What this adapter replaces

This 200 W AC adapter delivers 19.5 V at 10.3 A through a 4.5 mm by 3.0 mm barrel connector. It is built as a direct replacement for compatible HP ZBook workstation docks and laptops that require this exact voltage and connector size.

Check your dock and cable needs

The unit ships with a US plug power cord and a transfer cable that converts the larger 7.4 mm by 5.0 mm tip down to the required 4.5 mm by 3.0 mm size. Verify that your device uses the smaller connector and that the transfer cable is fitted before connecting to the dock or laptop.

Thermals noise and power draw

The adapter accepts 100 to 240 V input at 50 or 60 Hz and supplies up to 200 W of continuous DC power. It operates silently with no moving parts and runs at normal temperatures for a 200 W external supply under typical workstation loads.

Questions about this item

Does the box contain everything needed to power the ZBook Studio 15 G4, or must I purchase the transfer cable separately?

The package includes the 200 W AC adapter, a US-plug power cord, and the required 7.4 mm to 4.5 mm transfer cable, so no extra parts are needed.

There are two adapter variants labelled A and B for this model; how do I decide which one to request?

Both variants deliver 19.5 V at 10.3 A with the same 4.5 mm by 3.0 mm output; the only difference is the external shape, so choose the one that matches the look of your original brick.

Will the 200 W rating actually run the ZBook 17 G3 with an i7-7820HQ and E3-1535M under full load?

Yes, the adapter supplies 19.5 V at 10.3 A for a full 200 W, matching the workstation’s peak power requirement.
