Just tried that, selected sleep then waited until it did, then closed the lid, then opened it and nada. Power light stops blinking and goes on full but the screen is blank. I left it for a few minutes but no joy. Not a major issue and I can wait for it to be fixed in the next stable type11/boot123.
