• Maximum RAM for notebook DV7-4000 series?

  I have a laptop ' HP Pavilion dv7-4000 Select Edition Entertainment Notebook PC ' 4 years ago (2010), model WA357AV.  Win 7 Home Premium 64-bit with Intel core i5 M450 @ 2.4 GHz and 6 GB of Ram.

  What is the maximum size of RAM so I wanted to update?  I can go up to 16 GB with 2 8 GB cards? It is important that the current memory cards are "unbalanced" because I have a 4 GB card and a 2GB card when I always read both should be the same for the 'best performance '.  If "unbalanced" is OK, I might consider replacing just the 2 GB card with 8 GB, send me some 8 + 4 = 12 GB which would be obviously cheaper.

  Thanks in advance for any advice.

  Hello:

  Max ram with the processor of your model is 8 GB (2 x 4 GB).

  It's well run 4 GB + 2 GB but the memory does not work in DDR mode achieve higher.

  Replace the 2 GB chip with a 4 GB chip.

  That's the best you can do.

• HDMI + VGA issue / / HP DV7-4000 series.

  Dear friends,

  I have a question about usig external monitor with my HP DV7.  The model # is DV7 - 4287cl

  I have a HDMI port and a VGA port on this model. I intend to use an external monitor with it, but I wonder if it is not possible to use two external monitors with it since I have two separate ports?

  It's maybe a stupid question but I have a specific need to use an external monitor with my laptop, and have two rather than one would not be a bad option.

  Thank you, in advance.

  You can use an external monitor. The hdmi port will provide a much clearer sharper picture, but it's or the vga port will be acceptable. Two outputs is the limit of the video card, and one of those is always built in the computer screen.

• Pavilion dv7-4000 1 replacement of hard drives with more

  I have a dv7-4000 series double portable hard drive running windows 7 64 bit. One of the drives died and I am looking to buy a replacement and want to upgrade, but I'm not sure if I have 2 hard disks of different sizes.

  (1) can I replace factory bad HARD drive with a larger 320? (I'd then 1 factory 320 GB drive and 1 car again, more)

  (2) is the brand of the material of hard drive (Toshiba courses)?

  (3) are there any specific specs I should look for or avoid (ie. rpm, Gbps, etc.)?

  Hi wweksjk! : Yes, you can have 2 HD with different capacities for example on my PC of Xion MSI, which was built in 2006, I had 2 HD Western Digital, respectively 160 GB & 250 GB divided into 3 partitions

  the brand name is not as important as the number of turns faster the car turns your computer will be faster

  also look at the size of the buffer on the disk as well because the more it will speed up the boot time as well

  However install a new drive as boot drive will be complex, but if you follow the instructions that come with the HD installer it is possible

  for example, a 7200 RPM drive is faster than a 5400 RPM, but not as fast as a model k 10 or 15 k

  Good luck

  hope this helps to & help

  Happy holidays!

• New HP Pavilion DM1 4000 series max memory card

  Hello

  I am looking to buy a new ultraportable laptop and like the look of the new series DM1-4000. However, it seems that there are two versions available in the United Kingdom - the 4004SA DM1 and DM1-4027SA. The data sheet pdf, the noticeable difference only seems to be the maximum amount of memory installed (4 GB in the 4004, 6 GB in the 4027). I don't understand not why HP would impose this limit as both have 2 user accessible so-DIMM slots - my preference would be to upgrade the memory 8 GB by replacing both of the 2 GB so - DIMMS with 4 GB (after installing W7 64-bit rather than the stock windows W7 32 bit, it comes with).

  My question is this - is correct these limits of 4 GB or 6 GB or is it just a marketing thing?

  Interesting, the Maintenance and Service Guide (PDF) DM1-4000 series indicates the memory installable max is 8 GB.

  Thanks in advance. Any ideas much appreciated.

  Edit: Also noted there is a model 4020SA and 4020EA... both specify also 4 GB memory Max.

  There is not much sense, it?

  The maintenance manual makes it clear that portable computers running AMD processor have 2 slots of memory each hold 4 GB of memory.  See Chapter 1, page 2.

  Now, the Intel PC base seems to indicate that they cannot contain only 4 GB maximum memory - affordable housing from a single client.

• LaserJet 4000 TN: The printer HP Laserjet 4000 Series PCL5: error state & quot; message & quot;

  I sent the following message to Microsoft after a ' update:

  I have a printer HP Laserjet 4000 Series PCL5 TN which worked beautifully "black only" for many years. A recent update (Windows 10:12 / 22/15) seemed to put the printer in the "printer error state", when you try to print a simple document. It has been my default printer for a long time. I followed the suggestions of printer "windows 10", that is, unplug and plug - check cable (not USB) connections, remove the printer from the list of print devices /, reinstall drivers HP for Windows 10 (following suggestions from HP on HP site) - nothing seems to work. It has a network cable connection, but it is directly connected to my computer, no other computers are connected. See screen capture below. I even did a "recovery" of before 12/22! Any suggestions? Thank you. GM

  I received instructions from Microsoft:

  You run the printer Troubleshooter and identify the cause?

  If this isn't the case, we will do that by visiting the link below and see if it helps.

  http://Windows.Microsoft.com/en-us/Windows-10/fix-printer-problems

  Check also the update (KB number) has recently been installed on your computer.

  You can also restore printer drivers and check.

  To restore the driver, you can follow the steps below:

  • Press Windows + R on the desktop screen.
  • Type devmgmt.msc and press ENTER.
  • Expand the printer drivers and do a right-click on the driver and select Properties.
  • Go to the driver tab and click driver RollBack.

  Can I assume that you use a parallel cable to connect the printer to the computer.  If you do this is a known problem that can be solved.  Go to Device Manager and then click ports.  Double-click the lpt for the printer port, and then click on device settings at the top.  Change the default setting of the middle box checked in the box below to use any available interruption. I would also check the legacy down.  If necessary, turn the computer off and then turn it back on, but most of the time this solves the problem without a reboot.

• HP dm1 4000 series keyboards

  Hi, I bought the HP dm1-4310nr U.S. netbook and are having a problem.

  As you know WE use different keyboard configuration that we have here in Europe.

  I was hoping to replace my pc keyboard by purchasing the Northern version of ebay.

  Only flaw is that it is not any version of this keyboard model says in the market if.

  Some other 4000-series keyboard is compatible with it?

  Hello

  There are many keyboards for dm1 machines, they are the same SIZE with yours, but as mentioned on my first answer: you have bought a very special, not available on other markets so same size but may not work. For the keyboard from another supplier, sorry I don't know.

  Good luck.

• Switchable graphics option Bios Update Dv7 4100 series for hd 5650 m driver

  Y at - it another version of bios for my laptop? (I've included a few specifications of my laptop at the end of my post)

  I heard an update of the bios of other series that could control your switchable graphics. But my notbook integrates the latest version of the bios that I can download (v3.5, I think).  And this version does not include the switchable chart control.

  Why I ask this question? Because with switchable graphics disabled, you should be able to update your video card driver. With this driver I could play new games like far cry 3 or other new games with the quality, I should be able to play.

  My laptop:

  -Pavilion dv7-4177-eb

  -Video card: Mobility radeon hd 5650 graphics card

  -CPU: i5 M460

  -Motherboard: Hewlett-Packard 144 b

  with greetings

  Jori

  If you try to update the driver from AMD, AMD, be sure to do so only with the card on and not off AMD. If turned off switchable graphics, AMD map will not be displayed and the Intel card having for result the error you received.

  On a side note, AMD recommends sticking with the drivers from the manufacturer of the laptop.

• Help, please! Intel graphics hd 4000/nvidia k2000m questions

  Hey guys, I'll have two both of my graphics (intel HD 4000 + nvidia k2000m) first of all I am a musician and I run a recording software (avid protools) off the w530. for some reason, I'm having problems using a secondary monitor... The computer is not output any signal through the vga port or mini HD on the graphics card intel HD 4000... I tried to hit win + p to activate the option of mutiple monitor, I updated the driver of 4000 intel HD and still no signal output... so when I switch to the k2000m, everything works perfectly... both vga and mini HD port works, but for some strange reason, I get cpu overload in my burning software... Almost if the computer longer hard using the k2000m... Idk if this is a driver issue, but I really need the dual monitor working in my w530 function... Any ideas or suggestions to solve these two problems. Thank you

  Hi Mpcsauce,

  Welcome to the forums. All external monitors are dictated by the discreet displayport graphics card from Nvidia, such as the VGA and mini ports are physically connected to this card. Therefore, integrated graphics card Intel can only go out to screen integrated notebook (Nvidia card can do, if force you it in the BIOS).

  The best thing to do is to make sure that the graphic card in the BIOS settings is set to "NVIDIA Optimus", given that the laptop switches between card Intel and Nvidia, providing the best combination of performance and battery life. Your second question is strange, but I would like to begin by updating the drivers on the K2000m.

• Series Packet Question: How to calculate CRC

  Hi all, I have tryied to find an answer on how to calculate the CRC on a RS232 packet received, its really driving me crazy!

  im a beginner, learned how to use labview read on different forums, and I had managed to build really good applications, but im stuck in this, hope someone can help me...

  OK, so im constantly receive packets of 15 bytes:

  A5 09 0C 00 61 05 1F A0 10 00 05 00 04 05 3F

  A5 09 0C 00 61 05 10 00 05 0C 2F 03 A0 1F-3F

  A5 09 0C 00 61 05 10 09 05 09 04 09 A0 1F-3F

  the supplier for material gave me the following code to calculate the CRC:

  Control CRC program:

  #define unsigned char uchar
  UCHAR CRC_Bitwise8 (uchar * buf, uchar size)
  {
  UCHAR i, j, b;
  UCHAR crc = 0;
  for (j = 0; j<>
  {
  b = * buf ++;
  for (i = 0; i<>
  {
  If (((CRC^b) & 0x01)! = 0)
  CRC ^ = 0x18;
  CRC > = 1;
  b >> = 1 ;
  }
  }
  return crc;
  }

  so my question is, how can we insert this code in labview? any example?

  Thanks in advance, this forum has really helped me learn labview in a practical way.

  You can use my code for the thread that I've referenced.  To play with a web version of my code go here. My code is based on the code on this Web site.

  My code to the following parameters:

  Calculation of the CRC: Other (specify)

  Order of the CRC: 8

  Polynomial CRC: 0 x 30

  CRC initial value: 0

  CRC XOR final value: 0

  Reflect the preprocessing of data: TRUE

  Match the data before Final XOR: TRUE

  In your messages, the A5 09 0c is certainly a header.  I think that the 00 following is also part of the header, but without the manual, I can't confirm.  00 will not affect the calculation of the CRC, in order to get the same results with it and without it.  So, in your first example, I use 61 05 3F 1E A0 00 05 00 04 10 and the result is 0x05.

• A transmitter/receiver for mouse 4000 series will work with my mouse of series 5000 and 3000 series keyboard?

  The transmitter/receiver for my wireless 5000 mouse is dead!

  If I buy a 4000 wireless mouse 3000 (from office all 5000) wireless keyboard will work on the ARVA 4000? I think I got that right!

  You guessed it right, and it depends on the brand and model.  If they specify a "unifying" receiver it will work, otherwise contact the MFR.

• 9000 series - __doPostBack questions

  I am creating hyper dynamic links in an asp.net ListView in a web application I'm developing for use on Black Berry (and several other mobile devices).

  I tried to use the controls of the asp: LinkButton, but they do not seem to answer in the Black Berry (using the simulator that is downloaded from the website of Black Berry - 9000 series).  I actually activate JavaScript, another script that I use for purposes of style does not seem to work.

  My other option was just to handle the onclick event client for a span element, which I style to look like a hyperlink, then call the __doPostBack in the script to trigger the code on the server side.  Nothing seemed to happen when I did it, so I joined visual studio 2008 to debug.  He called the script, once he hit the __doPostBack call hung for a bit & then the Black Berry Simulator crashed.  I have a dump bug, if necessary.

  I try to understand what I can do, we want to avoid transmitting the ID via the query string.

  Thank you
  Sean McGill

  EDIT: Remove personal information

  Most of the __doPostBack issues can be resolved with this:
