Hi,

I can't find 756413-002 in Part store

    http://partsurfer.hp.com/Search.aspx?SearchText=756413-002

but the HP Elitebook 840 G3 accepts both 45W and 65W adapters as shown:

Operating voltage and current:

• 19.5 V dc @ 2.31 A – 45 W
• 19.5 V dc @ 3.33 A – 65 W

I actually use few PSU's for my laptops. For travelling I use a lighter one (lower wattage) ......

Regards.

ok.  I plugged in the 65W one and it is working.

Thanks.
