Hotkey driver keeps changing screen brightness.

I have the NP8275. When I have the Hotkey program installed, everytime it loads it will reset the display brightness. Usually it sets the display brightness to full, which is too bright for my enviroment. I have tried setting brightness manually, and in the power plans, and even the advanced power plans, but the Hotkey program over rides those settings.

Is there any way around this? Can I edit the values the Hotkey program is using to set the display brightness? Without the program all the fn key functions work except for the keyboard light controlls. Is there another way to controll the keyboard lights?

Thanks.

 

Seems there might be no way around this? Does every one else just use full brightness?

 

My new np9570 behaves similar. Every time I restart my computer it seems everything is reset. Screen brightness and touchpad are always on/full brightness I don't know why. I'm going to do a complete reinstall next week when I get my ssd and we'll see what happens. Getting it to my preferred settings is just a couple of keystrokes away but it is a minor annoyance that I have to do it on every reboot.

Is yours a new machine/windows install too?

 

I'm having the same problem. It also resets the screen brightness to 0% whenever I resume from suspension or lockdown.
Uninstalling the hotkey driver solves the problem, but then I miss the keyboard light controller...

 

I upgradded to a SSD, so I installed Windows 8.1, and loaded all the drivers. I think some place in the Hotkey software it has defaults for the different modes. So if you use Performance mode, it sets the screen to full bright, amd other modes have other settings. I wonder if we can find that file and edit it? Or if we could find the source program, we could edit the program directly.

BTW, without the hotkey program, I get no keyboard lights when resuming from sleep mode. And of course I can't turn them on or change them.

 

Do you guys have it set to performance mode in the hotkey/control center? I wasn't really paying any attention before I just set mine to performance initially but now looking at the options there is a setting for user defined just select that and it will remember your brightness settings. That solved the problem for me.

 

Yes, I had mine set to performance. So does user defined give you a settings page so you can specify everything thing? Just wondering how you know it is setting the cpu and gpu to "performance" settings?

Any way, thanks for the tip. I will have to install the Hotkey program again and try it.

 

No, not really. You just have to click on user defined in the hotkey settings and that's pretty much it! It will keep whatever brightness settings, volume, etc. you have there. Just set the "power conservation" option to performance and you should be set. The only thing it doesn't seem to remember is the touchpad it always defaults to on. I want it off because I use a gaming mouse so I have to turn it off everytime I reboot the machine but everything else sticks.

Also, go to windows power control settings and set it to high performance, and do your sleep settings, etc. there. Oh, and having the keyboard backlight is nice too. :thumbsup:

 

Just make sure to go back to balanced when on battery.

 

So you can get throttled to half the CPUs capability while on battery? This is what happens on my W550SU. This stupid hotkey driver thing is ruining everything. Perhaps as a reseller you may have some advice?

I've removed the hotkey and powerbiosserver service but after a reboot, I'm still being throttled on battery. Bear in mind this laptop has no dGPU so there is no need for such harsh throttling.

 

Can you post up a graph showing cpu load vs frequency.

High performance will stick the cpu at a higher frequency and waste power usually.

 

I'm not sure how I would go about doing that. I think the issue is related to changes in the registry that Hotkey makes, which it does not revert when uninstalling. I think it's the registries in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\PowerSettings\54533251-82be-4824-96c1-47b60b740d00 "

These are responsible for certain power management settings/schemes which are not normally available for the user to change.

Is there a way to perhaps reset these to windows defaults?

 

Windows performance monitor along with a monitoring program like core temp would work.
