Laptop abruptly falling asleep? Check your watch strap


I exchanged my Lenovo ThinkPad X260 work laptop for the newer T14 model last Wednesday, and spent the first half of the day setting up the new model. When I started using it in the second half of the day, I had 3 instances when it went off into hibernate mode without any warning, while I was working. In fact, the first couple of times it happened during the same call. The only silver lining was that the new machine was quite fast & didn’t take long to start after hibernating.

The battery levels were full, and disabling auto sleep didn’t seem to make any difference. I didn’t seem to be triggering any special gesture on the trackpad or fingerprint reader either. Google results didn’t have much beyond the usual check for defects/battery/OS issues. The only tell tale sign was that I was using the keyboard when this happened.

It was on the 3rd instance that I suspected that my magnetic watch strap was engaging the lid closure detection magnets built into the palm rest. A quick tapping around the suspected area confirmed my suspicion – it was my magnetic leather watch strap that was triggering the hibernation as the laptop thought that the lid was closed. Don’t think there is a solution other than using non-magnetic straps when working directly on the laptop.

I do use a laptop stand with external keyboard & mouse when working from home, so magnetic straps should be fine. However, no special watch straps when in office it seems 😦
