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.)

Hello, have you downloaded the DVD Multi Firmware Update Utility? https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-t-series-laptops/thinkpad-... This utility will examine your system configuration and detect all SATA optical
drive (ODD) installed in your ThinkPad.
SATA (Serial AT Attachment) is a new interface for storage devices.

The utility will then check the firmware revision of the ODD and judge whether
your system requires a firmware update or not. If required, it will prompt you
to run the appropriate firmware update program for your drive.

However, this T420 seems to have something else other than the 3.5mm combo socket in place, on the right corner panel, just before the CD tray.

Hey everyone, I've been to one end of the Internet and back looking for a solution on this. What I'm trying to do is get an AirCard that my client has working on their laptops (to phase out the use of USB modems which, unless you secure it to the lid of the laptop has a tendacy to break the USB ports on the laptops). Sierra's website is less than useless as it wants to direct you to the NetGear site, NetGear doesn't have this model on their Support Downloads section. I've tried every version of the drivers posted by Lenovo. The problem is, the drivers posted on the Lenovo Support section of the site for the Sierra Wireless MC8355 Gobi 3000 WWAN addon card aren't WHQL certified so they trigger contstantly the Driver Unsigned messages in Windows 7 64 Bit. I have tried turning off the driver signing enforcement but that's a no go. Message that's showing up is: A recently installed program tried to install an unsigned driver.

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?

Hi, I bought a Lenovo Thinkpad T420 from an online auction. It had no hard drive. So I went to the Microsoft Windows 7 download page and typed in the Windows Pro 7 COA and Microsoft responded with that is a pre-installation OS and I need to contact the manufacturer. I installed a new SSD and will need re-install the operating system. So where do I get an installation disk?

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

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. Thnak you! Z.

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.

I just purchased an adapter plug that allows me to connect my Lenovo/IBM thinkpad (T420) to my HDTV by plugging the HDMI cord into my TV and the other end to this adapter plug which converts the HDMI cable into a male plug which fits into my display port (there is no HDMI port on this model computer). It worked, but now I can't remove the adapter plug...it's stuck in the laptop display port. I do not know if the problem is caused by the male adapter plug or the female jack in the computer, but they're locked together now.

I have previously read review comments (on these HDMI/display port adapter plugs) mentioning this jamming happening on more than a couple occasions, but I don't recall any resolutions being mentioned except to break off (and destroy) the plug and possibly damage the display port as well. I called Lenovo tech support but they said I'd have to mail the computer to them to get it fixed. I'd prefer avoiding that if possible even though my warranty is still in effect and it would be of no cost to me.....just time lost without a computer.

I'd greatly appreciate hearing from anyone who may be aware of how to resolve this problem (and also how to avoid it happening again) without doing damage to either the plug or especially the computer display port.

Thanks for your consideration in any case....

My pc was running well and I decided to reinstall windows but this time I have problem...I have windows 10 and my laptop is Lenovo Thinkpad T420  My power plan minimum and maximum processor state are both set to 100% and for some reason i can't change them, they are like stuck to 100%. Even when I try to restore my settings to default the maximum and minumum processor state will still remain at 100%. I want to change my minimum processor state to 5% and maximum to 80%. I did it everytime after reinstalling windows and this time it just don't work. My laptop is overheating a lot while I'm playing games or just watching videos. I already tried to reinstall windows for one more time and first thing I did was changing maximum processor state in power options but it didn't let me type other number except 100%.  To be more clear what is my problem, here is recording of it: Please help, much appreciate, Thank You!

Have you tried to update the BIOS yet?  If not, that would be a good place to start.  You can also try pulling the battery out while having the laptop plugged in and see if you get the same results.  If so please let us know.

I just installed the office AMD VGA Driver jan 17 2017 16.40.2701.1. once through amds regular install and then a second time after using DDU in safe mode.  I can now access radeon addition settings display color setting all drivers since 16.9 drivers.  I use a tv as a display and need that function greatly.  I havent been able to get it to show that tab with AMDs newest drivers at all.  My new problem is with Lenovos drivers my apu is max 800mghz constantly when plugged in. I attached a pic so you can see.  The APU going from 800 to 300 was me plugging and unplugging it.  This is an issue for me now because I down clocked my CPU to play some games and now im crashing constantly from what my guess is the APU at 800 mghz constant even with little no no load.  THis is so frustrating Lenovo and AMD.  THis is the flagship laptop for AMD right now and Its terrible with drivers.  So any help or explanation would be greatly appreciated. I just want to use the newest drivers with display color settings.  Its not that hard to ask. EDIT in radeon additional settings I always have used maximum performance when plugged in and now when I switch it to optimize battery my APU for down to 300 when in idle or light load like it should and used to with all the other drivers ive used and left it on Maximum Performance.  This sucks if that settings on optimize battery the cpu runs at 2.5ghz on high performace. &...

Hi. I've got Lenovo G580 (20150) and I'm trying to install the geforce graphics card present in the system. I don't know exactly what the gpu model is but it's something akin to Geforce 610M. I've got Windows 8.1 installed and the drivers from Lenovo support page for this laptop don't work (I tried drivers for Win 8.1/8/7). During installation the drivers installer says that it "couldn't find appropriate hardware". I also tried various drivers from sites like driveridentifier but none worked. I even installed Win 10 and Windows Update found but couldn't install the drivers. I also have  Win 8.1 freshly installed. It's definitely not an OS problem. I also don't have recovery dvds/partition... Here are the graphics identifiers:PCI\VEN_10DE&DEV_1140&SUBSYS_397717AA&REV_A1PCI\VEN_10DE&DEV_1140&SUBSYS_397717AAPCI\VEN_10DE&DEV_1140&CC_030200PCI\VEN_10DE&DEV_1140&CC_0302

Should I be getting my drivers from Lenovo's site or Lenvo Vantange system? I always check Lenovo's site for new drivers because I never use Lenovo's vantage system but I have seen some people say that Lenovo Vantage system has newer drivers. Is that true?

Hey. If anyone has this laptop model, or rather 80g0017uua, please give me a link to all the drivers from the D (Lenovo) drive, since the official site does not have all the drivers. If it is not difficult, you can pour it on Google drive yourself.
