T400 switch to touchscreen?

Similar Questions

• T400 - switching graphics and many wonder

  I just got T400 for my school work. I understand there is also a feature to switch between integrated and discrete GPUS.

  I have a few question now...

  In Device Manager are we suppose to see two installed GPU, or just one active?

  What are the conditions for Manager power switch between two GPUS?

  How can we explicitly make the switch without according to conditions set by the power manager? I have read the help file, I had no option to the power gauge to move the graphics.

  It is also remarkable, although there is a manual for this laptop, it's not detailed enough some of the function which is pretty new to me. for example, it took me a while before I know how to configure the fingerprint for log reader. The use of the scanner is not covered in the manual.

  And I can't use the function under thinkvantage to get expert help. There continue to be "Internet Explorer cannot display the page" firefox/opera/safari not so.

  I thought about it.

  My school uninstalled, the function by accident.

  For those who cannot always make the switch, just look at the taskbar, there should be a gauge of plug or power. Left up until it clicks, it will give you a menu with "Switchable Graphics", do your stunts there

  The function is not found anywhere in power management. It's a little weird, like the help file on the hood of management this function. The team of documation fails!

• KVM switch with touchscreens

  I have three computers on a KVM switch (two using Windows 7) and the other using Windows XP.  I would like to install Windows 8 on one of the computers and to install a touchscreen, but do not know how it works via the KVM switch.  I understand that Windows 7 can use the touch screen, but it can pass the switch connections KVM mouse?  How Windows XP, which is my file server run even if she cannot use the touch screen features?  I guess I have to use the classic mouse.  I just let the mouse on Windows 7 and Windows XP only systems connections and use the touch screen for the Windows 8 only?  Not much on this subject.

  Windows 7 and Windows 8 have support integrated touch screen features so that you do not need to load special touch screen for these two systems driver.

  The issue will be on the touch screen, you will use the 'pilot' for the XP system or not.  You should check with the manufacturer of touch screen and ensure that they have the driver for the XP system.
  In addition, if your KVM switch is based on technology "emulation keyboard and mouse", then you can change your class KVM "DDM (dynamic device mapping)" switch the KVM switch that ensure that your monitor touchscreen works smoothly with all the different BONES connected to the KVM switch and with no latency in the passage.

• T400 will not recognize Benq monitor through my KVM TRENDnet switch

  I get an error message "your computer is not connected to an external monitor" when I try to connect to my analog monitor via a KVM TrendNet 4 ports (TK409K) to my T400 switch... USB keyboard and mouse over his fine thru the KVM switch... jobs on the other ports (a NetVista and a ThinkCenter) all work are all OK and can use the monitor correctly...

  My laptop prior (T41p) was also able to use the monitor through the same port of the KVM switch... only change was to replace T41p with upgrade to T400... If I ignore the KVM switch and connect the monitor directly on the T400, everything is OK.

  I thought that the laptop monitor output was only outgoing, but the error message seems to indicate that there is a way to detect if something is attached to the monitor on the T400 output connector. My suspicion is that some info the T400 expected when a monitor is attached is not return through the KVM switch, but...

  Ideas, advice, advice would be greatly appreciated... thx in advance.

  Problem solved (well, I guess it's really a work-around)...

  a cable DVI - D my laptop docking to my double-entry screen allows me to get the video signal directly and get the entrance of the kbd and mouse through the KVM switch... and my two offices continue to function through the KVM switch to the analog input of the monitor

  I never knew which signal was not passed from the monitor to the laptop through the KVM switch... but the laptop did not recognize clearly that there was a monitor attached through the KVM

• Pavilion 17-e040us: can I switch my laptop no touchscreen touchscreen?

  My customer told me it was a touch screen, that's what I ordered.  HP 749970-001 touch screen display Assembly.

  It is installed, but not recognized.  To use it as a touch screen, which had to replace the motherboard too?

  Is there a driver?  The display works, it does everything just doesn't like a touch screen.

  Sparky

  While studying the question of the touch screen, I stumbled on what is called the closure of two buttons.  It is mainly for the Surface, but some have tried with success.  He is pressing the power button and the Volume Up (key F8) key at the same time immobilized for 15 seconds. This does not work with my machine.

  The initial point of this project was to get the machine working again.  Replacement of the screen with a touch screen, or disassembly of the old screen and replacing the video cable or LCD could be fixed.

  Now I have a working, no touchscreen machine.  I would like to know if replacing the motherboard with one that supports the touch would work.  Are the existing BIOS chip and the motherboard a pair?

  What I learned from this project is that if a client tells you that it has a touch screen, do not believe him.  Go to the manufacturer's website, enter the model number and check the specifications of this model, see if there is no tactile or touch.

  My client talked about this mousepad, not the screen.

  I also learned that you can't do a non touchscreen machine in a touch machine by replacing the entire screen with the correct number without touchscreen part unless there are secrets that no one shares.

  On the Forum, if you don't mind, I'd appreciate that you would leave this discussion open a bit longer, just to see if something is posted on the BIOS and motherboard.  The project will be comlete if I succeed in replacing the motherboard.  The project is considered to be a failure if it is not an option.

• Disable the touchscreen for TouchSmart HP ENVY 15-j173cl Notebook PC

  The laptop:

  HP Envy TouchSmart 15 (15-j173cl) PC notebook

  Windows 8.1 Pro

  The problem:

  I use an external monitor, so my laptop is usually closed.  Randomly, my touchscreen think something is in contact with her, which disrupts everything I do.  I would like to completely disable the touch screen, because I do not use it.

  I thought that maybe the lock was not shut down properly, but the screen resolution changes when I close the laptop, so that it KNOWS that it is closed and switches to the right resolution for my external screen, but it IS NOT to disable the touch screen, and little land or something is in contact with it, changing where my mouse is pointed where I type, etc.

  I tried to clean the screen and the keyboard with compressed air.

  The problem occurs randomly; Sometimes, when I'm CAD for the day, sometimes after hours of work.

  Hello, @rockspeak
  
  Welcome to the HP Forums.
  
  I see you want to disable the touch function in your display for portable computers. I will help you with that.
  
  You can do this by going to Device Manager > click on the + or > by Human Interface Devices > right click on the touch screen to HID-compliant > choose disable. This will have disabled the touch capability.
  
  I would like to know if it works for you.

• Can Portege Z20t - I disable touchscreen?

  Hello
  I have a z20t-B-107. Beautiful machine, upgraded to win 10, all working very well - I had to download a new driver from Wacom to get the "left click" to work with the pen.

  I use it in tablet mode to scan a few data points on a map and sketching with pen. However, when I rest my hand on the screen it 'active' the touch screen and makes things go crazy. I really need to temporarily turn off the touch digitizer and have only the Wacom digitizer running, and if I can switch it switch somehow, that would be useful. Otherwise, I need to use the stylus in a very natural position to avoid touching the screen with my hand.

  I have a Samsung Galaxy Note, which uses the Wacom type digitizer - it does not seem to suffer from this, as soon as it detects the pen close to the screen it seems to cut off the touch part.

  I would be grateful for any help - I tried to search engines, but only, they seem to give results on the touch keys, and it's completely different...

  Thanks in advance

  Hello

  I use a Z20t too (but with Win8.1) and have the same problem. I decided to cut the full contact. It is not a good solution, but a good job with OneNote is only with the deactivation of the tactile feature possible.
  This is perhaps a possible solution for you.
  In Win8.1, I turned off the driver in Device Manager.

  I found here as follows:
  http://answers.Microsoft.com/en-us/w...d55591d?auth=1

  1. right click and select 'All the Apps' in the lower right corner, and select Control Panel
  2. Select hardware and audio
  3. Select Device Manager
  4. Select Human Interface devices
  5. in the list, find the driver for the touch screen. This can be difficult, since on my tablet that they are all listed as "USB Input Device" and there are 3 of them. I found it in deactivating and then reactivating one at a time until the touchscreen unresponsive. You can also identify the touch screen by checking the properties | Details and get the "hardware ID", then do a search online to see what the device is. In my case, the touch screen has the ID USB/VID_0EEF & PID_7302.
  6. Once you know which is the touch screen, disable the driver and the touch screen should no longer work
  Enable this device to make the touch screen work again.

• T400 own install problem for the graphics card hybrid

  I did a clean install on the T400 and installed all the drivers that are essential under the SWTools folder, but I see a problem with the card ATI will not work correctly.

  After installation from the folder videos and restarted the laptop. There is a sign next to the 'ATI Mobility Radeon HD 3400 Series' in Device Manager

  Any suggestions on how to fix this?

• Lenovo T400 again with windows vista

  I have a Lenovo T400 with Windows Vista and I would like to upgrade to Windows 10.

  10 free update Windows suddenly appeared in other laptops I own (even on machines T61) but it seems that there is no upgrade path to Win10 of Vista, it does Win7/8.

  Then... I know that I can buy a license key for less than $20, but I wonder is there an official way to improve this machine from Vista to Win7.

  Which is still possible?

  Thank you!

  You can still use switchable graphics, however it is not the easy way. You would have to use the BIOS to switch, and then the right video driver loads, depending on the chosen graphics chip.

• HP Pavilion x 360 m3-u001dx: touchscreen scrolling does not not on Pavilion

  Hello!

  Recently (in the last week or so) my touch screen acted upward. Sometimes I can click on things - such as switching between the tabs. But sometimes, when I click it will highlight a word on the screen instead of take me to the link I want.

  In addition to this, I'm completely unable to scroll using my touch screen. I have to use the mouse pad or the keyboard arrows. I am still able to use the mousepad for everything, it is so that the laptop does not work, but it's annoying that I can't use the Tablet mode. I bought this model so that I can use it in mode Tablet and laptop.

  I would really appreciate if someone helped me to solve this problem.

  -If I use the ATI catalyst software to set the resolution, I can only chose smaller resolutions (he not go 1920 x 1200)
