The machine is the HP Pavilion.
There is limited operating paperwork with this machine.
I have searched in the battery compartment as suggested in the paperwork, and come up with:-
Model :- 15-p209na
P/N :- LOD87EA#ABU
I am hoping to use this machine occasionally as a remote monitor from the DVR.
Thank you, ***** ***** worth the money to get a definitive answer. Pity I did not do my homework first.
