3 Routine care, SATA drive guidelines, and disassembly preparation This chapter provides general service information for the computer. Adherence to the procedures and precautions described in this chapter is essential for proper service. CAUTION: When the computer is plugged into an AC power source, voltage is always applied to the system board. You must disconnect the power cord from the power source before opening the computer to prevent system board or component damage.
Preventing electrostatic damage to equipment Many electronic components are sensitive to ESD. Circuitry design and structure determine the degree of sensitivity. The following packaging and grounding precautions are necessary to prevent damage to electric components and accessories. ● To avoid hand contact, transport products in static-safe containers such as tubes, bags, or boxes. ● Protect all electrostatic parts and assemblies with conductive or approved containers or packaging.
Recommended materials and equipment Materials and equipment that are recommended for use in preventing static electricity include: ● Antistatic tape ● Antistatic smocks, aprons, or sleeve protectors ● Conductive bins and other assembly or soldering aids ● Conductive foam ● Conductive tabletop workstations with ground cord of one-megohm +/- 10% resistance ● Static-dissipative table or floor mats with hard tie to ground ● Field service kits ● Static awareness labels ● Wrist straps and footwea
● Never cover the ventilation slots on the monitor with any type of material. ● Install or enable power management functions of the operating system or other software, including sleep states. Routine care General cleaning safety precautions 1. Never use solvents or flammable solutions to clean the computer. 2. Never immerse any parts in water or cleaning solutions; apply any liquids to a clean cloth and then use the cloth on the component. 3.
● If you remove a key, use a specially designed key puller to prevent damage to the keys. This tool is available through many electronic supply outlets. CAUTION: Never remove a wide leveled key (like the space bar) from the keyboard. If these keys are improperly removed or installed, the keyboard may not function properly. ● Cleaning under a key may be done with a swab moistened with isopropyl alcohol and squeezed out. Be careful not to wipe away lubricants necessary for proper key functions.
Screws The screws used in the computer are not interchangeable. They may have standard or metric threads and may be of different lengths. If an incorrect screw is used during the reassembly process, it can damage the unit. HP strongly recommends that all screws removed during disassembly be kept with the part that was removed, then returned to their proper locations. CAUTION: Metric screws have a black finish. U.S. screws have a silver finish and are used on hard drives only.
NOTE: Batteries, battery packs, and accumulators should not be disposed of together with the general household waste. In order to forward them to recycling or proper disposal, please use the public collection system or return them to HP, their authorized partners, or their agents. SATA hard drives Serial ATA Hard Drive Characteristics Number of pins/conductors in data cable 7/7 Number of pins in power cable 15 Maximum data cable length 39.
Cable management Always follow good cable management practices when working inside the computer. 16 ● Keep cables away from major heat sources like the heat sink. ● Do not jam cables on top of expansion cards or memory modules. Printed circuit cards like these are not designed to take excessive pressure on them. ● Keep cables clear of sliding or moveable parts to prevent them from being cut or crimped when the parts are moved. ● When folding a flat ribbon cable, never fold to a sharp crease.

If you encounter problems with the computer, refer to the tables in this chapter for probable causes and recommended solutions.
If it becomes necessary to call for technical assistance, be prepared to do the following to ensure that your service call is handled properly: ● Be in front of your computer when you call. ● Write down the computer serial number, product ID number, and monitor serial number before calling. ● Spend time troubleshooting the problem with the service technician. ● Remove any hardware that was recently added to your system. ● Remove any software that was recently installed.
● If you have installed an operating system other than the factory-installed operating system, check to be sure that it is supported on the system. ● If the system has multiple video sources (embedded, PCI, or PCI-Express adapters) installed (embedded video on some models only) and a single monitor, the monitor must be plugged into the monitor connector on the source selected as the primary VGA adapter.
Computer date and time display is incorrect. Cause Solution RTC (real-time clock) battery may need to be replaced. Reset the date and time under Control Panel (Computer Setup can also be used to update the RTC date and time). If the problem persists, replace the RTC battery. See the Removal and Replacement section for instructions on installing a new battery, or contact an authorized dealer or reseller for RTC battery replacement.
Poor performance. Cause Solution Processor is too hot. 1. Make sure airflow to the computer is not blocked. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the required airflow. 2. Make sure fans are connected and working properly (some fans only operate when needed). 3. Make sure the processor heat sink is installed properly. Hard drive is full. Transfer data from the hard drive to create more space on the hard drive. Low on memory.
Computer powered off automatically and the Power LED flashes red four times and then white two times. Cause Solution Processor thermal protection activated: 1. Ensure that the computer air vents are not blocked and the processor cooling fan is running. 2. Open the access panel, press the power button, and see if the processor fan (or other system fan) spins. If the fan does not spin, make sure the fan cable is plugged onto the system board header. 3. If fan a plugged in and not spinning, replace it.
Solving power problems Common causes and solutions for power problems are listed in the following table. Power supply shuts down intermittently. Cause Solution If equipped with a voltage selector, voltage selector switch on rear of computer chassis (some models) not switched to correct line voltage (115V or 230V). Select the proper AC voltage using the selector switch. Power supply will not turn on because of internal power supply fault. Replace the power supply.
Solving hard drive problems Hard drive error occurs. Cause Solution Hard disk has bad sectors or has failed. 1. In Windows 7, click Start, click Computer, and right-click on a drive. Select Properties, and then select the Tools tab. Under Error-checking click Check Now. In Windows 10, type file in the taskbar search box, and then select File Explorer from the list of applications. In the left column, expand This PC, right-click on a drive, select Properties, and then select the Tools tab.
Nonsystem disk/NTLDR missing message. Cause Solution The system is trying to start from the hard drive but the hard drive may have been damaged. ▲ Perform Drive Protection System (DPS) testing in system ROM. System files missing or not properly installed. 1. Insert bootable media and restart the computer. 2. Boot to the windows installation media and select the recovery option. If only a restore kit is available, then select the File Backup Program option, and then restore the system. 3.
Solving media card reader problems Media card will not work in a digital camera after formatting it in Windows. Cause Solution By default, Windows will format any media card with a capacity greater than 32MB with the FAT32 format. Some digital cameras use the FAT (FAT16 & FAT12) format and can not operate with a FAT32 formatted card. Either format the media card in the digital camera or select FAT file system to format the media card in a computer with Windows.
After installing the media card reader and booting to Windows, the reader and the inserted cards are not recognized by the computer. Cause Solution The operating system needs time to recognize the device if the reader was just installed into the computer and you are turning the PC on for the first time. Wait a few seconds so that the operating system can recognize the reader and the available ports, and then recognize the media inserted in the reader.
Blank screen (no video). Cause Solution To access Control Panel in Windows 7, click Start, and then select Control Panel. To access Control Panel in Windows 10, type control panel in the taskbar search box, and then select Control Panel from the list of applications. 2. Monitor is configured to use an input that is not active. Expand the Resolution box, and then use the sliding control to reset the resolution.
Monitor does not function properly when used with energy saver features. Cause Solution Monitor without energy saver capabilities is being used with energy saver features enabled. Disable monitor energy saver feature. Dim characters. Cause Solution The brightness and contrast controls are not set properly. Adjust the monitor brightness and contrast controls. Cables are not properly connected.
“No Connection, Check Signal Cable” displays on screen. Cause Solution Monitor video cable is disconnected. Connect the video cable between the monitor and computer. CAUTION: Ensure that the computer power is off while connecting the video cable. “Out of Range” displays on screen.
