Question about HP Pavilion dv9000z Notebook
You need to look On the Recall/Extended Service List To See If Your dv9000 Series Is Listed... Go To The Link I Post Below,
Flip Your Laptop Over And Look For Your P/N......
then look on the list from the link I posted and see if Your P/N is listed in the DV9200/DV9300 Section... If it is there... You can send it to them for a free repair/motherboard replacement.... You will first have to contact them either by Live Chat or by Telephone and explain your Symptoms and that you found your model listed under the extended service list of recalled laptops....
If your laptop is Not Listed there... You Do not need to replace the motherboard, You can Reflow the Graphics Chip... You have a Faulty Nvidia Graphics CHip That has failed due to thermal damage...
THis involves complete disassembly of the laptop, removal of the motherboard... You'll need to shield all areas around the video chip.. Use Folded up tin foil... You'll also need to put weight on top of the Video Chip... Use a stack of 8 Quarters and Center them in a stack on the video chip... You will need a Heat Gun...(google it)... They cost about $15 US.... You will need to cover all plastic ports and connectors near the video chip... cover the CPU, cover the RAM slots...(use the foil)....
Turn on the heat gun, Set it to LOW... Hold about 6 inches from the chip and rotate clockwise in circles around the outer edge of the video chip, then concentrate the heat gun on the stack of quarters holding the heat gun about 3 inches from the quarters..Hold for 30 seconds, continue to rotate around the outer edge of the chip, slowly moving the heat gun closer, then pulling it away... (go no closer than 2 inches away from the chip... the whole process takes 3 minutes.... Do not overheat the chip... it's better to underheat it ans to have to re-do the reflow...
The goal is to Remelt the Solder Ball Contacts on the underside of the chip to re-make contact with the contact pads on the motherboard...
Make sure when you are done with this process that you thouroughly Clean the Heatsink anf Fan assembly!! Very Important!! You need to make sure no dust/debris are blocking the heat sink Cooling Fins... And that the fan blades are as well dust/debris free....
Reassemble entire laptop and Power on....
