Fantastic - it works !

Trying the blanket technique at the moment on my dv6353 but mines doesn't beep at all nor does the fan come on.
the board lights up but the screen is black and i hear no noise at all from the hard drive?

I tried the blanket trick and it worked for a short period of time then stopped. I am an Electronics Technician and I am able to reflow the solder on the part if I could get to the device. My question is how do I get to the portion of the motherboard with the nvidia device? Do I need to remove the entire chassis bottom? If I knew where on the motherboard the chip is located I could cut a access hole in the plastic chassis to make the repairs. Is the solder joint that is overheating on the bottom side of the motherboard?

I want to change nvidia chipset. it costs nearly 120$.
i'll buy it. but i don't know is this true solve.

maybe in next 3 mounts it'll repeat.

Thanks, but that's the problem - I want to try the method suggested by mehmet and JJ, but it won't turn on in the first place, and when it does, it freezes on the 'loading Windows' screen, so I was wondering if I should just leave it frozen to see if it heated up enough to try the suggestion. Thanks anyway.

I solved this problem. go to notebook service
100$ , nvidia chip reinstall. there was connection problem. it only worsk in hot.

now , it is working good.

i recommend notebook cooler.
i use REXPO , very silent. Tempature decrease 10C. it's fantastik and so cheap.

Well the blanket trick has appeared to work - it turns on now, yet my laptop still freezes every few seconds, which is irritating. But now at least I have most of my files on a USB so I have access to them at any time rather than having to buy a caddy. Thanks, Mehmet!

Mehmet you're a genius! worked for my pavillion dv6000 too!
Don't know for how long but at least I now have the opportunity to backup my files..
Thanks again!

Another happy success for the blank method.
I only hope it lasts....

... temporary fix at most. Even a reflow won't keep working if you're not solving the issue that causes this in the first place.

Disassemble the HP in question (field repair guides from HP are pretty easy to find on the net for most models), remove all tape/meltable shielding from the pcb (if you don't, tape will melt or curl up, actually REMOVING SMD components from the PCB as it curls up !), get some first grade flux, inject it under the nV core and try a "reflow with the paint-gun trick" if you don't have a real reflow station. If you do it correctly (guides can be found everywhere on the net, but none of them can be called "exact science" when you're doing this with home-garden-and-kitchen tools) AND make sure you tackle the really bad cooling problem of all DV2/3/6/9's by using a copper shim on the nV chip. This way, your machine can work for another year or two. Using a copper shim instead of the worthless "sticky tape" heat transfer which HP uses will drop the temperature on the nV core by 20°C Centigrade or better when done correctly. If you don't solve this, you're waisting your time as renewed failure will be a question of days or weeks at most.

Ultimately, the HP will fail completely there's -no- avoiding that, but I've done quite a lot of these kind of "quick fix repairs" and they work BETTER than what HP's service dares to present as "repair".

... and to illustratie my point : I'm typing this on a revived Compaq V3000 AMD machine (HP DV2000 lookalike) which had the same probleem (video dead). Before the reflow, the nV7300 went to 76°C IDLE (yikes) and fan at full. After reflow and copper shim repair, the V3000's nV7300 now runs at 54°C. The machine is much, much cooler and doesn't need any extra external coolpad or what else to reach this result.

Be advised though, even this is no permanent solution as only a real reballing instead of a reflow really takes care of the problem. Also note : upgrade your bios'es. HP (like many other brands) forces the system fan to run at higher speeds and more often to try and keep the machine cooler, and combined with the actions I discribed earlier, this does make your machine last a couple of years longer.

Holy crap! i tried the turning on my laptop covering the fan vents for about 45min, then restarting, and it freakin worked! hp help told me about 400 to send it in and fix the issue, i was ready to buy a new laptop and give up, but i figured i would give anything a try since either way it was over, but it worked! i just turned on my laptop, covered it w/ a blanket for about 30min, made sure it got good and hot, turned it off, and hit the power again when uncovered, and to my surprise, it popped on! my screen worked again. so far i've turned my laptop off and on agian 3 times today and it's worked every time. not sure if this will be a long term fix or what, but it's working now and i'm happy, heck i'm using it now to type! either way, it's worth a shot. seemingly it's worked for several other people, as well as myself, so what's to lose? that's what i figured, and i'm now a happy camper w/ a few extra bucks in my pocket save from not having to buy a new laptop! i can't thank whoever that is enough right now! same principle as taking your laptop apart and heating the video card, just a backwoods way that still works!

Guess what i found out on these websites.

the problem which we are facing is a scandal by HP and nvidia. join these forums. if lucky u can even get a free repair(which apple has given to its every costumer).

I just wanted to say, THANK you FOR THE REMEDY!!!!! i almost threw out my dv2000 out the window...or bought a new motherboard..its back to working order...for now.LOL
i tried the taking the HardDrive out, Turn on. then off. then put everything back together...BAM HP screen..
thanks again!!!!

wish us all luck now.LOL how long it will last...

I did the thing where you tape paper over all the vents, turn it on, cover it in a blanket, and let it sit. I let mine sit for a few hours (~3 hours) because it will automatically turn off once it gets too hot which in turn lets it cool down slowly. Afterward, I put in the hard drive that I removed earlier (because I didn't want it to possibly get damaged by the heat) turned it on and VOILA! IT WORKED!

THANKS!

A lot of people have mentioned the reflow method. Here are a couple of vids from youtube that may help.

I contacted HP Support but no help for me. I was told that my dv2000 model wasn't covered because it didn't have an AMD. The email is below. So, this not an nvidia / HP issue? It's because of an AMD incompatibility?

Your computer is not part of the Limited Warranty Service Enhancement, because we are just having recall for the AMD based computers, Because its only AMD that is having compatibility issues with the motherboard that we had manufactured. Your computer has an Intel chipset which doesnt have any compatibility issues with our system..and the product number is not qualified too..if ever well be repairing your notebook, it will be for a fee.

Your HP Tech support,

Jeremy

I got the same problem with 2 DV9000's... :/

Wow that blanket thing is amazing!!!
