Tm2 touchpad is completely unusuable even when working perfectly due to drivers
It seems there is a flaw in the touchpad drivers. If you use two hands on the touch pad, one to move the mouse and another to click the buttons, it becomes unusable.
This touchpad has physical click buttons that double as part of the touch area. If you leave one finger physically resting on a button, it messes with another finger trying to move the mouse. Worse yet, even if you change the way you use it so you use one finger to move the mouse and touch the buttons only when lifting this finger, it becomes impossible to highlight text.
Since in order to highlight text, you have to keep the physical button pushed in while trying to move the mouse. The pad basically sees this as a tap or something and breaks the dragging so the highlight area stops growing as you move the mouse.
It would seem the drivers need to have a setting to either virtually shrink the area of the pad that is used for mouse movements so any area outside of this area is not used. Or needs to be self aware of physical buttons and have a toggle to not activate the touch area above the buttons.
I have tried to see if I could maybe set a scroll area or any other area over the area of the buttons to help alleiviate this problem, but none of these attempted tricks have worked. Using one finger to move and another to touch the physical buttons just breaks everything and makes the pad unusuable.
What makes it worse is that the user made linux touchpad drivers for synaptic touchpads does let you define the phyiscal touch area. So in linux you could easily shrink the area so the touch area does not include the buttons.
There is no technical reason why the windows driver cannot support this. Just add a tab to the menu for touch area and let people define it with a box just like the current driver allows you to set touch zones. Then the feature is universal and it would work for any future variation of physical buttons and touchpad area.
I personally am in awe of how they could make a touch pad where the physical buttons double as touch area and not notice that you need a way to exclude the buttons from the touch area if you actually want to use them. Why did they make physical buttons that you cannot use? Do they not test this stuff?

Why is my battery discharge completely overnight even when the device is not in use?

EliteBook 2530p touchpad sending random commands - even when disabled
On my brand new 2530p running 64-bit windows 7 the touchpad is causing issues. If I touch it, then the cursor flies all over the screen and random commands are sent. For example, Visual Studio seems to be recognizing an F5 being sent it there as it tries to debug my current project.
On the laptop itself there's a little button that I can touch to disable the touchpad. That light goes orange and a little window appears temporarily saying the touchpad status is now off. Touching the pad at this point still does the exact same thing....so even shutting it off isn't making a difference.Hi - Not sure if you have been told as yet, but the driver supplied by HP is currently incorrect. We have been rolling out Windows 7 onto these machines, and have discovered the same issue.
You will need to uninstall the existing synaptics driver from control panel > uninstall a Program, and then install the new driver on www.synaptics.com
This appears to fix not only the issue with the skittish touchpad, but also the issue with the touchpad not disabling when pressing the disable button on the touchbar.
Hope this helps! -
Executable not running properly even when running perfectly in development environment
Hello there
My application runs fine when running in development environment but as soon as I create build specification and run it, it takes time before reading signals and doesn't shut properly. I wonder if there is some settings I need to do in vi properties or in build specification?
Would appreciate comments
Kind Regards
AustinHi Austin,
I'm Oli from NIUK. I have a few questions that would help me to work out what the cause of the problem might be.
What type of build specification are you creating?
Did you receive any errors or warnings when building?
Are you running the built file on the development machine or another?
Would it be possible to send your project and files to me so that I can try to build it. It could be an issue with your specific PC.
Kind Regards,

IPod continuously flashes "Do not Disconnect" even when set to automatic.
iPod continuously flashes "Do not Disconnect" even though iTunes says "Update is Complete" and even when set to automatic update. It mounts both in iTunes and on the Desktop.
Any suggestions on how to fix this?
I have alredy tried rebooting both the iPod and computer.
Thanks.Patrick,
Welcome to the discussions.
Sounds like you've got Disk Use enabled. Try unchecking the Box "Enable Disk Use" under iTunes>Preferences>iPod Tab.

It is recognized via Itunes as IPOD and i am able to connect it through USB cable to the pc and manage its physical memory via My Computer. But the problem is I cannot use anything on it as an IPOD (Like Music video and note stuff inside it).It boots as saying its got low battery power and after a while "Do not disconnect" logo appears after it is charged, i am able to operate it as normal ipod but when i click something it gets hanged like a PC and it stays there until the battery is too low . No matter what button i press (Menu or play buttons) continuously or the combination to restart or reset its in the same static state,,no reaction...even when i connect it to the pc via USB or charger nothing happens ..it stays in the same screen whereever i navigated last. After all its power is used up the same process continues that i can use it as an external hard disk namely its 20 GB memory...
Is there any way I can solve this problem via Itunes restore or any other used method to restore it to factory settings ?? ...I haven't used any method to restore it until now as i have migrated to IPAD,,,since then i've been using this as an external hard disk....may be if its restored to old condition i can carry this where ever i want unlike the massive IPAD...its like carrying a solar panel unlike an handy IPODHi mafiose15,
Thanks for visiting Apple Support Communities.
Restoring your iPod to factory settings is the best way to try and get it back to working order. You can use the instructions below to restore it:
How to restore iPod
Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
Download and install the latest version of iTunes if necessary.
Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
Click Restore.
If you are using a Mac, you will be asked to enter an administrator’s name and password.
A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
Leave iPod connected to computer to complete restore (typically applies newer iPod models).
During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage.
Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time.
You can find the instructions in this article:

Workflow in process status when work is completed and returned to inbox
Issue...
Once upgraded to ECC 5.0, our Workflows are still in process status after completing the work item and returning to inbox. Takes several seconds to go to completed status.
More detail...
In a number of our work items in custom workflows we utilize methods that display a custom transaction for review & approval in the workflow process. From within the custom transaction we issue the terminating event for the work item by means of Function Module "SAP_WAPI_CREATE_EVENT" once the user approves or disapproves the work item.
This worked all very well in Rel. 4.6c. By the time the users were routed back to their inbox the work item had disappeared.
We recently upgraded to ECC 5.0 and experience the following problem. Once the user has left the work item and are back in their inbox, the work item is still on display. It eventually goes away once the users refresh their screen after a few seconds. This is very confusing to the users and some of them even wanting to start executing the same item again....
I was wondering if anybody has any ideas on how the completion/termination of the work item could be changed so that it completes faster and is gone from the inbox immediately.
In our research we did come across OSS note 831443, which explains as of release 6.20 that work items will be locked while executing a method and that the terminating event can only be delivered once it is unlocked. Taking this into consideration, we tried moving the terminating event to the end of the method within the business object program, but the work item never completed, even after refreshing the inbox.
Thank you for any feedback.Hello Tom,
I've had quite a similar problem with the terminating event in a dialog while the workitem is locked.
I came across the same SAPNote 831443, but it doesn't seem to tell the whole story there. As I found out, the status change (from "in work" to "complete") is just skipped over, while the workflow continues with processing, leaving a last workitem "in work" hanging out to dry when the whole process has already finished.
Basically the problem is, or was, that a popup dialog was shown to the user after the processed the transaction, which held the lock open. I have found no logs, saying that there was a problem with a locked workitem, anyhow.
At last I have found out, that basically there shouldn't be much coding between the <b>COMMIT WORK</b> statement and the coding that just ends the method with <b>END METHOD</b>. This kind of procedure does definitly apply to the newer Versions, as I didn't have any problems like this before. Mayhaps and only a guess is, that the unlock-operation was previously registered with a perform like PERFORM unlock_workitem ON COMMIT. or something similar. This defenitly has changed under the new releases.
In your specific case I would recommend to register the event processing in the update task and end the workitem's method as soon, as possible. For example:
CALL FUNCTION 'SWE_EVENT_CREATE' IN UPDATE TASK ...
If this still does not help, you could further disjoin the transaction processing from the event creation by adding
STARTING NEW TASK
IN BACKGROUND MODE
or whatever the correct syntax was here. This will schedule another tRFC on the database commit, which then is defenitly be picked up by another work process of the application server, just right -- hopefully -- after the object's method has completed.
If you're feeling good with this answers, or it least it gave you new ideas to look upon, please assign points as appropriate.
Best wishes,
Florin -
Is the W520 supposed to whirrr and click even when completely shut down?
I just received my W520 (#4270CTO) about 3 weeks ago. This is my first laptop (to be used for video editing and animation), so I'm not sure what to expect.
I noticed that when I shut down the W520 (go to "Start" select "shutdown"), it continues to make a very faint whirrr and click noise. The noise pattern goes like this: long whirrrr, click, short period of silence, then it repeats. It does this all the time when the computer is turned off. Even when I don't use the computer for 2 days, and it is turned off, it continues to whirr and click. It only stops when I disconnect the battery and reinstall it. Only then, is it completely silent.
Is it supposed to do that (the whirr and click all the time)?
The whirr and click noise is very soft, so you have to lift it up and listen to it but it is audible. My friend says that it is the hard drive noise, and said it should not be doing that, but he doesn't have a W520, and isn't familiar with it. So I thought I should ask someone else who has one to see if theirs is doing the same thing.
I also noticed that the fingerprint reader LED stays lit all the time except for when the computer is on and I'm using it. It stays green even when the computer is shut down and the lid is closed.
Please help. Is my W520 working properly, or should I call for tech support?
Thanks for any comments and advice.The power brick makes no noise. I am charging the battery now, and the power brick is warm but silent.
I've only noticed the noise coming from the underside of the computer when my W520 is turned off with the battery still attached.
If I remove the battery and reinstall it, the noise stops.
If I plug in the power brick, the noise stops. (The brick doesn't even have to be plugged into a wall socket. I could just plug the power brick into the computer without plugging in the other end to a power supply.)
Of course, if I remove the battery the noise also stops.
But if I use the W520, then shut it down and leave the battery attached, it will continue to make the faint long whirrr and click noise. I have let it sit without turning on the machine for 3 days, and it continued to make the soft noise every day.
I don't suppose your computer makes the same noise. Maybe my computer really is defective. It works great otherwise. -
This isn't achely a question it's about iPod not iPhone but can Apple. Make all apps work with iOS 7 even when it's really old
And it's totally impractical for any OS to provide complete backwards compatibility in perpetuity. So no, Apple cannot grant your request. As WJ said, it's the developers' reponsibility to provide updates to their applications to be compatible with newer operating system releases, whatever the platform might be.

Firefox crashed this morning on startup. retried, but keeps crashing. Sent multiple submits using the FF crash tool. Tried rebooting, but same result. Tried reinstalling FF7, but when asked to reboot to finish installation, the installation never finishes. Now even when I try to uninstall FF, I get a message stating that I need to reboot to finish the installation. I am completely hosed with FF right now... cannot run app, cannot reinstall, cannot uninstall.
Hello zalloy, try to delete the [http://kb.mozillazine.org/Profiles.ini_file profiles.ini] file in [http://kb.mozillazine.org/Profile_folder Profile folder], to see if the problem is there, restart firefox and check if working.
otherwise go for a clean reinstall and delete the Firefox program folder before reinstalling the new copy of Firefox, see: certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.
Please report back to see if this helped you!
if you can not delete the Mozilla Firefox program folder, try to boot Windows in Safe mode (press F8 on the boot screen) to see if that allows to delete that folder.
thank you -

IPad 4 switches off when i am using it, even when battery is fully charged. Restore function (holding down both buttons) often does not work. Cannot power up iPad. I have updated software, restarted computer, but no success. I did restore the iPad about 8 times during the past 2 weeks. Just completed another restore. iTunes says the the iPad has been restored and will restart automatically and appear in iTunes when it is ready. That was 30 minutes ago. iPad still won't start. I am looking down the barrel of yet another fruitless restore. What a crap product.
Try a reset:
Hold the Sleep and Home button down until you see the Apple logo. -
my iphone just turn it off for on reason, when i turn it on after 2or3 min it just shutdown by it self, and even when i charge my ipjone it works, but once i take off the charge then it shut down by it self again
Hello there, queen168.
The following Knowledge Base article provides some good steps for troubleshooting your particular issue:
iPhone: Hardware troubleshooting
http://support.apple.com/kb/ts2802
Particularly:
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIsand corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:
The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.
If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for reaching out to Apple Support Communities.

my speaker doesn't work when I try to listen to music or open up a quick time file, however they seem to work perfectly when I listen to a voice memo (p.s. the volume slider disappears in a song page and even in the multi tasking bar)
Thanks for your solution, it wasn't quite what solved the problem but i remembered that i had a bit of salt water on my phone recently and spraying the charging port with an anti-oxide spray solved my problem, do you mind if i ask, how is the charging port related with the volume or/and speakers?

I was having trouble purchasing candy crush updates (for no apparent reason, as it has been fine previously). I thought perhpas I needed to download some new software and promptly started the IOS 6 update. It installed and then asked me to complete the final few steps by signing in with my apple id. When I try to do that it says "it cannot connect to the server". I have tried turing it off and on and over riding it, but it won't let me do anything at all now on my ipad mini.
Can anyone help? I literally can't function!!!!You can't override it no matter what you do. The device has to connect to the server to complete the iOS update. You could try rebooting the iPad and see if that lets you connect to the server after it starts up.
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.
If that will not work, you can try connecting to iTunes on your computer and see if the activation will complete. Sometimes when thes activation issues arise, you end up having to restore the device again, but first things first. Reboot and see what happens.
