Windows 10: Is this AC Adapter ok for an HP EliteBook 8540w I just picked up?

Is this AC Adapter ok for an HP EliteBook 8540w I just picked up?
--- Are there better choices I can look into?




I’m using the 19Vdc 4.74A as a guide based on the battery compartment information which I suppose is really for the battery if there was one in it.

According the HP manual the AC Adapter P/N is 693712-001 & replaces whatever the original PN is but the manufacturer’s PN isn’t included in the charger buy’s company information.

In the additional info section, it states
“Attention! Please make sure the part will match your laptop. If there is no central smart-pin in the connector of your original AC Adapter, please stop bidding this item.” I don’t know how to determine that because I don’t have the original AC Adapter. In the connection port of the laptop I do see a gray central receptive section that an HP AC Adaptor cord I’m using accepts the center pin, but I don’t know if that is a central smart-pin. If it is it appears to me I shouldn’t have a problem ordering this unit.

Smart AC Adapter capacity

Hi

An AC Adapter is the small black box that is typically located on the Power Cord that you plug into a wall socket to provide AC power to the computer and charge the battery at the same time.

An AC Adapter should have been included with the device, it is important to use an adapter that is compatible with the device you are using.

I would recommend that you contact HP for more information.
