Spectre x2 13 WWAN

We have som users experiencing problems when using mobile broadband.
They shut off the PC by pressing the power button, so Windows does not shut down fully, but goes into standby/hibernate.
When they power on the computer again, the WWAN connection says limited or no connectivity, and they don't get a connection and internet access until they restart Windows.
They also experience poor connection on WWAN after using the computer for some time, which sometimes ends up with a limited or no connectivity message.
OS is Windows 8.1 Pro, original HP image.
The WWAN module is HP lt4112 Gobi 4G Module
Drivers are the latest from october 2013

I have experienced the same problem: After waking up from standby the coputer is not able to access the internet via the Gobi 4G Module. The connection is always restricted; so no internet connectivity. I didn't realize the connection getting poor after some time, at least so far.Is there any possiblity to regain internet access after waking the computer from standby without restarting? That would be a huge help!My system now is Windows 10 Pro (x64) but I already had the problem with Win 8.1.

After upgrading to windows 8, spectre 14 usb3 slow

are there any usb3 fast drivers for spectre 14 after upgrading to windows 8, the drivers of windows 7 there are not compatible with windows 8

Hello rumbacha. I understand you're trying to locate some drivers for your SPECTRE for Windows 8.
There are quite a few versions of the SPECTRE so I will need your product number to identify exactly which model you have. This document can show you where the product number is located.
Once I have this I will attempt to locate the drivers for you.
Have an excellent day!

Spectre ultrabook speaker

HP Sectre Ultrabook / Windows 8.1/ Can not seperate controls for ultrabook speakers from headphone jack. When I plug in headphones to the 3.5mm jack on the side there is an acknowledgment that headphones are plugged in and sound does come through, but the level controls remain with the pc speakers. When I look at ultrabook speaker proprieties it lists them as being attached to the 3.5mm jack. See picture below. Here is an image of playback screen with headphones plugged in as well. This is a problem for me because the laptop audio settings are already really loud out of the headphone jack. I had the ultrabook set at 65% volume and plugged the headphones in and started playing some music. I thought I had blown my headphone speakers and would have blood coming out of my ears it was so shreekingly loud. I am already hard of hearing but I can only have the volume at 30% on this ultrabook before it starts getting too loud out of the headphones. I thought that maybe it had something to do with the Beatsaudio settings but they are tied together it seems.

Crackling sound while playing music in HP SPECTRE 15-4010nr Ultrabook

Hi all,
I have recently bought [4th Jan. 2013 ] HP SPECTRE 15-4010nr Touchsmart ultrabook with beats audio.
I am very unhappy with sudden/random crackling bursts of noise while playing music.
The problem is not restricted to hp inbuilt speakers as it also reaches on headphones, so it's something internal to laptop.
Its really disappointing to have such a bugging issue from this high end laptop.
Please let me know if there is a solution to this problem.
Thanks in advance!!

Yeah even for me it seems unhooking power adapter does the trick !
Even my Laptop is just 4 weeks, how could manufacturers let so common bug seep through their high end laptops.
Are these not tested for audio video quality ?
Anyways I need an alternate fix as I do not want to lose my laptop for a month, in exchange or return process.
P.S.: Sound drivers re-installation is of no use.
HP Guys, thanx for ur concern, but if u can give a fix for AC adapter noise interfernece it will be great. !!

HELP! HP Envy Spectre XT Ultrabook with NO sound!

I currently have no sound on my HP Spectre XT Ultrabook PC!!! Upon buying the laptop it had Beats audio on the laptop. That stopped working recently, but I still had the normal reduced audio, until that stopped completely soon after. I have tried multiple things to fix this problem, all without success; I tried troubleshooting the problem, I tried updating the audio driver (it said I already had the most current version), I tried uninstalling and reinstalling the driver, I tried updating the BIOS on my computer and NONE of these have worked; I still have no sound! Please help to fix this problem!

Since today is HP expert support day, if there is an expert out there, PLEASE help fix this problem!!!!!!!!

Audio problem; buzzing noise (HP Spectre XT TouchSmart 15-4011nr)

Hi, I recently bought an HP Spectre XT TouchSmart 15-4011nr Ultrabook. I'm getting this annoying buzzing noise while listening to music or streaming movies. The store change my laptop for another one and after a few minutes listening I got the same behaviour on the new (same model) laptop. Is this a model problem? Is there anyone with the same problem?

Solution found for me. First, a little background. I have a HP Spectre XT Touchsmart 15-4010NR and also have the same annoying buzzing noise. Usually lasts less than a second and is intermittent. Counted it 13 times in four minutes of a YouTube audio file. Time between the buzzes varies significantly ranging from a second or two to over a minute. Once during the four minutes the audio cut out completely for less than a second. My solution, I unplugged the AC adapter. No more problem whatsoever as long as I'm on the battery. Tried this multiple times, plugging the AC back in for a few minutes, then the same on battery. The result, the buzzing occurs only when the AC is plugged in, and does not occur at all when on battery power. The AC power adapter provides power and charges the battery normally. Not sure what to conclude from this. I suppose the AC power adapter or cord could have an issue. Not going to go out and buy another one to test whether this is the case. It's an inconvenience, but I'll just unplug the AC power when listening to audio. If I listened to long recordings or movies this could become a real issue. I'd be curious to know if it's a hardware problem, or something I could adjust in the settings on the computer, or something else like a grounding issue. Interested if others can confirm my findings and expand on them. out

USB Serial CDMA Mobile WWAN CCL PPP PL2303

Hello all,
I have an internet connection issue or issues. It seems this is a complicated issue because there are so many layers involved.
Hardware:
iMac9,1
2, IOGear USB Extension cables (powered)
Mobile phone manufacturer supplied USB-Serial Cable.
Huawei branded CDMA 2000 1x RTT mobile phone with Qualcomm modem and Prolific PL2303 USB-Serial Bridge.
R-UIM card for local ISP in Nepal (United Telecom Limited)
Software:
Mac OS 10.6.8
I have tried a few different ways to make the connection and getting a connection isn't necessarily the issue.
First I tried to use the Prolific PL2303 kext. It's widely known you have to add the devices Vendor ID and Product ID to the info.plist file for the driver to load the device at boot time. But, apparently we don't need that third-party kext because Apple has built in support for Huawei as evidenced in three existing kext files: WWANSupport, WWANSupport1, and AppleUSBMergeNub (that lives as a plugin inside IOUSBFamily.kext). Problem was that the phone was not being recognized by the system even though the Vendor ID was a match. Any guesses why?
I figured a way for the device to be recognized via the CellPhoneHelper.kext. Huawei is not listed but duplicating the 'Qualcomm CDMA Technologies MSM (KPC680)' IOKitPersonality and then reconfiguring it to match my Huawei device by changing the Vendor and Product IDs worked perfectly. Once I cleared the system cache files and rebooted the phone was recognized immediately as a WWAN device and I could set it up in Network Preferences. Using the Generic and CDMA settings for the modem script I am able to connect. That's where the fun bit ends.
The connection gets wonky. It randomly leaves me in limbo, seemingly connected but not able to receive any data. If I 'disconnect' using the WWAN menu, it shows me as being disconnected but actually I am not, the phone is still be connected to the tower. If I open up a serial program I can see that the phone is still sending data. The only way for me to end the connection is to unplug the USB cable. Then I can 'Connect' again and everything pretty much repeats. I will have a decent connection and then at some random point I will loose it and be unable to disconnect from the tower. This is a stationary setup; not roaming.
One thing I have noticed is that the tower will give me a different WAN address randomly. Maybe this is the issue! While connected I will see in 'ppp log' that I am being logged out and logged in again and then I am given a different LAN address and WAN address. Sometimes I will get an error, 'Could Not Authenticate" and I will be disconnected. Sometimes it appears to work seamlessly. This all happens automatically. I am not sure from which side this is being initiated, my modem or software or the ISP's?
I have poked around but don't really know what I am looking for. Is this an issue with the CDMA.ccl, or an issue with PPP, or is it a USB IOKit issue, or a kext issue? Who knows.
When typing 'sudo dmesg' in Terminal I get something that seems odd to me, but might be completely normal.
AppleWWANSupport1: Version number - 2.0, Input buffers 16, Output buffers 4
AppleWWANSupport1: Version number - 2.0, Input buffers 4, Output buffers 2
I took note of the Input and Output buffers in the CellPhoneHelper.kext info.plist and they are 16 and 4 for my device. I don't know why 4 and 2 immediately override those. I don't see anything in AppleWWANSupport1 that has 4 and 2 set for buffers. Could this be the issue, i.e. the connection freezing because the buffers get full? Or could it be because the mobile phone is using two channels for the modem, /dev/cu.wwan and /dev/cu.wwanCNTL and that is normal??
I took a look at the CDMA.ccl modem script. I am not a modem script designer but I noticed that 'C' is set twice in the same init, &C1&C2. I am not exactly sure why that would be, any ideas?? Track remote DCD (&C1); Unix compatible DCD control (&C2). What about 'hsreset'? Not sure but I guess the Prolific PL2303 chip handles the serial port flow control options? The literature is a bit out of date on this.
So, lots of questions and no answer so far. A bit too complicated as there are so many layers working together and this is not a supported configuration. I do see a lot of people asking similar questions but mostly it's on different systems, like Linux, etc.. and with different hardware.
Would love to hear from someone with experience, a programmer or someone familiar with Apple's IOKit and modem inits.
Regards,
John

Detecting the presence of a SIM card in an internal WWAN SIM slot

Was wondering if anyone can think of a way to remotely and/or programatically detect if a SIM card has been physically inserted into a ThinkPad's internal WWAN slot?
ie Can we query through WMI or any other mechanism whether a SIM card is currently installed in a ThinkPad.
This question could equally apply to any OS / hardware version, but my current situation is for a number of ThinkPad T410s running Windows XP.
Any ideas appreicated?

Dell XT2 Upgrade to Windows 8, Embedded WWAN Not Turned On

I've been working on a friend's computer, and upgraded her Tablet/Laptop Inspiron XT2 (originally with XP Media) to Windows 8 Pro. The laptop has an embedded (believe it's the 5600) WAN card for Verizon. I got the driver installed from Dell's website, yet Verizon's Broadband software (VZAccess) tells me it's not turned on. I've checked hardware switches, the fn+f4 (or whichever combo it was), looked in network connections, checked using Unknown Devices to detect, and still no avail. In device manager, the only unknown devices are the fingerprint reader and the touch screen, which makes me think the wwan card is properly installed, just not being detected by connection manager. Any ideas on how to proceed?

Spectre 13" 3004TU Ultrabook F4A28PA Display rubber seal leaking fluid at bottom of screen

I have a Spectre Ultrabook 13" for which I paid a pretty penny - top of the line specs (i7, 8gb ram, 256 GB SSD etc).
Naturally, having spent so much I have treated it with kid gloves - however, I have noticed small amounts of a clear, oily residue appearing on the screen below the rubber display seal at the lower left and right hand side of the screen. It sits on the glass bezel and smears when touched. It also transfers to the laptop metal opposite the screen when closed, appearing again, as an oily clear fluid. I have not had any luck discussing this with HP reps (in India, presumably - I might as well be speaking Swahili, for all the help they have been).
My initial thoughts are that it may be a solvent which may have been used to attach the rubber seal to the display? is it the rubber breaking down? I have been advised there is no oil-type dampening fluid used in the hinge, so I'm at a loss. Of course, HP, ever helpful have already advised that although the laptop is still under warranty, I will possibly be liable for any costs. Wonderful!
Have been asked to call the HP 'Service Centre' in Brisbane, Australia for advice and to book it in. Naturally again, this service has been outsourced to a provider called 'AWA', and so far, after being on hold for over an hour, I'm still waiting to get through.
This will be the last HP product I ever buy, and no, I won't be recommending their products - on the contrary, I'll be sure to advise everone I can that if this is the standard of after-sales service, steer clear!

Can't connect to WWAN through the ericson mobile broadband adapter (f3507g)

hello,
I have a T400 P/N:7417-TNU with a built in mobile broadband adapter (ericsson).
i am using a local (israeli) sim card to connect, the sim is working just fine with an external modem.
when i try to connect through access connections it doesn't connect. i even put the settings such as the access point manually and still it doesn't connect. it says that it can't find a service provider, but on the sim account it sometimes show i the name of the service provider.
another funny thing, when i try to connect through dialup to the WWAN, it gives me a PPP error no.734, but if i try to connect through the access conections and fail... than i can connect through the dialup. could it be drivers colliding or something?
i have no problem working through dialup, as long as it is stable, and connects whenever i want.
can anyone help please?
thanks.

WWAN is not reliable in X250

Well, I spoke too soon about the "working perfectly" part in my previous post. If you close the lid (to sleep) while the Sierra EM7345 WWAN is Enabled, the computer crashes reliably next time you open the lid. Generally the crash is a BSOD with an unhandled exception in vwififlt.sys.
This happens whether Mobile Broadband is on or off in the network settings panel. It happens the same way whether plugged in or on battery power. It happens the same way whether wifi and ethernet are on or off.
Sometimes the driver disappears from Device Manager, replaced by either a CDC device or an unknown USB device. Sometimes restarting will fix this, and sometimes it won't. If it doesn't, you have to reinstall the driver to get it working again.
The only workaround I've found so far is to Disable the Sierra EM7345 Network Adapter in Device Manager when done using it, then enable it next time you need it. Not very convenient. I wonder if there's a way to automate that.
The EM7345 driver and firmware are the most up-to-date from Lenovo's web site.
Has anyone tried removing the Sierra WWAN card and replacing it with something else?

I am working on a better work-around. There are several alternatives I am trying.
1. You can enable the EasyResume feature under Lenovo Settings. If you close the lid while this is enabled, the computer goes into a power state that is more than sleep but less than idle. It comes back in less than 1 second when you open the lid, and the WWAN driver doesn't crash but remains connected. Unfortunately, this lasts for only 1 hour, after which the computer goes to sleep. If you open the lid after that, you get the blue-screen-of-death (BSOD). Note: from what I've read this feature only works on SSD systems (which I have), not regular hard disks.
2. You can set the computer to Hibernate when the lid is closed. In Edit Power Plan, Advanced Settings, you need to Allow Hybrid Sleep and then set the Lid Close Action to Hibernate. When you open the lid, it takes 5-10 seconds to resume. The WWAN reconnects immediately, faster than I can swipe my finger to log in. And it doesn't crash (so far). This option is not compatible with EasyResume; once you change the Lid Close Action, EasyResume disables.
3. You can set the computer to Shut Down when the lid is closed. When you open the lid you have to push the power button to start the computer, and it takes about 10 seconds to boot and another 10 seconds for the WWAN to reconnect.
The option that works best for me is #2 since it preserves the system state including open apps, so I'm going to try this for a few days to see how stable it is. Since I plan to use the WWAN a lot, I'll set the computer to never sleep under any conditions.
I am not sure how long Hibernate takes to resume on a HDD system, so it might not be as practical there. Someone else will have to try it.
One thing I've already noticed about the Sierra is that it holds its connection well even with a weak cellular signal. The GPS seems to work well too, although it does not have a compass so apps depending on a compass do not work.
