Re: DV9000Z beep codes
1 long, 2 short on the HP DV9000 is "bad video adapter". Since your video card is integrated into your motherboard, you're looking at replacing the entire board (between $200-$400 on average) + labor costs. It would be more cost effective to purchase a new laptop for $100-$200 more, with full warranty.
Hope this helps, and remember to rate those that offer free help :)

- Stop Overclocking your CPU.
- Make sure your Heat Sink is placed properly above the processor.
- Clean the Processor fan, Heat Sink and other peripherals.
- Use High Speed fans.
- Use CPU Heat Sink Paste in the processor.
- Fix OS registry with reliable program like I always use Reginout.
- Shut down your computer atleast two hour a day.
Did you disassemble the heat-sink and processor? If you did, did you replace the thermal paste before putting back the heat-sink? did you make sure that the heat-sink touches and locks properly with the processor?
These are the things you need to check if it shuts down within 2 sec without any beep codes. This is a system built-in protection for the processor to avoid being burnt from overheat.
You might also want to check for any non-functioning fans and anything that can relate to "heat problems".
Hope this helps.
if you are in Toronto-Canada -- will perform this procedure for you , minimal cost
or let someone do this for you, who is familiar
its a heat sink (or lack thereof) issue with the CPU and video chip on board -- there is too much heat disspiated and not enough copper exposure to the video chip to absorb that amount of heat generated
before you do this let the computer cool down first for 30-60 minutes
one good thing to do , easy .. remove the screws from the plastic back cover, and remove the heatsink fan .. apply thermal compound grease to the heatsink (that sits on the CPU) and gently place it back -- do not put too much thermal compound, just a circular amount around the heat sink ..place it back, put all screws back
Any beeping if there is
CPU cooling fans seized of about to seize?
This should happen in 30 second for a thermo shutdown.
Reseat the cpu make sure there is thermo white compound between the heat sink and Top of the CPU
make sure there is proper flat seatin of the heat sink and CPU make sure the fan is working.
That beeping noise may be due to over heating. Most machines today have a temperature setting that will turn the machine off once the temperature reaches a certain point. Safety feature to avoid damaging your cpu and components. The shut down and restarting allows the CPU to cool down briefly. Thus allowing you to start the machine again. Usually it will shut down again once the temperature threshold is again reached. Good test is let the machine sit for 30 min. If it immediately starts up and shuts down a few minutes later. Heat build is usually the problem.
Typically this is due to heat sink or Fan on the computer CPU. Check to be sure both are connected to the CPU and functioning. If you have a fan on top of the heat sink above the CPU. Make sure it is working correctly. Dust build up over time will eventually kill the fan bearings or reduce airflow. Heat sink can and will become clogged with dust also. Replacement fans are easy to find. Heat sinks are even easier to clean. Depending on your machine and CPU position replacing the fan can be a challenge. But can be done in a few minutes with minimum tools.
Each bios has different post codes and it is difficult to tell what is happening with out knowing the bios of your particular machine. Listen for the beeps and check your computer manual. You can also google for this. Here is a web site that lists a few bios P.O.S.T codes. http://www.computerhope.com/beep.htm Once you know the beep sequence you can look it up. Usually points to the problem and you can go from there.
I assume you have a desktop computer. It is either the CPU is overheating or the 'Power Supply" is overheating/failing. Put your hand at the top back of your computer where the power supply is to feel if the fan is blowing air out the back. If there is no air coming out the back, then I think the fan has failed and the power supply overheats and fails. Repair or replace the fan before the power supply totally fails and has to be replaced.
Also check the fan and heat sink on the CPU. If they are loaded down with dust, the CPU is not getting cool enough, With power OFF, remove the fan and heat sink, clen them and put them back. That will do wonders to cool the CPU.
The sequence of one long beep and two short beep when starting computer usually means problem in your display adapter. Make sure your VGA connector is connected properly to VGA out port.
If you are using VGA card (non on-board), you might want to make sure that the card is inserted properly to motherboard.
The beep indicates that system can not initialize display.
