This box (d745) just reported battery needs replacing, maybe BIOS settings have invalid values which could be impacting or causing bug to occur, maybe also why it occurred first time, but didn't on reboot.
Regardless I went into BIOS & changed setting to 'disable' (floppy drive)
On rebooting into Lubuntu daily 'live', I started KDE partition manager, and box (scanning) did open but was too quick for me to read anything, so issue has no gone completely, or at least didn't re-occur this time.
