|
Different from other Qualcomm Snapdragon sc8180x and sc8280xp-based
|
|
machines, the Huawei Matebook E Go tablets use embedded controllers
|
|
while others use a system called PMIC GLink which handles battery,
|
|
UCSI, USB Type-C DP Alt Mode. In addition, Huawei's implementation
|
|
also handles additional features, such as charging thresholds, FN
|
|
lock, smart charging, tablet lid status, thermal sensors, and more.
