My Debian 8, running on HP mini 210-2006, shows a strange behavior:
When I shut it down, and then power it on again in the interval till about 2 hours, the system does not boot, just show a black screen and power on the fans (and maybe the Hard Disk), but does not even show the grub and bios entries, and the keyboard is still unresponsive. In this case, to boot, it is necessary to make a hard reset, and then the machine boots normally. The shutdown process also seems too fast. When the system is put in the suspension mode or hibernation mode, usually (but not always) the same thing happens when it's called back, and then a hard reset is necessary to enter the system. But, if it just rebooted or powered on after something about 2 or 3 hours (or more), it does not happens, the system boots normally. I have Windows 7 and Ubuntu in the same machine, it just happens to Debian 8. Looks like Debian isn't really shutting down before at least two or three hours after the shutdown command is executed. It's strange but Debian keeps in a "hibernation-like" mode for few hours before really shutdown, and in that period it can't be powered on. I've installed the latest bios through Windows 7 (seems HP does not offer an update for Linux).
When the boot succeeds the following ACPI errors always happen:
