Dell Axim X51V Mirror Mode PDA screen off - General Topics

Dell Axim X50V / X51V have "Mirrror Mode" that enables VGA output at PDA connector.
When in Mirror Mode PDA behaves very slow because graphics chip Intel 2700g must drive 2 displays. Driving PDA display can be turned off by pressing POWER + RECORD buttons at a time, this way PDA returns to its normal speed because 2700g drives only external display.
How can I do it from soft-keys, batch file, shortcut, writing my own application or whatever else software way?
NOTE:
Stantdar method to turn off PDA screen does not work. It just turn off PDA LCD but 2700g is still driving 2 displays.

Finally I downloaded Intel 2700g SDK and I could write my own application.

New power consumption tests (incl. HTC Wizard and Universal)

New power consumption tests (Dell x51v, HP hx4700, PLoox720,HTC Universal and Wizard)
I’ve constantly been receiving requests (see for example this thread) to publish more and more power consumption measurements of current Pocket PC devices. Here you are
First, please read at least this article (if you haven’t already done so) to understand what this article is all about. I also highly recommend the other articles I’ve linked in from the Recommended links section.
HTC Wizard (a.k.a. imate K-Jam, T-Mobile MDA Vario, Qtek 9100, MDA Vario, XDA mini S, SPV M3000, VPA Compact II, Dopod 838) radio power consumption
As promised, I’ve run some long-lasting tests to find out more about the power consumption of the radio unit itself. It’s about 7.5% a day (I’ve measured it for two days; not counting in the ~2.5%/day battery life depletion needed to refresh the dynamic RAM memory) in inactive (no SIM is inserted but the radio is online and is ready to initiate emergency calls) mode. Again and again, these figures, along with the ~9% (there, not counting in the ~2%/day RAM refreshing-related depletion either) of Universal, are relative (show how the power consumption of these devices’ radio compares) and only show how they fare at a given geographical location. That is, they can ONLY be used to compare each device’s being power-hungry, NOT as an absolute result as “your device will consume that much power a day in YOUR home”.
Wizard’s 7.5% a day is an excellent result and is slightly better than the ~9% of Universal, particularly taken into account the bigger battery size of the latter.
Standard power consumption test suite: now, for the Universal and the hx4700!
I’ve also re-run my standard test suite including the HTC Universal (a.k.a. i-mate JasJar, Qtek 9000, O2 XDA Exec, SPV M5000, MDA IV/Pro) and the HP iPAQ hx4700 (with WM5 version 2.01 – see FAQ here on this particular ROM version) now to find out how they behave.
The test suite I’ve tested:
Backlight tests: (all with no wireless units (GSM radio, Bluetooth, Wi-Fi, IrDA) switched on, no CPU usage. This finds out the absolute minimum power your device at least will consume when it’s switched on, runs at the default (automatic) CPU speed.)
No backlight at all (Note that in this scenario these devices are far from being usable, particularly the Axim x51v, which has an, in my opinion, slightly less visible screen in external light than the other three devices (which all have a screen using the same Sony technology and, therefore, behaving in a very similar fashion)
(Absolutely) minimal backlight
Maximal backlight (may be useful to know for example when watching videos on Sony screens because of the very high contrast and saturation of these screens (the x51v's not-really-saturated, not-contrasty screen has a definite advantage here) or in outdoor circumstances when you need to use the maximal backlight level available to see anything)
Wi-Fi searching for networks (also testing possible power saving modes to find out whether they’re of any help)
CPU usage vs. power consumption tests with Resco Audio Recorder (recording in q:3 32 kHz 19 kbps Speex mode (my favourite one with the best size/quality ratio but, unfortunately, with pretty high, about 60% CPU usage) - please see Everything you may need to know about sound recording on the Pocket PC for more information.)
Note that, this time, I’m also stating the original charge level at the start of the test. As is also stated for example in this pretty nice article by Brighthand forum member tanbam, there may be slight (not much) differences in power usage depending on the charge level of the battery because of the proportional Voltage level decrease as the battery is discharged. (Note that the Voltage decrease with Li-Ion batteries is in no way as visible as with other kinds of batteries. That is, a Li-Ion battery that only holds little charge will still have only a bit less Voltage than a battery full of charge. This is why there aren’t major differences in the low-charge and the fully-charged cases, Amperage-wise).
As can clearly be seen, what I’ve stated in my first battery consumption-related articles and tests is still topical:
when there is some remarkable CPU usage (see the Resco test), the power consumption figures skyrocket, particularly with the iPAQ and the x51v, particularly because both are 624 MHz devices, as opposed to the 520 MHz Universal and the PL720 (the latter consume decidedly less power in these cases). It’s, therefore, essential that you use some kind of CPU underclocking, especially on 624 MHz devices, when you run an application that constantly uses the CPU.
Fortunately, CPU underclocking is already supported by the x51v (in the Processor tab in the Settings/System/Power applet) but, unfortunately, not in the hx4700. Note that the Resco results are almost the same in the 624 and the 520 MHz modes; it’s only in a heavily (on the verge of usability underclocked) 208 MHz case that it’s visible decreasing. The case is a bit different with games – please see my former articles on the power consumption of the x51v and on my remark on what applications / games run OK when you (radically) underclock the device.
the Pocket Loox 720 is by far the best device, power consumption-wise
the lowest backlight level (with the – this is very important! – automatic backlight mode enabled as can be seen in here – it’s not enabled by default!) with the hx4700 consumes very little, as opposed to the other devices
when idling (without backlight – again, the hx4700’s backlight is far more battery-friendly than that of the other devices when used sparingly), the PL720 consumes the less; then comes the Universal, the x51v and, finally, the worst-behaving hx4700.
the various Wi-Fi power saving modes aren’t worth anything (at least when the device is actively searching for networks). In Wi-Fi, it’s again the PL720 that turns out the most power-saving (in my personal tests, it consumes about 25% an hour with BT enabled – connected to a StowAway BT keyboard -, in Web browsing mode, with the lowest backlight and connected to a Wi-Fi network).
BT and IrDA: Note that the chart doesn’t contain Bluetooth and IrDA beam activation power consumption data because I’ve already published them all. In a nutshell: you can freely activate and, with Bluetooth, actively use them (it’ll only result in an additional 1-2 mA power consumption, except on the PL720 in BT PAN mode, where you have taken into account what I’ve stated here), except for the hx4700, where it adds another 80-90 mA power consumption.)
finally, the Universal has turned out to be pretty good surprise: I’ve expected far worse, based on real-life usage. (Read: I need to recharge it on a daily basis with even moderate Web browsing – no hard-core gaming or stuff at all! – and mail reading while, using it in entirely the same way, the HTC Wizard doesn’t need recharging for days. Compared to the Wizard, it really sucks battery life-wise; compared to other VGA devices, it fares pretty well.) It fares decidedly better than the x51v and the hx4700 in almost every respect, particularly in the CPU usage and the Wi-Fi tests.

How to keep bluetooth connectivity in standby mode with a Dell X51v ?

I have a Dell X51v and a HTC universal, both of them have been upgraded to wm6. When I use the universal(I removed the sim card and disabled the phone function), I connect it to a Nokia mobilephone E61 through bluetooth and let the E61 as a bluetooth modem. And when the universal turn into standby mode after several minutes I don't use it, the connection is still keep alive. But when I use the X51v instead of the universal by the same method, there is a problem,that is when the X51v turn into standby mode,the bluetooth of X51v automatically turned off,and it disconnect with Nokia E61,and the internet connect is lost.
It's really drive me mad. As I want to use X51v to get windows live messenger online all the day.But the problem makes it impossible.But why the universal is OK?Can the X51v perform just as universal?Just not to disable the bluetooth funtion when in standby mode?
wait for a method,Thank you.

welcome to xda-devs
this is a fundamental difference between the "standard" Pocket PC OS and the Phone Edition one and can't be fixed. all you can do is disabling the auto-shutdown on the x51v and just use screen dimming and/or button locking

Oh, it really seems bad to me.keep live messenger online is very important for me, but the battery can't be used long if disabling the auto-shutdown

Dual Monitor w/ MST Hub Problems (SP3)

I came into the SP3 world after many hours researching to make sure that dual external monitors was a possibility, specifically without using USB-powered "external video cards". However, after following directions that people have posted before I have the below setup, and only one external monitor is being displayed.
System: Surface Pro 3 i7 / 8GB / 512GB SSD
Microsoft Surface Docking Station
2x HP LA2206x Monitors
StarTech Triple Head DisplayPort 1.2 Multi Monitor MST Hub
StarTech Mini-DP to DP Adapter cable
Plugged in like so:
Docking Station -> Mini-DP to DP Cable -> MST Hub -> Output 1=Monitor #1, Output 2=Monitor #2
The Surface continues displaying on its screen, and Monitor #1 gets output. Monitor #2 seems like it tries to initialize (I hear the "da-dump" sound from the Surface when it gets plugged in/unplugged) but no video output.
I have tested the MST Hub on another laptop (HP Elitebook Folio 9470m) and both external monitors display without issue. The only difference between the two setups is the Mini-DP to DP adapter cable is not required/cant be used for the setup on the 9470m, as it has a full DP port on it.
Any help would be appreciated, thanks!
Have you looked in the "Screen Resolution" control panel (right-click on the Desktop) to see if the second external monitor is shown?
Have you tried using Win+P to disable the internal display?
Have you checked Device Manager to see if both external monitors are detected correctly and have working drivers?
Have you verified that MiniDP can drive multiple displays at all?
Have you verified that MiniDP can drive the total display resolution that you're trying to run off of it?
Have you verified that the SP3's video chip can drive the total display res that you're trying to get (remember that the internal display is very high resolution)?
Those are the things I'd check first, in probably not quite that order.

1) Second external does not appear in Screen Resolution
2) Yes, however SP3 devices support 2 external plus internal as per spec sheet
3) I will check this.
4) As per SP3 and DisplayPort 1.2 spec sheet, yes
5) As per SP3 and DisplayPort 1.2 spec sheet, yes
6) It is listed on official documents as an advertised feature for 2 external as well as the internal
For #6 I was specifically asking whether it could drive that much resolution, rather than whether two externals was possible at all (you might try reducing the res on the external panel and seeing if the second wakes up). You should also make sure that your hardware all works; try things like disconnecting the first monitor and making sure the second works when plugged in (leave it in the same spot on the hub?)
Beyond that... do you have a Microsoft store nearby? Even if not, you can try calling their support people. If nothing else indicates the source of the problem, it's probably the sort of thing you should take to the people who are paid to deal with such issues.
Working an issue similar to this now. Trying to use a two Dell U2414H monitors with DisplayPort 1.2 chaining, and a DP Hub. Both end in the same result as you.
Sometimes I'm able to "trick it" and get it working but after a reboot or shutdown the 2nd monitor goes back to disabled and I have to repeat the process. Right now I have it working using one monitor on the mini-DP, and the other on a USB-3 to DP adapter.
Working Microsoft on this issue. They claim there is a KB out for a problem with the dock (2992365) but I haven't been able to pull anything up using that number online.
I didn't have any luck with a MST hub either. I ended up just getting a USB video card adapter and I'm now using my SP3 as my primary work machine with two monitors.
Try it without the dock plugging directly into the dp port on the surface
Can you give me detailed explanation?

[Q] Auto Power On Linx 7 Windows 8.1 w/Bing tablet

Hi guys,
Couldn't find a forum for this tablet (Or it's twins, the Connect 7 or Pipo 7). Details below. Hopefully it's in the right place, if not could you let me know/move it?
It's a Windows 8.1 based tablet, with UEFI firmware, with the BayTrail processor/architecture.
I'm attempting to find a way to auto-boot it when power is applied - at present it will wake from connected standby when you apply/disconnect power, but it will not power on from being shutdown / hibernated (even when battery drain caused the hibernation).
There is an option in the BIOS about power state when external power lost, however reports have said this will brick the device completely which i'd rather not do!
Anyone got any ideas?
Cheers

Prixton PC02 Tablet, Windows 10, Black Screen

Hello everyone
I have a Prixton PC02 Windows 10 tablet (and bluetooth keyboard), Windows 10 asked me to update it and I said no then the tablet went crazy, now when I boot the tablet up it shows the Prixton logo then the screen stays black (but with brightness so I can still see it is on). With the screen black if I press the touchscreen I can slightly see the cursor and a blue loading circle.
I have tried a few solutions to get Windows 10 to load normally which are:
1- Drain the battery completely with it on the black screen and then charge and restart
2- Use the Windows 10 USB recovery.
Now, with the USB plugged into an adapter into the tablets micro USB slot, the tablet loaded from the USB drive, once in the recovery menu I tried to diagnose and fix problems with the boot of Windows, it shown as attempting repairs and then after a while it gave me a message saying that it cannot be repaired.
Another option I tried was resetting the device, this starts to work up to 2% then it boots me back to the recovery menu.
Now the tablet won't load the USB at all
Just wondering if anyone knows of any other possible solutions? And thanks if you do
Later I will buy a MicroSD card to see if I can boot from that.
Tablet details:
Touchscreen: 7" 1024x600 TN
Operating System: WINDOWS 10
CPU: Intel® AtomTM Z3735G (Quad Core, up to 1.83GHz)
Internal memory: 16GB RAM 1GB DDR3L
