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.)

I upgraded to Win 10 via Windows update.  All went well, everything worked fine, but I did later find out that Lenovo isn't supporting T420 with driver updates for Win 10.  While Windows 10 was still installed, I looked at the driver support page for the T420, Win 10 is not listed as an option in the drop down of OSs.  Accepting this, and not wanting to run into problems later down the road with future Win 10 updates, I rolled back to Win 7Pro.  Now I don't think I have a straight answer on whether the T420 actually is supported under Win 10 or not.  The first thing I did after rolling back was to go to the Lenovo driver support page.  Now it shows windows 10 in the drop down as a supported OS.  What's up with that?  I've looked in the forums and elswhere online and every indication is that the T320 is not officually supported.  Lenovo does not list it as supported.  But yet now Windows 10 drivers are listed for the T420, but only when I'm running Windows 7Pro, not when I'm running Windows 10.  I'm assuming that the website is autodetecting my current OS.  I can't make heads or tails of it.  I'd like to go back to Windows 10, but given the confilcing info from Lenovo...Anyone have any suggestions.

A:ThinkPad T420 and Windows 10 support

While there are some Windows 10 drivers available now for your T420, many are still missing, so I would wait until it is listed as upgradeable by Lenovo, and thus all the needed drivers are released, or risk having issues.   Until then, I would stick to 7pro...  Lenovo supported systems list for Windows 10 Upgrade (Last Updated :01 Apr 2016)https://support.lenovo.com/us/en/documents/ht103535#thinkpad Lenovo Windows 10 devices tested for November Update / Version 1511 (Last Updated :01 Apr 2016)https://support.lenovo.com/us/en/documents/ht104857#tp

T420, upgraded to Windows 10 Pro via a clean install ... Works great ... had to find Conexant audio drivers so the audio would work while in the docking station ... Only remaining issues are that: a)The Bluetooth light below the LCD is always on, even when I've turned off the Bluetooth interface in the W10 settings. b)The special Thinkpad key combinations (like FN+F5 to turn the wireless off or on) don't work. Any suggestions about what software or driver installs to try?

A:T420 Windows 10 Bluetooth Light Stuck On, Thinkpad...

You can use the following utility to control the bluetooth light on T420 (and other Thinkpads): Thinkpad Fan Control (TFC)http://www.tpfancontrol.com Disable the light via the context menu of the symbol. The bluetooth control via Windows system tray is deactivated after installing TFC. Obviously, this utility is normally used for other purposes... Thorsten

A:Where can I find Bluetooth Peripheral Device driver for T420 Thinkpad Windows 7 64bit

Hi Forgany,
 
Welcome to Lenovo Community!
 
What you can do is uninstall all the Bluetooth application and drivers which you have installed currently and then download and install ThinkVantage system update utility. After the installation restart the system and run the application, this will search for the entire required latest driver for your system.
 
Hope this helps.
 
Best regards,

Tried troubleshooting with drivers and eventually did a hard reset which did address the issue...only temporarily. I already looked into other forum post regarding deleting and reinstalling the fingerprint drivers as well as the Intel SGX drivers as well but those didn't seem to solve the issue. Any insight on the issue would be great!

Hello,Today I updated my Thinkpad X1 Carbon 5th Gen with the latest drivers recommended by Lenovo Vantage program, as well as the latest Windows 10 Pro updates. After conducting those updates, I can no longer sign in using the Fingerprint sensor.When I open the Device Manager to check the status of the Biometric Device driver, it shows the following message: "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)"The sign in option using the fingerprint does not even show up in the Windows settings for Sign In. Things I have already tried:1) Update the driver through the Device Manager 2) Download and reinstall the fingerpring driver from the Lenovo drivers website3) Reset fingerprint settings in the BIOS and making sure it is enabled4) Change configuration in "gpedit.msc" -> computer configuration -> administrative templates -> windows components -> biometrics -> allow the use of biometrics and allow users to log on using biometrics set to enabled None of the 4 attempts above solved the problem.Can anyone please provide any solution for this case? It looks like a lot of people have been experiencing this issue and no one from Lenovo provided a clear and definitive solution. The latest drivers must have bugs and, in my opinion, Lenovo must stop distributing them until this issue is fixed. Thank you very much.Best.

Hy!I've used my Thinkpad T420 battery charge mode with custom settings: Start charging when below 95% and Stop charging at 99%. Because the battery effectively has never charged full, it cause sudden capacity decreases (for example from 30% discharging to 7%). I got bored to this and changed to automatically optimize battery lifespan. I noticed that every full charge the "Full charge capacity" value decreases. I have charged it 5 times after this settings, and the remaining capacity looks like this: 57.10Wh, 57.05Wh, 57.00Wh, 56.95Wh, 56.85Wh.

Hello, all.My T420 audio system has worked perfectly for years. But, starting in January 2018 the microphone mutes itself, no matter what I do with its settings. Sometimes the muting happens in a few seconds, sometimes after a few minutes. I can watch it happen in the microphone levels window. I suspect a Windows update or new version of Skype caused the problem. I have been unable to fic it. Neither Malwarebytes nor any Windows security scanning software see any issues. This is especially aggravating since I'm a software engineer used to fixing bugs. (Yes, I've watched the YouTube videos about this problem, to no avail.) Anybody have a fix for this?Cheers,Dave

My laptop LCD has been out for awhile and I've been using with an external monitor, but I decided to fix the LCD so I ordered a new LCD screen for it. The lcd screen arrives, install it and picture still doesn't show up. I then thought maybe I just had a bad cable from motherboard to LCD so I replaced that.. still no luck.

I can see a faint image in the background, but it's very dark. Same with my original screen.

What's odd is before my original laptop would show a just scrambled picture of black and white-- which is why I originally thought it was LCD.

What would the next step be? To order a inverter? Do the symptoms above sound like it's a bad inverter?

Hello, thanks for taking the time to read my thread. I'm a long time IBM/Lenovo user, I've recently purchased a thinkpad t420, which came with 4gb of RAM. My initial plan was to upgrade it to 8gb of RAM as that's what crucial said was the max it could handle.

Can someone tell me what the issue is? Did I buy the wrong RAM, or is the RAM I purchased not working? Any assistance is appreciated.

I just bought a refurbished ThinkPad T420. A friend of mine said it had a good spec so I was looking forward to having a play around. Right from the minute I switched it on there was a problem. The touchpad and mouse are not working. The only way to use the mouse is via the track point (is that the right term?) and I hate it! It's way too fiddly. So I tried fn and F8... it doesn't work. I've tried rebooting and enabling the touchpad in the BIOS it doesn't work. I've deleted drivers. Still nothing. I've installed new drivers. Many tutorials say you can fix it using device manager, mouse etc. But the tab the recommend you choose is not there. I installed new drivers from synaptics and it says there is no synsptics device found. I am honestly going insane! Something that should be so simple and it's so awkward! Forgive me because I'm half asleep but I should mention when I first tried to fix it the tab in mouse properties that everyone says I should use (ultra something) well it was there. But when I tried to click any of the options on that tab I was kicked out and got an error messsge. Now that tab no longer appears. It's running on windows 10. I'm ready for launching it out the window. Help!

Something absolubtely bizarre is happening with my mouse, and despite my efforts, I can't find any posts on google that match my issue.

About a month ago I spilled some coffee on my laptop. The laptop's built in mouse buttons stopped working shortly afterwards. I took my computer into the repair shop and had them install a brand new touchpad and mouse button set. Everything worked fine up until a couple of days ago.

First, my left click stopped working (on the laptop track pad). The next day, the right click stopped working. I could still left click using the touch pad and right click via Shift + F10. The following day I could no longer left click using the touchpad. I brought home a USB mouse today and plugged it in. The USB mouse worked great for a couple of hours, and then started failing. It will select some objects, and not others. It will left click for a few minutes, and then stop working all together. It will allow me to open new tabs in a brower, but not select other open tabs or the bar where you enter web addresses. It won't select anything off the task bar, including the windows start menu.

So far, I have uninstalled the computer's mouse drivers and re-installed them. I've rebooted several times. I've tried turning on the functionality that allows you to use your keyboard as a mouse, but that didn't work. I've tried different USB ports for the external mouse.

Hello,The Bluetooth indicator light on my Thinkpad T420 is stuck in the on position regardless of if I have bluetooth on or off. This was never an issue until I recently installed a fresh version of Windows 10 on a new SSD. I just want to know how to either:1. fix this problem so that the light works as it is supposed to function, OR 2. disable the Bluetooth indicator entirely so that it doesn't remain on forever. Thanks so much for your help.
