Touchscreen unresponsive on Portege M750 Windows Vista SP2

Have very old tablet Portege that I use for teaching.
Recently, I have 2 questions.

Fn + F5 first stopped working (used to operate through different display options and now does not work)
It will work with some projectors light up the computer when you are connected but not others.
Have tried all the options of mobility control panel of configuration/windows nothing helped.

Especially the touch screen no longer meets your finger or the stylus.
If I open the windows journal and try to write the name of the file and the options of the menu just gray go and the cursor disappears temporarily.

After a few seconds if I wiggle my finger on the mouse cursor pad reappears and if I then click on the button of the mouse menu options can be selected again, but as soon as I try to write the same thing happens.

I checked that all the Wacom drivers work correctly and up-to-date and that the pen and input device settings are correct - please help!

Hello

To be honest I n don't know why the Tablet feature stopped working but I suppose that its software problem and fix it by reinstalling driver/software.

First of all I recommend you to uninstall the following software components:

With the accelerometer, your machine will be able to detect how you're holding it at one point. You can set the machine to perform a specific function when the device is tilted quickly left or right, either at the front or back. You can also take control of the cursor in some applications and move by leaning the PC in a certain direction.

_Dual Driver_ touch

After the mentioned tools have been uninstalled, restart the laptop, clean the system using a tool like CCleaner 3rd.

    FSX is not started after that I applied Windows VISTA Sp2. When the process is considered to be a task manager, FSX.exe seems to CPU to make loops. Are there not the method to solve something?

    Hi BuyIntel,

    Thanks for posting on the Forum of answers.

    I suggest to backup your saved games and reinstall the program.
    Something in the Service Pack may have corrupted some aspects of FSX, this should solve it.

    I suggest also to visit your video card manufacturers website to download the latest drivers and re-installation of the unit.

    I hope this helps.

  • Impossible to update Microsoft Windows Vista SP2

    I have a laptop that is running Windows Vista Service Pack 2 from Microsoft yet. I have not started the laptop for almost a year and I understand that the operating system is no longer supported. I'm just trying to get all the other updates carried forward after November 13, 2015. The update of Windows seems not to be able to get updates or is suspended. In the past when Windows XP support ended, I was still able to update the o/s to the last update available for the well type beyond a year after. I don't see why I can't still not updated for Windows Vista SP2.

    I need constructive responses to solve the problem and not the usual, "my computer is old and needs to be upgraded or replaced", remarks. I don't have the funds to keep the upgrade for the latest and best. The laptop, I always work and if I have funds or if I know that it can smoothly run Windows 10, I could upgrade the o/s.

    Follow these steps: Install KB3078601, KB3109094, KB3145739, KB3164033, KB3168965 and KB3185911 manually. Download links:

  • Error 0x8007045D when you try to install Windows Vista SP2

    Hello

    Currently I have Windows Vista SP1 and want to upgrade to service pack 2. When I try to do the update of Windows, I get "error (0x8007045d) Error_IO_DEVICE. I also tried to install it in safe mode, I get the same error message. After having traveled a bit on the internet, I found that it is probably because my HDD is damaged... so I run the chkdsk program...

    The chkdsk program stops at 16%... Step 4 of 5... When 85785 files off 300000something files are done... and it does nothing more. It keep running like this all night, it goes no further.

    Does anyone have any suggestions on what I need to do to successfully install Windows Vista SP2?

    Thanks for your help!

    OK, I started the computer with the Windows CD and I ran chkdsk /f at a command prompt.

    Chkdsk /f found errors it corrects.

    I ran Chkdsk/r... .he got stuck after scanning 85763 files... near the place, he would always get stuck (85785 files)... so I guess it's the same file that crashes chkdsk.

    The good news: I still have a functioning computer.

    The bad news is that I ran the SP2 from windows update in new safe mode and it didn't work... I'm still stuck with my problem.

    I have an extra hard drive... that I ordered from Dell for my girlfriend's computer, his computer died before she could use the player, but it is larger, then the drive of your computer and it is brand new... the only downside is that the player has been implemented for the computer of my girlfriend (pilots and other things) and does not work in my computer. I guess I'll try to format that drive to make it work in my computer... it should fix this and then bad SP2 remedial power very well.

    I guess I have no choice.

    I suggest to remove avg (uninstall) then try sfc/scannow then chkdsk /f several times. a few times, they need more going to make things more

    Microsoft security essentials is a better a v for not update couseing problems.

    You can allways put avg in the back.

    not having is not enouph to free space for temporary files can couse problems too.
