How to use

Before installation, power off the desktop and disconnect it from mains power. Open the chassis according to the HP service instructions for the specific model and remove the existing power supply by detaching its connectors from the motherboard and peripherals and unscrewing any mounting fasteners. Install the HP L28758-001 by aligning it in the SFF bay, securing it with the original screws or compatible fasteners, and reconnecting all power connectors to the motherboard, drives and other components. Close the chassis and reconnect mains power, then power on the system and verify normal operation and stable voltages in BIOS or with appropriate diagnostic tools.

Recommendations

Use this power supply only in HP systems specified for small form factor units. Verify connector compatibility and physical fit for your chassis before purchase. If the system continues to show instability after replacement, check other components such as battery, memory and storage devices, and consult HP service documentation or an authorized technician for further diagnostics.
