Ever since I installed Manjaro I’ve been able to use bluetooth without any problems- until last night, when for no reason my keyboard disconnected. I checked gnome’s settings manager and found that gnome said there was no bluetooth adapter found- what do I do?
I’m not 100% what I was doing at the time that may have caused this to happen. I remember installing lib32-pipewire around the time it happened- but it could be unrelated?
… just by itself or along with a full system update?
(partial updates can and soon will cause problems)

for system information … the bluetooth adapter should show up there
… just by itself or along with a full system update?
(partial updates can and soon will cause problems)
Full system update, always make sure of it. That’s why I think it could be related, maybe some bluetooth package updated when I installed lib32-pipewire

I don’t really see anything else from around that time…? I did install lib32-gnutls (forgot about that) but I don’t see how that could be related

there is no section about Bluetooth in that inxi output
(it should appear in between “Network” and “Drives”)
→ the system does not see the adapter at all
does a reboot / power cycle change that?
If not:
the hardware may be broken or just disconnected
I have no other ideas.
There was quite a big update (yesterday, for me).
you can scroll up/down in that list
(you probably know that - but not everyone does …)
But I don’t think the reason is there - the hardware might simply have given up the ghost …
does a reboot / power cycle change that?
No, tried that several times 
I thought it might be related to dual booting windows (because for whatever reason that knocks out my wifi and I have to juggle booting into windows and linux until it works)
the hardware may be broken or just disconnected
Seems like it, as much as I was hoping that wasn’t the case, because I’m pretty sure it’s on my motherboard? Guess I have to find a dongle then…
To be accurate, you can install things on their own as long as you don’t update the local database.
ie
sudo pacman -S package
can’t possibly cause a partial update, unless you’ve previously run some variation of
sudo pacman -Sy
# or
sudo pacman -Syuw
Last time I checked (which was quite some time ago) the pamac GUI forced updates anyway, because it likes to update the local database when it’s opened. Not sure about the CLI version.
