Frequency of dv6000z system board failures

I have just had my system board replaced for the second time in less than two years. I have an AMD Turion 64 processor. Does anyone know how common these failures are and what the problem is? Has HP fixed the problem in system board design?

The response from HP this time was very quick. But should I expect to have it happen again?

 

was it due to over heating?

 

It failed to turn on one morning and gave three beeps -- one long and two short. It had been running hot to the touch, but is now running much cooler. HP also replaced the thermal pad. I started using a cooler pad two months ago.

 

My DV9000 with an AMD processor just gave me the exact same beep code. It is making its fourth trip back to HP.

According to Consumerist, there may be a class-action lawsuit against HP over these models. I plan to join it.

 

Thanks for the info. Does anybody know just how big this problem is? Is it just dual core AMD processors, all AMD processors, AMD and Intel processors? Does HP have a reliable fix for the problem(s)? It would help if an HP rep could give us some idea of the size of the problem and what they are doing about it. It would be good for HP's long term consumer relations and market viability.

 

I believe it's a problem with only AMD processors, and it happened to a lot of the older models (dv X000z, dv X500z).

 

It happens more frequently with the AMD models, due to the hotter-running NVIDIA chipsets, but not exclusively. Inadequate cooling design on both model lines, which was fixed by a BIOS update that keeps the fan running 24x7. Unfortunately most people don't even know what a BIOS is so a lot of systems get fried. Without the update, if the CPU doesn't heat up enough to start the cooling fan the rest of the notebook cooks. The 55C threshold HP set in their old BIOS revisions was way too high. No problem for the CPU, bad for everything else.

FWIW, my dv9000z is still running cool and quiet. It has the updated BIOS.

The new dv4z/5z/7z and tx2500z notebooks use AMD chipsets built in TSMC's 55nm fabs so they might even run cooler than Intel chipsets despite having vastly more powerful integrated GPUs. The early reviews of the tx2500z are encouraging. See if you can talk HP into giving you a dv5z series machine as a replacement.

 

55c is way to high.....similar specs on the fujitsu A3210 has it set at 45c max...
It doesn't take a rocket scientist to see that fujitsu is a higher quality machine anyway, but some people don't like them because of their lack of independant graphic cards in most of their machines...but they are of high quality....
Fujitsu AMD machines have always ran cool, and quiet.
