I recently deleted windows and installed Solus (as the only OS) on my (ancient) Thinkpad T400. The machine is only used once a week, to record using Audacity. Which works fine.
The issue comes when the Battery runs flat during suspend.
After finishing the recording, editing and burning it to CD. I close the laptop lid, and put it away. This is where the issue comes, when I open it up again the following week, it boots to grub fine, but then stays on the flashing cursor for a couple of minutes, and then it enters Emergency mode with the :/# command prompt and a flashing cursor.
From here, I'm not sure what to do.
For hardware it is a bog standard Thinkpad T400 with 4Gb of ram (I think). The only change I have made to the machine is to install a new, larger HDD. As the T400 doesn't have UEFI boot, it is using legacy (grub) boot.
