• Satellite A200 - 1 M 8 and the second HDD bay

  Hallo, I want to install a second internal HDD to hdd2 Bay, but when I opened the Bay I noticed that it is not all connectors installed.
  So, what's the point of a second drive Bay hard if there are no connectors inside?

  Hello
  The point of this Bay is, IF you buy a model with a second equipped HARD drive then there will be a connector, but if bought a model with a SINGLE disc fitted then you just need a drive since the connector to the second HDD was not soldered on the motherboard of your model.

  Easy and simple. If you want to have a second drive, then you must either:

  -solder a connector for the motherboard which causes your warranty and does not mean that you can use a second drive since you will need the appropriate BIOS Rom
  -buy a USB - HDD and accept your situation :/

  That's all.

• 15-20 time of latency to see the changes in analog inputs

  I inherited a program extremely complex.  I find that I see 15-20 seconds latency on the changes to the analog inputs.  I can't post the code - (it has more than 200 sub screw) but I have captured the relevant section in the long latency period of the changes.jpg of analog input attached.

  I tried to change the sampling rate and see the same problem from 1 Hz to 25 Hz (limit of reliable sampling with this PC).  I'm looking at indicators which are directly related to the acquisition of data Read.vi as evidenced by the big red arrow.

  I modeled the nested struct in the template attached without latency problems.jpg.  There is no perceptible latency but it duplicates the nested structures.

  The only thing not shown is that there are several cases of Read.vi of data acquisition using the same physical changes but not of them are in the loops that need to run at the same time.

  The data are consistent with the entries, just delayed.

  The Signal processing device is a USB-6343.  I am running these screws on LabVIEW 2011 edition.

  Any ideas?

  Yes, instead of getting just 1 sample buffer, try to get all the samples.

  Then you can retrieve the most recent example of all the samples you get and take the rest of them.

  Or you can change the configuration of taks for only once every time that you call the read function.

• NOR-6289 DAQ latency for the generation of digital signals

  What I want to achieve is less than 1 second latency between the update of several digital waveforms and see these values appear on the digital output pins.  For example if I have 16 digital output channels in my task and I am writing 127 samples for each channel at a rate of 1 every 10 ms sample, then I update the waveforms in Labview that are sent to each channel, I do not see the new values on the pins of the output for about 21 seconds.  FIFO size onboard for the 6289 is 2 047 samples.  At this point, I guess this latency is unconstitutional by the FIFO on board - but I could be wrong.

  If the FIFO on board is shared by all channels in a task, a sample of each waveform is generated to the output every 10 ms, then I would expect latency (2 047 samples/16 channels) * 10 ms/sample = 1.27 seconds.  However, I still see latency of approximately 21 seconds. Is there something fundamental about the FIFO on board I'm misunderstanding? Or is there something going on in the PC buffer which adds this latency?

  I enclose my VI for reference. NOTE: The attached VI only has 2 channels for simplicity again it shows the same latency as the example on channel 16. I had a loop analog acquisition as well to monitor outputs from the digital PIN.

  Thanks in advance.

  The FIFO is not per channel, each line is a little and FIFO stores all of port 0 as a single sample (the lines that are not used in your job are hidden and not updated).  If your sample of 2047 THAT FIFO clocked @ 100 Hz will take roughly 20,47 seconds to build completely.  There is also a FIFO in the software (the size of it is configurable) which stores data before their transfer to the device.  The pilot will always try to keep the complete material if there are data to generate, FIFO which is good to prevent cost overruns but bad for latency.

  If I have LabVIEW 2013, I have not installed on this PC and so I can't watch your VI.  I'll try to give some suggestions anyway...

  One way around this problem is to use non-regeneration (not sure if you're already or not) and to limit the speed at which you write to your task so that the FIFO is never complete (once the data is written to the device, you cannot remove it from the FIFO).  To limit the write speed, try to look at Total "samples per channel has generated" (I think it updates quite frequently on the useful USB devices) from the "current write Position.  Both are DAQmx writing properties.  Only write data to the task when the difference is less than a threshold.

  You might consider the inverse would be output just at a faster pace with duplicate data.  For example, [1, 0, 1, 0] @ 100 Hz = [1, 1, 0, 0, 1, 1, 0, 0] at 200 Hz.

• calculate the time in seconds, the day of the year and year

  I have a data file where they record three columns, the seconds elapsed since midnight, day of the year and the year.  I am creating a timestamp of LabVIEW from these three numbers.  Of seconds elapsed since midnight, I can create seconds, minutes and hours.  If I feed in a cluster of time with the day of the year and the year, the timestamp of output is 0.  Does not work.  Although an input of the day of the year element, the Date and time with seconds function apparently requires day for months and months to work.

  The only solution I can imagine at this stage is to calculate the month and the day of the day of the year, which would imply a choice of the month table and a check of the leap year.

  Smart solutions, I'm missing?

• videos on web pages stop playing after 5 seconds

  I just installed Windows XP Home Edition on an old Dell (Dimension s 4500) computer.  Most things work well; However, I notice that all the videos on websites play for about 5 seconds and then stops.  The full video continues to be downloaded and can be restarted by clicking on a different location on the timeline - after which he played for 5 seconds.  This happens with Internet Explorer and Firefox and all the sites I've tried.

  It seems I missed some setting somewhere.  Any ideas?

  Duplicate content of the wire-
  "Earlier, I posted a question on playback of videos from web pages (" videos to stop web pages play after 5 seconds '). " Since then, I have studied the possible fixes on Windows sites as well as the Dell support pages (the computer is a 4500 s Dell dimension running Windows XP Home Edition). All responses/advice found do not seem to solve my problem. All drivers and all plugins are here and up to date. The problem is not caused by lack of bandwidth or buffer - download videos at a reasonable speed. It's just that they will play only about 5 seconds. Then they stop and not restart by themselves.

  In addition, the videos have played very well until I reinstalled Windows XP from a boot disk, so I'm sure that all the works of material.

  It's driving me crazy! Can anyone help? Please, I beg you! »

  I wonder if it's a snap in IE and Firefox. You can try and disable them and see what happens.

• Why Responsive mode Design might disagree with the box of the HTML element model?

  In the web page, I am writing right now, number of width of the sensitive design view does not match the width specified in the view of the box model (meaning that my questions of media do not seem to be triggered the breakpoints of good width). See the attached screenshot that displays the Appointment page, view the box model and a ToolTip with dimensions of the HTML element.

  I have yet to reproduce it in a simpler page, although I'm still trying. I dismissed the possible influence inland iframes and the viewport metatag.

  So, I would like to know what could cause two tools to account for the figures of different widths.

  Ah, I tried using 38.0.5.

  This could be a problem of zoom?

  Oh! That's all! I was slightly zoomed-out and after a Cmd + 0, RDV now accepts exactly with the box model, and queries of the media are behaving as they should.

  Quick Note: the zoom was causing a second problem, since she has been scaling 430px for a number between 481px and 480px wide, triggering neither of my media queries (which had max-width: 480px, the other min-width: 481px). It was almost as confusing as the numbers is not the first place.

  Thanks again!

• How to restore unrolling of the window of the menu?

  I've a dropdown menu with exit and other controls window. I now work on this during several hours and lost all my previously saved windows and labels for the second time since Firefox updated itself.
  I can possibly be working in mode 'safe '? Help, please.

  You find the "Open Menu" button, which has 3 bars, on the right of the Navigation bar?

• What is the best micro sd?

  I was looking on the Micro SD that better suites my Titanium, really, it uses a Micro SDHC card up to 32 GB, but I also want to know the class of the SDHC, can someone help me on this?

  Thanks in advance.

  Today, I learned about the microSD, after asking the Motorola Live Chat support:

  • Brian: Renzo, in general, all of our Android phones that support microSD support SDHC cards (secure digital high capacity); SDHC refers to the ability. Most phones can support up to 32 GB of capacity SDHC SDcards.
    Android also supports high speed SDcards. High speed means that the bus runs up to 50 MHz, which is 25MBytes per second. A rough understanding of the system class, is MB per second. If a Class 10 card will write up to 10 MB per second. Since the bus high speed transfer of data up to 25MBytes per second, we support a class up to 25 class (when these are available). Class 10 cards exist today, that we fully support.
  • Renzo: Thus, the Motorola titanium can support a 32 GB Micro SDHC C10
  • Brian: That's correct, Renzo.
  • Brian: Renzo, Motorola titanium can support up to 32 GB micro SDHC card class 10.

  Now I can be sure about memory that I want.

  I hope this help you too.

• Want to 750-114: migrate another computer with SSD

  Hi all

  Im trying to replace my old PC with this desire 750-114.  I have an SSD on my old PC and would like to just transfer the SSD to my envy again as the main drive.

  I couldn't find any driver motherboard online and I don't want to clone the hard disk on my new PC I want to keep all the files on my old intact SSD.

  is it possible to boot from my old SSD?

  Thank you!

  weidake

  Hello;
  
  Let me welcome you on the HP forums!
  
  I read your message want to migrate a SSD from one PC to another and wanted to help.

  Simply boot the second PC since a SSD at the first - No..  IF the PC had identical hardware, then maybe, but with a different material, the necessary drivers will be missing and the PC does not start.

  There is a way to actuall "migrate" from the old PC to the new one, using the same player - but it involves costs and considerable work.

  Macrium Reflect allows image and restore the PC and they have an option that you can do whatever you want - mainly migrate everything from your old PC to the new - it's called the redeployment, and it is not available in the free version.  You must buy the Home version.

  The way it works in your case is that you buy Mr., install on a PC and use the option to create the bootable rescue media.

  Then you put the old SSD in the new PC, insert the bootable rescue media and boot into MR.

  Once it is running (it may take a few minutes to load), follow the instructions in this thread (from step 3): http://www.macrium.com/help/v5/How_to/Redeploy/ReDeploy_a_system_to_new_hardware.htm

  Mr. then read drivers (from support that you provide) and replace the drivers on the SSD with the drivers for the new PC.

  NOTE: If you do not have the drivers for your new PC in one place, and then download and install DriverBackup - you can use this to backup all the drivers in a single folder.

  But it's only PART of the solution (I said that some work is involved!)

  The former DSS had active Windows using the license on the old PC - and OEM licenses are not transferable from one PC to another.

  If the new PC is preinstalled with Win8x or newer, you can retrieve the info from following these instructions (based on 90 days version) license:

  (1) for Windows 8 x: key product - find for Windows 8

  (2) for Windows 10: download the OEM of Windows - MajorGeeks product key tool

  You will then need to manually enter the product key found by the tool to activate Windows again on the new PC.
  
  Good luck

• COM Bluetooth port 90-100% CPU load

  I ' am running a PC application via a COM port normal, nothing complicated 38 kbaud. The CPU load is about 4%.
  Then I try to do without this thread, that oops the CPU rises to 96% of the load.

  I use a different computer manufacturers with Toshiba stack and module internal BT. Win XP SP2. Yes I have updated to the last stack of Toshiba.

  The same problem on my second computer (since it is a dual core I get 50% CPU) also with Toshiba stack.

  If use an external RS232 Bluetooth adapter everythings works fine at 4% of CPU load. I have however to connect a USB Bluetooth, same problem 96% CPU adapter.

  I'm doing something obviously wrong?

  / B

  Each laptop manufacturer typically feature test prior to the distribution of laptops. Have you tried to know what say the support from the manufacturer of this problem?

  I use for Toshiba laptop and BT works well and something like that doesn't happen to me.

• HP Pavilion g6: Pavilion goes directly into hibernation in Windows resume, and I can't go to the BIOS

  When I turn on the power, it goes directly to the recovery of Windows, and after it loads the user connection, it goes directly to the hibernation and it stops after a few seconds.  Since it is in Quickboot mode, it will not BIOS open with any method.

  How can I fix this, please?

  Apparently struck only the Windows key in the repetition while it's start, was the solution.

• MBP 2014 - possible photo of dvd?

  Hello

  I have MBP 2014. My second Mac since 2005. I have a Photo with mix of photos and videos and recorded as a project project. I am trying to burn on a DVD for any DVD player can watch it. Unfortunately, the file is in m4v format. Y at - he can play any build-in features that I can use to convert successfully or burn him if any DVD player? I was expecting something easy to just make a copy of DVD while all the photos and videos already in my MBP. There is no iDVD in my MBP to 2014 and I don't want to pay the third party for this software. I can't wait to go back to Windows for this task simple where I used to do in the past, but now I have all my animals in the MBP.

  Thanks in advance,

  NO.

  You need software such as iDVD or Toast or other
