WetGeek Interestingly, my keyboard still hasn't stopped working since I installed tld.
It's the next morning, now, and this Bluetooth keyboard is still working well. Needless to say, I don't type much in my sleep, but before I installed tld, just not typing anything for a little while was enough to cause the problem I described. I'm not calling it solved quite yet, but I'm very happy with how things are going so far.

Unfortunately, it didn't last. I've used the keyboard a lot since then, but this morning it again stopped working in the middle of a sentence as I typed an email. I shut down the laptop and restarted it, which fixed things as usual.
So, I'm still looking for a better solution, in case anyone thinks of something else I should try. Installing tlp apparently changed the severity of the problem from several restarts per day to one restart in a couple of days, so I'm not ready to uninstall that yet, but it's obviously not a complete solution.
WetGeek Could you please provide the info about your bluetooth chip from lspci -v?
@WetGeek Removed post as the formatting was significantly broken. Please put your log on either pastebin and link that, or use Markdown code blocks, thanks!
WetGeek Sorry about all the comments that were converted to headings by the forum software. I'd edit the message and escape all of those #s, but it's probably not worth it this time. I'll try to remember that before I post the message with command output. There will undoubtedly be comments in most of those.
WetGeek No problem, Markdown parsers can be weird.

There is no card, and no dongle. Wi-fi is built into this Dell laptop. It's a DELL PRECISION M4200. The only USB devices in use are my wireless mouse and webcam.
I had no idea how an internal wi-fi radio might be identified on the PCI bus, so I sent all of it, but I knew from the start it wouldn't show up as a USB device. Thanks for all the help. It's now working for days at a time, instead of a couple hours at a time, so that's a big improvement.

[deleted] Intel 7260 has integrated bluetooth.
Yes, it does. What I'm looking for is something that causes the Bluetooth keyboard to stop working, while the Bluetooth settings continue to report that Bluetooth is ON, and the keyboard is paired, and connected. All the while, the wi-fi network controller has never been a problem.
