L440 BIOS not updating

2018-12-24, 18:11 PM

Hi everyone,

 

I have quite a few L440's that will not update to the latest BIOS. At first I thought the BIOS wasn't updating only for machines that were at versions 1.81 and 1.82 however now i'm seeing some machines that are upgrading from those versions without an issue. Seems to be happening with Windows 7 and 10.

 

symptoms:

Execute BIOS update via winuptp.exe or via command line winuptp.exe.

Machine asks if i want to update the BIOS i select yes. 

It informs me the machine will reboot. 

Machine reboots however after the Lenovo screen I do not get the BIOS is flashing screen it just reboots to windows. 

 

Troubleshooting preformed:

- Full shut down of machine.

- Updated all drivers via system update app 

- I have not tried using a bootable CD as I need to do most of these remotly. 

 

below is the log from WINUPTP.log

-------

Can confirm it's happening to me as well. Tried both the EXE and the Bootable CD way, no luck. CD worked fine with another identical machine, but not with the one I'm trying to update.

 

I opened a support case with Lenovo as the machine in question has other issues, since they typically won't let a case proceed unless the BIOS is the latest, I tried to update it beforehand, the machine still has a few months left of the 3y warranty.

 

Will let you know once I have an answer

 

There is at least another case of this happening.

Well, bad news for you I guess.

 

Since the BIOS could not be updated, after several calls to tech support they opened a case with the local shop and I sent the machine to the depot for warranty repairs. The depot called the company driver/messenger directly and he picked it up yesterday, so I didn't get a chance to ask what they did, but based on the fact that the BIOS shows a wrong generic model number, and a zeroed out UUID, I'm gonna go ahead and guess that the motherboard was replaced.

 

I'm guessing it's a hardware issue with either the BIOS chip or the EC. Given that mine had a sleep issue that could not be resolved with software, I'm going to double down on my theory of an EC failure.

Hi

 

I had the same problem to update BIOS with several M440.

My solution to the problem was to disconnect the battery and the CMOS-battery for a few minutes.

After that the BIOS upgrade worked great.
