The Lenovo engineer confirmed me that "Battery Charge Threshold" is available in Lenovo Vantage **_merely for ThinkPads_**. Then I asked — why on earth can't "Battery Charge Threshold" be universalized to all Lenovo laptops??? She escalated to her supervisor who said the same thing.
  • Then they accessed my laptop remotely, and confirmed that "Battery Charge Threshold" doesn't befit my model. Supervisor concluded that he will escalate my request to his engineering team, but he can't promise any changes that shall take at least 6 months.

 How can I enjoin my Lenovo laptop to stop charging 

1. when the battery attains 80% of my choice?

2. at a maximum cap of my choice?
