Weird Inspiron 15r 7520 charging issues


My 7520 will charge until the battery reaches 100 % after that it won't keep it charged and the battery drains until it is dead, even with the charger plugged in. After a while (a day or two) I can plug the charger back in and it will start charging, but only after it died. If I plug in the charger in at say 50% it will not begin to charge.

Any help is greatly appreciated.

Thank you,

Daniel Lee

RE: Weird Inspiron 15r 7520 charging issues

Hi Daniel,

Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible?

Restart the system and press f2 key to enter BIOS - check the adapter status in BIOS with and without the adapter plugged in. Also, wiggle the adapter cable at the end and see if the status changes in BIOS at any point. 

Update the BIOS and check.

Test another power adapter. If the adapter fits in loose, then the dc port needs to be replaced.

If there is no warranty, then you could contact our team to get a quote for a paid service call - http://dell.to/1vnT6CQ 

Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.

Let us know if you have any other queries.
