DV9500 and Nvidia 8600M GS

Yikes, it went out that fast.....

 

Yeah, I waited 6 weeks for the repair and my fixed toy lasted a week. I'm not a happy bunny

 

I also face exactly the same problem with my hp dv9500t with a 8600M GS card. The computer hangs right after it shows the Vista progress bar and before the login screen appears. Also if I manage to login, it doesn't identify the graphics adapter as nVidia and it defaults to the Standard VGA adapter. Moreover if I manage to logon, it will log me in with the lowest bit depth and lowest resolution which looks horribly ugly - and I need to manually set the display resolution.

It is now a little less than 2 years that I bought this machine and it is now out of warranty!

This is really frustrating that HP and nVidia has taken all of us for a ride on such a high dollar purchase. It is simply cheating!! And now we can't even get the graphics card simply replaced as it is part of mother board and warranties expired. There should be some class action to be filed for cheating customers like this!

 

I also did a clean install with Vista 64 retail and then installed the nvidia driver - the driver still doesn't get identified in display properties.

I even installed xp 64 with corresponding nvidia driver - still the same problem.

I am now really frustrated, I can't make this machine sleep or hibernate as those options are now disabled. If I shutdown the machine and later start it, it won't start for 2-3 time, even if it starts it reboots. Finally, if I turn a bit lucky, it will boot into ugly looking low bit and low resolution, which I then have to manually change.

Also the nVidia 8600M GS adapter always shows with a yellow exclamation in the device driver list.

Looks like I need completely disable the nvidia driver, to even sensibly boot into my system.

I now regret why I went for a good configuration, if the machine were to fail on something like a graphics card which can't be replaced with replacing the whole mobo.

Any idea how much it costs to replace a notebook mother board for dv9500t? Or should I salvage the memory, harddisks for a new notebook?

 

Wow, it's weird when exactly the same thing happens to a bunch of computers.

Anyway...to answer your question: I took my laptop to get an estimate for the repairs in the UK, where I am at the moment, and they said it would be around £300-£400 and I would only have a 3 month warranty. I had read about others with the same problem who have gone for the change, and went through 3 motherboards within 6 months. Also, in the UK they can't bring parts for a laptop built for the US...i would have had to send it back to HP USA.

I don't know whether the money and time wasted are worth it for you...i decideed to put everything i have on an external drive, wipe the disks clean and sell it either whole or for parts.

 

Some days ago,I complained with HP for this situation,because I am a little afraid of mine...
Altough I still have 1year warranty if it goes wrong after that it is very bad..
What they told me is that now we can buy an 1 year warranty even after 1year of warranty (out of 2) at least that..

 

They still get money if you buy a new warranty. What they should be doing is fixing the problem for free

 

Guys, all nvidia g84/g86 chips including my 8600M GS are bad.

http://www.theinquirer.net/inquirer/news/703/1028703/nvidia-g84-g86-bad

Since we all are taken for a ride can't we file a class action suit against nVidia and HP who cheated us to the core, and robbed our hard earned dollars!

Looks like hp and other nVidia vendors were blindsided by nVidia with defective gpus. I hope sooner or latter this should snow ball into a huge issue and should result in a global recall.

I respect SONY for one thing - when their CCD chips were found defective in a huge number of video cameras they promptly issued a world wide recall and free replacement.

We deserve the same here. I need a notebook which could at lease be serviced, so that I can sell it off. I can't afford to keep this machine at home and lose my time and sanity on it and I can't buy a better one unless this is packed off!!

 

Hello All,

Since the frying nVidia GPU in HP machines is a general concern and HP is refusing to list all affected models in the extended service warranty (including my dv9500t), I urge you to mail Mark Hurd, the CEO of HP with your concerns, so that HP higher management realizes this issue...

http://www.hp.com/hpinfo/execteam/email/hurd/

I got a response that it was "forwarded to the appropriate people within Hewlett-Packard for review and action, as needed."

If we mail like this en masse, hopefully we will get a suitable announcement that includes our models too..

 

Also go through this thread on hp forums, where tons of hp customers are complaining about the faulty nVidia GPUs

http://forums11.itrc.hp.com/service/forums/bizsupport/questionanswer.do?threadId=1274587

Post your concern too there and let hp know what mess they created by supplying us faulty GPUs for our hard earned dollars!

 

thx for the links.

 

Now I have my dv9500 back again (though the battery isn't charging... grrr) - and it looks like i have a Mobo with the new BIOS because the fan is going constantly, really annoying, especially as it's not even running hot - well, for this hunk anyway...

 

I give up. I am now facing the fact that when my two year warranty is up, my laptop will be thrown away sometime after that.
The motherboard fried just at 13 months, this was replaced, but not the nVidia card, so 75 days later, the motherboard is fried again. I'm still within my two year warranty.
I have taken good care of this laptop, I either blow out or vacuum the vents monthly, it'll always elevated, I am a normal user, not a gamer. I watch a movie or two weekly. I do run Seti, at 50% cpu.
They formatted my drive this time, and I refuse to do the bios update. I'm sick of the fan running all the time. Let the dang thing cook again.
Frankly, I'm hoping the motherboard fails every 2 months, maybe this will become a pain to THEM. I give up on HP, they should be replacing the faulty nVidia card too.

 

PROBLEM SOLVED

Got same problem all of a sudden.
After searching some forums i came across a solution that really worked.

There's some sort of a problem with this chip(dont ask me how and why)

So the solution:

1.Remove Heatsink(cpu-vga)
2.Remove nearby pcie wifi or/and bluetooth.
3.Get a hair drier(YES A HAIR DRIER)
4.aim the heat stream direct on the vga chip(aprox. 3cm away) for 5 mins
5.WORKING VGA CHIP AGAIN

Mine works now im actually posting this from my laptop

I'll get the link with from the original poster.
Although he hasnt given specific details on why this fixes the problem but as far as i get it, through time and heat levels some of the chip's pins when hot must not have contact(along with shocks)
Thank god i saved my laptop

 

Dude... i'm not sure that this really solved the problem. Its probably a temporary fix.

 

it has a point though...

Lead connections are so week i guess and with continuous heat and when they are hot if u shake the laptop(i dropped it several times) leads might get unstuck.
So a good heat directly onto the chip might warm them up and become active again.it worked for me im not kidding.
If this happens again it will be long time in the future cause 1st, i will have better ventilation cause i had it on my bed and 2nd i will use hair drier again(hot air).
if u wanna make ur laptop work just do it trust me.

 

prozak I've seen that solution before..for old apple ibooks...maybe it is the same kind problem...

 

Greetings,

I am having the same problem, but with one minor variation. My laptop works just fine as long as it's using the standard VGA drivers that auto-install if you uninstall the nVidia drivers that are actually used for the video card.

To be clear, I still get artifacts on occasion. I still can't load the real drivers or else I get a screen full of garbage every time I boot the system. I can't do anything with my laptop that requires video drivers (like play games that have 3d componants... even my solitaire program won't run properly)

I can still run many other programs and don't have to run my system in safe mode. With the VGA drives I am running my system at 1680 x 1050.

I really looks just fine and seems to run fine, but I can't do anything video intensive. I can't even plug in my second monitor through the HDMI port.

I thought I was just hosed on this deal and was going to have to buy a new laptop (which I might do anyway), but according to some information on the HP forums, I may actually get them to resolve my problem afterall.

To be clear, I LOVE my laptop. It ran fine for just under two years and ran things like fallout 3 and everquest 2 regularly. I didn't start having this problem until about a month ago, and I immediately took my laptop apart (per HP's pdf on the matter) and cleaned both heatsinks and the fan. Then I applied new thermal goo and put it back together. It ran like new for about 3 days and then crapped out on me again.

I am going to try to get HP to honor the offer that nVidia made and have them replace/repair my system. I don't want anything I didn't pay for, I just want my system back, functioning like it did when I got it. I understand a little wear and tear, but this is admittedly a known design/production flaw, and as such they should fix the problem.

There is one thing for certain. I will never use a laptop as a gaming system ever again. One laptop for business and one desktop for gaming. /nod

HP Pavilion dv9500t 17" - Intel T7500 2.20 GHz / 1x150GB Sata / 2x2GB DDR2 800 / Vista Home Premium SP1 / nVidia 8600M GS

 

Yeah I love my laptop too.
I'm sorry to say, but it will progressively get worse... soon your computer will lockup and you will get more and more artifacts on your screen. Just giving you a heads up so you can be more prepared.

 

GPU has gone again - so that's 3 in the space of 4 months

Add on top of that otehr background troubles i've had with incorrect battery detection causing it to randomly shut down and no on board sound and i'm despairing of ever having this machine properly working again - grr

 

are you serious? thats not good.... tell that to hp and hopefully they will give you a real replacement

 

You must be kidding - HP's only solution is to provide another mobo with the same faulty chipset - anything with an nVidia 8600GM in it is doomed and HP are refusing to deal with it (see hplies.com - a site devoted to this specific issue) - i'm now taking it to fair trading...

 

I have a dv9543 with video problems after 16 months, points, and blue stripes or red and only start to safe mode or without installing the video drivers. After looking for solutions in various forums try the hair dryer to Howrah and everything works fine. but not let the temperature of the gpu up a lot.

Other solutions reflow a more professional hair dryer.

hi guys i email mark hurd too
i urge everyone with this problem to email him too.
i think its the only way we can get a definite solution to this problem...

 

Everyone viewing this thread with the same problem please add your info to this list:

database.hplies.com

Explore the forums there to learn more. A lot of people are being hurt by this.

I had my dv2000t die on me from the nvidia card issue (geforce 7200 go). Hopefully with some better organization we can get HP to expand admission of this defect to include intel chipsets and extend our warranties too. There are some pending class action suits but i don't have the most up-to-date info on them...good luck and keep putting pressure on HP.

 

those were some interesting videos

 

I have HP DV9700 w/Nvidia 8600M GS. 2 months out of warranty. Same problem. Either the video will black out for a second with Error: Display driver nvlddmkm stopped responding and has successfully recovered or computer restarts with DUMP referencing nvlddmkm.sys. I restored the laptop to factory to ensure it was not a software conflict problem. Problem still occurs. HP says to update BIOS and Driver. That won't work since I did a factory restore and still have problem. Then they said reset the battery. Yea, right! Perhaps if enough of us complain we can get them to recall this series of laptop. Now I have to pay $398 + shipping to send to HP for new motherboard. HP has lost my trust. I will pay the $398 this time but next laptop will not be an HP.

 

HP has replaced two motherboards and the geforce 8600M GS in this dv9500t. The first time it failed, it was about 6 months out of warranty and I had to pay to get it replaced. Then it ran for two weeks and failed again, this time on the 90-day repair warranty. They replaced it again. After reading the posts here, I guess I better see if I can extend the repair warranty. I've had it back for about two weeks and I'm holding my breath. I'll join the chorus of complaints to HP ... they need a real fix for this.

 

Gee! Guys. You're making me nervous!!! I just got my first error with the nvlddmkm display driver. I'm selling out this creepy laptop before it gets worst. I think the reason I have almost two years without problems it's because I never play games on this laptop, just a few times when I first bought it.

Just because I want to know: Is it possible for me to get any kind of warranty purchased from hp? Or does it have to be done berfor the first year expires?

 

I dont even know, you should juist call hp and ask. But there were reports of people getting extended warranties and paying for it, but hp not registering it.

equals waste of money... be careful. The corporate world really does suck (not trying to sound like a hippie)

 

Are you guys still getting these kinds of problems? , it's almost 2 years now since HP gave me this laptop but I didn't have any one problem with it. And since my desktops currently out right now for some paint work, my DV9500t is 24/7 on.

ZERO problems whatsoever.

I've only sent it back twice on it's 1 year warranty, that's to fix the overheating - They replaced the heatsink. And the other one was about the dead pixels which is perfect now. I also asked them for a whole set of extra rubber paddings in case I lost the rubber paddings.

I feel sorry for you guys.

 

I recently posted this on a separate thread (DV9000), but wanted to add it here as well:

Hi all--

After doing a lot of searching online, I was able to come up with a reflow solution that works very well for my needs. I have had no issues with my video card for a month now, so if you are out of warranty and want a DIY, you might want to give this repair a shot. Many of you may be familiar with this and might be able to add some details. I also know there is a cool mod for the xps1330 on this site that bears looking for heat dissipation issues.

1. I recommend you watch the youtube video that shows how to reflow using a common heat gun....it's a good visual aide ( http://www.youtube.com/watch?v=CgTbkTK2iwk).

2. Next, review the following information to grasp the science behind the technique ( http://www.altera.com/literature/an/an081.pdf) and use the reflow profile given.

3. Grab the tools: I used an ordinary heat gun, a digital timer, and old-fashioned bulb oven thermometer.

4. Remove the motherboard and cover everything but the chip (heat sink and paste removed from the chip surface) you want to reflow in aluminum foil to deflect the heat from damaging any sensitive surface mounted parts.

5. Place a small coin (dime) on the chip surface to help the solder of the ball-grid array flow properly. Place the oven thermometer in close proximity to the chip (but not touching!). It is important that once the heating process begins that the GPU chip does not move to avoid shorting any circuitry on reflow.

6. Start the timer and heat the chip area using the Altera profile above, holding the gun about 6" from the chip surface. I used a slow, steady circular motion.

7. While cooling, be sure to avoid any contact with the board/chip. Let cool to ambient temperature.

8. Reassemble the chip's heat sink with appropriate thermal compound. Some people also add a 2 mm plate of copper between the chip and heat sink (sandwiched with thermal paste) for additional thermal dissipation.

Couple of comments to consider:

i) This is NOT a cure-all. Chances are the chip will fail again...although it's debatable how long this will take. I've seen success stories range from days to months online. Mine is still going after a month. This is merely to prevent you from having an expensive paperweight in your possession as well as buying an expensive GPU/mobo replacement for older laptop models out of warranty.

ii) Do not let anything bump the chip during heating as a precaution against shorting the ball-grid array below.

iii) I now monitor my GPU with a temperature program and make sure my fans are always running.

iv) The obvious caveats apply: try at own risk and realize any remaining warranty is void (but you knew that already!).

By the way, if there's a sticky for this mod elsewhere on this forum site, I apologize for duplicity....just wanted to help add a few more details for those considering this approach.

 

I have two 9700t's, the first one failed about a month ago (45 days out of warranty). I attempted the reflow to no avail. I ended up paying for the repair. Just last week, my second 9700t did the exact same thing. The reflow fix worked on this second notebook (so far...)

 

I hate warranties... the product always fail right after it ends. Even on my car, I had my cat fail like 2500 miles after the warranty expired. The dealership was nice enough to still cover it under warranty though.

 

I HAD a dv9700t with 8600M GS. I started getting problems booting after a couple of start-ups. The screen was all black but if you looked closely you could see the HP logo or the splash screen. I would play the battery pop-out/unplug game and that worked for awhile. When that failed to work any more, I had to resort to booting over and over again. That corrupted my Vista install and recovery partition. Everything would be OK for awhile and then it would repeat. I called HP support about this and said some other people had experienced this problem. They said they hadn't heard that and had me upgrade the BIOS which didn't work. Now at barely 15 months old, my $1700 laptop destroyed my hard drive tonight and won't boot-up at all. I would rather just put my money in another computer than spend $400+ to replace the mobo and repeat again. It was a great computer when it worked but it was a f**king POS in the end.

 

damn... sorry to hear about your really bad experience.

 

is it possible to order a mobo somewhere and put it in yourself? or is hp the only company that will offer a replacement?

 

have some great news, my notebook is up and running again.

called tech support whom were no help at all. said there was nothing they could do since it was out of warranty and not covered under the nvidia extended warranty.
emailed the ceo as suggested on an earlier page and was firm but very polite. this is really important. would you rather help out an asshat or a polite person who needs their computer fixed?
anyway, he forwarded the email and set me up with a case manager. the case manager checked my actual order number to see if my computer was covered and it ended up being so. he had a box shipped to me to send the computer to them to have it fixed, completely free.

shipping and everything was free. sent it out friday last week and it arrived today, 6 days later. they reloaded the bloated factory vista but a clean install is worth not having to spend the money.

IF YOU'RE ABLE TO DO THIS BE SURE TO BACKUP IMPORTANT DATA!!
its a good thing i backed up photos and documents and music because it has nothing on it now. completely factory, as if they sent me a new replacement computer alltogether.

there's no guarantee it won't go out again but i hope it at least lasts me a couple years.

my guess is the driver listed on hp's website was the main factor. i usually cool my computer but nothing happened until i updated to the latest video driver they offer. this was obviously a bad choice. don't remember where it is on the forum but there's a site that has custom drivers, including the one i used that kept my computer going a year and a half

good luck to anyone else working on this problem

 

Well my 2nd one crapped out finally, reflowing would only last a week at best. I ended up sending it in for repair. The POST/Splash screen and beyond was full of lines and colors and blocks of colors, nothing legible on the screen at all. After explaining to the rep on the phone about this, they asked if I wanted to pay ~$50 for troubleshooting over the phone. LOL, no thanks, just send me a box please.

 

This time it was covered under their warranty right?

 

2 different laptops same problem, one died a month before the other - so no. But there is a 90 day warranty on the repair (fwiw).

 

Shortly after I made this thread I contacted HP again. I wrote up a blurb and sent it to them via the CEO contact email that they list on their site and the regular support form. I didn't really expect anything from it, it was just one last shot into the dark. To my surprise I was contacted by a complaint manager. HP ended up repairing my laptop free of charge. No $400 fee. Kudos to them for that, but here I am nearly one year later, and about half an hour ago I bluescreened with a driver related error.

I get the feeling that something is slouching towards Bethlehem.



The blurb I sent:

 

wow, nice job!

 

Yep! Had my first errors this month and just 3 days ago the entire video chip failed. The screen lights up but no data, Vista booted just fine (I could hear the startup chime). Even hitting f10 got me into the BIOS (I couldn't see it, but I knew I was there since the HDD wasn't accessing to boot Vista).

I went through the loop with HP until I got Scott who offered me a discount on the repairs, from $400 to $300.

I suggest adding your complaint to this page:

http://h30434.www3.hp.com/psg/board...thread.id=4229&view=by_date_ascending&page=59

And linking to it in every one of your chats with HP tech support, and bringing it up in every conversation on the phone. GET A CASE MANAGER TO SEE IT!!! Enough complaints and they'll add 9500 to their list of Limited Warranty Extended Service qualified products. But HURRY, they'll only do it up until 24 months after the START of your initial warranty!!!

 

In case this hasn't been posted lately, go to hplies.com for the real scoop on this known Nvidia defect.

 

As much as I hate to necro this thread, I feel I should mention that my DV9500 failed an hour ago. Thanks for the link.

 

My dv9543cl failed 4 times in two years and HP finally decided to replace it with a dv7 a few days ago because I had the two year warranty from costco.

It took a lot of chatting to get them to replace it and over the summer I may have actually had my laptop for less time than HP did for repairs

 

Welp add me to the list. My DV9700 just died! I was playing a game last night and after an hour the laptop screen suddenly turned to pink static. I shut down the laptop and turned it on again it ran fine for about 5 mins then bam! Pink static. I then poped off all the back covers and blew out every nook and cranny with compressed air, blasted out the heat sink and same problem. Now the laptop doesn't even boot up. All I get it a black screen without even a beep.

I've used a cooling pad with the thing since the first week I purchased it. I've always kept it updated and now it's a paper weight...

 

If you don't have a warranty you can always go the ghetto route... Take the mobo out and put it in the oven. Seriously.

Remove any plastic from the board (including heatsink and fan, the ribbon cable connectors should be fine). Preheat oven at 200 degrees C, put mobo on four balls of aluminum foil, one under each corner, on the large tray of the oven. Put the tray back in the oven. Wait 6-8 minutes. Take tray out as carefully as you can, don't bump it into anything. Let the whole thing cool down for about 30 minutes. Put the laptop back together. It should work.

There's a 60+ page thread over at HardOCP about this, and a large number of GeForce 8 series cards (desktop ones) have been fixed by this method. I tried it on the board of a Nokia N73 that used to shut down randomly, it worked fine afterwards. If your warranty is expired and you have nothing to lose, it's worth a shot.

 

Look for your mobo hp part number - remove ac and battery, remove memory dimms; look for hp part number. Cut-n-paste mobo part number in ebay and see if someone is selling one. I've seen them run from $90 to $200, some with DOA and 30 or day warranty. I had my tx1220us tablet die 30 days out of warranty with same gpu issue. I going to give the reflow treatment a try and see what happens. You can also plug-in you mobo part number on HP's "parts surfer" website to what other 9xxxx series it is used in and look for that model on ebay. In any case - keep vents dust free - get some canned air and blow dust out. Keep vents open - don't lay laptop on pillow or blanket. BTW - if you don't want to take apart your laptop - I seen a reflow fix where you remove battery, plug in a, turn on the laptop, wrap well in a blanket, let run for several hours, unplug, wait an hour or so to cool, then pray it refowed by self-heating and is fixed.
