Activity Possible cause Red Power LED blinks five times, once every second, followed by a two-second pause. Five beeps. Pre-video memory error. Red Power LED blinks six times, once every second, followed by a two-second pause. Six beeps. Pre-video graphics error. Red Power LED blinks eight times, once every second, then stops blinking. Entering FailSafe (BootBlock) Recovery Mode System does not power-on and LEDs are not blinking. No beeps. System unable to power on. Recommended action 2. Check if a device is causing the problem by removing all attached devices (such as hard, diskette, or optical drives, and expansion cards.) Power on the computer. If the system enters the POST, power off and replace one device at a time; repeat this procedure until failure occurs. Replace the device that is causing the failure. Continue adding devices one at a time to ensure all devices are functioning properly. 3. Check power supply functionality: a. Disconnect AC power b. Remove all internal power supply cables from the system board. c. Plug in AC power. - If the power supply fan spins and the LED lights, then the power supply is good. Replace the system board. - If the power supply fan does not spin or the LED does not light, replace the power supply. CAUTION: Internal components might be powered even when the computer is off. To prevent damage, disconnect the computer power cord before you remove a component. 1. Reseat DIMMs. 2. Replace DIMMs one at a time to isolate faulty module. 3. Replace third-party memory with HP memory. 4. The problem might be on the system board. Contact HP for assistance. CAUTION: Internal components might be powered even when the computer is off. To prevent damage, disconnect the computer power cord before you remove a component. (BIOS did not detect a VGA-compatible device) For systems with integrated graphics, the problem might be the system board. Contact HP for assistance. For systems with graphic cards: 1. Reseat the graphics card. 2. The problem might be the graphics card. 3. The problem might be the system board. Contact HP for assistance. Either FailSafe detected a corrupted ROM, or the user pressed Esc before powering on. The BIOS does not halt at this point, but attempts to boot to a ROMPaq floppy or CD-ROM (USB devices are not supported). 1. Reflash ROM with a ROMPaq floppy or CD-ROM. 2. The problem might be in the system board. Contact HP for assistance. CAUTION: Internal components might be powered even when the computer is off.
