Laptop Hp 15-bs 145 tu (2 years old)
ubuntu version 18.04 LTS
Once charge reaches 60%, it keeps on charging discharging each minute. Also, around 20% it automatically shuts down without giving any warning of low power.
I already tried calibrating (draining battery to 0% and charging while it is turned off till it shows white light). But even in that case, once it reaches 60%, white and red light keeps changing.
(white light = fully charged, red light = charging).
What should I do ? Should I replace battery ?
