TLP 1.4 Test: Battery Care for Non-ThinkPads

Introduction

TLP has supported charge control thresholds for ThinkPads since the beginning. With release 1.4, support will be extended to laptops from selected other vendors for which a corresponding driver already exists in the Linux kernel.

Since I don't own any of the newly supported laptops, I'm reaching out to the community of TLP users with a request to test the new functionality on their hardware.

Subject: [PATCH 2/3] thinkpad_acpi: add support for inhibit_charge

Lenovo ThinkPad systems support to hold battery charging
via a manual override called Inhibit Charge.

This patch implements that feature and exposes it via the generic
ACPI battery driver in the generic location:
