If you use a Lenovo laptop computer, then you’re already probably familiar with the Lenovo Service Bridge and some of the issues that come along with it.
While errors involving the Lenovo Bridge aren’t severe and don’t cause that much damage, they can be slightly disruptive of your computer use.
At times, it can even be a virus in disguise as a legit program. In any case, we’ll discuss a few ways to fix these related errors in the event that you come across them.
What Is the Lenovo Service Bridge?
First off, let’s determine what the Lenovo Service Bridge (otherwise known as the Lenovo Bridge or LSB.exe) is.
According to Lenovo support,
“Lenovo Service Bridge is a Windows program offering several support related enhancements to make the site navigation easier for end users. The current set of capabilities include the following features:
Automatically detect your machine’s serial number and machine type – model. This information is then passed to our website so that we can better assist you with your support needs. This replaces the need to search or browse for your product when you need support.
Download multiple files at once from the product downloads section with pause, suspend and resume.”
It is an executable file that was created by Lenovo so that the user of the Lenovo user can have an easier time getting the needed help from their eSupport team.
What it does is it stores the computer’s serial number and model number and provides them to the Lenovo help support site automatically.
From there, the Lenovo help support team can easily identify the problem with your computer.
There are two issues that you may get with regard to the LSB.exe. The first one would be the error message known as “Failed to listen ports: 50128, 50129, 50130”.
The second would be if the LSB.exe file is a virus.
How To Install It
In this video, Lenovo shows how to install Lenovo Service Bridge in order for the Lenovo Support website to automatically determine the serial number and machine type of your Lenovo computer system.
4 Fixes For Lenovo Service Bridge Issues
1st Fix (Remove Or Delete)
According to ShouldIRemoveIt.com, the first thing that you should try is to remove or delete the Lenovo Service Bridge.
When you remove it from your computer, you should be able to fix the problem related to the LSB executable files. You can do it by following these few steps:
- Go to the Start Menu then to the Control Panel.
- Look for Programs or Add/Remove Programs or Uninstall Programs.
- Look for the Lenovo Service Bridge and click the Uninstall button.
- Wait for the program to uninstall.
After you do this, you should have no more problems with your LSB.exe. In this situation, you can now choose whether to download Lenovo Service Bridge it again or not.
All you have to do is go to the Lenovo website and download it.
2nd Fix (If It’s Not Starting)
If ever you reinstall the Lenovo Service Bridge and it doesn’t want to start up, then you might want to download the Lenovo System Update for Windows instead.
How To Use The Lenovo System Update
Most of the people in the Lenovo Community Forum agree with this suggestion.
This also works for Lenovo computers and pretty much has the same functions.
The first thing you have to do is uninstall the Lenovo Service Bridge (you can refer back to the 1st fix to know how to uninstall LSB.exe). After that, follow these steps:
- Go to the support page of the Lenovo website.
- Go to the Downloads section of the page and look for Lenovo System Update.
- After that, download the Lenovo System Update.
- Install it on your computer.
Since they pretty much work the same, then you should have no more error messages with regard to the Lenovo Service Bridge.
3rd Fix (Lenovo Companion Alternative)
If you’re using a Windows 10 OS and your LSB.exe doesn’t want to work, you can try to download the Lenovo Companion instead.
What Is It?
Again, this is a suggestion made by members of the Lenovo Community Forum.
It may not be as comprehensive as LSB, but it doesn’t depend on LSB and is the more upgraded version of the Lenovo System Update. To do this, follow these steps:
- Uninstall LSB by following the steps in the 1st fix.
- Go to the Lenovo website and look for Lenovo Companion in the downloads page.
- Download and install the Lenovo Companion
- Restart your computer.
When you turn on your computer again, you should have the problem already solved. Since the Lenovo Companion is built specifically for Windows 10 and above, it’ll work just fine.
4th Fix (Virus Issues)
According to some members from the Lenovo Community forum, there is a huge possibility that the LSB.exe may be a virus disguised as an executable file (usually this happens when the file is not genuine or original).
If you think this is the case, then follow these few steps:
- Do a full scan of your computer and check for any viruses.
- If LSB.exe appears in the list of viruses (usually as a Trojan), then quickly delete it.
- Go to Control Panel and to the Programs section.
- Check if the Lenovo Service Bridge is still there. If it is, uninstall it from your computer.
By doing this, you are quickly eliminating the virus threat in your computer. Now, if ever you do want to have Lenovo Service Bridge in your computer, you have the chance to reinstall it again by going to the download page in the Lenovo website to download it again.
Since you’ll be downloading a genuine copy, you shouldn’t have any more problems with it the second time.
