Power plans and CoreParking...

[polymono]

G'day, I'm trying to get my "High Performance" power profile to behave more like my "Power Saver" profile. In the standard Windows power plans area, I've tried to duplicate the settings from the latter plan, into the former plan, but it's made no difference.

This sounds like the reverse of what you think, but in several programs, particularly SketchUp 8, the "Power Saver" profile is so much faster, and more responsive, than the "High Performance". In fact, I'd say the "Power Saver" profile is perfect, but the "High Performance" is slow whilst using some programs in particular. For example, when using the select tool, and drawing out a lasso box in SketchUp, there is a terrible delay when using the "High Performance" power profile. But not at all using the "Power Saver" plan.

Since getting this behaviour, I've formatted and just found that it recurs, formatted again, with it still recurring.

I'm hoping someone here can offer some advice. It sounds like something caused by core parking, and I do have an i7 Asus laptop, running Windows 7. I stumbled onto BitSum when Googling for solutions for the issue.

I've run the stand-alone ParkControl64 program, thinking that core parking could have something to do with it, but the Enabling and Disabling parking seems not to have made a difference. That said, the visualisation / graphs of the % of parking seems very different in the two power profiles. In the "Power Saver" plan, the columns all "fill" at a roughly equal rate, and sit at a roughly equal level. But in the "High Performance" plan, the columns are vastly uneven, with one filling vastly more than the others, and the levels all very varied.

I found the same with power plans in the proprietary Asus "Power4Gear" software which came with my laptop, which just does exactly what the Windows power plans do, but with a fancy GUI. I've since uninstalled it, but could reinstall.

Any ideas at all? I'm desperately keen to resolve this. I'd be grateful for any suggestions or thoughts. Will the "Process Lasso" program be more suitable to diagnose this? I look forward to hearing from someone.

Thanks everyone, P

I don't have a direct answer as don't use that app but here is what I would do to nail down what is going on .

make a custom power profile in windows . you can copy either power saver one and start editing it to the high performance setting it uses .

That is only way I can think, add one by one the higher performance settings into your custom one to find which is problem and use that profile for that app .

Before you edit look and compare settings between power saver and high performance .

Of course if you just want power profile to switch to power saver you can do that with PL, just set it up in option app power profile .

G'day.

OK, so, I tried what you suggested. But it's not improved the situation.

Let me be clear about what I did: I made a new plan, which copied the "Power Saver" profile. Then, I changed the "High Performance" plan so as to exactly match the "Power Saver" plan. Exactly alike, in all categories. No differences whatsoever in the settings. They are duplicates in all ways I am able to change.

But there is still the same substantial performance difference between the two profiles / plans!

I even made sure to change the initially hidden settings... the ones hidden until you click the "Change the settings currently unavailable" button.

What should I take this to mean? The "High Performance" plan has exactly the same settings as the "Power Saver" plan, yet the laptop behaves very differently under them. Still using the "High Performance" plan, performance is bad, and not nearly as sharp and quick as the "Power Saver" plan.

Maybe I need to do the reverse? Like, copy in the other direction?

Or, maybe there's far more settings that control the behaviour of the plans, but which aren't shown in the options area.

One other thing worth saying, which will lead me to a question: Is there any way to lay out all the power plans / profiles on one screen, for easy comparison?

Two of the profiles I have work really well. The "Power Saver" and the "Quiet Office" are great. But two are really bad. The "Entertainment" and "High Performance" aren't nearly as good.

If I can lay them out on one screen easily, I might be able to see what the two good profiles have in common.

Unfortunately, seeing any commonalities between these profiles is nearly impossible in the Windows power plan options area. The tiny window in which you expand all the options only shows a small portion of the full range of settings in a single profile at a time.

Is there any way I can lay out the settings of these different plans, on the one screen, or one print, for easy comparison?

maybe that helps .

Another Asus user here.
if you has update to the newer version, which is clicking Fn+Space will open the "Power4Gear", not switching between the PowerPlans.
Then you might having a broken PowerPlans setting.
Try click on each power plans "Change plan settings", and click on "Restore default settings for this plan" to restore High Performance, Balanced and Power Saver back to the default setting.

If you are unlucky like me, you might also have a broken TouchPad software/driver, which having the same Power4Gear bug, always change the PowerPlans setting after you unplug the AC Adapter and start using battery....

And yes, I has been checked for hidden setting, each of the PowerPlans are having the difference hidden setting value.
Try using "LatencyMon", it can be the DPC Delays issues.

didn't know about Asus software but that is why I said add a new profile . I never like idea of editing the stock ones and for sure you never want to delete them .

funny thing on this win7 64bit I was looking around registry and seems there are other power plan keys that don't show up in power config of control panel

HKEY_CURRENT_USER\Control Panel\PowerCfg\PowerPolicies
seems there home/office , portable/laptop .presentation , high performance . 

not sure what they are , little OT .

I think you can't delete it, you can only restore to default setting.
And yes, switch the value on regedit will show up the settings in PowerPlans.

From what I've investigated, power schemes are stored in the following registry keys:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\Default
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power\User\PowerSchemes

[edkiefer]

yes, that looks like defaults used in OS .

yes, that looks like defaults used in OS .

The second one merges Default + User defined schemes.
