Lenovo T400 / T500 :: No Way To Turn On Mobile Broadband Switch On T420s
Aug 2, 2014
I have a t420s and so far I'm happy with it.Recently I purchased a MC7700 card from ebay with lenovo FRU. Everything looks smooth except that I found there is no way to turn on the mobile broadband switch.i believe I have a whitelist-removed bios otherwise it won't boot. The driver downloaded from lenovo website is installed fine, I can see the card working in device manager. I could read the iccid in windows network settings. Everything looks good, but I just can't turn mobile broadband on.
My laptop runs windows 8.1, I heard there is a thinkvantage connectivity tool that might work for windows 7 but not windows 8. I have quite a few files on my laptop and going back to windows 7 is the last option I would like to try.
I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.
I want to run a Virtual PC in VirtualBox and get the message, that I need to enable VT-x. I have updated to the newest bios (1.31) but i still don't have the option to enable "Intel Virtualization Technology" under the Config --> CPU menu.
We installed a Kinston 240 GB SSD in the Ultrabay, and it is not fully recognizing the SSD - it does not show up as a device, though we know the machine knows it is there, and we could use Linux and ghost to it..
We then ghosted to it with no issues. We then put it in the main bay, but it would not boot.
We looked at it from the USB port of another computer, and the files looked fine. Are we missing a driver?
Lenovo T420s is randomly crashing. There is nothing special in the Event Viewer. Only that the PC was not turned off properly. Not exactly BSOD.

Usually happening under some load (eg. game) but I have seen the same running only MS Office. No Macros or special calculations.
I would say this happens due to overheating. This is my second T420s I have same problem with. I work as 2nd. lvl IT so I know other colleagues are experiencing the same.
Frequency decreased once performance settings in power management were switched to balanced mode. Not solved though.
I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.
I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.
Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :
"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.
I need to do a recovery on a T420s. I want to recover to same state as out of the box. I already backed up all the data. I am using the disc provided by Lenovo but cannot seem get the disc to start the process. I think I set the DVD as the first boot device but it goes right past it and into the normal start up process.
Is there a way to start the process besides from boot up?
My 5 months old SSD crashed and I replaced it with a Macrium created mirror. Everything seems to work except the computer no longer recognizes USB drives. The USB drives are good (checked on other devices), I've removed and reinstalled all USB hubs and drivers - the chip drivers and bios are up to date and the USBs are enabled in the BIOS AND I've done several virus scans (online and local) in safe mode (Malwarebytes, Spybot, ESET, Defender, AVG, Housecall). The USBs are recognized on boot but once Win7 boots the USB for storage devices no longer work.... however, the USB recognize keyboards and the mouse. Guessing a new OS install will fix it, however, I would rather not reinstall everything.
I bought a Roline DP to HDMI cable hoping to be able to watch HD content in my livingroom and not having to plug an extra audio cable as DP should carry sound too.
When I do the same as on the youtube video, I get the following settings in the control panels: [URL] ....
But there's no sound coming out of the TV. I've tried it on my SyncMaster PC/TV Screen and on my Samsung TV in the living room. On the TV in the living room, the windows audio manager shows the device, but it cannot be selected as show above. It stays grey.
I've got a T420s with discrete nVidia Optimus graphics (Quadro NVS4200M). Driver version is 1.2.19.0 for nVidia HD-Audio and 8.17.12.6696 for NVS 4200M. This information comes from the device manager. I installed my system from scratch and used ThinkVantage System Update 4.
Where the problem comes from? I could only imagine that the cable isn't capable of carrying audio, but that seems rather illogic, does it?
I have been running ubuntu on my T420s for about 2 years now. Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it. Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers. I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.
Audio stutters when using bluetooth connection to my BOSE speaker (from Spotify). Has started lately. Cable works perfect. I use Thinkpad BLuetooth 3.0 version. Conexant 20672 Smartaudio HD.
I connect my T410 to an ethernet connection, open up Access Connections, and try to get the Mobile Hotspot feature working. When I click on "Start", the button just turns to "Starting..." and hangs there forever.

I have a T420 Thinkpad and have 2 external monitors connected; one using VGA into the docking station and one using DVI into the docking station. The laptop does not recognize the mobile PC display as an option when I attempt to extend to a 3rd monitor. The ultimate goal is 3 monitors extended: 2 external and 1 (the laptop display). Is this possible?
I recieved the W540 a few days ago, and I see there is a slot behind the battery for a SIM card, I tried using my SIM card and I still can't use mobile broadband. Can I use mobile broadband on the W540? do I need any drivers? and if I can't use it, can I buy something like this for the expresscard slot and insert the SIM in the slot behind the battery?
I have L440 with 64-bit Win7. Earlier experienced major WiFi connection problems, which were fixed with BIOS and WiFi card driver update.
Briefly after that Wireless Radios Master Control no longer lists Mobile Broadband, it only shows 802.11 Wireless/Wimax and Bluetooth.
Windows Network Connections lists "Mobile Broadband Connection" as "Not connected, N5321 gw Mobile Broadband Driver. Diagnosing this connection suggests to "Turn on mobile broadband capability", which I cannot do as it is not listed in the Wireless Radios Master Control.
I have a new X240. It has a sim card slot on the right side. I am running Windows 7 Enterprise 64 bit.
it seems that the x240 does not recognize wwan hardware. I can't find it in the device manager. It doesn't connect to any network when I insert a SIM card. Also, no unknown devices show up in the device manager. I installed the following drivers in an attempt to fix the issue:
-Ericsson N5321gw wireless WAN -Sierra Wireless 7355 - Gobi 5000
... but no success.
I also tried running commands in cmd window to check the status of the wwan:
-netsh mbn sh int -netsh mbn sh cap int=*
... but I always get the same message: "Mobile Broadband Service (wwansvc) is not running"
I am starting to think that having a sim card slot does not neccessarily mean that the x240 is Mobile Broadband capable.
First is while I'm docked in at work I use a normal key board and it has a right click botton on it. When I go home I do not have that button and know for previous models there is a short cut that you can do to "right click" rather than going to the track pad and right clicking.
Second is for the F1, F2, F3, etc... to work I have to hold down the Fn button. Is there a way to turn around the keys to where when I hold down the Fn key and press F1 it actually mutes the sound. I guess im trying to say is there a way to switch the primary function of the F row?
How I assume the switch between headphones and speakers should work: I turn on music or anything esle and if no headphones are plugged in, every sound comes from the internal speakers. Now if I plug in headphones then the sound comes exclusively from the headphones. If I pull then out again the sound comes from the speakers and so on.
In my case the situation is the following: If I have no headphones plugged in and turn on music, then I hear if via speakers. If I decide to continue listening to that music via headphones and plug them in, then the music continues to come from the speakers, but for example the notification sound from outlook comes from the headphones. This works vice versa.
If I open, say youtube to watch a video, while having the headphones plugged in, I will hear the sound via them. If I now unplugg them, the speakers will stay silent.
What can I do that if there are no external speakers plugged in (headphones etc.) every sound will be played by the internal speakers, if I plug in some sort of external speaker it comes from them and if I unplugg it it switches back to the internal speakers?
Just to clarify, my laptop is a Lenovo ThinkPad T420i, Type 4178. It is about 2 years old. I have Windows 7 64bit.
My laptop takes about 2-5 minutes to switch on, sometimes it doesn't turn on at all. The screen freezes every 15 seconds or so, but I am still able to move my cursor around. It also lags quite a bit. For example, typing 'how to download google chrome' will take me sometimes an entire minute, because only parts of the sentence will show up on the screen at a time. My keyboard is responding fine. The problem is not with the wireless internet, because even when the wireless is off the laptop is still unbelievably slow. Watching videos is impossible, because the screen freezes so much.
I have been having this problem with my laptop's performance speed for about 2 months now. I had it completed wiped back to factory settings, downloaded every malware and virus scanner known to man (none of them found any problems with it) and updated all my drivers.
How do I turn off the UltraNav pointing device? I just use the Trackpoint and its very frustrating to keep brushing against the UltraNav and move the cursor unexpectedly. Note that my T400 doesn't have either the Thinkvantage Productivity Center or the Thinkpad Configuration programs installed.
Just got a new T420 and tried the webcam feature but unfortunately it doesn't work. When Fn+F6 is press I only see the audio settings. I installed the latest driver from LENOVO and rebooted the system but it's still the same, just the audio settings. Updated the communication & hotkey as well.
My Lenovo T500 will not turn on, despite being plugged into the wall. Even when it's plugged in, none of the indicator lights show that the computer is plugged in. It also won't turn on using the battery.
I just got my new laptop today - but I can't open it to turn it on. My old T61 has a little latch on one side you just flicked and it opened right up. This has two silver things on the front, but I've tried everything and I can't get it to open. I've pressed one, both at the same time, pressed hard, pressed lightly. Been trying to open for over 20 minutes now but it won't budge.
Will I have to send it back solely because I can't open it?
I just bought a Lenovo ThikpPad T540p as a replacement of my old Lenovo ThinkPad R61i.What i'm looking for, is to turn off the internal Display if Windows 7 is locked. On my old R61i, it was the Hotkey FN + F3. I was easy able to changing the function of F3 in the "Energy Manager 6" on the R61i.I did not found any similar option on the new T540p.Because i use is very often when i run the laptop during the night and i sleep in the same room. Then i usually lock Windows an turn off the display.
Is there a way to turn on or off the wireless/bluetooth radio when the T420 is docked and using an external keyboard? I don't want to open the lid on the T420 every time to use the Fn+F5 keys when docked.
i have been doing research on this and i have decided that att's edge service is slow. but can anyone find a nation map for verzion's broadband access service and sprint's mobile broadband. now with verzions service i am asuming you get unlimited mb usage for $59.99. if you could use a sling just fine with att's service then that would solve everything but i dought you can. which one would you guys recremend? again i need the maps.
I have a XPS m1530, I had Windows Vista (Ultimate), I then installed Windows 7 and know I cant connect to my Mobile Broadband card. Does anyone have Windows 7 and Mobile Broadband working?
