No USB? Don't fret! Try: Different ports, restart, another computer. Check: Drivers, loose connections. Fix: Update drivers, format (backup first!), scan for errors. Advanced: Disable suspend, use recovery software. Hardware issue? See a technician. Stay safe, back up data! - Annaliza Beth14-Dec-2023
