I have a no-name netbook-style laptop running up-to-date Fedora 29.

When I close the lid, fedora almost always puts the notebook in sleep
mode. Unfortunately, once in a while, it does not. And then my battery
runs down.
The notebook has a light that indicates sleep by blinking slowly.
Unfortunately, it is not visible while the lid is closed. Bad design.
I could put the notebook to sleep and then close the lid, but this is
quite a bit more fiddly.
Why would Fedora fail to sleep once in a while?
Does anyone else experience this?
How would you go about diagnosing this problem?
(My fear is that this is a firmware bug. I'm pretty sure that there will
never be firmware updates.)
