Lenovo T420 Camera not found Windows 10 Upgrade

Q: Lenovo T420 Camera not found Windows 10 Upgrade

Dear Community, a friend of mine has a problem. He upgraded the Laptop to Windows 10 for about 6 months ago. His Webcam is not found. There is no Imaging Device in the Device Manager and there is also no "Unknown Device" in it. The Driver for integrated Camera from lenovo site did not help. I used the Forum search but the entries did not help either. Anyone knows a solution? Greetings from Germany

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.)

The free upgrade to win 10 pro failed several times.  I checked the web for problems and as a result uninstalled malwarebytes, antivirus, some drivers and some Lenovo stuff that popped up.  Finally the upgrade using the Media tool was successful.  Win 10 pro is now working on the T420.  However, only the Lenovo Companion is installed.  I bought a Yoga with Win10 pro and it came with Lenovo Companion, Settings and Account.  I have been trying to find a way on the Lenovo site to download the Settings and Account programs, but no luck.  Any suggestions?  (Probably a simple solution and I am just missing something obvious....)

Hi there. I am having trouble finding the camera on my 910. I tried doing a factory reset on the computer, but it couldn't find the driver. I tried going to lenovo's website and manually installing it, but still nothing. The last thing I have resorted to is to install legacy hardware, but I'm not sure which device I should install. I appreciate any advice! Also, an important note is that I cracked the screen on it a while back and had Geek Squad replace it using the accident replacement plan they offer. I am unsure whether the camera was incorporated before then, as I never needed to use it until recently.

Did some of you tried installing Win 10 on the T420 series?  PLease let me know, much appreciated. Chris

A:T420 and Windows 10 upgrade

The T420 isn't officially supported by Lenovo for Windows 10. It should still install and run fine, but you'll need to source your own Windows 10 compatible drivers from OEM sites.There are also driver aggregator sites out there like station-drivers (French, but the download button is obvious).

On My T420 I have just upgraded from Windows 1611 (Anniversary Upgrade) to 1703 (Creators Upgrade). As a result Device Manager reports a conflict in a basic system install stating no driver is installed for VEN 1180 - DEV E822. This is the Ricoh Multicard reader.Under Windows 10 1611 it had worked without problems. It works fine under Ubuntu 16.04 (has dual boot system).I have tried installing the latest driver version 2.22.18.01 released 8.6.2015 stated to be for Windows 10 and although no conflict occurs during the install, following a reboot it still shown as missing under Device Manager.The T420 is not listed under Lenovo's list of tested devices for Windows 10 1703.Has anyone else had any expereince or knowledge on what can be tried?Maybe I will just try the Windows 8 driver (version 2.22.18) from the Windows 10 driver was produced from.

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?

Also there are a few different types...

PSREF says the T420 uses "PC3-10600 1333MHz DDR3." You can use faster memory like PC3-12800 but it won't have any effect on performance.
 
I would buy a single 4GB SODIMM to add to your existing module. A matched pair will theoretically perform faster but the difference is single digit percentage. You won't be able to perceive it in practice.
 
As for voltage, I'd Google the part number of the SODIMM you now have then buy a second SODIMM that's rated for the same voltage.

Lenovo T420, Type 4177-CTO. Windows 7 Pro, 64 bit.  8 GB RAM,  500 GB HD, third party 128 GB SSD added. After inspecting many laptops I chose the ThinkPad T420. The only better laptop was Apple and I needed different software. An important consideration for any computer is support. Lenovo has excellent support at 1-800-426-7378. Tech support and repair happens right here in the United States.  Repairs are done in Tennessee. The Lenovo ThinkPad T420 is a solid laptop. It is not as light as some laptops but strength and durability need to be considered. Weight of machine with a large 6 cell battery and a slice battery = 6 lb. 7 oz. (3060 kg). The laptop weighs 5 lb. 5 oz. (2430 kg) with just the large 6 cell battery. The 6 cell battery weighs 1 lb. 1.5 oz. (500kg) and the 6 cell battery would then weigh 1/3 less. You can compute the difference. Keep in mind my battery life with the slice battery installed is about 17 hours. The slice battery also places the laptop on a slight angle with the rear elevated. It is about the same tilt as with the docking station. You cannot have the slice battery installed while the laptop in in the docking station. The 6 cell battery sticks out the back so it is not a perfect cosmetic fit. The 4 cell battery will look nicer, be lighter and probably last about 4 hours. The overall design is perfect in my opinion. I find no problems.

Hi I am new to this community, so I would like to applogise if I mist a simillar subject (I did check some but non resolved my problem). I have a thinkpad t420, I bought a used one. It worked great, and I bought it from a friend, that I trust. I installed a ssd drive, was usnig Linux, and everything worked for one month. But then I bought a HDD caddy, and replaced the CD rom. After that my thinkpad worked for a day (although it didnt recognize the second HDD). The next day I tried searching BIOS for some settings, and after restarting my laptop it was stuck on Lenovo splash screen, rebooting in a loop. I tried:- removing and replacing the caddy with the CD rom,- replacing my SSD drive,- replacing RAM (both slots),- reseting BIOS,- running a diagnostic CD (but it will not boot, neither can I boot from an USB) My google search showed that it could bi a problem with one of the USB pins inside of one of the ports (short circuit or something like that), but I could not finde any damage. So I am thinkig that the motherboard could be damaged, but I can access BIOS, but that is the only thing I can do with it. I would be wery thenkful for any advice or help, before I go to an official Lenovo service for help.

A:T420 stuck on Lenovo splash screen

Hi Zjaz123456,
 
Welcome to Lenovo Community!
 
As per the query we understood that you are facing issue with not booting to OS on your ThinkPad T420.
Is both HDD &SSD detecting in BIOS?
 
Check with removing CMOS battery, make sure you have disconnected the system from AC adapter and battery is removed.
 
Remove both the drive & battery from the system, disconnect the power adapter. Press and hold the power button for 15 to 20 sec perform this step for 2 to 3 times and then connect only the drive which is having OS installed in it. Use only power adapter to switch ON the system.
 
Hope this helps. Do post us back for further assistance!
 
Best regards,
Hemanth Kumar

Hi Lenoovoo,
 
Welcome to the Community Forums.
 
I would rather that you remove the battery and take it to a service center for general cleaning informing them of the immediate concern about the water spill. Do not attempt to power it on as tools may be needed to safely dry it up internally avoiding other issues.

If you have such skill and tools then you can use the hardware manual here a reference guide.
 
Hope this help answer your query.

Hello, I've owned this Lenovo T420 for 8+ months. I have been receiving random BSODs monthly, starting a couple months back, before then, I dont remember having them ever. More recently it has become weekly. Some days there is more than one. Today I've had 6. A couple of them occurred randomly just browsing on Chrome. Twice after I was connected remotely to a clients VM software. Then a couple times just booting up.

Currently I am connected to another client via RDP, browsing, and haven't had any issues for past hour.

I've ran the dm logger tool instructions and am attaching zip to this thread.

The only virus scanner I use is malwarebytes free and don't have any active ones. I've disabled windows updates because I've had issues with them in the past on this laptop.

Thank you,

Scott

Hi Daimyo21,

Welcome to the 7forums

If you have only Malwarebytes as protection, please install Microsoft Security Essentials
The software from Malwarebytes is NO Anti-Virus program and is not meant to run single on a system as AV.

Please install all updates from Windows Update available and check Lenovo for BIOS updates.

Hello!I just bought a Lenovo T420 without a WIFI -Card, Is there any way to remove this so i can use a 6235 Intel card instead of the 6205 which was in it originally?

Welcome to the Lenovo Community!
 
Actually, it's not a blacklist, but a whitelist.Anyway, I suggest flashing this modified BIOS version: https://www.sendspace.com/file/0whb9r
 
In addition to the removed whitelist, it has several other advantages over the original BIOS.

I have a Lenovo G50-70 with Windows 10 Home (version 1703, Build SO 15063.413), 64 bit operating system. The built-in camera doesn't work and so the built-in microphone (I'm not able to record anythin and I can't use any videonferencing software and neither talk with anyone). When I was on Windows 8.1 thse devices were working normally. Is there any solution (e.g. an external webcam or an external microphone) that can solve this issue or I ahve to downgrade to Windows 8.1 ? Thanks in advance for any help. Michele
