The laptop does not suspend when suspend key is pressed, it is not suspended even when I type
command systemctl suspend -i .
One of the usb ports does not work and usb2-port3 over-current condition message comes at dmesg.
- OS: Ubuntu 20.04 ;
- HW: DELL Latitude
The laptop successfully goes to sleep in Windows 10 mode(dual boot).
