I have this problem now and it has been recurring for months. When the laptop does boot, it often has features that are non-operational (e.g., no HDMI, no Bluetooth, no audio, etc.). When it does boot with features operational, it often takes 20secs for a program to start (e.g., sudo, cp, Firefox, Aoo, etc.).
Can you help?
