Question about HP Pavilion dv2000 Series Laptop Full Featured Intel Chipset Motherboard P/N: 417035-0...
Hello, I came across this page accidentally by searching the web and wonder if I can get an advice :)
Here's my problem: I have a HP Pavilion DV2000 (Intel Core Duo) with ''standard'' motherboard problem: not so long ago started turning off because of overheating (checked linux logs which said something like CPU temperature reached 100C, system shutting down). I realized that the problem is quite serious, but at that time I couldn't take some time to disassemble it and replace the thermal grease due to exams (however, I did that later, but it was too late, apparently...).
Now it boots until a certain point and then hangs, when Ubuntu is supposed to load X. Screen stays always black, with backlight. Everything seems to be working apart graphics: neither laptop screen nor external monitor show any signs.
I've read a lot of messages with people complaining about black screen, no boot and N beeps in HP models, but in my case system actually boots (I can see that because of HDD LED is showing some activity, speakers are working and I can enter a linux command, such as ''reboot'', which actually reboots the system), and doesn't beep at all.
So my question - is it a problem related to bad contacts between motherboard and NVidea chip or is it something else?
I'm about to sell that laptop as ''spares or repair'', as I guess it isn't worth fixing it. What do you thing?
Looking forward to your reply,
The issue is usually caused by broken solder connections between some chips of the logic board and the PCB surface itself. There are two ways to fix this problem. If you'd rather not do it yourself, you can have a third party laptop repair service do it for you but if you do prefer to do it yourself, you can reflow the GPU (repairs the solder connections) or replace the logic board alltogether. If you want to replace it, get the part and ebay and use a Laptop repair guide that teaches you how to install the part yourself. If you want to reflow, Google how to reflow a motherboard and you will find ways to re-heat the board to repair the solder connections, chances of success of DIY reflow are around 50%.

First off the thermal "grease" is not the problem unless you have been removing the cpu constantly. the problem is either
1 the fan has failed you need a new one.
2 the fan cooling fins are clogged with dust and goop, and has not been cleaned.
however at this point you could have either damaged the cpu, or damaged the main board components around the cpu area 100 c is hot (212 F ) we all know when water boils right?
so you can try to find a replacement cpu on Ebay its easy and faster then working with customer service.
