Accessing HP Insight Diagnostics The HP Insight Diagnostics u tility can be used to view information about the hardware configuration of the computer. It can also perform ha rdware diagnos tic testing on the comput er and its subsystems, which provides information for troub leshooting.
Improperly installed The DIMM is not seated properly or a DIMM socket is bad or unusable. Open the computer casing and reseat the DIMM. If this does not work, try different sockets. Check that no debris or corrosion is in the socket. Defect ive If the above remedies do not solve the DIMM issue, the DIMM could be defective.
Display "Default BIOS set tings have been loaded... Press F10 for Setup, F2 to Continue”. If the user selects F10 , proceed to Setup. However, if the user selects F2 , the BIOS should proceed to ste p 2 below. For all other SKUs, Use F1 instead of F10 in the above handling.
● Run tests on the hard drive ● Establish a supervisor password that controls acce ss to the Setup Utility BIOS Updates HP periodica lly releases system BIOS up dates, whi ch are available from th e HP website. These updates often contain fixes for known issues in the BIOS.
6. Remove the jumper from pins 2-3 pins and put it on pins 1-2 to clear CMOS. Keep the cap on pins 1-2 for 5 to 10 second s. 7. Replace the jumper on pins 2-3. 8. Reinstall the battery. 9. Replace the access pane l, external equi pmen t, and reconnect the power cord.
C Troubleshooting Without Diagnostics This chapter provide s information on how to i dentify and correct minor prob lems, such as hard drive, optical drive, graphics, audio , memory, and softwa re problems. If you encounter p roblems with the computer, refer to the tables in this chapte r for probable causes and re commended solutions.
● Refer to the comprehensive online tech nical support at http://www.hp.com/ support . ● Refer to Helpful Hints on pa ge 73 in this guide. To assist you in reso lving problems online , HP Instant Supp ort Professional Ed ition provides you w ith self-solve di agnostics.
● Be sure that all the neede d device drivers have been installe d. For example, if yo u are using a printer, you need a dri ver for that model printer.
Poor performance is experienced. Cause Solution Processor is hot. 1. Make sure airflow to the computer is n ot blocked. Leave a 10.2-cm (4-inch) clearance on all vented sides of the computer and above the monitor to permit the requ ired airflow. 2. Make sure fans are connected and wor king properly (some fans only operate when needed).
The computer will not turn on. Cause Solution Drive data or power supply cables might not be properly connected. Reseat drive data and power supp ly cables. The unit temperature might have excee ded safe limits, or the fan might be blocked. The computer is in an exceedingly h ot environment.
Solving Media Card Reader Problems NOTE: It is possible that the driver your memory card uses has become corrupted or is not functioning cor rectly. From time to time new d r ivers and firmware are rel eased to address issues. New firmware for your memory card reader might be available that wo uld resolve the part icular issue you are having.
Memory card appears in My Computer, but errors occur when writing or reading. Cause Solution You are using an adapter for a type of memory card not supported by the reader.
High pitched nois e coming from inside a flat panel monitor. Cause Solution Brightness and/or contrast settings are too hi gh. Lower brightness and/or contr ast settings. Solving Audio Problems If the computer ha s audio features a nd you enco unter audio problems, see the common cau ses and solutions listed in the foll owing table.
No response from the USB keyboard a nd mouse during running of application. Cause Solution The application has stopped r esponding. Restart the compu ter. Mouse does not respond to movement or is too slow. Cause Solution Mouse connector is not properly plu gged into the back of the computer.
Diagnostics reports a failure. Cause Solution Network controller interrupt is shared w ith an expansion board. Under the Computer Setup Advanced menu, change the resource settings for the board. C heck that they are different from those of the network controller.
Memory count during PO ST is wrong. Cause Solution The memory modules may not be installe d correctly. Check that the memory modules have been installed correctly and that proper modules are used. One of the memory modules might be faulty. 1. Find out which module is f aulty by bo oting with each module individually.
An optical drive cannot read a CD or DVD disc. Cause Solution CD or DVD disc is dirty. Clean the disc. Windows does not detect the DVD-ROM d rive. 1. Use Device Manager to remove or uninstall the de vice. 2. Restart the computer and let Windows detect the device.
