Question about HP Compaq Business Desktop d330

Blinking red light at "on" button

I have an HP Compaq d330. Yesterday it worked but today the "on" button only produces red blinking lights instead of the usual green lights. The light on the right blinks 3 times over and over. The computer will not boot up or make any sounds. I'm afraid that it got zapped by lightening last night. Could a lightning strike in the area cause the computer to do this? Is all lost? Could it be possible to get my documents off it even if the computer itself is dead? Yikes!
Thanks so much!

Dont panic the date is more than likely fine was the computer off or on during the night. The three flashes is usual joined with 3 beeps chweck that the internal speaker is on. Second there is a small battery on the motherboard. Disconnect the power then take the battery out for twenty seconds then put it back in be gentle taking it in and out the reconnect the power then see if the unit boots if not. At worst you can take the hard drive out of the computer and put it in another and retrieve the data.
Hope this helps :-)

SOURCE: Blinking red light at

Please take a look at this link, and consider the possibility that your power supply has failed. Also helpful may be this article. If you take it in to them, a local computer tech can load test the power supply to determine if it is in fact at fault, and they are readily replaced for minimal cost.
Most likely your hard drive will have been spared, and your data secure, but this is the reason quality surge protectors are recommended for IT systems. No way to tell for sure until you power it up again and see if the hard drive spins up...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

My hp compaq doesn't work when i branche the cable of alimentation it signe with red


How many times does the red light come on ? It should blink a number of times, then go off for a little while, and start blinking again. The number of blinks within each cycle will help you find out what is wrong:
Number of 1-second red LED blinks followed by 2-second pause, then repeats:
2-processor thermal protection activated
3-processor not installed
4-power supply failure
5-memory error
6-video error
7-PCA failure (ROM detected failure prior to video)
8-invalid ROM, bootblock recover mode

Desktop turns off and a flashing red light appears


Sounds like you need to reseat the processor and heat sink, and use some good quality thermal paste.

If a reseat dosent do it, test the power supply, ocasionally they will be bad right out of the box, it is rare, but it happens.

Also check the MoBo connections, and make sure all fans are connected powered up and spinning, people often miss reconnecting something when swapping motherboards.

Hope this helps!!

Yellow light blinking next to blue on/off light


The "tin can" symbol below the yellow light signifies a hard disk. The yellow light is a hard disk activity indicator, it is nothing to worry about. It is just tell you that the computer is accessing the hard drive.

HP COMPAQ D530 RED BLINKING LIGHT WITH BEEPING SOUNDS.


4 beeps & 4 flashes mean problem with the power supply. For my experience, most of the time the PSU is good, it is just overloaded.

Red light flashing on power button


Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.
