Tecra S1: Notebook generates noise when the LCD display is on

• PCI-6733 signal noise when the computer screen is plugged, the weight on the case

  Greetings,

  I hope that it is in the right section.

  Card: PCI-6733

  I'm a 60 Hz, 2 mV peak-to-peak with a compensated 2.4mV noise when the monitor is plugged into the VGA port.

  Same card in a second computer, problem is more serious, 4mV Ridge to Ridge, 4.3mV offset. When I push on the case near the power supply the offset rises from a few millivolts.

  The two computers are running the same exact versions of software and drivers. Dell and quite similar to each other in both material and form.

  I have a third computer that noise coming out of the map is horrible no matter what.

  I exchange business cards and the problem is with the computer, does not follow the acquisition cards.

  No idea how to solve this problem and what is the cause?

  Thanks for any thoughts!

  Tall_Michael,

  Looks like you may be plugging your monitor and your computer in different points of sale.  If this is the case, this is probably the cause of your noise and can be eliminated by connecting the two devices on the same socket.

  Here are some articles that deal with the noise you are experiencing and various workarounds in the cases where what I mentioned above are not the case:

  The problems of noise in the measurement configurations

  Sources of the measuring Signal ground

  How to eliminate noise on measures DC power without using a lowpass filter of material?

  I hope this helps!

  Thank you

• Satellite L500 - high-pitched noise when the USB port is in use

  I have a Satellite L500-1ZP, aged from 1 month. When I connect a usb key or other device in my usb port, the laptop generates a high-pitched noise.
  The sound is not strong, strong but enough to irritate me.
  When I disconnect a device, the sound disappears.
  The sound is also there when I disconnect my laptop to the grid form.

  This is a common problem and can it be resolved?

  To be honest I don't think that this is a common problem. Is that what you found more threads with the same description of problem?
  The same happens when you use the available USB ports?
  You can locate where this noise is coming from? Maybe the speakers?

• Tecra A4: I need the LCD display ICC profile color

  Hello

  I have a Tecra A4-SP619 and I need the color of ICC profile for the LCD.

  Please, could you help get it?

  Thanks in advance.
  Sergio

  Hello

  I put t know why you need this profile, but to my knowledge you n t need this option to use the laptop properly.
  The Windows operating system and the graphics driver choose the right color management. You n t need to install anything.
  But still, in my opinion this information you will find in the manual of the user of this laptop.

• Super screen sensitive like I can't turn off the laptop and hear a clicking noise when the lid is closed

  I am running Windows 7 on a computer Tablet laptop of Dell Latitude (it has a touch screen that is not removable, but it turns). My problem is that I can not shut down this computer and carry it from one place to the other without losing all my battery power: you can hear 'ping' when the lid is lowered. If I have to carry that I have to turn off completely, otherwise it will just keep producing this ping and use my battery. Everyone knows this?

  This ping me makes me believe that a key is pressed, perhaps due to a letter from the keyboard that is stuck or is bad, or possibly a defect of the product.

• Select the list when the button display problem in Oracle Apex

  Hello world
  
  I use a button that displays a selection list box (contains two values) click on...
  
  Whenever the button is touched for the first time, the selection list box does not appear properly... the list box is displayed in a smaller size if the values it is not visible...
  However it appears correctly when I hit the button for the second time... its strange...
  
  Help, please!
  
  Kind regards

  There are two options. One is to create a Page process that fires before header or after and sets the value of the element. This method works when the value is independent of the other page elements. If the value is dependent on other page items, you can set all at once in the same process.

  Example:

  declare
    var_field1   VARCHAR2(40);
  begin
    var_field1  := :APP_USER;
    :PX_USERNAME  := var_field1;
    select COUNT(row_id) into :PX_USER_COUNT from users;
  end;
  

  This example illustrates two ways to define the elements of the page: one using another variable and the other as a result of a pass-through select query. You can also use the function calls, the application variables and more.
