I have installed Ubuntu 24.04 on a Lenovo T460s. I notice earlier that the Laptop shut down unexpectedly. Few moment after, i have checked that, when the second battery of my Laptop runs out, it shut down imediatly.
I have installed some software such Battery Notifier to notify me when the device reach some point of charge.But it not resolve my issue. Is it OS problem or Firmware problem, or even Hardware.
Thanks for helping me.
