Activity Possible cause Recommended action
Red Power LED blinks
four times, once every
second, followed by a
two-second pause. Four
beeps.
Power failure (power
supply is overloaded).
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 make sure that all power
connections 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.) Turn 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 make sure that 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. Confirm the graphics card is in the appropriate slot (PCIe
x16).
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
Maintenance and Service Guide for
the computer model for detailed information on clearing
CMOS.
2. The problem might be on the system board. Contact HP for
assistance.
Red Power LED blinks
eight times, once every
second, followed by a
two-second pause. Eight
beeps.
Invalid ROM based on
bad checksum.
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. Clear CMOS.
NOTE: Refer to the
Maintenance and Service Guide for
the computer model for detailed information on clearing
CMOS.
2. Upgrade the ROM using SoftPaq, either from the hard
drive, CD, diskette, or USB removable device (for example,
HP Drive Key). See the ROM Flash section of the
Maintenance and Service Guide at http://www.hp.com/
