If you don't remove the battery immediately, it will destroy the system.  Get rid of it  -- now. Then purchase a replacement battery.  Even if you'd purchased the system direct from Dell, the battery warranty is 12 months - you'd be buying a new battery anyway.  Either way, a battery at under $150 is less expensive than replacing the entire system, which you'll soon be faced with doing if you don't remove the swollen battery now. Here's the battery: [URL]
XPS13 7390 2in1, after 14 months of daily use, the lid is ajar when closing because the swelling battery (underneath keyboard) bends the palm rest up, and one month later, I was afraid of breaking the screen and case because of its more bend. Anyway, when contacting the local store for battery replacement they did not recognize me to be a credited customer just because I brought it from eBay instead of from the local store and required an existing partner to order the part. -_-'' [IMAGE] The battery turns to balloons [IMAGE]
