Set battery charge limit in ubuntu 24.04

ref:

• Setting the battery charge threshold in Ubuntu 24.04 LTS

上次買的 lenovo legion 在 windows 7 下有電池充到 80% 的功能。
覺得這樣電池好像活得比較久，所以想在ubuntu 看看有沒有一樣的功能。

看起來是 tlp 這個 package
follow 說明

sudo apt install tlp tlp-rdw
sudo systemctl enable tlp
syudo systemctl start tlp

然後修改 /etc/tlp.conf

# Battery charge level below which charging will begin.
START_CHARGE_THRESH_BAT0=65
# Battery charge level above which charging will stop.
STOP_CHARGE_THRESH_BAT0=80

然後再啟動

$sudo tlp start
TLP started in battery mode (auto).

$ sudo tlp-stat -b
--- TLP 1.6.1 --------------------------------------------

+++ Battery Care
Plugin: asus
Supported features: none available
Driver usage:
* natacpi (asus_wmi) = inactive (laptop not supported)

+++ Battery Status: BAT1
/sys/class/power_supply/BAT1/manufacturer                   = GIGABYTE
/sys/class/power_supply/BAT1/model_name                     = Aorus 15
/sys/class/power_supply/BAT1/cycle_count                    =      0 (or not supported)
/sys/class/power_supply/BAT1/charge_full_design             =   6514 [mAh]
/sys/class/power_supply/BAT1/charge_full                    =   6514 [mAh]
/sys/class/power_supply/BAT1/charge_now                     =   6258 [mAh]
/sys/class/power_supply/BAT1/current_now                    =   1066 [mA]
/sys/class/power_supply/BAT1/status                         = Discharging

Charge                                                      =   96.1 [%]
Capacity                                                    =  100.0 [%]

看來沒效，因為 laptop not supported
NB 是 Gigabyte AORUS 15X, i9RTX4090
看來還是買 lenovo 還是 asus 比較保險。

不然就要參考：優化 Ubuntu 電池壽命
另外，這邊 有 support list： ASUS, MSI, LG,Lenovo, Samsung, SONY, Toshiba. Apple
--- 所以沒有 Acer 跟 Gigabyte，要用 ubuntu 的話，記得不要買這兩家的 NB
