Abstract
Wireless Charging become popular overtime to the mobile products, All in One (AIO) PC usually
embedded Wireless Charger inside the stand and Wireless Charger is required to standby at
S4/S5 PC OFF Mode.
Standby power consumption of Wireless Charger is high (around 150mW) which cause PC not
able to meet ERP‐LOT3 S5 regulatory requirement. (S5 Power < 1W)
Exist strategy on AIO PC is simply disable Wireless Charger at S4/S5 which negatively impact user
