The HP Mini-in-One 24 model is a versatile display designed for integration with HP Desktop Mini PCs, offering a comprehensive solution for various computing environments. This device serves as a monitor and a docking station, providing a streamlined setup for users.
The primary function of the HP Mini-in-One 24 is to act as a display for a connected computer, specifically designed to house and integrate an HP Desktop Mini PC within its rear compartment. This integration allows for a single power-on experience for both the display and the Mini PC, simplifying operation and reducing cable clutter. The monitor supports a 35W or 65W HP Desktop Mini, creating a fully enclosed and compact workstation.
Beyond its display capabilities, the device functions as a connectivity hub. It features a USB Type-C connector for interfacing with an HP Desktop Mini, enabling data transfer and potentially power delivery. Additionally, it includes multiple USB 3.1 Gen1 ports (four on the rear and two on the side) for connecting various USB devices, an audio-out (headset) jack on the side for personal audio, and a USB Type-B upstream port to connect the display's USB hub to a source device. A DisplayPort video input is also available for connecting other video sources.
The integrated 1080p HD webcam with dual-array microphones allows for video conferencing and communication. The monitor also incorporates 2.5W stereo internal speakers for audio output. For security, a security cable slot is provided on the rear for an optional security cable.
The HP Mini-in-One 24 offers a range of features designed to enhance user experience and adaptability. The display boasts a 60.5 cm (23.8-inch) diagonal viewable screen area with a 1920 × 1080 resolution, providing clear and crisp visuals. It also supports lower resolutions with full-screen capability. The nonglare panel with an LED backlight ensures comfortable viewing in various lighting conditions, while wide viewing angles allow for clear visibility from different sitting or standing positions.
Ergonomic adjustments are a key aspect of its design, with tilt, swivel, height, and pivot adjustment capabilities, enabling users to customize the display's position for optimal comfort and productivity. The removable stand offers flexibility for alternative mounting solutions, such as attaching the display to a wall mount device or swing arm using its VESA® mounting capability.
User interaction is facilitated through an intuitive on-screen display (OSD) menu, available in several languages, for easy setup and screen optimization. The OSD allows for adjustments such as brightness and color settings. Dedicated buttons on the rear of the monitor provide quick access to OSD functions, including a back button to exit or return to previous menu levels, plus and minus buttons for navigation and adjustment, and a Menu/OK button to open the OSD or select items. A master power switch on the rear allows for turning off all power to the display.
The monitor supports Plug and Play functionality, simplifying setup with compatible operating systems. It also features a Power Saver mode to meet requirements for reduced power consumption, contributing to energy efficiency. The integrated webcam includes a physical shutter for privacy, allowing users to open or close the webcam as needed.
The HP Mini-in-One 24 is designed with serviceability in mind, providing detailed procedures for maintenance and repair. The device is categorized into two levels of service: Level 1 for cosmetic/appearance/alignment service and Level 2 for circuit board or standard parts replacement. This structured approach ensures that repairs can be performed efficiently.
The service guide emphasizes important safety information and precautions, stressing that only trained service personnel familiar with the product should perform maintenance. It highlights the necessity of disconnecting the power cord before opening the monitor to prevent component damage and advises on following ESD safety procedures when handling electrical components.
For component replacement, the guide provides an illustrated parts catalog, detailing major components such as the mid-frame, deco bezel, panels, VESA mount, main chassis, scalar board, speakers, PCB brackets, IO shielding, bucket, vent cover, VESA cover, webcam module, side USB PCBA, and function PCBA. It also includes instructions on how to order spare parts, specifying distributors for various connectors and providing links to HP's part store for cables and other components.
Detailed removal and replacement procedures are outlined for various parts, starting with preparation for disassembly, which includes cleaning the work area, identifying the disassembly area, and ensuring the availability of necessary tools like press fixtures, screwdrivers, knives, gloves, cleaning cloths, ESD protection, and a scraper bar. Specific steps are provided for removing the rear case, splitting the middle frame, removing the IO shielding, small boards, webcam module, die casting, cables, and the PCBA. Instructions also cover the removal of speakers and the chassis/middle frame.
Connector repair procedures are extensively covered for DisplayPort, DC jack, headphone, USB-C, USB upstream, and USB A connectors. These procedures involve using a hot air gun to melt solder, lifting the old connector, placing a new component, and soldering it, with an emphasis on matching the PCB footprint and polarity for capacitors. The guide also specifies the use of lead-free solder wire to meet ROHS requirements.
After any repair, a function test is recommended to confirm that all functions are working correctly. This includes testing USB-C, DisplayPort, audio, and standard USB connections to ensure proper image display, sound playback, data transmission, and volume control. The guide also provides a troubleshooting section with common problems, possible causes, and recommended solutions, such as connecting the power cord for a blank screen or adjusting brightness for a blurred image.
