More sensitive touchpad? Vibrating and shaking cursor?

TouchSmart tm2 2010eg. Sometimes the cursor starts shaking and vibrates a little, sometimes when I flip the screen, sometimes just like that. If he does, I can literally "throw the cursor on" shaking the computer. If I move the computer, the cursor is still more fragile. When I then make a very rough gesture to the slider, like putting my hand flat on the Panel, the shaking may stop.

I am still under warranty, is it a hardware problem I should require HP Technicans set?

I noticed that the problem occurent more frequently when the screen is completely reversed, so I thought it must be electricity touchpads interfering with the capacitors of the screen. Turn it off with the appropriate command (synclient on Linux) has solved this problem.

I still want to know HP if it is expected behavior and that the newer models have the same 'problem '.

Thank you.

    Original title: replay Vista operating system

    What I would like to know, is my computer only has a black screen and a cursor, there is no menu start, so I can stop and start a new installation of windows vista? If anyone can help please. I thank you very much for your time and have a fantastic day. Shawn

    Hello

    What changes have been made on your machine for there to be a black screen with a cursor?

    Rather than doing a clean install of your operating system, I suggest you do the following.

    Step 1:

    Remove all external devices (printer, USB flash drive), as appropriate, and start your computer again and check.

    Step 2:

    If this is little help, start your machine in safe mode and check if it starts on the desktop.

    Let us know the status of the issue.

  • Touchpad on my HP Mini 110-1125NR is locked and the cursor does not move

    I've never locked my computer.  Everything has been implemented in the store where it was purchased about 4 years ago.  I put my computer in sleep mode yesterday afternoon and just tried to use this evening... somehow, the touchpad is inadmissible and the cursor does not move.  He remains in the middle condition of the screen.  I turned off the computer and restarted, nothing done.  Can anyone provide a solution?

    Hello

    Shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    If the pointer is still frozen, try double clicking the top left of the button.

    Hey Nishya12,

    Thank you for using communities of support from Apple!

    From what I read, it seems that your iPhone on iOS 9.3.3 5s is not cling your text/iMessages. I'd like to keep track of these conversations myself I'll be happy to help you.

    Because you used the link at the bottom of the use of Messages with your iPhone, iPad or iPod touch to get more help, I'll assume you have check the Messages on your iPhone settings. If you do not, click the link and check that everything is configured correctly.

    iMessages is part of the iOS on your iPhone, in order to have this behavior as you described refers to a problem with the installation.

    Save your iOS device - install a new clean copy of iOS on your iPhone, is what we call here. Since this process will erase everything, I highly recommend making sure your personal data is safe to backup and first.

    Use iTunes on your Mac or PC to restore your iOS device - to install a new copy of iOS, your iPhone will be erased completely and that cannot be done via iTunes on a computer. In the settings of the iPhone doesn't that erase your personal information.

    Once your iPhone has rebooted, you will configure your phone as a new iPhone this time. If you wish, you can connect to dive into iTunes and App Store and iCloud. At this point, check iMessages and see if it keeps your messages after they are sent. If so, the next step.

    Restore your iOS device from a backup - now you're ready to bring your information to your iPhone. Just follow the steps described in this article.

  • P300-sensitive keys unresponsive and stay on even when laptop turned off

    Hello

    I have a P300 - 18M and the sensitive keys has suddenly stopped working, none of them are to be pressed (usually the light goes on).

    So I rebooted, and they were always the same. I can stop the laptop and the fires remained, even when I unplugged it.

    I then disconnected the battery for a minute, put back in, kicked upwards and now the buttons work correctly once again, however, I wonder, I would do anything to this topic, because my warranty runs a little more than a month, and I don't want to break right after...

    Also, anyone else has experienced something like this?

    Thanks in advance

    Jack

    Hello

    It's really strange question, but if it works again, so I don't think that there is a serious problem.
    Of course, you can call Toshiba nearest service and ask for help, but if everything works well again I think there is no reason to panic.

    Service can test with own preinstalled OS and if everything works fine you will answer for laptop.
    Play a little with these buttons and features to test to be sure, everything is OK.

  • Screen is scrolling down repeatedly and the cursor moves on its own.

    The cursor is rolling along of type I.m

    You do not give much information about what is really happening, but the first two points to check are the mouse and the keyboard, before looking for other hardware or software problems.

    If you have another mouse and keyboard available, you can try reverse the two and restart the computer to see if the problem persists.  If not a little more information would be needed before I could give advice on the best way to solve the problem.

    You're talking about the screen, scroll down and the cursor moving without the mouse - these are two separate actions.

    He is not anywhere on the screen do scroll down unless you have a running program - this scrolling happens with all programs that could scroll, or simply with a certain program?

    The cursor moves randomly or according to a specific orientation?  The cursor move around all the time or only in certain programs?

    These problems occur all the time, or only when you do something, like click with the mouse or use the scroll wheel?

  • the pen he more sensitive?

    Hi all. Currently meeting using class Notes to take notes and all of a sudden pen seems to be super sensitive, makes the lines on screej when not even y touch and - worse still - joining lines all points as if the pen never removed from the screen. very strange. Looked like settings, played with the hardware and software settings, he can't get back to how it was. After an hour spent at Quill and find the same problem here! am I crazy? I put tpt do 20 + updates last night, something that touched or my game with my pen/battery (which I was) somehow it made more sensitive?

    Thanks in advance,
    Rob

    OK, it me - fixed using pen... pretty odd out, so be aware that how you put your pen set may affect his sensitivity... [last time I do that..]. Apologies for the noise (mostly useless).

  • My trackpad will not move my mouse and the cursor will not click or give any indication that she works

    I got my new TOSHIBA Satellite laptop for about a month, and all of a sudden, as soon as I sign into my account from Microsoft, the cursor either disappears or said and stops working. It will not go with my trackpad, an indication that it is active, due to the fact that the mouse goes down on the tiles Metro UI normally, but don't highlight. On the trackpad buttons do not work as well.

    I had this same problem happen to me. I have a Toshiba Satellite C855D-S5315. I went to the Toshiba, and click Virtual Help Desk Web site. Immediately options pop up, and you'll see the option "The Touchpad does not work". Click on that and it will take you to the appropriate page. Start with the first option. That's what fixed it for me. If you can't get on the internet, that's what it says to do:

    Enable/disable the touchpad, do one of the following:

    • Press the button to switch on/off touchpad above the touchpad.
    • Hold down the FN key and press F9 .
    • Press the touchpad button (F5).

    After that, my touchpad worked.

    If it still does not, have the rest of the solutions say:

    Try to uninstall the touchpad driver and restart your laptop:

    1. Vista and Windows 7: Open the Start Menu and type "Device Manager" in the search field. Select "Device Manager" in the results.

      Windows 8: START screen type "Device Manager".

    2. Select Device Manager > mice and other pointing devices > right-click on Alps Pointing-device > select Uninstall.
    3. After that uninstall the driver, reboot your computer. Driver will be installed automatically.

    If this does not resolve the problem, try to perform a restoration of the system to a date before the problem occurredCLICK HERE for an educational video on the restoration of the system.

    If the touchpad is still not working properly, the laptop needs to be repaired.

  • When to use the cursor for loop and the cursor (open, fetch, close)

    Hello world
    I have a small doubt about when to use the cursor for loop and when to use the cursor for loop and the cursor (open, fetch, close).
    Well, I'm not the difference between implicit and explicit cursor. So please tell me how I got to know, what to use and when?

    All SQLs are analyzed, stored and executed as cursors. Thus, you will always use a cursor.

    The problem is that languages, such as PL/SQL, provide different interfaces to interact with the SQL cursor. As the ref, the slider interface, the interface DBMS_SQL slider interface and so on.

    Each of these interfaces offers different features. For example, using the interface DBMS_SQL allows binding dynamics and dynamic recovery. The Ref Cursor interface allows your code PL/SQL pass a handle to a reference pointing to the SQL cursor, to an external client. Etc.

    The fundamental reason for the use of an explicit cursor interface is mainly that you own and manage bulk made extraction output provided by PL/SQL cursor.

    With a cursor FOR , the motor loop of PL/SQL optimize the loop by extracting block a 100 lines both. However, you cannot access this collection in bulk directly inside the loop.

    With an explicit cursor interface, you specify the size of the extraction in bulk via the clause LIMIT , and you set the variable of collection to use. This allows you to use the collection directly variable inside the loop.

    However, the need to do - code manually in bulk collection - rarely occur in the daily programs in PL/SQL. A line of treatment is both slow and not well fits. And even if your bulk code collects lines, these lines must still be processed one at a time in your code. It is much more efficient and scalable rather write SQL code, and make the engine SQL the line of treatment for you.
