XPS 13 9350, new battery, does not turn on, power button LED is on

Hello All,

I just replaced the battery on my Dell XPS 13 9350 since the previous battery got swollen. I ordered a genuine Dell replacement battery and installed it just now but already running into problems...below is a quick outline of what is going on...

* replaced battery with genuine dell battery since the  old battery swelled

*laptop will not turn on

*power button LED however is always ON

*cannot seem to turn off the power button LED unless I unplug the battery

*the laptop starts running hot as soon as I plug the battery in

I have been fighting battery issues with XPS 13 for quite some time...any help will be greatly appreciated.

***update***

I tried running the laptop with just AC power and it does the same thing...the power LED comes on, stays on, won't turn off (unless I pull the AC power) and the laptop still won't start...please help...
