Uninstall Lenovo Service Bridge on my T420?

Q: Uninstall Lenovo Service Bridge on my T420?

For updating my T420 in Lenovo support website, I installed the Lenovo Service Bridge. However, my security software detected it as a malware and deleted some files. Then every time the laptop starts, there will be a couple of pop-up windows (see lingks below), which is the same when I click the service bridge installation file. So I doubt that the service bridge is running somehow at the backstage. http://i.imgur.com/EBHdq8c.jpg http://i.imgur.com/P7t33ax.jpg When I clicked the detail button, a log file came out.

Preferred Solution: Uninstall Lenovo Service Bridge on my T420?

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 spoke to tech support yesterday, 24 hours ago, Lenovo Service Bridge was down.  Seems it still is.I'm concerned as one MAJOR issue LENOVO has had is support for new products and downloads. Seems the proper updates just are not set up correctly with new laptops before they start distributing them.  My history with Lenovo Yoga was not good with no updates and it seems the bios was set with different serial number than the laptop and it identified the laptop as a Thinkpad instead of Ideapad so all the updates were messed up (the serial number had 0/o and l/1 that was done inacurately by Lenovo, it took tech support months to figure out what was wrong until they came to my house with parts that would no longer fit as the serial number match up caused all the issues.So just got the 920 and I know the bios needs updating and so do tons of the drivers. Wanted to go the easy way and use Lenovo Companion, that was a joke. Then let's go to website and get updates, none.  Ran the checkup and lo and behold 22 updates yet Lenovo Service Bridge fails to install a single one of them.24 HOURS is not acceptable to have this still not working!

When trying to reinstall Lenovo Service Bridge on my yoga 2 pro (80AY) running windows 10, I get an error message saying that LSB is already installed at its latest version, at which point the install program quits.  However,  I've uninstalled (or at least tried to uninstall) LSB, using the windows uninstaller & then susbequently deleting folders from the Program and Apps directories.  I've also "cleaned" the registry with iolo system mechanic.  LSB appears to be gone, except when I try to re-install it. Any suggestions as to how I can actually re-install LSB?  Thanks.   (Why am I trying to re-install LSB?  Because the machine is having "issues" with an Intel AC 7260 wifi modem, that lead it to lose network connnectivity -- the adapter cannot then be reset either directly or via the trouble shooter.  However, if I turn off the wifi from the taskbar, wait a couple minutes and then run the trouble shooter, it manages to fix the problem.  Maddening...  I'm hoping a clean install of LSB will take me closer to fixing this problem.)

PC / Windows 7:
1. Wondered why automatic "download update" or whatever they are messages seemed to be appearing rather frequently;
2. Asked on a couple of on-line forums; was told that ""Lenovo Service Bridge (LSB.exe) is a Windows program that will automatically detect your Lenovo computer's serial number, machine type and model. It then passes this information to our website so that we can better assist you with your support needs."
3. So? I do not have a "Lenovo computer"! Why is this program on my PC attempting to gather information to "better assist [me] with . . . support needs" I have not known I had??
4. So, since on-line info from different sources was inconclusive about whether the LSB.exe business was necessary, I uninstalled it and deleted any "Lenovo" listings found in regedit.

So I installed the LSB app and achieved the recognition of my Yoga 2 pro which lists 17 drivers that can be updated. Trouble is, when I select a driver and initiate the download, i'm left staring at a spinner indefinately. I tried on both Chrome and Edge but get the same results on both Browsers. Is there any other way to identify and download the correct drivers?

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 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

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 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,

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.

Did you ever find a solution to this?   Not a good sign that they're ignoring your question.

I just got a refurbished Lenovo PC-Thinkpad T420.  I think my 420 is stoned.  When I try to face chat (or whatever you call it) I can't hear them but they can hear me.  Where do I go on my device to check to see if something is wrong with receiving voice?

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 have had this problem with the laptop since i got it. Have tried updating all drivers and the system bios, which has seemed to reduce the frequency of the freeze and shutdown, and searched for solutions on the net but I seem to be going round in circles. Please assist me in finding out what the problem is and how i could fix it. I have attached the necessary files.

Your most recent .dmp files were from October. Make sure you have your system enabled for generating dump files. Dump Files - Configure Windows to Create on BSOD OPTION TWO part 2. will configure them properly. Also, avoid using any disk cleaning software (CCleaner, Windows Disk Cleanup, etc.) after a crash occurs.

Hello, I rescently bought a lenovo t420 from a vendor thats not lenovo. It was find for a while, but then it got a malware virus. i did a removal of the malware. I then powered it on again but it displayed the thinkpad logo and the next screen was just black with a blinking underscore in the corner. I downloaded a diagnostic program to a usb and ran it. This is what the log says-> http://paste.ubuntu.com/p/P8H5BrGqmc/ Any help would be appreciated.

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?

A:Lenovo T420 remove BLACKLIST WIFI CARD??

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.
