OK, I'll bite what's a "DAP"?

As to running a laptop or most battery powered devices like them, that can also run with
an adapter, they can usually also run on the adapter with the battery set removed.
In fact it makes them much lighter, and turns them into a "transportable" device. This
can be handy when the device is only operated at home /or office, using a mains adapter
and in a vehicle using a DC adapter. No Li battery = no hazard.

All battery sets can be removed, it usually just involves opening the case and unplugging
the battery set from the circuit board.

Luck;

P.S. If the device has leads from the battery pack that are soldered to the circuit board,
then cut the leads at the battery set, leaving something to splice on a new battery set's
leads (just in case you want to replace the battery at some point).
