Lenovo Thinkpad T450s, Sierra EM7345 and Windows 1...

Question: Lenovo Thinkpad T450s, Sierra EM7345 and Windows 1...

Hi all,I've really been helped by this forum in the past, and really hope you can help with this issue.I've installed the card and installed the driver - all of which has gone down without a hitch. The compute recognises the card with no issues. Unfortunately, however, when a simcard is inserted it does not register the simcard whatsoever - 'Insert sim' is still present.In my searches on this forum it seems this problem is Windows 10 specific - the system does recognise the wireless card but does not recognise the simcard reader. Anecdotally, it seems to work for others when using Windows 7 (although that wouldn't be a fantastic solution in my situation.)Is there any solution for this?Thank you in advance for your time and any responses!Jack

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hello, jraynerwin10 doesn't need wwan card's manufacturer drivers for the normal mobile connection, it has a native support that. Additional drivers are needed for the legacy location features via NMEA port, for the custom wwan card virtual devices configuration (like NDIS port etc).So, the 1st thought modem firmware is outdated. Check it out:open command prompt window (cmd) and type in the following stringnetsh mbn sh cap int=*Copy and past an output here (remove Device ID for your privacy).Another version is connection settings, APN mainly. Do you see a cellular network item in the win10 network settings?Anyway, I hope mobile device em7345 is present in the Device Manager w/out errors.

HelloI got a totally new T450s with Windows 7 preinstalled. I did immediately an updgrade to Windows 10. Now the Sierra cellular modem is not working properly after inserting a SIM card (which works fine on another laptop). It says "Cellular No Service". The driver that is installed is "generic mobile broadband adapter" and not the Sierra Driver. I downloaded the lates Sierra Driver from the Lenovo website and installed it. Without success, it always installs the "generic mobile broadband adapter".Anyone any idea? ThanksAlexander Avidan

Answer:t450s Sierra Wireless EM7345 not working after upgrade to Windows 10

Welcome, Alexander Do you see broadband item on the cellular settings pane?The most likely cause of issue is APN setting missing in the connection profile. What is your operator name and what profile settings do you see?Win10 doesn't need modem manufacturer drivers for broadband access only, it uses built-in drivers. Also, there are default connection profile settings in the OS. If your operator is missing in that base or connection profile settings differ, you should edit profile on the cellular pane under administrative privileges.Anyway, I'm not sure em7345 modem in the Device Manager's "Network adapters" category in the win10 with OS built-in drivers installed should look like "generic mobile broadband adapter".

May i know whether Sierra AirPrime EM7345 work with ThinkPad W540?













Solved!

Go to Solution.

Answer:ThinkPad W540 Work with Sierra EM7345?

Since it is listed in the official parts-list for the W540: Yes. However, you will need a Lenovo branded card (04X6014, which is the Sierra Wireless EM7345 LTE/HSPA+ 42Mbps M.2 Card).

Answer:ThinkPad W541 no driver Win7x64 support for Sierra EM7345 any more?

Hi aschulte,
 
If you have a W541 then you need the driver for the EM7355 card; that's what should be in the system unless the parts list and psref are mistaken.

I have a T440 with Sierra LTE. It works just fine for connecting to mobile networks.But here in New Zealand, one of our providers also provides free wifi hotspots to customers on certain plans. In order to use this though, I have to enter a password that is sent to me by SMS.Is there any way that I can view SMS messages sent to the SIM card that is inside my laptop?At the moment, I have to remove the SIM from my ThinkPad (with all the hassle that involves), stick it into my phone, get the password, then transfer the SIM card back into my ThinkPad (and often as not, there is no power socket nearby, so I can't restart because I had to disable the internal battery when removing/replacing the SIM card).So, if someone can point to a way that I can simply view those SMS messages on my ThinkPad, I will be enernally grateful.

Hello, I'm thinking to buy ThinkPad Sierra Wireless EM7345 4G LTE Mobile Broadband FRU: 04X6014 for my ThinkPad X250. I?ve few questions, Pease suggest ...1. Is it really any good and practically beneficial?2. Can I use it on Fedora 27, How?s Linux support?3. X250 has two PCI Express M.2 card slot and one is already occupied by WLAN Card and other slot is available, Can I use empty slot for FRU-04X6014?4. Can I use both WLAN and WWAN simultaneously?5. What is the impact on battery (Windows and Linux)?6. Is AliExpress a good place to buy? Thankyou  

Answer:Sierra Wireless EM7345 4G LTE Mobile Broadband FRU: 04X6014 for my ThinkPad X250

Regarding your questions:1) I personally use it and it's really good, as I don't want to use additional USB modem or WWAN wireless router.2) Can't say, as I don't use Fedora.3) There's a dedicated port for this module. Please make sure, that you have an antenna connectors for module and adapter for a SIM card. Moreover, instead of WWAN module, you can install there a m.2 2242 SSD disk.4) Both can be enabled and connected, but application will use one at time.5) I have an extended battery, so it's hard to tell. I guess it have a simmilar power usage as WLAN module (basing on Windows power utilization). Can't say about Fedora.6) It you don't want to have a problem with whitelist (it prevent system from booting, when unauthorized module is installed), then I look for module on eBay. Make sure, that photos explictly show FRU PN: 04X6014 on module's label. Models without it will not work.

How to flash the firmware of the sierra wireless em7345 on windows 10 ?  Its not possible through the steps i could find which was only for widnows 8. 

Answer:Sierra Wireless EM7345 windows 10

HiOnce the modem drivers are installed, including Intel flash tool, and the sim card inserted, during laptop cold start the flash service checks out whether newer firmware is available according to current modem fw and the sim card data (more clearly, cellular operator MCC/MNC values), and performs the flashing process if it's needed, in auto mode. You should see appropriate notification from the flash service in the system tray.

Hello! I have a T450s with a Sierra EM7345. After a vanilla installation of Windows 10 and Update 1607 I don't get a stable connection with 3G/HDSPA/LTE to O2 with this card. I have used the latest drivers 2.25.10910 and software 2.21.10890. The card shows firmware FIH7160_V1.2_WW_01.1528.04. Energy-Option is set to maximum performance. The connection to O2 is established very quickly, but I have a plenty of time-outs over this card.Does anybody have the same problem or has a solution? Thanks Axel

I upgraded my Helix Gen 2 to Windows 10 with few problems except for the Sierra WWAN interface to Windows 10 settings. The cellular button on the wireless menu is greyed out and the cellular option page in settings shows no devices. The adapter setting shows the adapter, and on the Settings, Network & Internet , Airplane mode page show both Mobile broadband and Wi-Fi buttons. WWAN can be enabled by truning off Wi-Fi and turning on Mobile broadband on Airplane Mode settings page. With these settings, I can connect to WWAN Verizon and get to internet but:1. Settings, Network & Internet , Cellular shows no connections2. Wireless pop up menu shows Cellular and Mobile Hotspot greyed out. So, in summary, I can connect to WWAN, but only via Settings, Network & Internet , Airplane mode page using proceedure above. By the way, my upgrade to Win 10, switched on the rotation lock, but I was able to fix that in Win 10 settings in table mode.

WARNING!!! The instructions in this post are applicable only to EM7345 installed in Lenovo laptops!! For example, models T440, X240, X1 Carbon 2nd and 3rd gen, X250. For tablets or other devices don?t use the firmware given in this post, you can brick your EM7345! Unfortunately, the default factory EM7345 firmware version  (1.1) has some bugs. For example, after connecting to a LTE network and then disconnecting manually, the network status of the connection was changing for me to ?No service? until device restart. Also, the device often disappears from Device Manager and reappears there with the name ?1 CDC? and does not work until you disable and then enable it again in Device Manager. All those issues are caused by some bugs in EM7345 firmware.But there is a newer version of firmware, namely 1.2, where the above bugs are fixed. But by default, you cannot flash it, because firmware updating is supposed to work unattended. And this is not nice of Intel and Lenovo. The users must be able to do firmware updating when they need or want it! Bad, bad Lenovo, very bad! Here?s the instructions of how to flash your EM7345 to the latest version:Make sure you?re using Windows 8 or 8.1Go to the control panel and uninstall Sierra Wireless EM734x 4G LTE Software from Program and Features.Reboot your laptop.Download and install the latest EM7345 driver package from the Lenovo website. http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-l...

Hi, jkuengWhat's the OS installed on your laptop? For win8/8.1 there are no needs for drivers if the card is in MBIM mode. It must work natively in OS. Let's check it. Look at the Device Manager, open Network Adapters item. You should see something with AiarCard. Open Properties, Details tab, pull down Options list, find out an item Compatible ID. Looks like USB\Class_xx&SubClass_xx&Prot_xx). Copy the values and past here. Will look.
 
Also, could you, please, post here USB IDs of this card? Find it at the same list under Hardware ID item (looks like VID_xxxx&PID_xxxx).

Hi Support, I would like to change a setting, so that the Sierra Wireless Adapter only connects to 4G networks. In Windows 10, I cannot see anywhere where I can easily set this. I would expect there to be mobile management software where these settings could be changed. I never want to connects to GPRS, and would like my Sierra Wireless mobile card to only connect to 4G or not connect at all. This would prevent the card dropping down to GPRS when the signal is temporarily weak and force it it to try for a 4G connection. I have had similar functionality on prior USB mobile data cards I.e. Vodafone, and hence the expectation that there would be similar settings on the Sierra Wireless. Thank you, George

According to this file W541 is supported by W8 or W10 but unfortunately I?m not able to install any other OS on the laptop.Can I expect to have support for W541 with W7 in a future software release? ThanksZoltan

Answer:W541 Sierra wireless EM7345 GNSS Sensor

I'm having the same problem with my Sierra Wireless 7345 on a W550s running Windows 10. It came with the laptop, so I'm sure it's supposed to be compatibile. I think it's a driver compatibility problem. Unfortunately, I've just chalked it up to the "Windows/Lenovo" tax - some things work, others just don't. I've gotten no reponse from Lenovo.

Hi , I have updated to the 1607 Anniversary Update in August and noticed that my WWAN Sierra Wireless EM7345 had problems starting up after reboot. Because of other problems with the 1607 I reverted back to 1511 and everything was alright again.A week ago I upgraded again to 1607 and again, my WWAN sometimes cannot start when booting up. The error log shows Miniport Sierra Wireless EM7345 4G LTE, {b343453c-24e6-493d-ba47-33eaec4de5e3}, had event Fatal error: The miniport has detected an internal error (details see below). So this clearly has to do something with the 1607 update or the drivers for the WWAN. I am using the latest drivers from the Lenovo website and have also tried to update drivers in device manager. But no luck. What helps to finally start the WWAN is either a reboot (the chances the WWAN is started properly are about fifty-fifty) or clicking WWAN off and on in flight mode options of Windows.  Maybe someone has an idea other than waiting for Microsoft to fix this stupid 1607? Thanks and best regards,Martin  Log Name:      SystemSource:        Microsoft-Windows-NDISDate:          10.10.2016 06:37:19Event ID:      10317Task Category: PnPLevel:         ErrorKeywords:      (16384),(16),(4),(2)User:      ...

Hello everyone, I'm a bit desperate because I already tried so much.I'm running Windows 8.1 on my Lenovo X240, BIOS version 2.3 and the WWAN functionality broke about two weeks ago and I'm quite sure that this is related to a few updates that came either with Windows or more likely with Lenovo System Update which had a BIOS update and some driver updates alongside at that time.I cannot even try to establish a connection to the Deutsche Telekom LTE network, because all I'm seeing is "Insert a SIM" in the connection bar.This is what I tried so far:Use a different, well known working SIM card.Re-Install the driver packageUninstall and re-install the driver packageuse the "repair" function of the driver package setupBIOS downgrade from 2.3 to 2.29Disable and enable the WWAN functionality in the BIOSReplace the mainboard (lenovo service technician just went away an hour ago)And I'm still having the same issue. Now it's really nailed down to be either the BIOS or the driver in win 8.1 x64. One thing makes me wonder:When I choose to update the driver in the device manager and the Sierra card details, I'm pointing Windows direclty to the directory that contains the inf files and the device manager tells me that "The best driver software for your device is already installed." and shows me a "Generic Mobile Broadband Adapter". Is this an indicator for Windows completely ignoring all drivers in the setup directory of the driver package?Also, when I lookup the driver details, i... Read more

One of the three antenna connectors on the MC7710 is for the GPS antenna. This could mean that it could work fine with the two antennas that are available.

Does your T450s actually have the WWAN (cellular broadband) module/card  installed?      Not all models came with that option, so need to vefify that your T450's came with that capability, otherwise the slot is useless until you upgrade it.

 Hi There - I just bought my Lenovo Thinkpad T450s. I learnt that ......since the keyboard is with the backlit, it would be fragile (when compared to the one without the backlit) and it would need a protector cover. I also prefer to have it for avoiding the dust. I am not sure, if the cover protector would not let the heat generated to let out and will break the graphics board. By the way, could anyone please clarify that doubt and also suggest me a appropriate cover for my item (T450s) in amazon or anywhere else ? I was looking to buy the item displayed in the lenovo website itself, but unfortunately it is only in the US site and not in the canada site. I live in canada. Please help me with your suggestions. Thank You so much.  bye !!

Answer:Lenovo Thinkpad T450s Keyboard cover!!

Hello,
 
I suppose it depends on how you use and travel with your laptop and under what conditions. I would think a sleeve, backpack, padded laptop tote,or laptop case would suffice. I've never had a problem with backlit keyboards on ThinkPads or Yogas. I can understand your concern with wanting to protect a new device, though. If Lenovo does not have what I need, I usually try to find it at Best Buy, Amazon, or Walmart. That's just my opinion. Perhaps others will have additional suggestions.

Even when I change the display settings to extend the desktop.  There was one brief occurrence with the new screen, where I saw a very faint lenovo logo appear when the splash screen loaded. But then it went completely black again. And has not done even the faint image since, it was just a fluke occurrence.And when I shine a flashlight, I still see no display. While the external monitor is displaying the desktop and I then reopen the laptop lid, the laptop screen is recognized as being there.

Network do not found when starting the laptop which is docked.You need to unplug network cable from docking station and put back...that normally helps.Without docking station the networks works well.Also sometimes keyboard and mouse stops working (those are connected to docking station.

Answer:T450S in Lenovo ThinkPad Ultra Dock, network missing at startup

I have a very similar Problem with some T440s and Ultra Dock.Although replugging the cable to the Dockingstation doens't work for me. The Notebook is running Windows 7 64 Bit Enterprise and is ( or should be ) plugged to a 1 gb LAN with Cisco Switches. Using the Networkinterface on the T440s works fine until i use the Dockingstation. The Problem seems to be the auto negotiation between the Dock and the Switchport. When autonegotiation is disabled in Windows ( setting to 1gb/s fullduplex didn't work though) and setting the Adapter to 100mb/s fullduplex, the connection is stable.  With autonegotiation activated Windows tells me there is no Ethernet Cable attached, so there is or seems to be no physical link.

My year-and-a-half old T450s stopped booting up. Yesterday I was prompted for a Windows update and restarted the machine, as usual. After the update, I'm able to turn it on but it wont boot up. It shows the initial screen, with the "Lenovo" logo and won't proceed beyond.I tried taking out one battery and then holding the on/off button for 30 seconds, and also the emergency reset on the bottom, but neither changed anything.

Try plugging in an external monitor and see if you get display, I did in my case.  Remove your hard drive and restart the PC, this should get the bios working again, go into your bios and disable secure boot so you can boot to a USB. Create a bootable USB 3.0 using a USB3.0 drive (formatted to NTFS) from Microsoft's site - https://www.microsoft.com/en-us/software-download/windows10/ Then goto repair my computer and choose rollback update, this will get you running again.  I have a p50 with Nvidia M1000M dedicated graphics, so I am still trying to figure out if this is a driver issue.

Hello there, and many many thanks for your time if you try to help me on this issue. It's much appreciated! I've had a Lenovo T450s for a half a year, specs are the following: - Windows 10 Pro x64 build 15063 (clean installed after system restore was stuck and couldn't access windows)- Intel i5-5300U (2.3Ghz).- Intel HD Graphics 5500.- 8GB RAM.- Samsung mz7ln256hchp-000l7 SSD 256GB.- BIOS 1.28 (latest)- Drivers up-to-date, taken from lenovo.com and intel driver update utility.The problem usually happens when a video is playing, music is on, or can be imitated by playing flash games, but can sometimes happen when the laptop is idle. In safe mode there is no problem with it, but once when the laptop was on the sun, it even had a BSOD in safe mode. Temperatures seem to be acceptable, CPU/GPU reaching a maximum of 70 degrees and an average of 40-45.The blue screens are usually connected to the intelppm.sys, ntoskrnl.exe, but sometimes even the netword driver (Netwtw04.sys) or once even the graphics kernel mode driver (igdkmd64.sys). I've run the prime95 test once, it did not cause BSOD and was running the driver verifier as well, which at the beginning was causing errors.

I have a W520 and am looking to purchase a WWAN card.  I see that Sierra Wireless has the MC7750 card available (supports LTE, EV-DO and HSPA+).   Will the W520 support LTE, or am I just wasting my money getting a WWAN card with LTE support?

Answer:ThinkPad W520 and Sierra Wireless MC7750

The short answer: get the MC7750!Probably the biggest improvement isn't the raw download/upload speed of the unit, but rather the reduced network latencies. All the advertisements are only talking about the improvements in MBps, probably because it's the easiest thing to describe to people in 30 seconds or on a billboard. In reality MBps only matters if you are watching video, or downloading large files. Most of the delay time for other applications comes from the several hundred milliseconds it takes the computers to make a round trip communication. Each time you click something on the web, there are several rounds of communication which can add up. If your current connection has a 400ms delay (as mine does) it takes several seconds each time for anything to happen. Some better connections like HSPA are supposed to have about 100ms latency, but LTE is going to push that down to about 40ms.  Can you tell that I'm excited about getting LTE  I'm planning on getting the MC7750 as soon as Lenovo releases it. Unfortunately, every time I call in, I seem to be told that it's just a month or so away. I've been hearing that line for almost 4 months now. I was also told that I will be able to upgrade my existng x220, which had better be true otherwise I'm going to be royally pissed because I bought the system with that understanding.You may find my thread on the MC7750 for the x220 device interesting.http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Does-quot-Bro...

I got a W520 and installed the card, drivers and hardware is seen properly (I'm using Win7 x64bit)but it keeps looking like it is turned off (how you turn off wifi).  Though when I press FN+F5 it doesn't show mobile broadband, only wifi and bluetooth I use the AirCard Watcher app and it keep saying Airplane Mode, radio is off.when I disable and enable the card via network settings.    The Aircard watch see the card for about a split second when I reenable it but then it goes right backto airplane mode.. I also tried using the Lenovo access connection and when I try to connect to mobile broadband . it keep saying no signal or sim not activated  BTW: I have a working Verizon Sim card that I use for a usb dongle and I have a x240 with broadband card that works fine with the SIM  so it's not a sim card problem.

Hi Guys,First off, thank you for this very wonderful resource. Now, I will try to make this short and simple and hope someone can help me out.I currently am using a T430s which I ordered a Sierra MC7550 (GOBI 4000) mini PCI card for to have internet (4G) on the go via verizon.I followed all instructions and installed the card without any issue. I booted the notebook and notice a little popup in my tool tray that said the hardware was not successfully installed. I then tried using System update to install the driver which seemed to have installed everything successfully. I opened my network connections and still didn't see the new device so I decided to open up device manager and saw that something was wrong.The MC7750 was listed under "Other devices" instead of "Networking" and had the yellow exclamation point next to it.Currently the exact error is as follows:The drivers for this device are not installed. (Code 28)There is no driver selected for the device information set or element.To find a driver for this device, click Update Driver.I tried manually downloading/installing the driver from Lenovo's site, using System update, manually pointing to the downloaded driver's path and nothing seems to fix it.I am hoping someone could help me here. I'm not sure if this is Lenovo branded or not however I'm not getting any BIOS errors upon boot. I'm running the latest BIOS and Windows 7 Pro 64bit.There's not much information on this card via the net and I assume this is because of it... Read more

Answer:ThinkPad T430s + Sierra MC7750 WWAN Issues

UPDATE: After hours and hours of research and contacting lenovo support via phone to no avail I decided to install the MC770 driver (same device, but for AT&T) and downloaded the installation file from AT&T and VIOLA! It installed and I was able to see it in my device manager under Network adapters.I'm not sure if its fully working yet because I had no idea I needed a sim card.. I thought i could just call up verizon with my IEMI number and have it activated... either way I consider this one step closer and it leads me to believe that something is up with the driver download from LENOVO. Also, could I buy a prepaid Verizon sim card and use it in here or? IF this works fully and flawlessy, I hope this helps someone to prevent them from going through what I went through. Hopefully Lenovo updates their drivers.*** I ask that you guys still kindly reply to let me know if I am missing something here. Thanks.

[OS: Windows 10] Is there an application to use for sending/receiving SMS messages with the Sierra EM7455 Wireless WAN card? What I am looking for isn't one of those bulk sending applications that connects to some server ove Internet. What I want is to send and receive SMS messages just like the way I can do so on my phone. I am really hoping someone knows of such an app, because all googling efforts turned out to be useless.

Hello, Has anyone tried installation of a sierra wireless MC7750 card on a X220 tablet? I've gotten hold of a MC7750 and intend to install it on my X220 tablet and try it with Verizon 4G network. Thanks,Anand

Answer:Thinkpad X220 Tablet - Installation of sierra wire...

I have not tried it, but I can tell you that most likely it will not work in the default configuration.  Lenovo machines have a whitelist that checks to see if the WWAN card inserted into the machine is regonized and certified.  If the machine doesn't recognize the card it will display an 1804 error.  Since Lenovo doesn't yet sell these cards yet, it's unlikely that this card is on their whitelist. Some people modify their BIOSes to recognize cards that Lenovo hasn't put on their list yet.  I believe you can find such moded BIOSes here: http://www.bios-mods.com/forum/Thread-Removed-whitelist-removal-Lenovo-ThinkPad-x220-v1-21 or alternatively maybe in the forums in http://www.mydigitallife.info/ There may be newer versions of the BIOS in the same forum, but I haven't checked in a while. I've been waiting for months for Lenovo to support the MC7750, or another LTE card like it.  I've been told by several sales people that "it's right around the corner".  Pretty much hogwash so far.  I haven't gone the step of ordering one of these card yet hoping that Lenovo will officially support it soon.  Please post back though if you do end up moding your bios.  I'm curious to know how well it works.  Also read up on taping pin 20.  Some people say it's necessary in addition to moding the bios. Good luck.

Received my t450s last week, and haven't determined this was an issue till last couple days - have looked around the forums to see whether I'm the only one, or others have this issue: The "v" key doesn't seem to work like the others.  One of my most used passwords begins with "v".  I was getting a sign-in error for a few websites I log into, and so I'd have to enter it a couple times.  Then I noticed that the "v" will only register when it's pushed down a certain way - if I push straight down on it, it'll work.  If I push on the left side, it doesn't register the keystroke (unless I push hard down to the bottom of the stroke).  All the rest of the keys work perfectly. Am I just being too picky?  I don't think so, as I'm just comparing the stroke of one key to the others on the keyboard, and determine there's a difference.  Any comments or solutions?  thanks

As I understand, hardware fde works by using a media encryption key that is stored in the disc controller.  Access to this key is controlled by a key encryption key which the user should be able to set.  (Without setting this key, fde is pointless as the drive will boot without any user intervention). How does one set the key encryption key on the T450S?  And can it be configured so the key has to be re-entered after the wakes from sleep or hibernation, as well as at boot time. Thanks,

Answer:My Thinkpad T450s has a SIM Slot

Welcome to the forum!
 
While some ThinkPads come with full WWAN support, many are shipped "WWAN upgradable" with a SIM slot and antennas, etc. but without the hardware card needed to connect to a WWAN. This allows the customer to add a WWAN card in the future. Are you sure your ThinkPad is the former?

Hi, I'm actively choosing a laptop and found that T450s is almost an ideal candidate! Just have a few question about it: 1. Is there a BIOS option to swap Fn and Ctrl keys (manual says Yes, but could someone confirm)?2. Is there is a way to configure a keyboard to use F1-F12 keys without pressing Fn key? If so, then what is the way to achieve it (BIOS, Driver or Lenovo Software)?3. If the laptop is ordered with the 256GB SSD, then is it M2 or 2.5" SSD?4. If I order a laptop with 4GB or RAM, would it be possible to install addtional 8GB module later? If so, is it 1600Mhz CL9 or CL11? ECC or non-ECC? Is it 1.35V? Thanks in advance!

Answer:Few questions about ThinkPad T450s

Hello and welcome,
 
The T450s base specifications should help with some of your questions:  http://psref.lenovo.com/PSREFUploadFile%5CSys/PDF/ThinkPad/ThinkPad%20T450s/ThinkPad_T450s_Platform_...
 
3: pretty sure the m.2 slot is intended for a cache SSD, not the main drive.  If you order it with a 256GB SSD, it will be 2.5"  (That said, if I lay hands on one of these, I'll install an m.2 boot drive...)
 
4:  4GB soldered, one available RAM socket.  Specs are in the link above, but not sure about CL9 or 11.  Not ECC.  1.35V.
 
Please double-check the above.  I don't actually have one of these to verify.

I'm about to buy a ThinkPad T450s. It's critical to me that I can connect 2 monitors (for instance 2 x Dell U2414H) using the DisplayPort. 2 x 1920 x 1200 is enough, and the laptop screen does not have to work simultaneously. Can anyone confirm that this setup works? I've been looking for hours for a page that clearly states the DisplayPort version of the ThinkPad T450s. I have found reports that some configurations of the ThinkPad T450s support DisplayPort 1.2 (which is what I assume I need), which is a good sign. However, the configuration of T450s I'm looking to buy does not specify the DisplayPort version. Can I assume that all configurations of the T450s use the same DisplayPort version?

Answer:ThinkPad T450s and multiple monitors

Yes, you can buy a DisplayPort splitter for that:http://shop.lenovo.com/us/en/itemdetails/0B47092/460/8FA0422CA6EA48B0BDED71D287F73673Optionally, you can always buy a docking station (only works on the non-Nvidia model). If you have discrete graphics, then you do not have a docking port.To find out your DisplayPort version, you can find it by looking up your processor microarchitecture which is Broadwell. It is indeed 1.2 for every ThinkPad T450s.

Hello Lenovo Fourm,I have a ThinkPad T450s with a fresh install of windows 10, I upgraded the hard drive because I need more space (also upgraded the ram while I had it open) so I did a fresh install of windows and all was well.  A few weeks into the fresh install of windows, the laptop's sleep functionality was failing. For instance, if i were to close the lid and let it sleep for 5 minutes the laptop will wake up - however the display will remain completely black. No blacklight, no nothing. And no it's not a backlight failure. If i were to hook up an external monitor to the system its perfectly usable, and if i were to go under device manager to check for the internal display it won't show up.  After fiddling around with drivers and updates, I did another clean install and installed all of Lenovo's drivers that wern't bloatware (including a BIOS update) and the sleep issue still persists. Something interesting: The error only happens if i were to close the lid, putting the laptop to sleep via the windows menu and using the power button to turn it on works perfectly fine. Here's a list of things i've triedFresh installation with Microsoft drivers (fail)Fresh installation with Lenovo drivers (fail)Bios settings tweak, such as changing the "Entry after" setting to immediately (fail)Trying the old ram that came with the system (fail)Turning off fast boot (fail)Trying various versions of the Intel Management Engine Interface provided by either ...

Hi! I have bought a T450s with Win7 and a ThinkPad USB 3.0 Pro dock recently and I have had some problems with the dock.BIOS and drivers are up to date on the computer and the dock can work sometime but only when the dock itself installs drivers from Windows update. If I disconnect the dock from the computer more than a couple of minutes it won't work again, it shows up on Devices and Printers but the external screen, ethernet, mouse and external keyboard wont work anymore. What I've discovered is:- When the dock works there is atleast 5 different things listed under the hardware tab of the device (can't remember what, and I can't get it working again)- When it's not working but the dock shows up on the Device and Printers there is only 2 things listed under the hardware tab, USB 2.0 nav and USB 2.0 nav. These are also listed there when it works.- I don't know why the dock doesn't run on USB 3.0 at any point.- When the dock works I can't update the firmware, it just says "No device found" when running the firmware update. What I've done so far:- Completely removed/reinstalled all drivers several times- Checked that BIOS is up to date- Checked in the BIOS if USB 3.0 is enabled- Sent the dock back to Lenovo and have gotten a new one, still same problem.Anyone have some ideas of what's wrong? Google and I'm running out of ideas..

Answer:ThinkPad T450s screen does not display

Hi Senyo,
 
Welcome to Lenovo Community! And happy to have you here.
 
As I understand that you are facing issue with your display in T450s.
Looks like you have a bad LCD panel & it needs to be changed so better contact Lenovo & replace under warranty.
Also you can try moving the LCD lid at certain angle whether display is coming or not.
 
I hope the above information helps.
Please feel free to post in Lenovo Community Forums if you have any further queries!
