Have i messed up any chance of extended warrenty by removing motherboard?

DV9000 series, when you press the power, the lights blink ad then it powers off. So i dissembled it ad removed the motherboard to have a look, the 1 year warrenty had expired.

Now it seems this is a common problem with this series and seems to always point to a bad motherboard, bad chipset or graphics on the board.

Now it will be obvious i had opened it up as i removed a cable that was taped to the board. If there is an extended warrenty for this problem am i screwed?

Maybe they would just send a new motherboard? I am in the UK btw.

 

HP stopped the recall on certain models with faulty nvidia chips back last fall.

 

You could bake the motherboard in the oven, it may fix the problem temporarily.

I overheated* my old dead dv9000 on tuesday, managed it to boot into windows again. Then I ran 3dmark loop until laptop turned itself off = wlan came alive. I believe it will break soon again but did it for fun

The real fix is of course to replace motherboard. Since yours is now already taken out, look for the part number and check eBay for replacement. For my dv9014 they seem to cost around 150USD, not too bad.

* overheating trick I read on another forum lately: just put laptop in a plastic bag and wrap it in a towel, put it running on table upside down. That requires naturally that laptop will stay on by itself.

 

Overheating the laptop could damage something else. It's the same as the RRoD "fix" on the XBox 360 involving shutting all vents and letting the console fry itself - not gonna work.

Bake it (7 minutes at 210C did it for me on a DV9000 with a GeForce Go6150, not mine), or heat the nVidia chip with a hot air gun. If you decide to bake it, remove everything removable (including heatsink and CPU) cover everything except the nVidia chip with aluminum foil, and put 4 foil balls under the board so it doesn't touch the cooking tray. Now watch the clock.

Then pull the tray carefully and let it cool down for at least 30 minutes - any bump while the solder is still liquid will send chips flying.

While you're at it, do the copper shim mod for the GPU. It'll decrease the chances of it going bad again.

 

MB replacements on the eBay isn't that expensive. I replaced my tx1000z and dv2138xx without any problems. HP always denies the GPU overheating problems when you call them even though it's common knowledge in the computing world.
