@lanodan @ocean @coolboymew there is an extra battery down there, and it does lock on so it's usable as an ordinary laptop or a tablet. it's just a key on the keyboard to release it, and it won't do it if an application is using the nvidia card, unless you press and hold for the emergency disconnect.
also the charger cord/docking cord will plug straight into the tablet-lid so it's still usable if there's a problem with the base.
it's a clever, well executed design, but QC was just not their strength. and until the newest ones, they're impossible to repair or upgrade.
