Why has Dell crippled the Windows control panel advanced power configuration options on the Venue 8 Pro ?

:emotion-12: 

Dell crippled the Windows control panel advanced power configuration options on the Venue 8 Pro.

Dell needs to provide a fix the restores full Windows advanced power plan configuration functionality.

I don't mind Dell adding a new Windows power plan as the default but they should not cripple the Windows power configuration panel, power options, or remove the standard Windows power plans.

That has something to do with connected standby settings / configuration Microsoft / Dell are doing on these units. Same is for the Venue 11 Pro MS versions. vPro units are different because no connected standby support. With connected standby on the available settings are limited to what would not interfere with it. If you would change settings (e.g. SSD or Wifi power management to disabled) issues come up like sleep function disappearing and others. Microsoft also has requirements to be Connected Standby certified.
Again, not 100% sure if it's MS or Dell doing it but my guess would be Microsoft because I have seen the same with different units.
If you disable connected standby all Windows power plans are displayed and all advanced power functions are available.

Use Regedit and change the below:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
Change the value of the key CsEnabled from 1 to 0 and reboot.
1 means connected standby enabled and 0 disabled.
Try it and see if it resolves your problem.

BTW: by disabling connected standby the battery display will also show the remaining time not just the percentage of battery life. :-)

Yes, it seems like hibernate + fast boot - not traditional OS sleep. The BIOS is definitely getting involved in a fast boot restart (Dell BIOS logo appears). So the "Sleep" option is misleading. The processor and/or power states needed for true OS sleep do not seem to be enabled or available. It's fortunate that fast boot is very quick - but it's not a true sleep allowing wakeup by traditional means.

iGetThis,

We're straying off topic, but at least there are a few "paranoid" security minded folks, like us, who have been around for awhile and see the dark sides of CS.  Also, there is a real false sense of security being spun about Bitlocker and TPM as well. It all sounds secure until the next backdoor is found, or the Bitlocker or TPM  keys are cracked, or bypassed by those who already have the "secret" keys. And all the secure platform stuff doesn't automatically protect your or your system, especially if its running and has access to the web. So many tablet devices don't even have a physical off switch for their wi-fi or cell modules. We know that any legit app can cross the line, become malware, or open backdoors to hijacking. Well it's all so transparent to security minded folks like us. I'd LOL too if it didn't bother me so much.

Bottom line - Legacy OS sleep full functionality needs to be restored when CS is disabled. And shutdown must truly turned off and powered down the device even with CS enabled.

Unfortunately, at least when I tried this, "normal" Sleep mode doesn't come back--but hibernate mode does.

That is the way it is. Either you let Windows manage everything (standby / sleep using connected standby) or user defined without it. So far I have not found a way around it for these kind of devices that are designed for connected standby.
As far as I know Windows does not have / use normal sleep mode, only Standby (Connected Standby) for devices that use / are designed for and support it.

I have some real security concerns about my tablet, phone, or desktop actually running in ultra low power mode when I think that it is shutdown. The TPM will allow anyone with the secret access key (Microsoft, CIA, NSA, others?) to take control of the system, track you, access your programs and files, etc. And Windows running in CS lets programs and apps do the same - a bonus for hijackers.   The fact that CS disables so many power, sleep, and other options make me really suspicious about the true motives of those supporting it. 

I'm a retired software developer/designer and I know that there are a lot of folks developing Win 8 apps and programs that run in the background and do all sorts of nasty things to collect data and violate privacy - CS gives them 24/7 access. :emotion-45:

Mikerman,

With CS disabled, sleep mode is still available under "Power buttons and lid" options.

I set my Venue 8 Pro to sleep when the power button is pressed and it seems to work. :Press the power button  again, for a couple of seconds, the Dell boot logo apprears and the system quickly wakes up.

Interesting--it didn't work that way for me. If I recall, the Sleep option was there initially but then disappeared once I delved into the action options (almost as if it was a vestige of the earlier settings). And when I used the power button to power down, the system hibernated (one could tell, as the front-side LED flashed), not slept. When I have the time and energy, will have to try it again and see what happens.

That is not connected standby. Connected standby by just press the power button ones the system comes back immediately (not holding it a few seconds). If the Dell logo appears it sounds more like hibernate and fast boot.

Yes, sleep is still showing in Power management for the button etc. but not really active. Took me some to figure out what was going on. Sometimes it's shown, mostly using a system where all the updates where installed (e.g. from win 8.0 to 8.1 update 1. That changed a lot by getting new systems from Dell that have or installing from USB / DVD Windows 8.1. update one from scratch.
To see if it's still available run the below command (Admin mode) and you see if standby is still active

Powercfg -availablesleepstates

vPro systems don't have that issue at all because they do not support connected standby (at least that's what I have seen).

[/quote] I think you're right. And when I had disabled CS, it in fact was a very fast start-up. AbsoluteJoe, do you get a flash of the front LED when you close down? If so, it's hibernate (as vs. sleep).

I have CS disabled on all our my tablets. First I considered it but after all the problems with battery drain and others? It just didn't made any sense to me.
Connected standby uses a lot more power compared to hibernate.
No need to update email, life tiles and other functions when I am not at the device. Is it really such a huge deal if you come back and get the system out of hibernate takes a few seconds more and e.g. in email click or touch send/receive? On a phone for sure but on a tablet that you could just shut down if not needed for a longer time? The boot up is what, 10 or 12 seconds?
Just don't see a real need for it.

Most important for me is that I just don't trust Microsoft or programmers writing code that does something in the background during connected standby what I have no idea about. Connected standby to me is a possibility to open a back door to access systems or Networks.

But hey that is just me and 17 years in IT Security Engineering (maybe got a little paranoid over time seeing what is actually going on). LOL

Hi,
My Latitude 5511 is really  noise event PC is not busy, CPU temp around 43C but fan rev higher. I thought closing the lid make PC hot, but then saw tread in question.  There is a  dell application to adjust fan Thermal Management, in my case Optimized mod but fan really noise, now switch to Cool mode and almost no fan noise when system idle, which doesn't make sense. Please play around with options to set up right configuration for your system.

I really hate what Microsoft did with new power plans and I hope in future there will be option to return to old power plans.

It worked, but after upgrading to windows 10 20h2
CsEnabled is gone, how can this be solved now?
