Inspiron 5558, plugged in not charging with orginal dell charger that came with the laptop and 0.48 ghz instead of 2.4. I am 100% sure that the cords are 100% fine. The wierd thing is that it sometimes charges and sometimes it does not. But when is starts charging, it will not stop until I remove charger or battery. I found someone on reddit that had the exact problem with the exact things that happens to him and the exact model. I updated the bios and all other stuff on my pc up to high performance. Sometimes it will charge in 1 hour and sometimes it automatically charges. Sometimes it take about 2 minutes to start. Once it took up to 5 hours. And Dell of course wants that easy money by not letting people buy cheap good chargers and letting them buy there <profanity> $60 chargers.
We will need to determine if the issue is with the AC adapter or Battery. We will have to check the status of the adapter in BIOS; if the adapter is not detected properly the system will continue to receive power but will not charge the battery. Please follow the steps mentioned below to check if the adapter is detected properly.
1. Start the computer by pressing the power button
2. Press the F2 key 2-3 times you will now be on the BIOS screen.
3. Under the Main Tab look for the option that says AC Adapter Type
If the Adapter Type says Unknown or None with the adapter plugged in.
4. Reconnect the adapter to the machine and if the status now shows as Unknown then the AC Adapter needs to be replaced.
Also, I would suggest you to run a thorough test on the battery. You can download Support assist from the link below and run the PC CHECKUP on Battery to check for issues
Please let me know the findings.
