Digital inputs only noisy when the laptop is plugged

I had problems with loops of Earth and power supplies for laptop in the past.  But it is the first time I got it so wrong that it makes the digital inputs which are both related to the ground and the debounced software cannot be used.

It is NOT material OR.  It's a DT9816 of data translation, a USB DAQ Multifunction with small budget.   The laptop with the problem is a refurbished Dell, with a very obvious not Dell PSU who throws to the top of the warning in the BIOS and scales back from the processor.  (Danger Will Robinson!)

The problem with the digital entries shows only upward on the Dell when it is plugged into a power outlet.  On all other machines and with the printer unplugged Dell, digital inputs floating.  But those that I have attached to the Earth is rock solid and work very well.

What surprises me is more than the noise is so bad that even tied to the ground with a half second debounce, I get always false triggers.  I have not brought to power, but considering that it sounds really loud, I suspect that it looks pretty bad.

I think I'll try a powered USB hub.  If this does not work, then I think that the customer will have to replace the power supply on the laptop.

However, I was surprised.  I used a lot of USB DAQ hardware, and it's the first time I've never seen a problem like this.  The NI USB 6002 I tested on this same laptop does not seem to show the same problems.  Even if it is true that this is a different software and the test was brief.

I'm curious to know if other developers have found something similar in the past.

I can confirm that using a USB hub external powered eliminated the problem of noise in the original post.

Interesting things.  I had not seen this before.  Now, I wish I had again the NI DAQ USB I had here last week so I could test that.

Looks like I'll use a hub powered on this project.  But I think I will recommend always replace this power.  Although a lot of noise coming from the power supply, probably isn't good for nothing plugged it... or even sitting near him.

  • CC only opens when the laptop not linked to internet

    When the laptop is connected to the internet Creative Cloud opens and allows me to launch Lightroom. However when the laptop is not related to internet, all I get is error screen that says I am offline and needs to connect to the internet again. It is not related to the day 30 'Refresh' which is required to check that my monthly payment has been processed. I use the Windows 8.1 operating system and CC build 2.2.129. The problem when the McAfee virus protection is active or disabled. What I've noticed is that sometimes when I start to creative cloud the "trial of the Star' button appears but when I click on the program solves the problem when I open Lightroom."

    I spent hours on the phone and via the Adobe Support chat link and they can not get this to work. I even they gave remote access on my device. I've seen other posts in the same direction, and despite the suggested fixes, the problem persists. It becomes very frustrating because I'm doing wildlife photography and it's a challenge when in the African Bush with no connectivity.

    When not connected to the internet, please try running the installation location apps.

  • should I take out the battery when the laptop is plugged in

    Hello everyone, starting here. I have a question about my hp dv7-4274nr laptop... I said, when you use the computer should I take out the battery when it is plugged in to the 110 (ankle) is this true?

    Thanks Mike

    No, the only reason would be if you use the laptop on the sector for a long time, like a month or more, then drain the battery in 30-40%, and remove, store in a cool place.

  • When you import images in LR5 on my laptop, the photos all have a broad yellow streak through them. This only happens on the laptop; I can import the images on my LR Office and he's not the streak of color.   Can anyone help?

    When you import images in LR5 on my laptop, the photos all have a broad yellow streak through them. This only happens on the laptop; I can import the images on my LR Office and he's not the streak of color.   Can anyone help?

    This happens even with pictures taken on another device, not just mine.  My daughter told me that the phone fell recently.  The yellow streak isn't nowhere elsewhere on the laptop, right on the photos in LR.

    It happens when you import new images. This pourrait indicate that the sector where the pictures are copied to is damaged. But it could be a faulty card reader or a bad cable if you connect the camera directly to the computer. It's a hardware problem. Your challenge is to figure out where this problem.

  • Satellite Pro L650 - 1 L 4: battery will be discharged when the laptop is disconnected

    Hello together,

    I have a problem with my 5 month old laptop Satellite Pro L650 1 L 4.

    When the laptop is unplugged it will pay the battery. About 44% within 24 hours.

    Of course, options like BIOS "Wake we Lan ' and something like which are completely disabled.
    And of course the laptop is turned off completely and not the Sleep Mode.

    Any ideas?

    Kind regards

    Stephan

    Hello

    Please check if the wake-up on LAN is also disabled in the properties of LAN card (Device Manager-> LAN card-> properties-> Advanced tab).
    I also recommend checking the WLan card as well.
    Please also check if attached USB devices don't lose the power of the battery.

    But also a malfunction of the accumulator may be possible... so it has to be checked also...

    Hi there @lisanvo,

    I looked into the different ways that you can use your laptop to see if the function to the HP ENVY x 360 on its side in laptop Mode was possible. I found a paper called HP ENVY x 360 Convertible PC - Maintenance and Service of Guide.

    If you look under external component identification on page 7, , you will see that it gives you three modes that allows this particular model.

    I also found that the tilt sensors and the dock will not to allow you to use that phone in particular in the service that you want to because it's a model that allows you to have capabilities of the tablet.

    I want to thank you for visiting the Forums from HP Support.

    Have a great day!

  • can you use a deskjet 970cse in black only mode when the color cartridge dries up

    can you use a deskjet 970cse in black only mode when the color cartridge dries up? Thank you, Jerry

    banhien information is very accurate. I would just add a bit of it. Because this printer uses a tricolor cartridge and a black, it should be one of the printers that will print with just the black cartridge installed. It is called print in backup mode. I should happen automatically when you remove the color cartridge and try printing. A message will arrive on the printer or the computer and ask you if you want to print in backup mode. Say yes, and it should let you print. Hope that helps.

  • PDF forms have problems displaying text and only appears when the field is selected

When they work as a team, the pdf they receive from a third party often appears limes or no text, the text is only visible when the field is selected. I need to find a solution for this, because our company's products are based on this form.

    If there is any information addition that I must add to understand what is happening and how to fix it, I'll be happy to write it.

    In society, we all have mac and forms where innitially created in Adobe acrobat 9 pro, but we now have Adobe acropabt pro XI.

    Users of Mac and Windows systems.

    Thank you

    This is usually caused by the form is filled out and saved by a Mac user who uses the preview application to view the PDF file. More information is here: http://kb2.adobe.com/community/publishing/885/cpsid_88564.html

  • How to get a popup when the device is plugged into the audio input jack?

How do I get it to appear again? I have Windows 8, with player realtek HD audio. More info can be provided.

  • Satellite A300 may depend on from when the power adapter plugged

    Hello

    I have a problem with my Toshiba Satellite A300 when the laptop is connected to the power adapter I have no possibility to turn it on, it's only 2-3 seconds once it comes down.
    When Toshiba is enabled with the battery power and I tried to connect the adapter it also goes down.
    I have no problem with the charge itself, but only with working with AC adapter.

    Please help me what can I do with this problem, does anyone has similar problem?

    Hello!

    For me it sounds like a hardware failure of the motherboard if the AC/DC adapter is plugged and the laptop is turned on

    I don't know but how best to m would be if you go to the authorized service provider nearest with the AC/DC adapter. Technicians can check your laptop and swap the motherboard if it of really necessary. The guys are very friendly and helpful!

    Here, you can search the nearest ASP:
