RAR archive for the HP EliteBook Folio 9470m, whose motherboard was designed by Inventec according to the name. The contents are not described, so expect schematic or boardview material that is useful for diagnosing this ultrabook. Such documents help locate components, follow the charging and power-on circuits, and find test points while checking for shorts on the main rails. Inventec boards carry a 6050A-style PCB number, so read the number on your board and compare it with the files inside before relying on them.
