I am trying to setup an EP10 to turn off the screen/handheld after one minute and that works fine. However I need our technicians to be able tap on the screen to turn the unit on again as they have to ware large gloves and they cannot press the small red on button with them. In the EP10 manual it states that when the the .Turn off screen if device not used for..' option is selected, the screen should turn off after x minutes of idleness and that the user can turn on the sreen again by just tapping on the screen. However, it does not turn on by tapping the screen! If anyone has previous experience and an answer for this then it would be gratefully appreciated!
Regards,
Liam
Sean/Alex,
I checked out these tweakit changes and it worked perfect. I think the tweakit interface is fine for changing these settings. So, while an improved interface for the power settings would be welcome, I think for me personally and probably similarly technically minded, a detailed list of registry/tweakit settings that may be changed depending on how we need the unit to perform in the field for different projects would be useful so that we can optimize the performance of the unit!
Hi Liam.
Can you give me the "exact" steps you use for setting the following two settings:
1) Start -> Settings -> Power Control panel applet [Advanced] tab.
2) Start -> Settings -> System -> Backlight Control panel applet [Battery] and [External Power] tabs.
I just wish to test this on a PH8 (GSM/GPRS) model I have here at the Help Desk. -sean

Sean,
1) I simply go the advanced tab and set the 'Trurn off screen if device not used for' setting to 1 minute. Then I make sure that this setting under 'On battery power:' is on, i.e. there is an 'X' in the chck box under this setting. I then make sure that the 'On external power:' setting is off, ie. when it is charging the unit is not turned off automatically but you have to turn it off via the on/off button on the keypad.
2) For the backlight I simpley set the Battery setting to turn off the backlight after 1 minute and set the External power to turn off after 10 minutes and both battery and external power hav ethe tap screen to turn on the hh set to on!

Thanks for that Liam.
In fact I encounter the same issue as you do. (Not an error on you part) I checked the EP10 Manual, and it contains the line:
*** Begin Cut ‘N Paste ***
Note: The options in the screen behave like Suspend mode. If the screen turns off, the unit is in suspend
mode – tapping on the touchscreen or pressing a key opens the screen in which you were working
before it was ‘turned off‘.
*** End Cut ‘N Paste ***
Which I would reckon is part of the expectation that you have for being able to resume by a Keyboard press, or a Screen Tap.
That aside --(I have Notified our Product Support Group of this inconsistency)-- the behavior of setting the Power Option in Part 1) of your response (Thank You) will not shut off the screen of the device -- but will Suspend the device.
The only button that will return you from Suspend is the [POWER] button on the EP10 Keyboard.
I have tested your scenario on a device I recently .CLEAN booted and brought back to correct config (*), so there is not possibility of 3rd-party applications causing interference of any kind. -sean
(*) After a .CLEAN, an EP10 which does not have a Total Recall backup/restore profile will need the Correspondent ADD-ON.CAB file installed, and if the EA11 imager is intalled, the Decoder Installer for the EA11 driver installed as well. -smk8
Thanks for the reponse. I will continue to test myself to see if I can find the solution.
On another note, I did not realsie that there was .clean boot option. How can this be carried out and is there any files that I need for it?

It could be that there's no way to set the "wake on touch" option. Look for the following registery key: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power]. The value is a bit mask, to enable wake on touch, OR with the value 0x10. You may need to reset after making this registry change.
Looks like I missed the actual registry key name: WakeupEnables
And be very careful making changes to the registry - I'm only telling you this so you can test out the functionality, it's not intended to be a field solution - if it works as expected, then we may need to add support in the OS for the option to be selected.
Thanks Alex. I will try that from my end. -sean
Hi,
Does anyone know why we state "Turn off screen" instead of "Suspend the device" at Power Applet?
The first option may lead audience think that devices go to 'Screen Off' power status instead to Suspended one. http://msdn.microsoft.com/en-us/library/aa929251.aspx
IMHO, if EP10 were consumer devices 'Turn off' may be the best choice since it is easier to understand what it means for non-technical users. But being EP10 enterprise devices we should be more precise to communicate to IT staff what we exactly mean.
I tried changing the WakeupEnables registry value but it does not seem to work. Below is a screen shot of the Power registry key settings. Can you suggest any changes that can be tested?
Secondly is there a list of power registry settings with a corresponding explanation of what they should do when set to a certain value avalable?
Answers in Two parts.
1) Felipe, it was the phraseology in both the EP10 manual as well as the Phrasing in the Power Control Panel applet that I brought to the attention of the Product Support Group.
2) Liam, I am expecting you to encounter that the registry settings will not WakeEnable the EP10 from Suspend (I confirmed that it did not work this morning) but was still composing this message to let you know. As well to let you know we are looking into that.

Liam.
I was making a mistake when trying the tap to Resume. It is closer to a Tap-Hold. And the best way is to use your thumb. When the EP10 is suspended, you can [THUMB-SCREEN] to bring the unit back. This is due to the tap-debounce parameter to prevent the EP10 from being resumed when something just taps the screen lightly.
For WEH running across a varienty of platforms (Including the EP10) the registry value changes from device to device. This registry implementation is specific to the EP10 running Windows Embedded Handheld firmware. We will investigate a User Friendly control panel setting for all devices running WEH.
Please try the setting using 0x10 (ten hex) OR'ed with the existing value for WakeEnable and then when you suspend using either [POWER] button, as well as [BLUE] then [POWER] and using your thumb press gently (but firmly) on the screen for ~ 1 full second and the unit should resume. It did on mine that I reckoned was not working correctly. -sean
Nice find Alex. Thanks a lot
I also tried this and it works!
Ex. EP10 OS 2.0.18516.0 configured with [X] Turn off screen if device not used for 1 minute
Per your instruction:
168 (Dec) = 10101000 (Bin)
10 (Hex) = 00010000 (Bin)
---------- Boolean OR -----------
10111000 (Bin) = 184 (Dec) = B8 (Hex)
Before:
After:
=== Warm reset required after making this registry change ===
To resume, TAP and hold until the center LED (Yellow Application LED) comes on

That is excellant feedback. Unfortunately I am out of the office until Monday at least but as soon as I get back I will check this out. Looks good though!
