In my case I suspect that the problem might be caused by a non-compatible power adapter (I am using several ones). Since I reported the problem I changed this power adapter and did not see the problem again. Do you use a non-Dell or non-compatible Dell power adapter ?

The DE should have nothing to do with it. This is clearly a kernel/BIOS problem.
