I recently installed Ubuntu 19.04 on an HP ProBook 430 G3 and discovered the following issues. The battery won't charge when AC pluged-in until the level drops below 15% or less, sometimes even then I have to pull the plug and insert it several times until it starts charging. Also, when on battery power the performance is bad, really bad. I think it has something to do with CPU scaling or something. First I figured there was something wrong with my installation, so I erased everything and installed Lubuntu 19.04, but the same issues appear.
I would like to disable CPU scaling when on battery power and make the battery charge all the time when on AC, not just when the level drops bellow a certain threshold.
Can you help me do that? Thanks!
UPDATE Battery discharged to 45% then plugged the cord in. After 1 hour the batter was down to 3%, to my surprise it didn't charge at all. I had to pull the plug and reinserted like 5 times to get it going. This is becoming very frustrating.
