Dead screen dv9500t w/nvidia geforce 8600 gs

I'm 10 days passed my 1 year and my screen is dead. The PC boots but the screen is just dead. Sometimes I get vertical colored lines, the screen may come on if the PC is on for a few hours, therefore I think its a video card issue and not the screen. I don't even get the initial HP boot screen.

Anybody else with this issue?

Does anybody know if the video card is onboard?

 

Can you hook your laptop up to an external monitor to make sure it's not the screen?
Also it might be worth re-installing the OS if you have recovery discs before sending it for repairs.

The 8600m GS is a dedicated video card.

 

Try an external monitor like Willy S said, then read this:

Odds are your NVIDIA GPU is fried. HP will replace the motherboard for free... slowly. They've had my dv2000 for over a month now.

 

Yep, its pretty well known that nvidia had a jacked up process whereby their cards would fry at temps hitting 70c. Warrantees have been extended for gpu failures since its basically a manufacturing defect. Just be glad it fried this year instead of year three since I don't think they would cover you after 2 years.

 

Did HP extend the warrantee for dv6500t laptops with the 8400M GS?

 

They should have. Check the list I linked to.

 

GPU is dead, but if you have an Intel processor they will fight you on replacing it. AMD agreed to pay for half the cost of replacement so HP only listed those machines for extended warranty replacement. Trying to claim that systems with intel processors are not affected (shyeah right).

 

I didn't see the dv6500t listed there. It only went up to dv64xx. I was hoping the warrantee on the dv6500t would be extended since it has the 8400m GS. The strange thing is that most of the models listed on the page you linked to probably have even older (pre 8-series) Nvidia cards.

 

Call HP and see what they say. Your chip has the exact same defect as the notebooks that are covered.

 

Yes I do get a picture when I hook up an external monitor.

So does this mean that the GPU is fine?

If I leave the notebook open, after about 30 mins the screen just comes up!

This is driving me nuts

 

No it's dead. Since you're going to need to replace the mobo why not ask what options you have, like a different GPU or a better one.
Would be interesting to know, because some companies stopped using Nvidia there must be compatible mobo's out there with ATI cards or maybe not?

 

Maybe not, can you try re-installing the os?
What happens when you try to boot into safe mode?

 

This is NOT an OS issue guys, when its not working I dont' even get the "HP boot screen", which means what ever the issue, its happening BEFORE the OS even loads.

My notebook which is a dv9500 is not even on that list.

 

I had a similar problem several times with an old laptop, intel integrated gpu. I used a norton restore software which gives you the option to restore your computer before the os loads up. Fixed the problem some of the time, not others, but the lappy is still chugging away to this very day

You're problem could be software(virus maybe) or it could be a loose wire\cable. It might be worth checking your monitor cable which should be under the section just above your keyboard, very easy to access but you should still follow a guide for your, or a similar, laptop to do it.

 

Tough one. Thermal expansion could be causing an intermittent contact to connect after 30 minutes? It could be in the GPU, in which case the problem will eventually get worse and you'll need a new motherboard. Reseating the internal video cable where it connects to the motherboard might help. It doesn't sound like a software problem to me but you could try booting a MemTest86+ CD just to make absolutely sure.
