Having problems with your HP Pavilion dv6000z Notebook ?

HP laptop display issue

\015 My HP Pavilion dv6045nr will not show any display when booted up. Screen remains completely black, not just dim. Error code is 1 long beep, followed by two short beeps. Information I've found elsewhere indicates that may be a problem with the RAM, but I've tried replacing it and it had no effect. It has two RAM slots and I've tried swapping the cards, as well as running off one at a time. Basically i covered every possible combination of RAM placement, but got the same error every time. It was working one night with no indications of trouble, but a few hours later when I woke up it seemed that it would not "wake up." When I tried rebooting, I got the error beeps and it hasn't had a display since. I have NOT tried an external monitor yet, I would have to find someone with a desktop and don't know anyone off hand. I appreciate any help anyone can give!\015

I was using a HP DV6910US and i faced a problem when my laptop froze and i had to press thepower button to reboot.
\015\012But on reboot my laptop had all the lights on keyboard light on with no dispaly on screen/blank.
\015\012I have called the HP helpline and they told me to do these steps...
\015\0121.Disconnect all cables and usb connections of the laptop including power cord.
\015\0122.Remove the Laptop Battery.
\015\0123.Do not connect the Power cord now,Instead press and hold the power button for 25 seconds.
\015\0124.Now connect the powercord and put the laptop battery in place.
\015\0125.Now press the power button on your laptop and as the lights come on immediately press the Function/fn repeatedly.
\015\012Your problem is now solved as the screen comes on to life.
\015\012I was told that the problem is something related to the memory of the battery.
\015\012I hope my answer will help many Hp owners to solve the simple problem.
\015\012If you cannot get through you need to call the HP Toll free helpline at your place.
Had the same problem. It is due to the graphics chip which cannot be reseated or removed as it is soldered directly to the mainboard. What's more is that the solder is between the bottom of the chip and the top of the motherboard so there's no way of getting to it to try and reflow etc. You could try a heat gun if you’re desperate but that would almost certainly end in the total death of it altogether as the surface mount resistors and wot-not start ice skating into another dimension!
\015\012I have just thought though that the chip resides under the heat sink it shares with the CPU. This is exactly the same as the Xbox 360 X-Clamp repair, being that the chip get's hot (which being an Nvidia - Big Fan! - it would) and then melts the solder and lifts from the PCB resulting in failure.
\015\012With the Xbox, removing the crappy inadequate X-Clamp that Microsoft fitted and bolting it straight through with decent bolts and some welly fixes it nine times out of ten. The only thing different is that with the Xbox I prefer to cool the CPU and fry the GPU for 15 minutes to reflow the joints. In this case that is not practically possible but as I said, just clamping the chip down often rectifies the fault.
\015\012Another interesting thing I have noticed about this is that the heat sink has five screws that fix it. This is interesting as it points to the fact that HP were aware of this problem from the start. Especially as the four screws that secure the CPU go straight through the PCB and into a steel bracket which gives it a good clamp but the fifth that secures the GPU screws into some naffy (definite afterthought) of a surface mounted ‘bolt pot’ with all the ‘clamp ability’ prospects that a flimsy PCB can offer! To add to that, in their wisdom HP decided that sticking some of that awful putty **** (loosely) between the two was enough to withdraw the heat thrown out by the Nvidia and transfer it to the sink!
\015\012My eight year old son could have done a better job than that!
\015\012Well I will rip it apart again later and see if I can lose the ‘bolt pot’ and screw straight through the PCB. I will also get some decent material to fill the gap and some thermal paste, I thinks. I will post the results once I have done it.
\015\012If anyone is going to attempt this then I will say that be careful if you drill the PCB as I am sure it has a middle ground plate.
\015\012Ah well, here we go again……
