There could be various reasons why your laptop cable is not working:
1. Physical damage: The cable might be frayed, bent, or otherwise physically damaged, causing a break in the connection.
2. Loose connection: The cable may not be securely plugged into the laptop or power source.
3. Power adapter failure: The power adapter itself could be malfunctioning or faulty.
4. Software issues: There might be software-related problems, such as driver issues or power settings, preventing the cable from working.
To troubleshoot the issue, you can try the following steps:
1. Check the cable for any physical damage and ensure it is securely connected to both the laptop and the power source.
2. Try using a different power outlet or power adapter to eliminate the possibility of a faulty power source.
3. Restart your laptop and check if the cable starts working.
4. Update your laptop's power-related drivers and check the power settings to ensure they are configured correctly.
If these steps don't resolve the problem, it is advisable to seek professional assistance or contact the manufacturer for further support.
