My Laptop shuts down during TEAMS calls

Hi everyone - please use the following mitigation plan for this issue while we work with Lenovo to uncover more of the root cause/solution to this: Lenovo Yoga L13 might shut down during Teams meetings (microsoft.com).
Sam Cosby,Teams Engineering PM
MicrosoftThanks bwilson for posting this early today!
Hi everyone - we should note as well that this is indeed only a mitigation, not a solution, towards this issue. For users who have reported this issue and are seeing this problem, please have them do the following as this was validated from an internal repro of the issue through a L13 device that was prepped to what we've seen from others who've reported the issue.
Microsoft is working with Lenovo to understand the specific root cause, but it appears a recent driver update from Lenovo helped trigger this issue along with the use of Teams while in a Meeting. See the list of Lenovo drivers related to BIOS/power/thermal management below for reference.
Best,
Sam
- Well, we have all L13's, so my work-around is specific to that Model. Good luck...
- Shutdowns happen both ways, with the cable plugged in or not (mostly with the cable plugged in, because that's how I used it most of the time).
Sometimes I'm running hours-long simulations (High CPU and RAM usage) alongside teams. But sometimes I'm just running Teams + Chrome and shutdown happens too.
Simulations or chrome alone are not the problem, since ALL shutdowns happen while in a teams meeting.
Temperatures are always below 80°C.
E14 is my personal laptop. Lenovo told me that if the hardware is ok, I should contact IBM for software issues. but so far, I've got no answer from IBM - As a .bat/.cmd file pal.
- Hey Razor, does this happen with the charger connected or not? As it seems for us the problem happens when the charger is connected to the laptop. Also check if your anti virus kicks in or any CPU hungry software is running also when in a Teams call. Does it happen to any other E14 laptops for your users?
It keeps happening on my E14(Intel)
Right now I've run the .bat even though I've already set the max power to 99% and only use a balanced profile. (I'm this much desperate
)
Things I've tried
- Set Max CPU to 99% // Fail
- Disable Hardware acceleration for Teams // Fail
- Roll Back thermal solution driver // Fail
So, maybe there's a different bug that's affecting only E14 model. Or theres a problem with my machine that somehow is only triggered with teams (I run teams around 30% of the time, and all shutdowns so far(around 10) happened while I was in a meeting))Another option if you're in a domain environment is to push the fix out via group policy using a computer power plan. I've done this for a few of our clients who were all experiencing the same issue. This will let you pick and choose which computers received the fix as well since you can just apply to a specific group of computers.
- What format did you use to push it? Powershell? Batch file?
- We deployed the script to 200+ machines and have not had a reported shutdown since. I hope it works for you guys too. We have not changed the Teams hardware acceleration setting either.
I've rolled back the driver, so hopefully, this will stop now. This picture shows how my power plan was set
- I used the Script provided by the ITGuy in this thread. Copy this into Notepad, I saved it as a batch file (.bat) and ran it on two machines. It does two things, sets the default Power settings and sets the Max Processor settings to 99%.
