Y500 powersaving/gaming

2013-04-15, 15:25 PM

Hello dear Lenovo lovers :D

 

I have a few questions about power saving on a lenovo Y500. I know that Y500 isnt designet as a long-battery-life-super-power-saving machine, BUT maybe i can do something to make it last longer on battery. I was thinking:

 

1. Is there any way that i can enable the (by Lenovo disabled) onboard intel graphics? So that windows doesnt run on the 650m?

2. IF NOT, can i completely disable (turn off) the second GT 650m? So far i know, it only turns to idle when not used, and still uses power and generates heat. And please dont tell me to take it out physically. Thats not an option in my little perfect world :)

3. About heat: I was playing portal 2 and measured the CPU/GPU max temp. Can someone please tell me if i have something to be worried about. I know that laptops generates more heat than desktops:

 

Max temperatures (Celsius):

CPU Package: 87

CPU1: 87

CPU2: 86

CPU3: 87

CPU4: 86

GPU1: 73

GPU2: 39

 

I was playing on one GPU (SLI disabled)

 

Machine Specs:

Lenovo Ideapad Y500 SLI

  • Intel Core i7-3630QM 2.4 GHz
  • NVIDIA GeForce GT 650 (SLI) / 2 x 2 GB
  • 8 GB RAM
  • 1 TB HDD
  • 256 GB SSD
  • Full HD display
  • Windows 8

The Intel HD4000 is disabled via hardware, not software. It is 100% *not* possible to unlock it.

The second GT650m is disabled and doesn't run on battery automatically, not enough power.

There's not really anything to be done, sorry.

 

 

EDIT: For temperature information, see here and the discussion on overvolting.

It's the GPU and CPU sharing the same heat pipe and running under stress at same time. Seems to be normal for this machine.
