my HP pavillion dv6000 is having a problem. at start-up the laptop beeps once long and two short ones. at the link 'http://ccm.net/contents/pc/bios.php3' it says it is a problem with the graphics card. the only problem for this is I do not know where the graphics card is located and how to fix this problem. if you have any possible solutions to this problem please post =)
In fact, in most of these cases, the problem is with the solder connection of the graphics card mounted on the motherboard. some people suggest to use a heat gun to heat the graphics card and reestablish soldering (quite unmanageable for me as I have no equipments)
Yesterday, my hp started working like a miracle. What I did was simply:
1) put the laptop on a bed or a similar surface to close the air openings below
2) wait some time (15-30 min or 1hour) and let it get warm enough
it worked for mine. hope it works for you too.. the laptop seems stable and does not give any more beeps (for now).. good luck !
This issue is most certainly caused by poor cooling design in the HP DV series notebooks.
The problem is caused by a few of things.
1. The Sticky thermal pad used to transfer heat from the Nvidia GPU to the heatsink which does not do its job
2. The fan speed and internal design do not allow enough hot air to be extracted from the casing.
3. The use of lead-free solder which is more brittle and easily cracks under high heat conditions.
There are a few ways to fix it.
The blanket method works because it overheats the GPU (and the whole board which is not really a good idea) and in turn re-balls the solder joints under the GPU this method is not recommended.
The heat gun method does the same thing but the main danger is overheating nearby components. Done correctly this works and has so far been effective as long as you insulate the heat using tin foil (aluminum foil)
The professional way to correct this problem is typically done by using hot air or infrared re-balling techniques where you remove the GPU, clean the old solder from it and re-ball the small GPU points and re-attach to the main board.
I would also advise replacing the gooey thermal pad stuck to the GPU with a 2mm thick Copper sheet cut to about 7mm by 8mm made from 2mm copper sheet.
Use arctic silver on the both GPU core and on the top of the copper heat sink.
This should keep the GPU about 10 degrees Celsius cooler compared to the stock HP DV2000.
If you use a notebook cooler pad with the notebook this should be enough to keep the machine working for awhile.
i was so worried because this problem......but this heating up the laptop worked like a miracle for me.
my laptop is working fine now. and I saved lot of money too.
i was sure from the beginning that this will work for me since my laptop was booting perfectly into windows-how do I know that without the display??
well folks the answer is- I switched on my laptop first I heard the 3beeps(1 long+2short), waited for some more time I heard the tune of windows startup+ once ur on desktop when u on/off WLAN u hear the sound. so I knew there's gotta be a loose connection which I read was the solder of GFX card.
so I did the procedure mentioned by mehmet24a and it worked for me :-)
many thanks buddy ur a genius.
Just an update, I took out the hard drive (very easy - just make sure battery is out first and notebook is unplugged). Then on bottom of laptop look for a number 1 stamped on the plastic. Loosen 2 screws, remove cover, then you'll see hard drive - take out 2 screws and pull up on plastic tab in the middle of where 2 screws were. Pull up and remove hard drive. Keep the screen open, then set the laptop on a blanket, towel, etc. to keep bottom all covered up. Plug in and turn on - after you hear the beeps it should just stay on until it overheats. Leave it there until it shuts off automatically. This will apparently re-solder the connection due to the extreme heat. Then leave it there covered an extra 20 minutes or so until it cools down. Then see if it works after putting back the hard drive and battery. This DID WORK for me and I was amazed. I want to thank all who contributed and to the original author of this because it saved over $400 for a new motherboard. It worked perfectly for me and boots every time, after that installed vista sp1 and sp2 and have restarted it at least 10 times so far and it is still booting every time. I hope it keeps working but it was definitely a good fix. I recommend downloading a program called SPEEDFAN which will monitor the temperature of your GPU - nvidia and after installing I put the shortcut in the startup so that it starts automatically each time and shows the temperature of the graphics chipset. I definitely recommend also blowing out all the vents with compressed air. Now my laptop idles around 52 degrees C to no more than 85 degrees under full load running 3d graphics. I think the trick now is to keep it from getting to a very high point such as over 100 C and melting the connection again. So keep the laptop OFF your lap and on a table and possibly get a notebook cooler that sits under the laptop for even better cooling. Keep an eye on your temps. Good luck!
Try the blanket trick..
It reallly took me about 1hr 45 min..
once u get the screen working reset it to factory setting using your recovery disc
then download the BIOS update and new graphics driver software.
I have nVIDIA chip.
Run th hp health ckeck and download the critical updates
Be catious while updating bios follow all instruction..
Try to avoiding it automatically going to sleepmode or hibernate.
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!
how are you there.
well I think the idea of Mr. mehmet24a is the the best one, because I sell a notebook hp dv6000 to some one, and he bring it to me after one day, to install a software for it , when I get it form it's bag I find the notebook still working in the bag ( in this case there,s no ventilation for ) and the temperature of laptop to become very high, after that, the notebook at start-up the laptop beeps once long and two short ones,
in this case I think it's need a heater to reconnect the socket, or reconnect the graphic with motherboard completely.
if you cannot disassemble your notebook, try with Mr. mehmet24a idea. may it's work probably.
F@#$ Me, that actually worked. mehmet24a, you are a god. I would have never thought that would work but it did and wow what a great fix. I just turned on the system, wraped it up in a blanket so it got nice and hot, left it for about 45 mins, turned it off, left it for a bit and turned it on and bang!, it worked. Thankyou, this forum has just saved me $275 for a new motherboard.
I have dv2815 and a dv2315. Bake the motherboard, not the whole laptop! (this means don't do the blanket trick!) Take your motherboard apart. The best guide I have seen is at this link 'http://forum.notebookreview.com/hp-compaq-voodoo-pc/228268-how-clean-heatsink-fan-assembly-dv2xxx.html'
Remove all the plastic tape/covers from the motherboard. Put screws or something in some holes on the motherboard to create legs for it to stand on. Set it level on a cookie sheet. Bake at 385 degrees for 8-9 minutes. This will reflow the gpu (video chip) back to the motherboard.
I plug the motherboard up to test (before completely reassembling the laptop). You can order copper shims and thermal grease to replace the thermal pad HP used, to prevent this from happening again, for like $5 on ebay or something.
Make sure you remove all lent/dust from the fan/heatsink, both of mine were plugged. Looked like removing lent from the screen of a clothes dryer. (the blanket trick will only add more!)
mainly the problem of your laptop is your vga card or mostly known gpu. it was a mistake of hp to use this such graphic cards coz its heating to much.this long beef is not a memory error is graphic card error. you may cool down the laptop and later on it will work but only temporary.a qualified tech. will help
I’ve already written how I repaired my laptop(dv 6735ee) 1st time by method given by mehmet. Well as it turns out it just a temporary solution. It did work but just for 4 days then again the same 3beeps. so this time I took it to HP customer care.
I told them that the problem is in the nvidia graphics chip so just change it. The reply I got was that they are not authorized to change a particular chip so they will probably have to change the whole motherboard. I submitted it anyway for getting a professional diagnosis. After 2 days I got a call by their engineer that my motherboard is damaged and the cost of repair was quoted to be Rs.21975($475), since my laptop was out of warranty. I was shocked, since in exactly the same price I’ll get a new/better/fast/advanced laptop.
So ASAP I called HP and asked them not to repair my laptop. I collected it from HP and took it to a local laptop repair shop in Nehru place (India). He changed the nvidia chip and the total cost repair was just Rs.3000 ($65).
It is running fine now, and I hope it will in future.
Good luck guys!!!!
Hi all, I tried to fix my HP dv2000 with VGA boot problem long ago by the way as the same [met...] said, but the time we are waiting for heating the GPU very long time. And now we can make the GPU heating faster by this way.
I open the bottom cover of the laptop (the RAM cover) and loosely a screw on the heatsink to open ... then wait about 5-10minute for heat the GPU and reboot. If it can boot then we close a screw immediately.
Wrapped the laptop in a piece of clothing, and put it in my bed, under the duvet.
It got very hot, and turned itself of. I pushed the power button, and.... NOTHING :(
I then read that you should loosen one of the screws from the cooler that is in the memory slot.
Loosened the screw, put the laptop under the duvet again, system shut down because of overheating.
Pulled the laptop away from the duvet, fastened the screw and KABOOM it is working =D
I don't think this is a long term solution, I think I need to improve the GPU cooling someway. Maybe replacing the cooling paste, or adding a piece of copper plating instead of the thermal pad (don't know if HP uses a thermal pad between the GPU and cooling, but saw that somewhere on the internet).
thanks mehmet its works like charm. I tryed to solve this problems in many ways: chaning memory, updating BIOS, but your method always works. I just covered the fan with paper and left it for 10-15 minutes. After that it started without noises. Thank you very much again!!!
... 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".
