T440s RAM Module suddenly not recognised

Q: T440s RAM Module suddenly not recognised

I have a Lenovo Thinkpad T440s University 20ARS0BH00 with 4GB Ram soldered in and an extra 8 GB as a SO-DIMM in a slot. About a week ago my system was feeling very sluggish and I went and checked Taskmanager and noticed that my ram was full while just browsing. I fired up cpuz and weirdly only 4GB Memory was displayed. Then I went to BIOS and even there only 4GB was recognized. I did not drop my laptop so a loose RAM module was unlikely, but I opened the case anyway (with antistatic wrist strap attached), carefully removed the DIMM, cleaned everything with pressurized air and put the Ram back in. After booting back into BIOS, still only 4GB is displayed.Does someone know what the problem could be?

Preferred Solution: T440s RAM Module suddenly not recognised

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.)


Hi there...

I bought a OCZ Vista Upgrade 667 MHz 2gb Module off amazon and i put it into my machine, and it only recognises 1.25gb of it.

I have 2 x 1gb in there already running at 800Mhz, i was thinking the difference in speeds could be the cause of the problem, but i though it would just drop the 800mhz to 667mhz....

i have tried different formations of the ram in the slots, keeping the 2 x 1gb modules in dual channel slots.

My mobo is Asus m2n-sli deluxe and im running Vista Home Premium 32-bit.

Also when i do a scan on crucial, it sees that i have 4gb overall, vista only sees 3.25gb.

Thank you advance...

this is my 2nd time asking for help since my 1st attempt got deleted for no reason.  my t440s developed the media test failure, check media cable. but unlike other threads, it did not occur because of a change in motherboard, ssd or any component. it was displaying some pdf files then the next moment it suddenly displayed the media check page in bios. I didn't even see what happened, whether it had a BSOD or anything. I opened up the laptop and there are no visible signs of damage or loose connectors etc. I've completed all diagnostics tests and passed with no issues whatsoever.

I have a t440s with the original 256GB ssd since the day I got it. this laptop has given me almost no issues apart from a lan port that seems to reject any connections lately. the laptop was displaying some pdf files without being connected to the internet via wifi or ethernet. I turned around and it was at the bios displaying the follow error.  Intel (R) Boot agent Ge v1.5.53 copyring (C) 1997-2013 , Intel corporation............. initializing and establishing link... PXE-E61 - Media test failure, check cablePXE-M0F - Exiting intel boot agent Boot menu correctly lists the SSD and PCI Lan (why is it there?) I know this is a fairly common issue, but it seems to appear because someone changed the ssd or motherboard or some part. I've not changed anything. not even the ram. even the batteries are the same ones I got from lenovo. I tried opening the laptop to check on the ssd and its connection but I can't see anything wrong. no loose cable (the connector is fixed on to the motherboard). I;ve also completed the lenovo diagnostics and passed it with flying colours. The bios menu settings for storage areUEFI and legacy,legacy first

Hello all,
for some unknown reason our Canon MG5150 InkJet Printer doesnt get recognized by any of the computers or laptops in our house. i have re-installed the drivers on several of those pc's but its had no effect.

during the driver install the software fails to detect any device. but any other time you plug the usb cable in a message box appears saying USB Device Not Recognized.

i recently bought a new pc tower, using win7 Pro and 64bit system with 32GB ram, i downloaded the 64 bit drivers for the printer from the Canon website but even that gets the same errors when installing the drivers.

my 10 year old son was printing stuff off about 3 weeks ago and since then we've had this problem. ive even tried searching for ways to reset the printer back to factory defaults but had no luck with that either.

can anyone give me some advice as to how to fix this issue.

I am running Windows Vista, and don't know if this is a hardware problem, a software problem, or a malware problem. Hopefully someone can tell me.

I was typing in an instant message in the 3D grid "Second Life," when my keyboard suddenly just stopped working. My computer started making the default "you just unplugged something" noise, followed by the "you just plugged something in" noise. It did this several times in a row, giving me a little pop-up that Windows did not recognize the USB device.

I unplugged the keyboard and it all stopped. After a moment, the keyboard worked fine again, for a few minutes, then repeated the problem. However, unplugging and re-plugging the keyboard back into the computer, both in the same and in different USB ports, have all yielded the same results - it works fine for a little while, then randomly stops being able to recognize the keyboard.

I tried updating the driver for the keyboard, but it did not come with a install CD, and when I tell it to automatically search online, it simply sits there for an hour with no results. In the course of posting this problem to this forum, the problem has occurred twice.

I hope someone can enlighten me as to why this is happening, and how to fix it. Thank you for taking the time to read this post, and I look forward to any feedback anyone can give.

Hello all,
I purchased an HP Pavilion 7966 1.7GHz P4 in 2001 from Best Buy. It has an 80GB Seagate ST380020A drive in it that over time got very noisy (making whiny, screeching noises) and so I purchased Gibson Spinrite and ran it on the drive. Spinrite found tonnes of bad sectors, and each time I ran it (I ran it 2 or 3 times) it found even more. The drive continued to get even noisier and Spinrite said it was dangerously overheated. I don't have any extra hardware in the machine, so the airflow should be as good as it was when purchased. Well, I went into Best Buy and asked if my drive could be replaced under Seagate's three-year warranty. BB said that because I didn't purchase the drive OEM directly from Seagate, it was only covered by BB's $300 three-year warranty (which I didn't purchase). So I swallowed the loss and purchased a Western Digital Caviar 120GB drive from ZipZoomFly.
I have Norton Ghost and Ghostcast Server at work, so I took my machine to work with the purpose of imaging the 80GB and then putting the 120GB in and dumping the image back down. Well, suddenly the Pavilion no longer recognises the Seagate: it says 'hard drive not found' when I boot it up. Is that drive totally toast?
(And yes, I make regular backups every few months but still want to get what's on the drive.)

A:Seagate ST380020A suddenly not recognised

Well sorry to say but it's not looking good for you with that drive. I bought a Seagate 200gb drive today ($75 after rebate + 5 year warranty = good deal) and hope mine will turn out better than your experience. Unplug the IDE cable from the Seagate drive and then plug it right back in. Turn on the computer and see if that helps. Sometimes little things like that can do it. Also, I have a friend that one time had a dying hard drive and he stuck the drive in his refrigerator for about half an hour and let it get really cool...he was able to get his data off of it after that. I know it sounds crazy, but when you have nothing to lose, you may as well try it out.

I've been using my laptop, outputting to my TV via HDMI for Months with no difficulty. Usually, the displays are duplicated as I have resolution issues if I output to just the TV ('show only on 2').

Yesterday, I changed the output to 'show only on 2'. Sure enough, it worked fine, my laptop display turned off, but the resolution was way too high, so I reverted back to 'Duplicate my displays'. The image on the TV stopped and it dropped to a 'no signal' screen, my built-in display was (and remains) fine. It now refuses to detect the HDMI output. The TV does recognise there is a device plugged into the HDMI port, but says 'no signal'. I've tried two HDMI leads, both same result (and both work fine on two other devices into the same TV using various inputs). My laptop just point blank refuses to see the TV. I've tried the Win+P thing, I've rolled back drivers, reinstalled drivers. I can't understand why this has happened and how to fix it, and it's important I am able to use my television as a display.

I really hope someone can help. Googling has brought up kind of similar issues, but not exactly this issue.

Thank you.

Hello. About a week ago my Western Digital 500gb external hard drive stopped being recognised by my PC. When I connect it up to the USB port the green light and everything comes on and it makes all the right sounds but the USB port just won't pick up that theres anything connected. I've tried other USB ports which won't pick it up either. I've tried other peripherals in the ports which work fine. My normal way of dealing with this would probably be to order a new hard drive except for the fact that this particular hard drive contains all my work projects which is typical! I've removed the hard drive from its casing and tried plugging it into my PC as an internal drive which resulted in my PC freezing and then me having to run the windows repair tool off the installation disk... I'm pretty sure I'm doing something wrong here and would just like some advice so I can put things right.

Many thanks,

Hi all. I am having issues with my NVIDIA GeForce GTX750. I discovered today that when I try to play a game, it's suddenly extremely slow and jerky. This issue has come a bit out of nowhere, as it was working fine when I last played a game (the same game) a couple of weeks ago.

The only unusual thing I've done recently with this desktop computer has been to move it interstate. That was about two weeks ago, and I haven't noticed any issues with any facet of the computer until today when I went to play at game on Steam for the first time since I moved.


Inter(R) Core(TM i7-4790) CPU @ 3.60GHz
64-bit operating system, x64-based processor
Windows 10 Home

Additional Notes

- I attempted to access the NVIDIA control panel but it won't let me, saying: "You are not currently using a display attached to a NVIDIA GPU"
- The GTX750 is still recognised by my device manager though
- My computer's not in power saver mode, which was my first thought
- My latest GeForce driver is up to date; is there any other drivers I should be chasing down?

I'm pretty hopeless tech wise so please bear with me and let me know if I haven't provided the correct/enough info. Thanks!

I have been searching for a solution

My R700 on Win7 was working flawlessly using the finger print scanner. At some point without any reason the
hardware (finger print reader to login) was not recognized by the OS anymore.

- I tried to remove the driver software, reinstalled it
- updated it and so on resulting that the hardware was not found.
- I even removed all relevant entries from the registry - no go.

- the Authentic Finger Print software starts up, but only giving an error that the FP-reader is not present.

Is there a way to remove the stored fingerprint manually by deleting the manually.

The hardware is working according to the support. (Machine was send in)
However I do not wish to re-setup the entire machine (it is a business notebook) just to get this to work?

Any hints or step by step intro to achieve this?

I could not find a descritpion on how to remove fingerprints (cause I suspect that is the problem) manually since the software to do this does not start up.

Any input would be appreciated.

Best regards

A:Portege R700 Finger Print Reader suddenly not recognised from OS

If you don't see the fingerprint hardware or unresolved devices in Device Manager then the device is either disabled in the BIOS or the fingerprint sensor is faulty or loose, or there was a liquid spill causing corrosion.

Been having lots of hassle.

Finally got mobo to recognise my soundcard - Audigy 2ZS. Now comp is quite unstable. Keeps crashing of own accord. Sometimes rebooting, other times to completely unresponsive state with display frozen, sometimes to blackscreen and have to hold on button in till machine shuts off.

When I restart I have lost sound. Card not listed in device manager. Computer still crashing randomly.

If I leave the computer turned off for a good couple of hours, sometimes when I restart the sound has returned and card is recognised in devices.

Anybody know what might be happening.

Also, my mouse pointer is jumping all over the screen of it's own accord which is very frustrating. Cordless Optical Mouse, reciever about 5inches away from mouse, latest logitech drivers, worse with SP2, enhanced pointer precission switched off. Mouse mat makes no difference.

Any suggestion on rectifying this prob or is it related to comp crashing ???

A:Soundcard recognised. Crash. Soundcard not recognised. Wait 2Hr Recognised Again ??.


You didnít mention if your sound card is built into the motherboard or is an add-on card. I'll assume itís an add-on. I would check to make sure the sound card is seated firmly in the slot, or another option would be to try another slot. Perhaps the one you have the sound card in is bad. Also, you may want to uninstall the driver for the sound card and download a new one from the manufactureís website.

You also mention that your mouse pointer jumps all over the screen. Usually when this happens to me, it means the battery's are starting to run out and need replaced. Also, try moving the receiver as far away from the monitor, speakers and tower. Interference from any of these devices can play havoc with the signal.

Good Luck.

I usually like to leave my computer on overnight. So I go offline, disable my wireless, and put on a video playlist in full screen to help me sleep. Anyway, today I woke up and saw the Windows Media Player no longer full screen, and the wireless switch was actually turned on. This is strange because I know I turned wireless off and I frequently check my system with Malwarebytes.

What could this be? Did someone snoop in my computer? Thanks in advance for the support.

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.

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

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:T440s - LG or AUO Display

Don't sweat it. Both are absolutey huge upgrades over the TN panel. While the AUO is a bit better, its not worth the trouble. I have both and I like both. I did a compare on the same thread u heard about the issue.

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.

Hello, and thank you for reading this.
As of just today, for some weird reason, my computer has just started to hiccup and freeze out of nowhere, and it's more prominent with any program that uses the internet (i.e. Firefox, Steam, etc), but it freezes up the entire computer along with the program. 
This is especially aggravating as just yesterday, my computer was working absolutely fine with no hitches or sudden slow downs, but by today, it just starts to act this way, despite me doing anything to the computer at the time.  I have also ran a complete virus scan twice to no avail, and I tried using System Restore, only for it to fail.

A:Lenovo t440s with 16gb ram?

Welcome to the forum!
The 4GB slot is soldered to the motherboard, so you have only one slot free, meaning max RAM stays on 12GB (4GB soldered + 8GB in the free slot).

I have a T440S that is still under warantty. The screen has a bright white spot about the size of a small led. It can be easly seen on a white bachground from several feet away. On a colored screen it appears as a spot of lighten color. It can not  be seen on a black background. I do not believe that this is a dead pixel. Is this covered by the Lenovo warantty? If not, how easy is it to replace the screen. Are screen whitelisted in the Bios? Can I upgrade this to a touch screen? The current screen is a AU OPTRONICS B140HAN01.2 Can I use any version of B140HAN01 or does it have to be the .2 version? I assume that the 2 refers to the version number.

A:T440s shuts down when i undock

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.
