From: Hans de Goede <hdegoede@xxxxxxxxxx> [ Upstream commit 3a06b912a5ce494d7b7300b12719c562be7b566f ] It turns out that the "T3 MRD" DMI_BOARD_NAME value is used in a lot of different Cherry Trail x5-z8300 / x5-z8350 based Mini-PC / HDMI-stick models from Ace PC / Meegopad / MinisForum / Wintel (and likely also other vendors). Most of the other DMI strings on these boxes unfortunately contain various generic values like "Default string" or "$(DEFAULT_STRING)", so we cannot match on them. These devices do have their chassis-type correctly set to a value of "3" (desktop) which is a pleasant surprise, so also match on that. This should avoid the quirk accidentally also getting applied to laptops / tablets (which do actually have a battery). Although in my quite large database of Bay and Cherry Trail based devices DMIdecode dumps I don't have any laptops / tables with a board-name of "T3 MRD", so this should not be an issue.
