This is a problem with the hp dv9xxx/6xxx/2xxx series and compaq v6xxx/3xxx series too. There was a recall on them and hp will repair them for for free even if the warranty is up. I have heard it is an easy fix from someone but he won't tell me how to do it. On the dv and v series first the wifi card stops working and then it will not boot and only the led lights come on. Could this point to some kind of chip on the board that would direct power to the components? I know solder joints can go bad.

OK. Its an amd turion laptop with a sis chipset. There is nothing wrong with the motherboard. The problem is in the chipset. The flashes mean that some of the solder balls under the sis chipset is damaged. The solution is very simple. If you have a hot air gun or a simle home hair dryer you can fix it.

first take the laptop apart all the way to the bare motherboard.
locate the main chipset.
take a piece of aluminium tin foil and wrap the motherboard - it helps dispence the heat.
take a knife and cut out the tin foil in a square where the chipset is located.
take the hair dryer or if you have a hot air gun set it to 330 degrees celzius and air flow to 5.
heat the chipset for about 3 minutes making slow passes over the chipset.
do not hold the air gun on one place long because you will damage the chipset.
after heating it let it air cool for about 10-15 minutes.
Plug everything back in and turn on the laptop. it should work just fine.
if you get the same problem again repeat the procedure.
For better thermal conductivity be sure to apply thermal paste on the cpu the main chipset and the vga chipset.

THIS IS A RULE FOR ALMOST ALL LAPTOPS THAT HAVE A AMD TURION CPU, SIS CHIPSET AND AN NVIDIA VGA. IF YOUR LAPTOP TURNS ON BUT THERE IS NO PICTURE THIS IS ALSO THE SOLUTION ONLY APPLIED TO THE VGA CHIPSET - NVIDIA OR ATI OR SIS.

HOPE THIS HELPS.

Please don't put somebody thru wrong by copy this bunch of buls*its. This is perfect solution to kill your mainboard. I see in my lab many machines "fixed" this way.

ramjimh- Nvidia chipset need to be replace with brand new part with data code +09. Even reballing will not help in your case. You have NF-G6150-N-A2

This heat gun and hair dryer methods might work sometimes. It is taking a chance bacause the uneven heat might kill the main board. The correct way to fix the BGA chip is to use the BGA rework station. I had the same problem with my laptop 2 years ago. I sent my laptop to a place in California for repair. This place has the equipment. The laptop is still running fine at this time. I can't remember this company name. Its web site is www.alllaptoprepair.com. You also can get a free laptop troublshooting and repair guide from this comapny if you want to do it yourself.

Probably the usual NVIDIA chipset failure that HP is refusing to acknowledge in the TX1000/TX2000 notebooks for some reason (the TX2500 uses ATI). See here:
"http://h10025.www1.hp.com/ewfrf/wc/g...en&lc=en&cc=us"
There seems to have been a spike in such failures recently. Tell HP that your notebook has the same defective NVIDIA chipset that the dv2000/dv6000/dv9000 enhanced warranty covers and ask why your tx1000 isn't included?
Of course it could be something different, like a broken power jack and a nearly depleted battery. I'd bet on a fried NVIDIA northbridge.
