• HP ProBook 6440 b: update Bluetooth module - is it possible?

  Hi all

  I have a HP Probook 6440 b 10 Windows running. It has a bluetooth module with the manufacturer 537921-001 which is Bluetooth 2.1. Is it possible to improve it with HP ProBook bluetooth module from the manufacturer of 6475 b 655792-001 which is Bluetooth 4.0? I looked at images of the module, the two and they look almost identical... It will work?

  Thanks in advance

  Good news, I bought the bluetooth module I mentioned above and it worked perfectly. The interface is the same, the Device Manager it recognized when I booted up the laptop and then install the driver... and all together. Thank you.

• ProBook 6440 b: cannot upgrade to Windows 10 - "The CPU is not supported" error message

  Hello everyone

  I have a HP ProBook 6440 b. CPU is intel core i7 M640. It is currently running Windows 7 64-bit edition. I'm trying to update to 10 Windows using Windows 10 Upgrade Wizard and it gives me error. It says "Windows 10 does not work on this PC. The CPU is not supported (NX). »

  Any help will be appreciated. Thanks in advance.

  Hello:

  I suggest that install you the upgrade from the DVD (authoring tool of your own from the link below - media Make).

  https://www.Microsoft.com/en-us/software-download/Windows10

  The DVD will bypass the hardware checks.

  Also, when you install W10 from the disk, skip verification of updates when you are prompted.

• ProBook 6440 b: Probook 6440 b memory block

  I recently bought a HP Probook 6440 b (refurb), only for the purpose of trying 10 windows.

  The first thing I did was replace the puny 160 GB HARD disk with a 1 TB HARD drive and buy 8 GB RAM to replace the cam laptop with 2 GB of RAM.

  After Installing Win 10 and the upgrade of memory, I noticed that my usable reported memory is 2998 8192 MB MB.

  Making a few arround to dig, I learned that it is because my laptop, while the solid case is below on the Department of BONE.

  Belarc shows 2.53 Core i5 M540 64-bit ready Multi-Core system (2 in total) and type hyperthreading (4 total)

  However, from what I found, the 32 bit OS, is to limit my memory to 4 GB total!

  So my quesition is as follows.  Is there a solution?

  I would get all of the 8 GB (or at least more than 2.93).  Is this possible without a major disassembly?  Also, from my research, I think that the reason that the usable memory is that only 2.93 GB is because I have an integrated graphics (GPU) which is aspire little memory.

  Don't know if I can come back 1/2 of a 2 stick memory package, so this may have been a lesson in "read-twice, once arrested.

  You are the very welcome.

  The steps you described are quite right — and Yes, all data will be lost, so I would not invest a lot of effort to do something else until you get the discs.

  If you order by regular mail, the load is about $10 for the scope of delivery.  I usually get them within a few days.

  I don't foresee any problems.

  There is a full set of W7 64 bit drivers on the support page, and there should be no difference in the W10 x 64 conversion.

  The only difference will be that Windows must be able to "see and use" almost the total amount of memory you have installed.

  There may be some memory reserved for the video card if your laptop is the Intel integrated graphics card.

  You will have to start from the W7 x 64 disk operating system in order to install W7 x 64.  It will run from the 32-bit Office.

• HP ProBook 6440 b: form of inconsistency between documentations of HP?

  Hi all

  I have a HP ProBook 6440 b and wanted to browse the HP site for the documentation of the specifications. I've found two documents on the model - one of them is a big picture and another a manual in pdf format. I realized that the specs of RAM on these two different documents.

  According

  http://h20564.www2.HP.com/hpsc/doc/public/display?docid=emr_na-c01987730

  HP ProBook 6440 b supports DDR3 SDRAM PC3-10600 (1333 MHz)

  considering that according to

  http://h20565.www2.HP.com/hpsc/doc/public/display?sp4ts.Oid=4095207&docLocale=en_US&docid=emr_na-C03...

  It supports configurations at 800 MHz DDR2 PC2-6400

  Why this discrepancy?

  Hello:

  It is a peer to peer forum.  HP maintains no official presence here.

  The info in the maintenance manual is incorrect.

  All models listed in the maintenance manual use memory DDR3 - PC3-8500 or PC3-10600 (which is backwards compatible with PC3-8500).

  If you want to bring this matter to the attention of HP, you can do so on the link below.

  https://SSL.WWW8.HP.com/us/en/contact-HP/connect-with-HP.html

  Peroxide of hydrogen used to have a link quickspecs for all of their professional laptops, but I can only find one for the 6440 b that has been transferred to a 3rd party website.

  This document will be very detailed information on the 6440 b and as you can see when you click on the pages, memory DDR3 is what they have.  See page 5.

• Upgrade RAM ProBook 6440 b

  Help!

  I'm trying to upgrade the RAM in my probook 6440 b

  It came with 2GB, and I want to bump it up to 8 GB.

  I already have very RAM, but can't access the slots of RAM (other than the one on the bottom of the unit).

  I believe that the slots are located under the keyboard, but I can't find the removal instructions (or better yet, a video)

  Normally trolling YouTube & Google is what I need, but I hit a wall.  Even the videos that I found who claims to be the correct model are not.  In some cases that aren't even from the same manufacturer and no part in the layout of my laptop.

• Cannot collect dhcp information using device-sensor for profiling.

  Hello

  I try authentication dot1x/MAB (there is no issue here), but I want to collect information dhcp devices requesting the IP address of the dhcp server to the profiling using the sensor in the camera (cdp collects on - no problem) but when I check for all device-sensor of the show # dhcp cache, there is no single entry for dhcp data.

  The dhcp server is on the switch where these devices attempt to access the network since then and this should be the case. However, I noticed the following I don't know if it is bound (from device-sensor #debug error)-same error appear with different X value.

  I am more concerned about collection attributes now rather than send... !

  A couple more questions:

  1. do you have active monitoring dhcp ?

• Envy 15 t-j100 Select Edition: the device is not connected to the computer. Please insert the authentication device.

  Hello

  So I'm working on a LT desire that has been upgraded from Windows 8.1 to 10 recently and it is this message on the login screen "the device is not connected to the computer. Insert the authentication device. We can't identify what it means or what needs to be done to clear the screen. The user States that the fingerprints of impression of BIO sensor doesn't seem to work either. I looked in the Device Manager, and I see a Synaptics PS sensors (WBF) listed here and is properly installed. I even updated the driver of sensor ep on the support site of the desire, and we still see on the login screen.

  Y at - it no information or help to clear this message?

  We also note that the number on the keypad lock seems to be disabled during startup of windows 10 upwards. Before on windows 8.1 has been activated. Is there any setting to 10 to keep the active number lock.

  The user says if 10 can be made to work well, then we can go back to 7 or 8.

  Please notify.

  Thank you for your time.

  Seems to have been resolved in re - install the software HP Simple pass then go and reconfigure the settings. Message no longer appears on 10. User LT installed with 7 however. Best decision.

• A sensor of fingerprint Satellite U400-151?

  I bought a Toshiba Satellite U400 T5800.

  When I read the book it says there FINGER recognition but when I open it I don t see it anywhere.
  Satellite U400-151 finger touch so I can open a windows session?
  Thank you

  N ° Satellite U400-151 doesn t have fingerprint sensor. If you control s operating manuals, you will see that the fingerprint sensor is optional and not available on each Satellite U400.
  Maybe Satellite Pro's fingerprint sensor. For this model of laptop, there are several different hardware platforms available.

  Anyway I like this small Satellite and I hope you will enjoy it a lot. ;)

• Sensor of fingerprint and Portege R200 prints. How does it work?

  Hello forum,.

  I bought a Portege R200 in 2006. Works fine for me, but I could never try the sensor of fingerprint fingerprints-because I couldn't start at the same time and I didn't have enough time to find the problem ;(

  Could someone tell me here, what I have to do, to use it?

  I tried on:

  1. I click the omnipass key symbol in the systray and select 'add a new user '.
  2. I completed the form folling "windows account information.
  3. I selected "authentic prints digital driver."

  -> Error: selected item cannot be found

  I have no idea. What is the problem and how can I solve this problem?

  Best regards
  Martin

  Hello

  I have laptop with fingerprint sensor, but I checked the document of the user s manual for Portege R200. Please see page 62-64. There are good explanation how to use it.

• Sensor of fingerprint identification does not work and the touch screen unresponsive

  iPhone 5 s 32 GB Stopped working sensor of fingerprint identity with the touch screen not responding

  latest version of iOS

  Flickering of screen there are some horizontal lines appear on the screen for a while in very minor rainbow color

  went to the apple support no help in troubleshooting. They asked me to request a replacement pay for 22K INR.

  I think that it is not worth getting a replacement of the delivered phone to new/old version as new series is available in the market, paying a large amount.

  I would like to hear your valuable contributions.

• Envy 15 computer laptop k000nx - we haven't found devices wireless on this pc

  Hi all

  I have a problem with my devices wireless on my Hp envy 15 computer laptop k000nx - 8.1 Windows

  I tryied many ways to activate the network wireless by reinstalling the drivers from the hp site and disable airplane mode.

  even when I use the Troubleshoot utility he sees only the cable problem.

  but there is no sign of my wireless or bluetooth, they're just gone.

  and here are some pictures for my problem...

  

  Hello:

  I agree that devices are not present and do not need drivers.

  I recommend that you contact HP technical support and file a case under the guarantee pension.

  The wireless and bluetooth are on the same removable wireless card and her card is defective or not properly seated.

  I would have recommended you remove and reinsert the card, but the service manual for your model indicates that this procedure is possible only by an authorized service center.

  I can see why you have to disassemble basically the whole notebook just to get on the wireless card.
