1 long 2 short means video fault.
Video is integrated to motherboard, so faulty motherboard.

It's a genuine HP manufacturing fault.

HP have extended warranty for DV2, DV6 and DV9 series laptops with AMD processors, so call to HP, get them to collect laptop - they will replace motherboard for free and will send you back working laptop.

And even if your part number not listed there they will fix it anyway.

So don't waste your time and call them now.

Hello worded,

My PC wont boot and its beeping??



From http://www.computerhope.com/beep.htm

 The computer POST (Power On Self Test) which tests the computer insuring that it meets the necessary system requirements before booting up. If the computer fails the POST the computer then returns a beep code indicating what is causing the computer not to post the POST. Generally if the computer POSTs properly you will receive a single beep (with some computer BIOS manufacturers it may beep twice).


THE POST TEST

     Each time the computer boots up the computer must past the POST. The following is the procedure of the POST:

1.  The first step of POST is the testing of the Power Supply to ensure that it is turned on and that it releases its reset signal.
2. CPU must exit the reset status mode and thereafter be able to execute instructions.
3. BIOS must be have readable.
4. BIOS checksum must be valid, meaning that it must be readable.
5. CMOS be accessible for reading.
6. CMOS checksum must be valid, meaning that it must be readable.
7. CPU must be able to read all forms of memory such as the memory controller, memory bus, and memory module.
8. The first 64KB of memory must be operational and have the capability to be read and written to and from, and capable of containing the POST code.
9. I/O bus / controller must be accessible.
10.  I/O bus must be able to write / read from the video subsystem and be able to read all video RAM..  

If the computer does not pass any of the above tests your computer will receive an irregular POST. An irregular POST is a beep code which is different from the standard which can be either no beeps at all or a combination of different beeps indicating what is causing the computer not to past the POST.


YOU NEED TO KNOW THE MAKE OF YOUR BIOS, SEE YOUR MOTHERBOARD HANDBOOK OR LOOK ON THE CHIP

POST TROUBLE SHOOTING

During the computers boot process the computer performs a POST which is a test that is performed each time a PC computer is boot up. If the computer passes you will receive a normal post which in most cases is the computer beeping one or two times. However in some cases you may receive a no POST or an irregular post indicating something is causing the computer not to pass the test. Below is a listing of some of the general steps that can be performed in helping the computer pass the POST sequence.

Precaution: Some of the following steps recommend removing physical parts within the computer. While within the computer it is highly recommend that you be aware of ESD and it's potential hazards.

First if any added hardware has been added to the computer before the irregular POST we would recommend it be removed to see if it is causing this issue.
Remove everything from the back of the computer except the power cable.
If you are receiving a sequence of beeps see if those sequence of beeps are listed within this page and follow the recommended steps for that beep code. If however your computers BIOS is not listed on this page or you are not sure which BIOS you have within your computer continue with the below steps.
Disconnect the IDE cables from the CD-ROM, Hard Drive, and Floppy drive from the Motherboard. If this resolves your irregular post attempt to connect each device one at a time to determine which device and or cable is causing the issue.
If the above still has not resolved the irregular post attempt to disconnect the Riser board (if possible) with all devices attached to it. If your computer does not include a riser board (ATX Motherboard) disconnect all the cards within the computer. If this resolves the issue or allows the computer to post connect one card at a time until you determine which card is causing the issue.
If you continue to receive the same problem with all the above hardware still removed attempt to disconnect the CPU and RAM from the Motherboard. If this fixes the issue connect the RAM if the computer still continues to work connect the CPU. Extra Note: If your computer has a Pentium II or Pentium III socket, once the CPU is remove you may receive a NO POST (No beeps). However it is a good recommendation to at least reseat the CPU.
If the issue persists its a good possibility that the motherboard is bad.
Note: Cache is normally not a consideration considering that the Cache controller is usually enabled after the POST, however this can differ.

Aliokas: correct

Customer had a new mobo and lcd replaced for the same reason approx 9 months ago when it was out of warranty.

I wonder if they will replace mobo again?

AliokasCommented:
Probably yes if you will talk with anger, knowledge and disappointment in voice.
I have sent one laptop three times every 3-6 months - fixed.
Thats their fault and they know it (even when they replacing motherboard - they know that it is possible that motherboard will fail again.

I'm sending them every laptop - no matter is listed in web site or not.

In fact, in most of these cases, the problem is with the solder connection of the graphics card mounted on the motherboard. some people suggest to use a heat gun to heat the graphics card and reestablish soldering.

Or try this:
1) put the laptop on a bed or a similar surface to close the air openings below
2) wait some time (30 min or 1hour) and let it get warm enough
3) restart.

There is no guarantee for this, but probably worked for many people.
Hope it works for you too..

Cheers for the suggestion.  I still have it sitting in a box waiting to be cannibalised for parts.
Sweet if that worked.

I tried this for HP Pavillion dv6000 series and it works.
Close all open air openings. I used thick blanket for this.
Open laptop and let it get warm enough app. 2 hours.
Then pressed Power button 3 seconds. Close laptop.

Then press again Power button and it works.
