the manufacturer has thought about this before and prioritized the power allocation to processor instead of the graphics core? If yes, then it's hardcoded and cannot be modified easily.
Example: 70/30%? 60/40%? 50/50% (CPU/GPU)?
