Turn off the computer and any external devices, and disconnect the power cord from the power outlet. 2. Remove the chassis access panel. 3. Locate the jumper labeled E69. 4. Remove the blue CMOS jumper from pins 4 and 6 and put the jumper on pins 2 and 4. This clears CMOS. 5. Put the jumper back on pins 4 and 6. 6. Replace the chassis access panel and reconnect the power cord. Turn on the computer and allow it to start.

A warning message is displayed along with a series of long beeps for five seconds, then the system shuts down. Red Power LED 5 flashes five times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Red Power LED 6 flashes six times, once every second, followed by a two second pause. Beeps stop after fifth iteration but LEDs continue until problem is solved. Possible Cause Computer on. Computer in Suspend to RAM mode or normal Suspend mode. Processor thermal protection activated: A fan may be blocked or not turning. OR The heatsink/fan assembly is not properly attached to the processor. Pre-video memory error. Pre-video graphics error. Recommended Action None None required. Press any key or move the mouse to wake the computer. 1. Ensure the computer air vents are not blocked and the processor colling fan is running. 2. Open hood, press power button, and see if the processor fan spins. If the processor fan is not spinning, make sure the fan's cable is plugged onto the system board header. Ensure the fan is fully/properly seated and installed. 3. If fan is plugged in and seated properly, but is not spinning, then replace processor fan. 4. Reseat processor heatsink and verify that the fan assembly is properly attached. 5. Contact an authorized reseller or service provider. CAUTION: To avoid damage to the DIMMs or the system board, you must unplug the computer power cord before attempting to reseat, install, or remove a DIMM module. 1. Reseat DIMMs. 2. Replace DIMMs one at a time to isolate the faulty module. 3. Replace third-party memory with HP memory. 4. Replace the system board. For systems with a graphics card: 1. Reseat the graphics card. 2. Replace the graphics card. 3. Replace the system board. For systems with integrated graphics, replace the system board. dx2810/dx2818 Illustrated Parts & Service Map, MT chassis 516944-003 page 2
