No Bluetooth hardware in $850 E3S21UA#ABA ?

Looked all over the place in this E3S21UA#ABA Envy 15' Win 8.1 Laptop and can not find any Bluetooth hardware. Looked in Device Manager>Network Adapters and all I see is Realtek Family Controller and WiFi adapter.
This question was solved.

Hi:
You are correct.
The specs for the HP ENVY 15-j006cl Notebook PC indicate wireless only.
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c03942496&tmp_task=prodinfoCategory&cc=us&dlc=en...
If you use bluetooth, you should be able to easily swap out the existing wlan card with one that also has bluetooth, listed in chapter 3 on pages 25-26 of the service manual.
http://h10032.www1.hp.com/ctg/Manual/c03733656.pdf
I would not get the Mediatek model.  Lots of connectivity problems.
Give the choices listed, if it were me, I would opt for the Intel 2230.
Specs on the card.
http://www.intel.com/content/www/us/en/wireless-products/centrino-wireless-n-2230.html
None of the cards listed are dual band (2.4/5.0 GHz) cards.
You can get one on ebay for cheap.

  • Mac Mini Bluetooth hardware problems ?

    I own a Mac Mini Intel Core 2 Duo 1Gb bought last October, an Apple wireless keyboard and an Apple wireless mouse, both I formerly use without any problems with my old Powerbook G4. By now, I used them with my Mac Mini it worked perfectly fine. But since two or three weeks, I’ve got big Bluetooth connection problem. Randomly, after one or two hours of use, both keyboard and mouse loose connection and the Bluetooth symbol change itself into a strange one. I had a look on your site to learn the meaning of it and the symbol is see which is a Bluetooth symbol with a horizontal zebra means that no Bluetooth hardware can be found! Does my Mac Mini built-in Bluetooth card have problems?
    Since I haven’t got any wired USB keyboard or mouse I have to reboot my Mac Mini quite roughly. Sometimes one reboot is enough to make the Bluetooth of Mac Mini to work again, sometimes not and I have to wait a little bit more (more than ten minutes). I can see it works again as the Bluetooth symbol is the right one again (the one with the dots).
    It is very annoying. And I am a bit sad to have such problems with Apple stuff. Is there something I could do to avoid such a waste of time? Or shall I call Apple Care for fear it should be a hardware problem.
    Of course, I use brand new batteries for both of them.

    My mini is doing it as well. Just started doing 2-3 weeks ago. Logitech Denovo or Apple Bluetooth. Doesn't matter which. Loses it in about an hour or so. Al Keyboards and mice were purchased at about the same time as the core 2 duo mini, ~ last October.
    Must power cycle the machine to get it back and it must be paired again. Very annoying. Can't remember if it coincides with an Apple update.
    This mini has had the superdrive replaced twice, once within 6 weeks of purchase. Ever since Leopard, it's been close to the best media head. now this...
    Sigh.
    (What makes it not the best? Frontrow doesn't sort titles correctly [1, 10, 2, 3 - wrong!], doesn't force mount aliases in the movies directory, doesn't put out 1080p without hacking. And I'd so love eyeTV integration with Frontrow. It'd be perfect then.)

  • [Solved] bluetooth hardware switch - Thinkpad T400

    Hello,
    I've got a Thinkpad T400 with integrated bluetooth, but I don't really use bluetooth, so I want to disable it to save battery power.
    I figured out, how to disable it via laptop-mode-tools on startup, but when I use the hardware switch for Wlan and bluetooth to turn my Wlan on and off again bluetooth starts up again.
    I also figured out that I can disable bluetooth via "echo 0 > /sys/devices/platform/thinkpad_acpi/bluetooth_enable".
    I want to put that command in a script, that is only executed, when the bluetooth hardware is detected.
    Now I'm wondering if any of you guys knows some script, like that.
    I've already had a look at the udev files, but I couldn't figure out which one will do the job.
    Maybe it's the wrong way and there is a lot easier solution.
    Thanks in advance, any help would be appreciated,
    David

    I do this for disabling Bluetooth on my X220 ThinkPad using Fn + F9.
    I created the file /etc/acpi/actions/bluetooth.sh
    #!/bin/bash
    BT_RFKILL=$(rfkill list | grep tpacpi_bluetooth_sw | sed 's/\([0-9]\+\):.*/\1/')
    BT_STATE=$(/usr/sbin/rfkill list $BT_RFKILL | grep "Soft blocked: yes")
    if [ "x" == "x$BT_STATE" ]; then
    /usr/sbin/rfkill block $BT_RFKILL
    else
    /usr/sbin/rfkill unblock $BT_RFKILL
    fi
    exit 0
    And the file /etc/acpi/events/bluetoothconf
    event=button/f24.*
    action=/etc/acpi/actions/bluetooth.sh
    Restart acpid.
    # systemctl restart acpid.service
    Now I press Fn + F9 to toggle bluetooth off and on.
    Rfkill needs to be installed for this to work.

    I have Mac Pro 2007, which have no bluetooth hardware. What should I do to use Apple wireless keyboard and magic mouse??? Can 'third party's internal bluetooth card' be used for this purpose? Help me please...

    You can find the Apple Bluetooth card on eBay for as little ten dollars (says its for the 2008 model Mac Pro, not sure about the 2007).
    http://www.ebay.com/itm/Bluetooth-Board-iMac-and-Mac-Pro-922-8233-922-8233-/1208 49278570
    Here is a link to a full explanation of the card and how to install it. Part numbers may differ a bit as that is an old article and newer models have come out.
    http://www.xlr8yourmac.com/systems/Mac_Pro/Bluetooth_MacPro_install/Bluetooth_Ma cPro_install.html
    Just make sure that the part will work in your model Mac Pro. To that end, you may be better off avoiding eBay and going to a parts reseller. There are even third party cards that use the internal Apple bluetooth slot.
    http://fastmac.com/bluetooth.php
    In theory, using a USB or PCI card will work at login so long as it is recognized by Apples drivers. You say you need to launch an application to use your current USB Bluetooth dongle? If it is not controlled by the Bluetooth icon in the menu bar then it must be using a third party driver of some sort. Unfortunately, I don't know off hand which USB and PCI cards are supported.

  • Requirement for bluetooth hardware

    Perhaps something very simple is eluding me, but WHY do some files/"applications" require bluetooth hardware to be opened? I don't see any relationship between some of these and wireless connectivity.

  • Bluetooth Hardware for my notebook DV6

    I have a Pavilion Notebook DV6 PC. 
    Problem 1: From Day 1 the audio of this notebook is absolutely pathetic. Unless you have a headphone or speakers, one cannot hear anything. 
    Is there anyway to get the audio systems enhanced? 
    Problem 2: I purchased a blue tooth enabled wireless speakers. My laptop does not have the blue tooth feature. Steps I took now to get it up and running: a) Install Broadcom Blue tooth drivers. Issue: Bluetooth still does not come up in the list of wireless adapaters. b) Intel WIFI technology is disabled. Issue: Does not enable. Not sure what to do? Do I need to enable it so my bluetooth will be installed properly. c) Where can i find Bluetooth hardware to install it on my laptop Issue: i cannot find it in the HP site. d) Does the Bluetooth hardwares come with the softare drivers too? 
    Problem 3: Is this the right forum to state my problems? 
    Any help would be aprpeciated,

    Hi People
    I am running Mac OS X 10.6.8 on my mid 2010 Macbook Pro 2.4 Ghz. I cant find my bluetooth hardware. Can anybody please tell me a procedure to fix it. It been a long time that I have been having this problem and even the apple guys are unable to fix this problem.
    Please help :|

    SMC reset.
    PRAM reset.
    And if those don't work you can try a bluetooth factory reset.

  • Wifi and Bluetooth Hardware not getting detected

    Hi, I need help from HP. Wifi and Bluetooth hardware on my laptop are not getting detected. I have installed the drivers properly but the hardware  itself is not detected when I start the notebook. The wifi had problems initially but then it worked fine for sometime and now it is not detected at all. Same is the problem with bluetooth also. The hardware is not visible in the device manager itself. Please let me know the possible problems and also help me with the solution. Thank You. Model - HP Compaq 15s001-tuOS - Windows 7 64 bit.

    Since the wifi and bluetooth functions come from the same mini-pcie card it seems likely it has failed.  This is the Service Manual: Your Manual See p. 61. Unfortunately getting to the module requires extensive disassembly, but short of removing the motherboard.  The wireless module itself will be very inexpensive. But you may need to pay somebody to install it.  If this is "the Answer" please click "Accept as Solution" to help others find it.

    Please read this whole message before doing anything.
    I've tested these instructions only with the Safari web browser. If you use another browser, they may not work as described.
    This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac. 
    These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing. 
    Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects. 
    Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands. 
    Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply. 
    Launch the Terminal application in any of the following ways: 
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.) 
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens. 
    ☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid. 
    When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign. 
    Step 1 
    Triple-click the line of text below on this page to select it:
    kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -ef 
    Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open with the output of the command. If the command produced no output, the window will be empty. Post the contents of the TextEdit window (not the Terminal window), if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
    Step 2 
    Repeat with this line:
    { sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix\.cron)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; echo; sudo defaults read com.apple.loginwindow LoginHook; echo; sudo crontab -l; } 2> /dev/null | open -ef 
    This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator. 
    Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step. 
    Step 3
    { launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}'; echo; crontab -l 2> /dev/null; } | open -ef 
    Step 4
    ls -A /e*/{cr,la,mach}* {,/}Lib*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts .la* 2> /dev/null | open -ef  
    Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting. 
    Step 5
    osascript -e 'tell application "System Events" to get name of login items' | open -ef 
    Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output. 
    You can then quit Terminal.

  • Really Weird One: Install Ubuntu on Partition, Bluetooth Hardware Disappear

    So ... I cloned my Mac OS X install onto an external drive, repartitioned my hard drive, cloned my install back onto my hard drive, and installed Ubuntu on the new, smaller partition.
    But now, on the Mac OS X install side, as far as Mac OS X is concerned, Bluetooth doesn't exist -- it's as if this system doesn't have Bluetooth hardware.
    I haven't even the faintest idea where to start. Any ideas?

    I have the same problem (I have an nforce3 board) where sometimes both eth0 and eth1 won't work, and the only way to fix it is to shutdown and start over (oh, and I don't think it's an Arch64 problem, since it happened to me in Arch32 as well).  It doesn't happen often enough to bother me though, so I haven't really looked into it.  As for problem where eth0 and eth1 switch, maybe this will help (so far it is working for me).
    From  /etc/udev/readme-udev-arch.txt:
    - The "proper" way to configure net interfaces to hold static names within udev rules.  Add lines like these to a custom rules file such as
      /etc/udev/rules.d/01-network.rules:
        SUBSYSTEM=="net", SYSFS{address}=="aa:bb:cc:dd:ee:ff", NAME="lan0"
        SUBSYSTEM=="net", SYSFS{address}=="ff:ee:dd:cc:bb:aa", NAME="wlan0"
    - To get the right mac address use this command:
        udevinfo -a -p /sys/class/net/<yourdevice>
    - Make sure you use lower-case hex values in your udev rules.
    - NAME= determines the name of your network card.  Use these names in your
      network configuration in rc.conf as well.

  • Bluetooth hardware hdx 16t 1200

    I can't find bluetooth in my device manager. I recently couldn't find my biometrics fingerprint scanner either but found a solution on the forums and it appeared. Is there a way to download the hardware or is there a fix. I wiped my computer and fresh installed windows 7 ultimate twice. I just cant find a way to restore the bluetooth hardware on the device manager. Any help would be awesome. 

    Hello chsher01,
    I understand you are having issues with your Bluetooth not showing up in your Device Manager. If you could post which wireless devices is installed in your computer I can attempt to find you the correct driver. The fact that this is a CTO unit means that the installed hardware may be different from the standard unit.
    Please re-post with either a screen shot of your Device Manager showing your Wireless device or indicating the name of the device in your post. Thank you posting this issue on the HP Forums. Have a great day!
