Update: HP Laptop: I have upgraded BIOS on the HP6710b laptop to F16, which included upgrade of video BIOS. It had no effect on the boot behaviour.
ASUS Laptop: I have realised that I CAN get the grub menu - its just that the screen is black and I can´t see it. (ie: I can navigate the grub menu using arrow/enter keys and select various options from memory of where they are in the menu tree). Behaviour is essentially the same as HP laptop - it will only boot successfully into 4.15.0-48 after a previous failed boot. A first boot fails. Note that I tried a fresh install from the mini.iso on the asus laptop. Boot problem is the same on a fresh install of 4.15.0-48, not just upgrading from earlier version through software updater.
