Since about 3 weeks I have the problem that sometimes when I lift up my T470p from the desk, it restarts immediately without a reason.
Does anyone know what could be the reason for that?
My guess would be loose battery contacts or something like that, but if I am trying to move the battery, nothing happens.
Before anyone asks, I have already installed the latest updates, as well as the Bios.
Thanks in advance for any clues how to solve this.

have had have the same problem. I've had a feeling it has something to do with static charges. But now it seems to happen more often when I am resting both my palms down for writing, then reposition the computer with that same grip. Something must be shorting. I have to unplug and remove the battery to get started again.
I have already gotten it serviced once. And after that, it was good for almost a month, now back to same issues.
Thankfully it's covered with 3 year on-site warranty.

Problem still exists for me even after service. It is more often seen when the device gets used for a long time. I generally see after using the device for more than 1hr of usage on battery only. I think it could be related to heating of device.

To be clear, problem exists for me as well, even after they changed the motherboard.
I think you might be on to something with the overheating issue. When I restart it quickly after I've lost power I am getting thermal warnings in the Linux boot sequence. However, it will never power off by itself. It seems to always want a human touch.

Unrelated, I have a Dell Latitude E5450 that did the same thing, powered off when lifted. It ended up being a lot of loose screws, that allowed the chassis and mobo the flex enough to trigger a power cutoff. I noticed the HMM has a page on the proper tightness of screws (I don't remember if it includes torque specs, but I don't think it does). Perhaps that is why some mobo replacements fixed the issue and some didn't?

I experience the same issue intermittently. My theory is that it is caused by a combination of high temperature and slightly bending the motherboard.
