L540 BIOS won't update

2019-05-27, 14:33 PM

Cannot update L540 BIOS.  It currently on BIOS v1.82 and I have tried every newer BIOS version up to the latest version v.1.93 with both the Windows utility and boot CD methods with the exact same results with all of them the update utility starts reboots the system but never actualy runs the updat process with the section including the progress bars.  The funny thing is, each time the utility completes I check the log and it says the BIOS was updated successfully but the version never changes.  Always stuck on v1.82.  This is quite frustrating as I am am trying to update the system to patch against the Specture vulnerability.  I have a number of L540's and some update with no troubles at all and others have this exact same issue.

 

Anyone have a solution or see the same problems, please reply?

Hi jeremy_hynes! 

 

Welcome to the Lenovo forum discussion! 

 

If you are using a Windows 10 OS on the Lenovo L540, you can try using the Lenovo vantage app https://support.lenovo.com/us/en/solutions/ht505081?CID=ww:lenovosocial:20x9m6 to install the latest BIOS update. Let us know how it goes. 

 

Regards,

Thanks for the suggestion but sadly it only downloads the exact same BIOS installation utility and it runs normally asks for a reboot and when it reboots is boots straight into Windows 10 rather than performing the BIOS update.  When I double checked the history inside of Lenovo Vantage it reports the BIOS installation was successful.  I double checked and the system is still running v1.82 not the latest v1.93.

Thanks for updating us back! Let's try doing the steps below: 

 

1. Try downloading the BIOS firmware v1.85 first and install it first, then check if it will push through. You can download the BIOS v1.85 here https://pcsupport.lenovo.com/us/en/products/LAPTOPS-AND-NETBOOKS/THINKPAD-L-SERIES-LAPTOPS/THINKPAD-L540/20AV/downloads/DS037206?CID=ww:lenovosocial:20x9m6 (scroll down the page). 

2. If the BIOS firmware update succeeds to v1.85, try downloading the v1.86 and repeat the whole process until you install the v1.93. Let us know how it goes. 

 

Thanks!

I have tried v1.85 and v1.87 both in Windows utility and Boot CD formats but I get the same result it says its successful but it is not and just stays at v1.82.  I even tried both methods to reflash v1.82 but it says it already has the current version installed and closes the utility.

I've fix same problem. Cut the power. Pull the battery. Open back panel. Pull the bios battery. Wait 5 min. Than recover all. Open pc push F1 enter date time. Than update latest driver over windows. ?
