Hi Esteban, This sounds like your host OS is powering down your laptop's HDD while on battery, to save energy. Plugging it in triggers a different rule that selects "performance" over "energy savings" and keeps the drive up & spinning constantly.
I would check the Win10 power management rules to verify this. You can also select a different power profile when on battery there, or create a new one (such as "power savings except for the hard drive" when on battery). -Ted -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html
