How to check whether tlp supports my laptop and is working properly?
My laptop is

To test , in /etc/tlp.conf, modified line no. 431 & 432 as
START_CHARGE_THRESH_BAT1=30
STOP_CHARGE_THRESH_BAT1=80

Then ran

jagdeesh@jld-lap-HP15-kub2004:~$ sudo tlp start
[sudo] password for jagdeesh: 
TLP started in AC mode (auto).
jagdeesh@jld-lap-HP15-kub2004:~$ sudo tlp setcharge 30 90 BAT1
Error: battery charge thresholds not available.
jagdeesh@jld-lap-HP15-kub2004:~$

Presently the battery is 98% charged and is charging. Whenever I sleep it and switch off mail switch and again start using by making power on, always charging-discharging takes place from @ 95 to 100%.
This laptop always being at home , I don't need battery backup for it and want to maximize battery life. So want to set to charge up to 90% only when it is discharged to 30%. How to configure this and check it is working?

I don't use a laptop all that often, so I'm not the expert. However, have you tried the tlp website? They have pretty comprehensive doc, at least to my eyes.

Battery thresholds are a Thinkpad-only feature in tlp
https://github.com/linrunner/TLP/issues/444
which leads to
https://github.com/linrunner/TLP/issues/321

Have you looked at your bios to see if there is a setting for this there? My Lenovo has settings for it there.

Thanks jglen490 and claydoh
Visited tlp website, seems my laptop is not supported.
