I see you have GTX675M_P1_080v_085v_092v.rar , have you had a chance to look at the GTX675MX version?

Thanks

Question: Does the Prema bios invalidate the warranty? Would there be an issue if I return the laptop for a warranty repair? Thanks

I am not sure what you want?!?

Crossflash P170EM version to your P15xEM.

Thanks that worked! Much appreciated.

Is there a way to get the Intel XTU software so it's not grayed out? I'm unable to change anything. Thanks

Thanks for modding the vbios! I'm now able to play off battery and have good performance on my train ride in from work!

You can backup your old BIOS & EC with Afuwin (attached). Also no problem in using the mod.

OK backup my current BIOS and flashed with your BIOS but I didn't see any additional options in the BIOS. Could it be that I have a newer BIOS and it's locked down more?

I was going to update to your bios and slv7's kepler bios and was wondering should I do the laptop bios or video bios first?

Also, I currently have BIOS: 1.02.17LS1 & EC: 1.02.11SA. Will I have a problem updating to your bios and how can I backup my current BIOS before I update? Thanks

The 680m with default BIOS will not run on battery. The 675m is likely the same. svl7's BIOS allows the 680m to run while on battery, however, the system will shutdown in seconds if at normal 3d clocks and voltage. A workaround is to use Nvidia Inspector to force the GPU to 2D voltage and clocks, then you can overclock the 2D clocks. 2D clocks are capped at 405MHz core, 1600MHz effective (400 actual) memory, which is far below of what 2D voltage should be capable of.

You also may have noticed that the CPU is limited to a mere 1500MHz when on battery. You can use throttlestop to get rid of this cap.

With the above fixes I get slightly over an hour on battery while maintaining performance levels expected of a gaming laptop. The IGP will draw up to 20W when fully loaded, so battery life is hardly any better when using it instead.

Thanks for the tips. I'm really thinking about applying Clevo 675mx (4GB) - 80.04.58.00.05_'OCedition'_rev00 from svl7 and Prema's bios.

Nope, but you can use Throttlestop and disable 'EIST' to run the iGPU on full during battery operation.

If you want to use dGPU on higher speed (which will simply eat up battery), you can use Nvidia Inspector and OC 2D clocks.

Tried to use Nvidia Inspector but it keeps crashing with unhandled exception error on Windows 8.

Still I would expect it would be faster than a GT230M on battery. Anyway to improve the performance?

Does P150EM_16_11PMv1.0.zip unlock the GPU clocks in the bios for when on battery?

Do you have more control of the laptop's performance on battery?

How can I get faster performance on battery? I got a Clevo/Sager P150EM with a Geforce GTX675MX. It really doesn't seem much faster than my other laptop with GT230M when on battery. I turned on preferred adapter to the nvidia, and max performance in the Nvidia control panel also set the power settings to high performance. It looks like the card is pinned at 135 Mhz cpu 400 Mhz mem on battery while the GT230M ramps up from 135 Mhz to 560 Mhz.cpu 790 mem on battery. It seems like it might be dropping back to the Intel HD Graphics 4000 card. Thanks
