    DV9000 ressurection

    Yeah... another one. Here's the deal. First, i have more DV9000 parts than i care to admit. And second, this one is as good as they got...

    Got it for free from a friend of mine, in exchange for me fixing one of his amplifiers. No case as he managed to sell that, and no HDD/RAM/CPU, but all the guts including LCD and battery. That was about 3 months ago. He told me the mainboard is likely beyond fixing. The thing is, this is an Intel board, and it has the G86-770-A2 on it, aka 8600M, with 256MB video memory. This was the most powerful GPU in the whole lineup, and only available on intel. Been looking for a board like this ever since mine (AMD, 8400M 256MB) first crapped out...

    Got some spare time today so i decided to see what it's about. First thing i noticed is that the GPU has been heatgunned to kingdom come. Dropped in a CPU and some RAM and attempted to power it up. A quick flash and dropped back dead. Measured GPU, shorted. Damn.

    Covered everything else in tinfoil, threw it on my homebrew BGA station (preheater + hot air station + BGA nozzle + arm to hold the hot air wand), and lifted the GPU. Came off clean, and the board does not seem to be as bad as it looked at first sight.

    Put the CPU and RAM back in and applied power. Lights on, fan spun... Card reader LED went out after a few seconds, which on these, indicates the board has completed POST. It's alive! All voltages good. Battery takes a charge too.

    The board still needs a good cleaning, but all the GPU pads seem to be intact. Looks salvageable to me. Now, there remains only one problem. A brand spanking new G86-771-A2, "fixed" revision, is around $40-$50. Which isn't exactly dirt cheap. I think i *can* source an used one for next to nothing to test, but i'm not sure whether this board could take two reballs.

    Post your opinions please.

    I would probably use a new GPU and hope for the best, but then again, $50 isn't much for me.
    I love putting bad caps and flat batteries in fire and watching them explode!!

      Re: DV9000 ressurection

      It isn't much for me either, but i'd just hate the look of soldering on a shiny new chip and having it do nothing.

      Hmm. Come to think of it, i've done enough of them that i feel confident i can safely lift the chip back off if this board proves to be toast, and then buy a sony vaio or something to use it in. I'll decide tomorrow.

        Re: DV9000 ressurection

        Looks like it's a tie between soldering a new chip straight away, or trying with an used one first. Well, i've got some news for you.

        I'll be buying a Packard Bell SB85 in about an hour, found it complete and untampered for a good price. It has the very same 8600M GS GPU, and of course, the same issue, no video. Of course, i'll be taking the chip off that and dropping it onto the DV9000 board to see if it works.

        Had a joblot of DV6000 boards i bought a while back, and this weekend i managed to resurrect another 4 of them. 1 had a power issue (shorted ceramic caps in the CPU VRM), and for the other 3 i swapped the GPUs from other boards that were damaged beyond repair. One of them also needed the NB reflowed.

        2 of those boards looked like they've been in an oven, yet they powered up just fine after soldering in good GPUs. So i'm confident this one will work as well.

          God those dv6000. I have managed to repair two with a broken diode in power supply and another one with reballing. Currently I am working on a dv6000 that turns off immediately after 0.3-0.8 seconds. Before that it would take 3-5 presses of power button in order to start it and complete boot normally but with some red lines! So I reballed GPU with a new one and still same symptoms and I am suspecting Northbridge. I will reflow it tomorrow and see how it will do. I checked for shorted caps but didn't find any. Maybe my approach is wronh cause I have never been able to identify a bad cap...

          Thanks for letting us know though!

              Yeah maybe you are right but I really want to fix what I get!

              Battery is charging but as soon as I press power button power led lights up for a split second only and everything shuts down...

                Re: DV9000 ressurection

                If you have no shorts on the power supplies the NB is dead and needs replacement. Measure across the ceramic caps on top of the NB. If any of them read shorted (under 3 ohms) then the chip is scrap.

                As for my DV9000... Well, i decided i just fix the Packard Bell, it's been working fine since then and i'm looking to sell that. Done a few more successful reballs and GPU replacements in the meantime, so i'm feeling confident that this one will work as well. A brand new GPU will be on order soon.

                  Re: DV9000 ressurection

                  On most caps on top of northbridge has either 0 Ohms one side and 25 Ohms on the other. Some have infinity and are fine. So a part of northbridge is shorted I think. That was what I suspected. Northbridge is probably toast and I am getting same symptoms on a Acer 5310 that one chip Northbridge/GPU, the Intel 943 and probably is also toast! Thank you very much for answering!

                  Love the feeling when you finish reattaching chip after reball and everything powers up!! Awesome! Did 2 Acers 5920G with MXMII cards and have a couple more waiting. Not easy but definitely worth it!

                    Re: DV9000 ressurection

                    Got some news. Guess what i picked up today? ANOTHER DV9000... This one looks pretty darn good, and it's got all the bells and whistles one could ask for. It's got the intel board, the 8600M GPU with 256MB, and also the blu-ray drive.

                    What it didn't have: No RAM, hard drives or HDD caddies and no power adapter. Displayed garbage when i put some RAM in. I turned it on and left it belly-up for a few hours, then turned it off and back on and guess what... It works just fine now.

                    And guess what i paid for it? $12.35. Now that's a catch.

                      Good luck. Where do you buy them from (Not that I'm interested myself, we have plenty of those models here for sale, just curious about Romania)?

                      If you ever need some Ultra Low ESR Tantalum or Aluminum Polymer SMT case-type caps, let me know. I've got more sitting here than I know what to do with.

                        Re: DV9000 ressurection

                        I just lucked out on this one. Some guy came into the shop today carrying this thing, he'd been carrying it around all day and nobody wanted to buy it. Especially since it was stripped of all parts with resale value; basically the only thing worth anything for other shops which don't do BGA rework is the screen, and there's very little market for 17" screens as those big laptops usually sit on a desk their whole life, so screens rarely break.

                        I have three 17" laptop screens, and i've had them for longer than i can remember. Nobody wants to buy them.

                        So anyway, since it was missing so many parts and also the motherboard was broken, it wasn't worth fixing for him, so he agreed to give it away for a little pocket money.

                            Wherever i can find them, locally. Last pair of 2GB DDR2 modules, currently in my Lenovo R61i, i put together from two laptops i bought for parts. They're usually in the range of $15-$20 per module (used, of course) for DDR2, and cheaper for DDR3, around $10 to $13 as the standard memory on laptops nowadays is 4GB DDR3.

                            Here's some pics. I knew i was going to need them so i bought two drive connectors for dv6000/dv9000 series last week. Now all it needs is a hard drive.

                                  That's also the typical price they go for around here "as-is", but with all the parts on them, maybe missing HDD at most. Well, the DV series typically a bit lower, as most people have already heard they're crap. 60-80$ for a complete broken one. But sometimes, being in the right place at the right time and saying the right words, will get you very very cheap stuff.

                                  Popcorning happens for 2 reasons:
                                  1) moisture trapped inside chip or board
                                  2) top heater too close to chip

                                  Try longer preheating times and more distance from your top heater to the chip.

                                  Damaged solder mask usually due to poor quality braid or not enough flux. Or your iron is not hot enough and you're scraping the board with the braid instead of gliding over it.

                                  Of course it's not permanent. In fact i expected it to crap out immediately after i shut it down, but i brought it home and it still works haha... This is a good indication that the chip is only beginning to get damaged, and some "special treatment" plus some cooling mods should keep it alive for another year or so... My "special treatment" for those chips is pulling them from the board, covering everything but the die in tinfoil, and heating up the die with my hot air station up to 260C. And no it won't die or popcorn or anything if you left only the die exposed. Then reball and fit it back to the board.

                                  If the chip is not badly damaged, this will get it running for a good while. If it's totally borked, it'll at least work long enough for you to confirm the fault.

                                    That's nice! Yes a proper reball will do the job even if I find these boards are easy to warp from preheater, you just have to properly seat and support them...
                                    Also I had my first mask accidental removal after 6 reballs and I think it was from not using enough flux! I bought mechanix pcb mask UV repair and did fantastic job! I thought it was toast but I manage to fix solder mask and do a perfect reball! 2 difficult repairs went perfect! I guess experience matters a lot on these things!

                                      Re: DV9000 ressurection

                                      Never had any trouble with DVxxxx boards warping, or pretty much any Quanta board for that matter. Compal boards (the blue ones) on the other hand... those are absolute rubbish. You have to be very careful with them.

                                      Just got done reballing the northbridge in a DV5 (AMD, dedicated graphics). It's the laptop i got as a gift when i turned 18, and my mom has been using it for the last few years. It died yesterday, less than a month short of being 5 years old. For a DV5, that's quite the achievement, given their poor cooling. It would power on for a few seconds then power off. Back up and running now.

                                      It's been anything but maintenance-free though, i had to replace the palmrest and screen frame a few years back because mom dropped it, and it's eaten 2 fans so far. After this intervention... I think it's time to sell it.

                                      I bought and fixed a Dell Vostro 1510 for my mom, but she didn't want it... until now that she had no choice, and guess what, now she actually likes the Dell better. Indeed, it is a much better laptop and would be less headache down the road, as it has an access panel on the back. The DV5... Well, every 6 months i have to take it all apart just to clean the fan and change the paste. I've gotten really tired of that.

We gave them technology, the latest, the kind even Vietnam didn't have. They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."
