4 Amber 1 white light blinking

The blinking pattern you’re observing on your Dell Inspiron 3558 (4 times amber followed by 1 time white) indicates a Battery Issue. Since your laptop is an older model, it’s possible that the battery has reached the end of its lifespan.

Battery Replacement: You’ll need to replace the battery. You can find compatible replacement batteries for your Dell Inspiron 3558. Here’s a link to a replacement battery that you can consider.

Battery Report Check: Create a battery report to check the status of your current battery.

1. 1. 1. Open a Command Prompt window (search for “cmd” in the Start menu).
      2. Type the following command and press Enter: powercfg /batteryreport
      3. This will generate a battery report. Locate the report file (usually saved in your user folder) and open it.
      4. Compare the Design Capacity value with the Full Charge Capacity value. For a healthy battery, these values should be nearly the same.
