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. Open the access panel and ensure that all power connections (20-
pin Main, 4-pin CPU) are secure on the system board.
2. Check if a device is causing the problem by removing all attached
devices (such as hard, diskette, or optical disk 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.
Red Power LED blinks five
times, once every second,
followed by a two-second
pause. Five beeps.
Pre-video memory error 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.
Red Power LED blinks six
times, once every second,
followed by a two-second
pause. Six beeps.
Pre-video graphics error. 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 the graphics card.
2. Verify the graphics auxiliary power cable is connected (if
applicable).
3. Insert the graphics card into another available slot.
4. The problem might be on the graphics card. Contact HP for
assistance.
Red Power LED blinks seven
times, once every second,
followed by a two- second
pause. Seven beeps.
System board failure (ROM
detected failure prior to
video).
1. Clear CMOS.
NOTE: Refer to the
