RE: (INSPIRON 5559) CRACKLING SOUND WHEN UNPLUGGING ADAPTER, WHY?
Welcome to our community.
You’ve reached the right department. Please do not worry. We’ll surely try to assist you. We’ll have to update certain drivers to resolve the issue. We request you to provide us with the following information, so that we can check and provide you with the right drivers.
1. Service tag/ express service code
2. Email address
3. Registered owner’s name of the system
The Service Tag is a 7-character code, and the Express Service Tag is a 10-digit code that is a numeric version of the Service Tag. Both codes are on the bottom of your laptop. You can also refer to this link which is a video that shows steps to find the service tag.
