What are the common signs of a bad laptop charger?
A bad laptop charger can exhibit several signs that indicate it’s time to replace it. One common sign is that your laptop is not charging at all, or it’s charging very slowly. You may also notice that the charger is getting excessively hot, or there’s a burning smell coming from it. Additionally, if the charger’s cord is damaged or frayed, it could be a sign of a bad charger.
If you’re experiencing any of these issues, it’s essential to inspect your charger carefully. Check the cord for any signs of damage, such as cuts, frays, or burn marks. Also, ensure that the charger is properly plugged into both the laptop and the power source. If you’re still unsure, try using a different charger to rule out any issues with your laptop.
How do I identify a faulty laptop charger?
To identify a faulty laptop charger, start by inspecting the charger’s cord and plug for any signs of physical damage.
