With my XPS 13 9350 setting the critical action to do nothing is certainly better than letting it go to sleep. It’s just a matter of dismissing a dialog instead of having to restart everything. Also, it seems like its hitting this condition a little less after I set the critical battery action to do nothing. A real solution would be better and I also would welcome an answer as to how to fix this instead of simply circumventing it like I am doing now. As far as I can tell Dell no longer sells new batteries…I have been in contact with Dell about it getting a new one. I would rather not get a new one as the 3rd party one is working fine except for this hibernation issue that popped up after I put the replacement battery in.
