T440s wifi

Q: T440s wifi

So I'm having trouble with my wifi card on my t440s.I began by putting the windows 7 x86 hard drive in the laptop from my x220, the wifi didn't work so I uninstalled the old drivers and replaced the drivers with the recommended t440s drivers on this site. The wireless worked, I then installed all the stuff lenovo bridge suggested, the start bar stuff annoyed me so I took it out. From then on no operating system, or drivers I have installed, have been able to find the hardware for the Wifi drivers.The bluetooth is working and I have tried using the bios to make sure the wifi function key isn't broken.I have also tried installing windows 7 x64, which is what im working with now, to try and find the hardware.When I go into network adapters, its literally just not there.

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

I've been trying to use my T440s away from the dock and each time I do, after a while the Wifi just dies and I need to switch on airplane mode and then switch it back on for it to start again. This is extremely annoying. I have the dualband  Intel AC 7260 running the 16.8.0.6 driver version. Can this really _really_ be happening with a machine that cost as much as an MacBook Pro? I feel cheated on so many levels with this machine. It goes beyond the wifi-problems. The clunky keyboard instead of the Lenovo hallmark keyboard from T420 and worst of all: the missing keys from the touchpad. What were you guys thinking? Anyway, back to the problems at hand. I'd really appreciate some input if you have come across this very same problem and have found a solution for it. Thanks.

A:T440s losing wifi connection

Unfortunately I have this problem too.  The connection simply drops out between 1 and 4 hour intervals.  It is rather annoying as the vpn connection cannot be reestablished for at least 5 minutes after a dropout, and I lose all of my work environment setup which can take another 10 minutes or so to rebuild.   Not sure it is lenovos fault, but they should be working with intel to fix this.

T440s, win 10. Recently, I can't connect to the university's wifi anymore. Sometimes I can connect but it says "No internet", while my friends around were using it. I borrowed a usb wireless adaptor and it worked good, no problem. I can connect to the wifi at home and some other places, but not on campus. I uninstalled the driver but it just reinstalled automatically after reboot. Anyone know how to fix this? I have read someone said it might be because the MAC address is blocked. Is that possible and why? Thanks.

Hello, I've owned my T440s for a few weeks now and it's a great laptop in all respects but one: My WiFi stability is horrendous. I've done a clean install of Windows 8.1 and downloaded all the appropriate drivers from the Lenovo website. The symptoms are as follows: - I will connect to a WiFi access point and begin to work.- At some point during the day the WiFi card will simply just stop sending and receiving traffic. I can open a cmd window and ping my default gateway and all packets are dropped. - While this is happening Windows still shows my WiFi link as CONNECTED. - Putting the laptop into airplane mode and turning it off again seems to fix the issue.- This happens with a NUMBER of wifi access points, so I'm fairly certain it is not the infrastructure My old gateway laptop which this T440s replaced has never had a single issue connecting to, or remaining connected to any of these wifi networks.  I've tried a number of things: - Installing drivers from Lenovo's website (currently up to date as of 12/12/2013)- Installing drivers directly from Intel's website- Letting Windows manage my WiFi- Letting Intel ProSet utility manage my WiFi- Disabling the ability for the system to put the WiFi device to sleep to conserve energy. I'm getting rather frustrated and some searching reveals a handful of people who have the same problem, but not enough that it is some kind of inherent fault in the card.  It's getting to t...

Just moved, and my laptop can't stay connected to my new apartment's WiFi. It connects for about two minutes tops before disconnecting like clockwork. I think I've tried all of the general solutions that come up when I google this issue (reset adapter, update drivers, make sure power management isn't turning adapter off) but the problem persists. My laptop doesn't experience problems connecting to any other WiFi. And the WiFi in the apartment works well with my phone and all of my roommates laptops. My laptop is the only device with the issue. The router is a TC8717T and my laptop is a Lenovo ThinkPad T440s running Windows 10 with Intel Dual Band Wireless-AC 7260 wireless adapter.

Dear Users, Since a few moments I am a (happy) owner of Lenovo?s new and business class model T440s. As I could find out, Lenovo is building in two different displays. On the one hand there are several model with aLG-DisplayModel: LP140WF1 (sp)(k1)P/N: 0C00349FRU: 04X0626 And the other from AUOModel: AUO B140HAN01.2FRU: 04X0436 (You can look up your displaymodel via BIOS, Everest or any related program) As far as I could find out in the world wide web there are several users reporting with a LG Display in their T440s that it is in quality inferior to the AUO Display. It seems that Lenovo is ready to replace the LG with an AUO display, sending out a tech. My question is what your experiences are and what can we, the owner of a  LG-Display, do?Is there a real quality gap between these two types of Display? My T440s, as i mentioned, has a LG Display. I can live with this one, if there are no great difference in the quality to the AUO Display. I am excited about your opinions.Thanks Fire

A:VERY DIM SCREEN ON T440S

Make sure drivers are updated and not using a generic VGA driver. This would make the dock not work and not be able to adjust screen brightness. If it is to the point where you can hardly see it at all then it most likely is a bad screen.

Hello,On my T440S, since BIOS v2.37.1.13 (with little hope that v2.39 would fix it, I installed it to no avail), I can no longer enter hibernation.When I try to do so, the red LED blinks multiple times and then the computer immediately wakes up. The event viewer only shows:The system has returned from a low power state.Wake Source: UnknownThe workaround is to either unplug all usb devices, or disable USB 3.0 support in the BIOS, which sucks for a 1000e + laptop.Otherwise, the computer enters a sleep-hibernate-wake up loop which is draining the battery.When do you plan on releasing an update (BIOS or USB 3.0 driver) to fix this hibernation issue?Thank you.

Apologies if this question has been previously answered.  I searched and couldn't find a response.   I'm still using the original HDD that came with the laptop.  I'm thinking of upgrading to an SSD and cloning the HDD to the SSD.  My question is what to do, if anything, with the, M.2 16gb cache that came with the laptop.  Should this drive be left alone as is in the laptop after the HDD to SSD upgrade?  Should it be removed?  Should anything be done to the M.2 drive if I upgrade the HDD?  My understanding is it currently speeds up the computer at start-up and with an SSD, this wouldn't be all that necessary.   I appreciate everyone's time.  Thank you.   -Rich

Hi Swazi,
 
Welcome to Lenovo Community!
 
I?m sorry to hear that you are facing the issue with not responding on your ThinkPad T440s.
 

Please check with connecting only power adapter.
Check with removing the battery and connecting only power adapter.
Check with removing both power adapter and battery, press and hold the power button for 30 seconds and after 30 seconds connect only power adapter and try to switch ON the system.

If the issue still persist after performing above troubleshooting, then it might be issue with system hardware so we request you to visit nearby authorized Lenovo service center.
 
Click here to open a link where you can select the country and get the exact contact support number. I?m sure they will be a great help.
 
Hope this helps!

Hi Dsc,
 
Welcome to Lenovo Forums.
 
Undocking a portable computer while it is in either standby mode or hibernate mode can result in data loss and system instability. To avoid loss or damage, use Undock to undock your computer, or shut down the system and undock the portable computer while your system is off.
 
How exactly are you undocking the computer? Are you undocking the computer using undock option?
 
Also, please update the latest BIOS.
 
Let us know how you get on.

Hi everyone, I'm trying to figure out if I have a unique problem, or whether this is a broader T440s problem. Occasionally, especially when my T440s has gone to hibernation from sleep, I cannot turn on the computer unless I plug it into the wall. That is to say, when I hit the power button when the computer is unplugged, NOTHING happens. I've tried holding the power button down, pressing it repeatedly, removing the external battery and then pressing the startup button, etc.  If I plug the computer into the wall, it starts up fine and shows that there is sufficient battery life. This does not happen consistently, and is difficult to repeat. For example, the computer went into sleep the night before traveling. I tried to start it on a plane flight (domestic, thank god, so it wasn't a huge issue, but if it had been international that would have been a disaster) and it simply would not start. Later, on a train, I was able to plug it in and it started with no problems and showed plenty of battery life. I then put it into sleep, it went into hibernate, and I was able to start it up without being plugged into the wall when I returned home. Has anyone else encountered something similar? Are there settings I can change, or should I have it sent in for repair (also, what on earth might cause this problem? Faulty power button?)

This is what happened to my T420.  Just about drove me nuts.  Since it would start in one power mode but not the other that proved that it couldn't be the button, right?  Another mod with more sense suggested replacing the keyboard anyway.
 
It was the power button.  On careful visual inspection I could see that it was slightly depressed from normal.  Either partly shorted or high resistance.  Plugging in the AC mains must have changed the voltages just enough for it to work.  Sometimes, anyway.
 
Not saying this weird problem is what you're seeing - but it might be.
 
Good luck,
Z.

I have an issue with my new T440s, Win8.1 Pro fully up to date with the latest Synaptics 18.0.7.40 driver from the Lenovo update. I am using a freshly installed copy of Windows rather than the provided image. Sometimes when working with the touchpad and clicking the pad down to drag something, it's as if ClickLock has been turned on from the mouse control panel settings, where it acts like the mouse button is held down until you click (not tap) it to release it again. ClickLock is turned off in the control panel. I found that the issue is greatly reduced (but not gone) if I turn momentum all the way down under Advanced -> Motion. This is driving me nuts as it's seemingly random. If I click and drag to select text then go to move the cursor, sometimes it acts like the mouse button is still held down and I change my selection. Or, sometimes I just want to move my cursor and it ends up dragging something or selecting text. Anybody else experiencing this? Lenovo please can you sort this out. I find myself using the touchscreen more and more as it's simply more reliable than the trackpad!

A:T440s Trackpad - ClickLock bug

Still experiencing this, but not heard anyone else mention it?About 25% of the time when I drag to select text by pressing down the pad, it still acts as if the button is held down after I let go and I have to click it down again. The fact it is so unpredictable is so frustrating, I end up having to double tap the pad to start a drag motion instead.

Could be a bad hard drive or RAM (both of which can be tested using Lenovo Solution Center), but I would start by noting the time of the hang, and then rebooting and checking the Windows Application and System event logs upon restart to see if there are any errors reported that stand out.    I once had an issue similar to what you are seeing, and the logs pointed to a hard drive controller error, which in the end was not the controller, but a bad/loose ribbon cable that seemed to act up when the system got hot. Open Windows Event ViewerStart >> Run and type: eventvwr Press Enter Good Luck,

RELEVANCY SCORE 35.6

Hello! I have following issue with my new T440s' speakers:a) having generic audio driver, there is silent noise everytime some sound is played approx. for 5 secondsb) having most recent Realtek there is permanent the same noise unless it is muted using Fn+F1. Only "software mute" doesn't work. I have Windows 8.1 x64.I tried some googled tips with disabling the microphone but none of them has worked. This is very annoying, since there is SSD and ULV this is the only noise this laptop produce. Thank you! Drozi

A:T440s speaker noise

I have exactly same problem. However, I don't think that this is driver problem since this buzzing is heard even when laptop is in bios. From what I can tell, sound(buzzing) is comming directly from speakers.(both of them) And you are right, it is extremly annoying and it is killing this otherwise very quiet laptop.
