The battery is definitely swollen and needs to be removed ASAP. If you remove the battery and plug in the power adapter and you still get no power then you have a bigger issue. If there is still no power then your motherboard is probably dead.
With the battery removed, it should be possible to boot your m15 with the ac adapter plugged in. If not, please check the ac adapter, does its power cord led work before and after being connected to the laptop?
Please share an update. Thank you.

I disconnected the battery and the laptop runs fine. My work laptop had the same issue and also my xps has slightly swollen battery. It seems like a larger issue. Where do I buy the new battery?
Hi @volker_schmidt thank you for sharing update that your laptop runs fine on ac power adapter. This is very good news.
The larger issue is that these batteries may have been in storage for more than two years with the Lithium-ion chemistry cooking away, before they are put into a new laptop. The Windows 10 Battery Report will tell you its actual age. That's the trouble with built-in batteries, and they are difficult to replace.
As you have only disconnected the battery, the chemistry continues and if it bursts or otherwise gets punctured, you will have a real safety problem. WARNING: Do not wait, carefully remove from laptop, get it out of the house and carefully dispose of this hazard now! Dell seemingly does not sell replacement Lithium-ion batteries anymore.
Dell computers are very particular. Only get a vendor certified replacement new Dell OEM battery, e.g. PartsPeople, etc.
