I turned off the machine when the power got low and charged it until the happy light went out.
I'm only using Firefox/Chromium as supplied with the Pinebook - both seem to be working now.
Seems great to me.
Maybe your browser wasnt working because you did something wrong when trying to fix something and after the fresh restart, what you did was reseted ? (if you played with sysct or did echo XXX > /proc/sys/.... or something like that.
Maybe yesterday you did open at the same time firefox and chromium and you were too short in RAM ?
Maybe your CPU was busy running some garbage ?
Next time, if you have such issue, you can start by running and showing us the result of cat /proc/meminfo ??
And also you could start htop or top (or any other system monitor application you want) in the same time you run your browser ?

Maybe this application is not working and this may be an issue of the distro/application and may not be related to pinebook ? By the way which OS is shipped by default with this laptop ? armbian ?
Maybe not much people are playing with it.
If I were you, and If I really want this game, I would start searching on the OS forum if anyone is aware of this BUG. You should try to find if this application has a web site with BUG report or forum or something like that
If needed, I would try to rebuild the application in debug mode and will try to get a core. So I could post the bug report to the community.

Can't remember the one distro I used a good while ago that worked like windows and installed them without any effort.
It's half installed now but mentioned a missing driver element I have no idea how to get.
I copied the PPD file using a pen drive which is perfectly mounted and accessible but refuses to eject citing "no such file" or similar.
So your printer is working, isn't it ?
Don't forget that you have an ARM system with small size in comparison to x86_64 ubuntu desktop OS. So it's not a surprise to me that several things that are present in ubuntu aren't in armbian.
But in this case, I think you could have installed the driver by installing some packages. (use google to find which package). But if it's working then dont touch it
Regarding the pen drive .... next time check in the command line.
I suppose the pendrive is automounted. So next time, after mounting it, run the mount command and find your pendrive entry. (do it also before plugging your pendrive to be sure of what you are doing).
Then eject it. By the way how are you ejecting it ?
Check again with the mount command to see if the entry has disappear. If not, then you may have an issue. As a work around you can unmount it using umount command

What had you on the screen ?
After how much time did you get something on the screen ?
Are you sure your system wasnt in the middle of the shuting down process ?

The 1.4GHz CPU speed I set on a previous boot has reverted to 400MHz.
How are the CPU speed changed ? If by doing echo to /proc/something then it's the expected behavior. This is not a permanent config change.
For the battery level, you should check it in the console to be sure that the low level is working
Unfortunately, I dont have yet the laptop so I dont know but it can be something like
cat /sys/class/power_supply/BAT0/capacity

Do you have something printed in the console just before it restart ?
For example a kernel oops or kernel panic

If you have the rebbot every 5-10 minutes, then try to run dmesg command after let's say 3-4 minutes and show us the dump. You may get some hints on what is going on.

Why do you have such issue and not other guys ?
It's either an hardware issue (so changing the OS wont fix it, and you may get hints using dmesg command), or you broke the configuration.
Good luck
