Lenovo T400 / T500 :: T440P - Screen Brightness Shortcuts On Keyboard Doesn't Work
Nov 25, 2014
The company I work for just gave me a new Thinkpad T440P and I have a screen Brightness problem. the shortcuts on the keyboard doesn't work with or without the fn button and the brightness gauge doesn't show up in the power options too.
Someone suggested to that I should download and install the latest Intel HD Graphics Driver for Windows 7 from the support page [URL] ... but after the installation ended a pop up on my screen said that my Laptop doesn't have the minimum requirements for this driver! so who come it's in the drivers section for this model?

My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.

I tried to do fn + f7 to toggle display modes as I want only laptop or monitor display, not both. But when I do fn + f7, the small window pop up ask me if I want to turn on caret browsing or not. How to toggle display modes between laptop or monitor for t440p, window 8.1?

my new T440p with built-in WWAN Ericsson N5321gw doesn't recognize the SIM-Card. I'm running Win7 64 Bit and in the device manager, I can see the Ericsson device showing up without any errors. Once I launche Access Connections, I receive the error message there's no SIM card inserted and I should insert the SIM and try again. The SIM is inserted as shown next to the slot (although I tried other ways, too). I tried two different SIM-cards just to be safe, both SIM-cards are working in my phone.

I recently purchased my new notebook (Lenovo T440p) which comes with OPTIMUS integrated Intel graphic card coupled by GeForce GT 730M 1GB. I tried to play some games; however for some reason in game options show, that my Intel HD card is being used as a default graphic card. This suggests that OPTIMUS technology is not switching the graphic card properly. System running on windows 8.1 Pro 64bit. How to enable Optimus switching?

This is a brand new TP T440p and I installed a fresh copy of Windows 8.1 Pro on it (licenced). I've applied all Windows updates and installed all drivers/BIOS updates from Lenovo System Update.
The computer works fine, but when I put it to sleep and wake it back up, the external monitor is almost always flickering (there is a 1mm movement to left and right, line by line - I'll shoot a video, if the camera will be able to capture the movement, because it's very "fine"). Sometimes it stops after a few minutes, but most of the time I need to re-boot the computer.
Also, not always, but many times the WiFi connection is lost and I can't reconnect unless I reboot the computer.

I have the T540p and the webcam doesn't work at all. When I try using it in Skype and Adobe Connect, I just get the camera icon with a slash through it. I've read in other forums that uninstalling the webcam driver and reinstalling it doens't work. I really need the webcam to work so this is pretty urgent for me.

Have been trying to upgrade my T410 running Win7 SP1 64bit from 2x2GB to 2x4GB RAM (KVR13S9S8/4, Kingston ValueRAM 4GB SO-DIMM, 204Pin, DDR3-1333MHz, 4GB, DDR-1333 (PC3-10600), CL9, 204-Pin) but Windows doesn't start with this memory.
The weird thing is that the PC boots and i can enter the BIOS and can see the 8GB installed, but Windows 7 hangs at the startup screen and never comes up. I first thought of defect in RAM and have requested replacement from vendor, but same issue with new RAM modules.

I updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.

I updated the BIOS of my TP T410 (2522), German keyboard, to 1.45. After the update both CTRL keys do not work any more. The same for AltGr. When I activate the FN CTRL switch in BIOS the FN key - as supposed - works like the CTRL key. But when I deactivate it again the FN gets back to its proper function and CTRL does not work.
When I connect an external keyboard via USB it works perfectly. How to get the CRTL key working again?

according to the lenovo US site every T440p will come with 4xUSB3 as standard:
[URL]
The psref´s (WE for western europe, but also the worldwide) say it will come with 2xUSB3 and 2xUSB2:
[URL]
All 440p you can order here in Germany unfortunately seem to have 2xUSB3 only.
This is very confusing. Why sould lenovo buy/develop a 2xUSB2 version (USB3 is fully downwards compatible) ?

I have bought new T440p (20AN006NUS). Everywhere was written that it comes with preinstalled Windows 7 pro and also includes Windows 8 pro license.
As I understand license key for Windows 8 is embeded in BIOS. But I have not any installation media for Windows 8 included in the box with laptop. How upgrade to Windows 8 should look like?

I can't adjust my screen brightness using the Power Manager. Updating to the latest release of the ThinkVantage Communications Utility did not solve the issue. I can't make the screen either brighter or dimmer.

How to reduce screen brightness below standard level in ThinkPad T520 ?
I think it is possible somehow, but I don't know how. I reduced brightness to zero using Fn key + End key, but it's not enough, I want to make screen darker, because my eyes get tired.

I just received three new T440p laptops using Win7 Pro. Unfortunately, the wireless link to keeps disconnecting ever so frequently on all the machines. I have updated the Wireless drivers, reinstalled the BIOS and even optimised power options to enhance the wireless perfomance but none have worked.

Just got a T440p and it's working fine. BUT when I go into an application like Word and either hit the function key or combine it with the Alt, Ctrl, or Shift key, I still get the default action of the Funciton key. For example, in Word, the Alt-F9 combination is used to display field codes. When I do that, however, I get the Control Panel popup. Similarly, in a browser, I should be able to hit the F12 key and get the Developers pane at the bottom of the screen. But instead in IE, Chrome, and Firefox, I get a My Computer popup.

I just got myself a thinpad T440p and was planning on getting a docking station. Since i have never gotten one before i was confused on which one should i get. I wanted to get the thinkpad Ultra Dock but was confused on how i would determine if i should be getting the 90W, 135W or the 170W. I live in Canada, Ontario if it makes a difference.
I was also curious, whats the main difference between the basic dock and ultra dock. Is it worth it for me to get the ultra for work?

IBM/Lenovo laptops and desktops for a long time. I recently purchased a T440P laptop with a standard 7200 RPM HDD in it. In the past, with previus models, when I wanted to troubleshoot the current Windows install (virus infections etc) I would use UBCD4WIN on a USB stick to boot the computer to USB and access the hard drive to pull data off or remove files infections etc. With this new T440P I cannot seem to see the hard drive when I boot it up with the USB stick.
I can boot the computer just fine and run the USB based OS without trouble but I simply cannot see the hard drive.
So far I have tried:
-Adjusting UEFI to Legacy and/or "Both"
-Adjusted CSM to Yes and No
-Disabled/Enabled Secure Boot
and several combinations of all of the above in hopes it was the issue but it doesn't seem to change my ability to see the hard drive. It simply doesn't show up.
The drive itself (in the T440P) is a standard HDD (not SSD) and is formatted NTFS with Windows 7 64bit installed on it.. The UBCD4WIN is a basic "Windows XP" x86 (32 bit) OS on a USB stick and the USB stick is formatted FAT32.
In previous lenovo models (T400/T410 etc) all I had to do was switch AHCI to Compatibility and I could see the drive but this one is giving me a real fit and I am not exactly sure if its a controller driver, UEFI or something else.
how to see the hard drive when booting to the USB UBCD4WIN stick?
