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 am a bit befuddled with the T420 for a few reasons, but primarily while trying to dual screen I keep hitting one problem or another. First Specs, Basic Enterprise T420 i7-2720m, 8Gbs 1333 RAM, Integrated HD 3000, with CD/DVD RW, It has the 1600x900 Built in LCD, and is equiped with a smartcard reader and modem card. Now that thats out of the way, I cannot get dual screens for the life of me with this laptop. Now I dont have any monitors with Display ports so Im still utilizing DVI, and VGA, and one HDMI port, and I have a display to HDMI adapter lyin around. I tried using the adapter with my monitor, and TV, but with no success. Next I went well, Ill get a docking station, it has a VGA and DVI connector, so I did, but the VGA port outputs red only, no blue, no green, whilst the DVI works fine and best thing is I cant return it. So I grabbed the Display to HDMI, and tried the docking station Display, with the same results. Even when its the only attached monitor it doesnt see it. I tried Win10 Display Settings, Enabling and disabling the "Digital Display" in the Intel Graphics options, and tried the Fn+ F5 or whatever thats suppose to out put to the external monitors, all with no luck. I see people here saying to change BIOs Video options, but since I dont have nVidia, all I got is Defualt Boot Screen selection, i.e. Built in Display, Analogue, Digital Disp. 1, Digital Disp 2 <--When I select either of those it still outputs on DVI.

Hi all,I have a T420 and minidock series 3 (4337), and recently upgraded to a BenQ BL3200 monitor.  The only way to get 2560x1440 to the monitor at 60Hz on this machine is DisplayPort. Plugging directly into the DisplayPort on the laptop works fine, but plugging into the DisplayPort on the dock causes the monitor to turn off (no signal).  If I have my laptop screen up, even it goes black when plugging into the dock's DisplayPort. I borrowed my sister's identical dock to rule out a hardware issue with the dock itself, and same behavior there.  I'm wondering if this is a driver issue?  I tried a few of the newer versions of the Intel HD3000 drivers and no luck.   I'm running WIndows 10, fresh install.   I do not have the Nvidia discreet chipset, just hte HD3000 onboard graphics.Thanks! 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?

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. The T420 uses the LED night light that shines from the top of the display to ... Read more

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.

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,

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

I have a P50 with Windows 10 1607 LTSB installed using an ultradock and 2 2560x1440 BENQ monitors connected via Display Port.Weirdly the monitors keep coming back at a low resolution after the computer goes to screensaver or power save. The resolutions available change in both the nVidia and Windows control panel, neither will have the correct recommended resolution - they often max out at FHD 1920x1080. Sometimes they only go to 800x600. Powering the monitors off and on seemed to fix the display visually, though Win10 and the nVidia panel only show an incorrect lower resolution. Lenovo System Update doesn't show any graphics drivers updates... This is pretty new to us, I don't think we've seen this with Windows 7 SP1 x64. Any ideas?

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....

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.

Where can I get cables and adapters for the Dual-mode DisplayPort (DisplayPort++) output port.  I want to connect multiple monitors to my laptop for use at home, without buying a docking station.  I already have an old VGA monitor connected to the VGA output.  Are there any other options for connecting additional monitors other than the DisplayPort++ output and docking station?  I've searched Amazon, E-Bay, Best Buy, and nobody seems to have any cables or adaptors that support DisplayPort++.

I recently bought an HP Envy 32 monitor and hooked it up to my Mac mini using a mini DisplayPort (i.e. Thunderbolt) to DisplayPort cable. The video works fine @ 2560x1440, but I have no sound. The sound output in system preferences mentions "The selected device has no output controls" for the Envy 32. The sound works fine when I use an HDMI cable, but then the resolution is limited to 1080p. The Mac mini is a mid 2011 model, which is capable of transferring audio via DisplayPort, as far aas I know. Any suggestion on how to solve this?

Figured out how to get mini-displayport audio to work with the HP monitor (I have a Macbook Air)In addition to selecting the HP Monitor as the audio output in SYSTEM PREFERENCES--->SOUND-->OUTPUT-->HP ENVY 32 An adjustment also needs to be made to the AUDIO MIDI SETUP.  you can either do a search for it in the finder, or it is in APPLICATIONS -->UTILITIES-->Audio MIDI SetupOpen the AppSelect DisplayPort in the left menuUnder format...change to 48000.0Hz  2ch-24bit integerOnce changed you should be hearing audio from your monitor.Good luck.

Are there any adapters to do this or ways to do this? I can't seem to find any.

I am buying new monitors, the dell u2414h. Now, while this does have hdmi, I will be connecting multiple monitors together to extend the display from the laptop to give me multiple screens. The problem with this is that it only works if you use displayport and not hdmi, so I need a way to convert the hdmi to displayport or mini displayport.

I will primarily be using these monitors with my laptop that has displayport, so that is why I am getting these monitors and that won't be a problem. I will most likely hook up other laptops to the monitors and hdmi is way more common from what I have seen on laptops than displayport and is why I need a way to go from hdmi to displayport or mini displayport.

Any ideas? Thanks.
 

A:Hdmi to Displayport/Mini Displayport

You can't, HDMI does not support daisy chaining in the manner that DisplayPort does and you can't use a simply adapter to go from HDMI to DisplayPort and get the features of DisplayPort.

Hi all, I got today Lenovo S510 model: 10KW005NAX I want to get a cable or adapter to connect Displayport to HDMI 1080p LCD I have from before There seem to be passive and active converters, what I understood from online is that if I have DP++ PC I can get a passive converter or else I need an active converter. I don't know if cables can be active and passive too?For example: Amazon linkSo the description says source can be DP or DP++, so it has a chip inside it? so it's active? So... can anyone tell me what is my displayport type (Lenovo S510) ? and maybe shed some light on what I need to get clear picture to HDMI in? Appreciate your help

Since you have to hunt around different Lenovo sites (and other sites) to find out about these softwares, I decided to make a post to get feedback from actual Yoga owners on how these programs interact, what they do, which ones are prerequisite, and which ones are unnecessary. Please don't take this as a blanket answer. This is just what I have found. It might be right - it might be wrong. I'm looking for others to post their experiences as well. Lenovo System Interface Foundation Driver - Necessary prerequisite (missing driver in device manager without it). It allows the Lenovo Utility and Lenovo Companion to work. Lenovo Yoga Mode Control - Necessary if you want to use your yoga to seemlessly change between all the different modes (laptop, tablet, tent, stand). This software is responsible for autorotating and putting Windows into tablet mode. Lenovo Utility - Recommended(?) This one I'm not too sure on. I remember that I was missing some function that I wanted but I can't remember what it was now. Maybe battery cycle count and health? Lenovo Companion - I don't have this one installed and don't think it's necessary but would like someone else to shed some light here.
