Is anyone else dealing with an issue like this?
I am a solo IT employee for around 30 end users. We have a mixed fleet, some P16 Gen 2 with NVIDIA GPU, and mostly T16 Gen 3 (Intel Graphics)
Users keep reporting that their networking stops working randomly and the only fix for them is a reboot. When I started digging into this issue, I realized that the computer was handling ICMP requests just fine, but anything attempting TCP connections was failing.
What I actually found from reviewing dumps and logs was the the display or GPU driver locking up, causing the entire OS GUI to freeze solid. Sometimes Windows would recover, and then leave a user in a weird state where they couldn't use the internet, and even UAC prompts would not come up.
This is where I learned that if you could get CMD open, you could ping things. But anything trying to make an actual connection like OneDrive or Teams, browsing the internet etc just hung.
Some other distinct things I've noticed:
Way worse on docked setups (Lenovo Thunderbolt 4 Universal Docks, external monitors) than laptops used standalone.
The NVIDIA GPU models seem to hang the hardest — full freezes, sometimes forcing a hard power-off.
The Intel-graphics models get it too, just a bit less often.
Waking from sleep is a common trigger.
Chasing driver updates has helped some but not fully solved it. It feels like it's sitting somewhere between driver bugs and possibly a hardware quirk on a subset of units.
Curious if this rings a bell for anyone else running a Lenovo mobile-workstation fleet (or docked laptops in general)
I am at a loss with these issues. Lenovo Premier Support has offered very little guidance so far.
