I use an NI USB-6216 data acquisition and my held my load cell signal cuts out when I plugged into a laptop. When I unplugged the power cord, everything works fine. See the results below:

  • The top graph: unplug the power cord.
  • Average chart: full, connected power. (this is what he was doing before)
  • The bottom graph: 65% with power connected battery. (the thresholds are not as frequent)

Hi zgeorge30,

    Hi Hema,

    Thank you for your kind reply.

    I bought the system in a Dell store allowed, but the thing is I'm getting confused on post purchase experience.  The bag pack which the seller gave me apparently local, when I refused to take it, he assured me that I will get a real bag after a few days. I also think that I cheated from windows.

    I will be much obliged if you can read the issue in the context (the conversation with the windows community)-

    My question - what is the use of "slmgr / / ato" command, my system is watch a range error code 0x80072EF7, when I run this command. can be solved?

    response-

    Thank you for visiting Microsoft Community.

    According to the publication of the description and the error code that you get when running ' slmgr / / ato "command, it seems that you have any question in your Windows activation.

    Use of slmgr / / ato command:

    For volume systems, with a KMS host key retail editions or a key to activate Multiple (MAK) installed /atoprompts Windows to attempt activation online. Activate Windows license and product key from the Microsoft server. If you receive error 0x80072EF7 code then I suggest you to try the steps outlined in the article below and see if it helps you to solve the problem.

    My question-

    I can't run these technical stuffs on my computer. I'm scared I might lose the original settings since I'm not familiar with computer terminology. I didn't activate windows, I run the command "slmgr/ato' because of Microsoft technical team asked me to do the same. The reality is that I just bought a new Dell laptop, which came with no reinstalled windows, but dealer told me it communicates me windows 8.1pro as compliment (when I asked him which win. I should use win10 update or win original 8.1). and the cost of windows is not mentioned in the Bill. I was not aware at the time of the purchase that I won't have a preinstalled windows system, because I asked the price for laptop with the desired configuration and win8.1. I never thought that I buy a DOS system. I paid for almost the same price for laptop with "win 8.1pro" brokers in the area compare to preinstalled laptop computer sing.language win8.1. After 2 days, when I realized the question and asked the technical team at Microsoft to see if windows that is installed on my system is authentic or not, and they told me that windows is authentic, after checking with my key.  From there, my doubt starts Can a windows be true, even if the user has no evidence that he has purchased? Is the only information is the product key which certifies the genuine windows? What is the risk if the dealer gives the same key to another customer as a "compliment".

    Once I shared the issue with Microsoft support, they tried to hear me, but I think that they have not properly my concern. However, they asked me to run that command and message showed that windows is already activated. Since then, I thought that it could be someone else can also use the same key, I tried to check this order 4 days after. Since then, this error shows. Now, I want to solve each and every error on windows, I will also be very grateful if you could provide me the only way to learn how to check the real windows.

    response-

    Yes, I agree with you, your concern on the product key. It is true that your computer vendor could give the same product key to the other person as a gift too. If another person uses the same key to activate the OS, then you might get pop up to activate your Windows or other activation errors.

    You can see the article mentioned below to check if your OS is authentic.

    My question-

    Today, I called again to Microsoft helpline years technical support says my concern again. This time they told me that 'the ID of the product' which I use is enabled on other computers, but still found my authentic windows. I wonder, earlier the chat session which is held with the technical support told me that no one can use the same key that I use. If it someone trying to do it won't affect my computer because I am one who is authentic and the first user. I don't understand why are there different versions of the truths in the company for the same problem?

    I feel very sad that the company like Microsoft is not able to do something for their customers like me who are less sophisticated techno and want to become authentic windows user! Now, I think there must be a link any between the 'error', I've mentioned above and even the activation key on a different system.  I'm afraid how it would affect my system if other systems get activated by the same key. I don't know what are the services that I won't be able to enjoy if my windows become ingenuine later. Kindly guide me how to raise my complain about best way (with respect to the argument) to the dealer or authority be it is.

    response-

    If you have a valid key, then you will be able to turn it on again. If you call our support team then they will check into his tool and validate it, after doing this they will validate your key and help by activating the latter, if it turns out anyway.

    Keep us.

  • Pavilion G6 2005ax: laptop computer charger circuit problem

    My laptop HP G6 will not charge the battery and is not able to run with only one adapter. The charge LED lights up not at all. The laptop requires the battery to start but once it starts, the laptop is able to operate using the power of the AC adapter. I took it to a local service center, and the guy said that the motherboard has a short circuit and needs to be replaced.

    I decided to try to fix it myself. I used a multimeter and found that the power adapter and plug DC work correctly and give output 19.5V. However, when I tested the pins of the battery meter showed a power of only 2, 6V. I'm guessing that there is a problem in the load circuit. Can someone help me?

    Thank you.

    Hello @Prad3791,

    I understand that your laptop encounters a problem with the circuits on your computer to charge, and I'd be happy to help you in this case!

  • HP pavallion 15e019tx: laptop computer charger not covered by the warranty of 3 years?

    Mr President
    I pavallion computer 15e019tx hp laptop that I bought in September 2013 with 3 years on-site warranty for equipment. Now my chager does not work. When I contact support team, they simply said that the battery and charger are not in warranty!
    If we are given the charger with the laptop at the time of purchase and there is no separate additional charges for the adapter, then why we are asked to pay for the replacement, if we are under warranty!

    This means buying a laptop for around 40 k and then pay for coverage and then your charger is still not covered under the present... when it will stop working, you are to pay about 2 k more...

    one more thing

    the address for the authorized service centers and their contact details must be updated on dialy basis... you have no idea how much we - customers have to suffer...

    Sorry, but I'm really angry... to get to talk to a representtive through online chat, it took me an hour to connect... and then he said that you are connected to the usa... gave me the link for the number of teams and contact with Indian support (he was really friendly, which helped me). I waited two hours to connect to the chat Indian tech support chat online and then disconnected...

    What should I do now? buy a new one and tear up the papers and that Bill saying "3 years on-site warranty..."

    or wait for a miracle to happen...

  • I have 2 imacs and a laptop computer and you want to back up all three wireless via time capsule on my existing wifi network. If we can also use the time capsule as my wifi and replace my uverse wifi, that would be great. possible?

    I have 2 imacs and a laptop computer and you want to back up all three wireless via time capsule on my existing wifi network. If we can also use the time capsule as my wifi and replace my uverse wifi, that would be great. possible?

    If you want to make sure that you will be able to get the Apple support in case of problems or questions with your backups, you must use the wireless Time Capsule to back up your Mac.

    As long as the time Capsule provides a wireless signal, you can decide who to your 'main' network, then use it wireless Uverse for "guest", or children. If you do not need the Uverse router/modem wireless at all, it is possible to turn off wireless on the device and make it work only as a support modem/router...with Uverse wired.

    At this point, you can start thinking about how you want to configure things and get back in touch if you need some advice on how to do it.  We need to know what operating system that uses the Mac that you normally use to administer the time Capsule, provide good instructions, if you need it.

  • HP15-g088ca: HP 15 laptop computer purchased less than 2 years ago. Broken hinge, display cases of separation. HP, please help.

    My son uses his laptop computer HP15 home to his office, rarely transporting.  He never gave it and a sweet user.

    The left hinge seems to be broken / defective, and separates the window.  For now, we are all leaving the screen open all the time, but it's a little awkward and the problem is certainly on a laptop less than 2 years old.

    Looking at the forum, it looks like a common problem.

    We are fans of HP in general, so I hope that this problem can be solved.

    Help, please.

    -Steve

    Hooray!

    HP solved the problem free of charge, including shipping in both directions and repair.

    It took ten days in total, and we used the laptop without a problem for about 10 days more.

    It seems that the hinges for laptop and the display case were entirely replaced, and no data has been lost.

    My son is thrilled to have his laptop in return, and to my eyes, HP just went through.

    I wouldn't hesitate to buy another HP product, although I confess in the hope that:

    (1) HP manufacuring no longer uses defective parts

    (2) HP treats everyone with this problem of hinge with the same care

    Thank you and HP support HP!

  • Satellite A210 - 1 4 - failed to start the laptop computer just orange light

    OK, so this is what happened:

    While my friend was working on his laptop computer that she had his charger plugged but it did not load. I discovered that the lead from the Charger AC/DC had frayed and should resolidering. After that the laptop was working fine, I looked inside the laptop to check the AC plug connector before I fixed the cable.

    I noticed that the WiFi card was broke, so I changed it to a WiFi card in my other laptop used. After back the laptop together and put the battery in, the lights on the front flash blue only and the power light stays orange as if the laptop is in stand-by mode. I can hear the hard drive turns and the CPU heats more CD-ROM drive works, but I can't start that the laptop just sits there with the Orange.

    I tried out the CMOS battery, I took out the main battery and just used the AC/DC adapter, but the same thing happens.

    ANY IDEAS?

    Hello!

    I'm not sure, but what happens if you remove the WiFi card you created in? The new card is may be defective or not compatible with the laptop.
    You can start without WiFi card?

    To me, it looks like a hardware problem and your laptop should be checked by a technician of the laptop. Maybe the motherboard needs to be replaced or something else

    Hello.

    I just bought a new laptop of spectrum in the United States.

    I need travel in Australia for work. This portable US will be OK when plugged into power in Australia which has a different voltage (assuming I use a plug converter suitable).

    Also, do you know if it is possible to use a HP spectrum Australian power adapter so that I don't have to carry around one of these power converters ugly on the end of the plug US?

    Thanks in advance.

    First of all I live in a city called Melbourne (Aystralia) right now and my laptop computer loan spectrum is the United States (office of HP in Utah) and Yes, all I need is a tourist adapter as shown above.

    Second performance I see no difference, please note: we use 240V in Australia and the charger will be doing the work to convert AC current DC to run the laptop.

    However, you can try to set up a Wi - Fi hotspot on your laptop and check if your phone can spike the signal.

    The version of Acrobat provided with CS4 was Acrobat 9 Pro. Acrobat 9 Pro Extended was sold as a stand-alone product.

    If you already have Acrobat 9 Pro Extended, and then uncheck the option to install Acrobat when installing CS4, and you can continue using the stand-alone copy. Acrobat and CS4 don't actually talk to each other, so the installation of CS4 will not affect your installation of Acrobat unless you force the CS4 install program to replace it.
