Hi,

Thanks for the post.I have tried the options but still it gives message that the battery charging disabled,please reseat AC adapter and turn on when the unit is back to operational temperature.

Hi Aravind.k,

Thank you for the response. Please reply with the options available in the Quickset (share screenshot if possible). I would suggest you to update the BIOS of the computer. Here is the link http://dell.to/U3sneH 

Note: Before updating BIOS please ensure that:
*Battery is 10%> or >10% charged
*Battery charger should be connected
*No external devices (flash drives, printers, external hard drives) should be connected.
*All other programs should be closed and documents saved

Please check the AC Adapter status in BIOS; check the ‘AC Adapter type’ status if it shows ‘Unknown/  Not Detected / 65W / 90W / 130W'.

Please reply if you have any questions.
