I've just installed LM13 MATE on my laptop (HP G70) and every time I start up I get a warning "Battery may be broken - battery has a very low capacity (38.9%) which means that it may be old or broken". The laptop's plugged in, and when I close the warning, the indicator shows "fully charged". Unplugged, the power statistics "time to empty" is around 50 minutes.
I've got LM13 Cinnamon on another partition and haven't had any such warnings there, and none in the old days of Windows. I rarely use the laptop unplugged anyway. Is there any way to stop this warning (other than buying a new battery)?
