I have swapped the original Shutdown menu with Radkys excellent Pupshutdown. Pupshutdown has suspend to ram icon preinstalled.would be even better with a new sub-menu item in Shutdown for Suspend to RAM
I know.....I just couldnt resist this advertisement of Radky`s great Pupshutdown (which got new update yesterday)
