Question about Computers & Internet

1 Answer

Ok. My Hp dv9000 had a bad nvidia chip. So I did a reflow with a pencil tortch. Then once I powered up it would take me into windows. After about 3 MIN it would shutdown still. So I figured it may still be a heat problem. I added a copper shim and silver compound. Then I added a 5 volt fan that I jacked to a usb port. When I powered up it was acting the same as it was before the reflow but with no loop. I figured I had a loose ribbon somewhere. So I took it apart again. Made sure I had all the right connections. Some ribbons were fragile from handling. I put it back together an now when I power up the only lights that come on are the power light and occasionally the huddle light. The screen flashes a quick white light and a click sounds 1 to two times before it fails to boot. All this happens within 5 seconds. Did I dig to deep? Are the ribbons my problem? I'm not sure. Im on my phone writing this. So needless to say I despratley need a solution. If anyone can help. Id be extremley greatfull. Thank you.

    Thank you for the tips. But its spotless. I've cleaned everything. Also its no longer a heat problem because it doesn't stay on for more than 5 seconds.

HP pavilion dv9000 display white and green vertical lines on startup previously I resolved by discharging the power but currently I does not work.


There's a problem with the graphics chip. If you own an xbox you probably have experience in reflowing BGA chips. If you're under warranty then send it back to HP.

There's tons of tutorials on youtube explaining how to reflow your graphics chip. If they tell you to use copper shims after reflow, do not do it; there is a high probability that you will crush the GPU die. There are many electronics shops that specialize in this type of repair, the cost is relatively cheap compared to the cost of equipment and effort. Here's a video of the procedure that most repair shops will use: http://www.youtube.com/watch?v=7f0OPnTMrDo

The screen on my HP dv9500 is black, computer starts up just fine, but makes all the right noises, everything lights up except the screen. It was fine last time I used it...


There are a number of possiblities here, the first being that the HP DV9000 series has a serious flaw, the Nvidia chip on the motherboard adjacent to the processor is a major culprit in the failure and brakdown of this model as well as the DV6000. What happens is the model overheats and "reflows" the solder on the Nvidia chip, which results in broken or "Cold" solder points on the chip. The chip is not the fault, it is in the process of making the board. The results of this problem manifest itself in a varienty of ways, such as no boot, no video, power cycling, etc. You can fix it two ways, take the board out and "reflow" the chip with a heat gun, or replace the motherboard all together, hopefully with one that has been "refurbished" to not have this problem. HP released new BIOS files to instruct the fans in these computers to run faster and longer, but you really should use a laptop cooler with these models, every little bit helps.

Now, having said all this, you may want to try rebooting the system and when it first starts to turn on, tap the F8 key and keep on tapping it until you see something come on the screen, if it will. If the multi option menu appears, then the problem may stem from a bad update, in this case, you could run "safe mode" and perfrom a system restore back a few days.

Get back to us and let us know what happens.

Acer aspire 7520g will not boot


Your reflowing of the mobo did the troubleshooting for you. Your mobo is bad and most likely needs to be professionally reflowed. The problem with the ACER in particular is not knowing exactly what chip is the bad one. I know for instance the chip on an HP board is usually the Nvidia chip which does many things for that system. The blanket trick works more as a diagnostic tool than actually fixing the board for good. You are probably in a position to either reflow your board or replace the thing. Good luck

Hi, our HP Pavilion dv9310ca went blank last night whilst we were browsing the web. The hard drive light doesn't seem to be doing anything. When the power is on the auto fan runs intermitently. Ever so...


Your DV9000 has experienced what we call the black screen of death for most DV series laptops that have not had their motherboards serviced since new. There is a chip on the motherboard made by Nvidia and it controls a great deal of what happens on the 9000. This laptop has had a design and workmanship flaw since leaving production. The solder points on the chip are the weak link, it's not Nvidia'a fault, I would say it is the fault of HP for not listening to its customers and not realizing that they have failed the public miserably. Your motherboard has to be "reflowed" or replaced. It is cheaper to try and reflow the board, which is reheating the motherboard to allow the solder to flow and reconnect to all the connections on the chip. This usually does the trick 90% of the time. For the other 10%, the board will need to be replaced.

Hp dv9000 the lights comes on but it will not boot up!! screen just stays black. makes a few clicking noises and then nothing. then turns itself off and on!


Faulty Nvidia Chip...
You need to First Check and see if your laptop is listed under the recall list.. Go Here To CHeck..
http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01087277&lc=en&cc=us

Match up your Model Number... Not the DV9000 number.. but your specific DV9000 version (ex: dv9123us) then see if your p/n is listed there... If it is, You will need to contact them either by online chat or by phone...
Explain what your laptops doing and that you found your laptop listed on the recall/extended service list...

If it's not listed...

You have 2 choices, 1 you need to Reflow the GPU/Graphics chip which involves reheating the Graphics chip to re-melt the Solder balls on the underside of the chip and reconnect to the board... THis is a process Done only by an experienced tech... the chip needs to be weighted, then heated to a certain temp, held, then cooled at a certain temp.... This will fix your issue...

Other Choice is to replace the motherboard..
You can email me for further info on Reflowing the graphics chip..

Your Graphics/GPU chip(s) Need to be Reflowed....
Due to Overheating Issues of the Dv9000, the Chips on the motherboard Fail, To Fix This Issue, the 2 chips will need to be "resoldered/reflowed" back to the Motherboard...You should first Check to see If your exact make/model is listed on the HP list of recalls for that dv9000 series... They will repair it at no cost to you as long as you aren't over a year out of your warranty

HP Pavillion dv9000 won't turn on.


Thermal Damage..

You first need to check the Fan and Heatsink Assembly.. Clean the heatsink Fins and Fanblades..

Then .. The Graphics Chip will need to be "ReFlowed".. Using Either Infrared or a Heat Gun...

Your Issue Is The Nvidia Chip... It Makes it's connection to the motherboard using solder balls on the underside of the chip...(it's located right next to the CPU).. Due to Thermal Breakdown - the Chip Can Lose Connection to Certain Areas of the ball grid array... Performing A Chip Reflow Heats the chip and reconnects the faulty areas.. Thus stopping the shutdown issues and fixing your video..

Hp pavillion dv9000 screen


You have an Intel-based laptop (sounds like it).

The failure is due to the vram on the mlb (systemboard). Good news is this is a common failure for the Intel's and is readily fixed, prob is the vram and nVidia chip need to be reflowed using a BGA machine (about the price of a Lexus).

Without a viable repair option, you'll need to replace the mlb. Part# located in the memory bay (middle cover underneath the laptop), and expect to pay upwards of $450 from HP for just the part. *** BEWARE getting this part from a 3rd-party vendor, as they may NOT have reflowed the chips and have the issue resolved
