DV9000 ressurection

Re: DV9000 ressurection

just a quick question unique. when you cover board with tinfoil do you also cover the opposite part of the bga chip underneath? thanks man

Re: DV9000 ressurection

Of course not, otherwise how would the heat from underneath reach the BGA? I leave uncovered the board on the underside of the BGA and 1-2cm clearance around it.

Re: DV9000 ressurection

That's what I also knew. I was just confirming it because I saw a tech doing a reball with foil all over the board. He was doing a subcon job for a service center here in Phil and I was curious bout he's methods. I'm still gathering a lot of data coz I'll be doing my first reball this coming june

Re: DV9000 ressurection

Arm yourself with a lot of patience and never give up if you are going to deal with reballing!!

We'll be watching! Let us know how you go. I am also going to lash out and buy some reball stuff too, but not for a few months yet as I'm moving house.

Re: DV9000 ressurection

I've read some post of unique. And its quite informative, and he seems to do his stuff well. I already have a hotair station. Got reservations on 3 thermocoupler. Stencils are on its way. I'm saving some money for a good preheater. Flux is not a problem sponsered by dad I also bought 10 laptops which I think needs reballing most of them are HP's.

Re: DV9000 ressurection

Update. I had some time last night and installed Windows on the DV9000 i bought last week for $13. Guess what... the nvidia driver installed, got Aero, and it works in 3D too. Even overclocked.

I did have to fiddle with it for a few tries until it worked stable, but once it started up properly, it works great. And i didn't even have to take it apart so far. Battery's good too.

The temperatures otoh, are outrageous. Feel free to take a wild guess of minimum, maximum and average temperatures. In power saving mode and performance mode.

Re: DV9000 ressurection

After like half an year, i've finally decided. A brand spanking new 2010 d/c G86-771-A2 is heading towards me.

Re: DV9000 ressurection

Now that the new chip is on the way, i'm thinking about an addition to make this DV9000 better fit for my needs, and make it truly stand out from the rest. That would be replacing the glossy 1440x900 screen with a matte 1920x1200.

I've found some used screens described as working fine and no scratches, for as low as $60 shipped. What do you think?

going from glossy to matte its a UPGRADE
if it where up to me i`ll ban all the glassy screen for notebooks.
can`t see s%^t when its sunny outside

Re: DV9000 ressurection

I know. The Dell and the Lenovo have matte screens and it's a world of difference.

The screen on the DV9000 isn't excessively glossy though. But still, it's glossy enough to be a hindrance when lights are on in the room, or outdoors.

Re: DV9000 ressurection

I'm currently testing the DV9000 with a 1920x1200 screen from a Dell XPS M1730 and it works great. And i've found a screen priced so low it's a steal (on sale, 15% off)... Just to give you an idea, the price, including shipping from the US, is lower than what some regular 15.4" panels sell for around here!

I've asked the seller and he told me it has no scratches or bad pixels. He has very good feedback too.

Here are the datasheets for the two panels:
What's currently in my DV9000:

What i'm looking to buy:
http://www.panelook.com/LTN170WU-L02...view_8871.html

As you can see, a bit lower brightness (but it won't bother me), but also significantly better viewing angles, and it's NOT GLOSSY. Got the anti-scratch coating too.

Yes i was a bit stumped by the 17.0" vs 17.1" thing, but i've read the datasheets and under "Mechanical", all the dimensions (both exterior and active display area!) are exactly the same between the two panels, so i cannot figure out how LG called theirs 17.1"... Anyway, this is not important. What is important is that it will fit and it is supported by the mainboard. And the 8600M GS seems to be able to drive a 1920x1200 screen just fine. Tested Flash video in 1080p fullscreen and it plays fluidly.

Re: DV9000 ressurection

I tried this 'trick' recently with a 14" 1600x900 LED panel to replace a broken 14" 1366x768 panel. An expensive lesson was learned that 1600x900 LED panels need dual-DVI capable ports. Picture is present, but looks very very odd, as if everything is overlayed with scanlines, and it's very fuzzy. Oh well, maybe I'll sell this thing in the future and recoup the $70.

Re: DV9000 ressurection

Most 1366x768 laptops do not have dual-link LVDS cables... Sometimes, the problem can be solved by replacing the cable. Sometimes, the second link is missing from the motherboard so you're SOL. If you can get hold of a schematic, it will tell you.

1440x900 in the old DVI spec needed dual-link, and the schematic for the DV9000 says dual-link on the LCD connector, so i'm good to go.

Re: DV9000 ressurection

I've got a schematic. Good thing you reminded me, I've actually got to update my thread with the results. I think the limitation is on the motherboard in this case.

Re: DV9000 ressurection

I'm proud to announce i am now viewing Badcaps.net in 1920x1200. Yes, my screen is here.

The panel does have a few minor nasties. Two tiny scratches at the middle-top, one small pressure mark at the left-top, and a weird pattern of some light gray dirt on the right edge. The only one that's obvious is the one on the right, but given the amount of screen real estate that i have now, i don't think i'll be staring at the scrollbars all day.

Other than that, it's looking pretty good. The backlight is very bright and uniformity is good. It is an older model screen (2005) so it has a bit lower contrast and the backlight is stronger at the very bottom where the lamp is, but it's okay. I bought this screen for the number of pixels and the matte finish, and it does not disappoint here.

Considering what i paid for it, i couldn't expect perfection. I got the screen for $65 shipped, and postage alone cost $24. I'm happy with it.

Still waiting for the GPU to arrive, so i can make this a 100% reliable laptop. I've also got some more surprises.

Re: DV9000 ressurection

Great work. truly unique, lol

[Th3_uN1Qu3]

Re: DV9000 ressurection

New GPU arrived today.

I have a bunch of other laptops i need to fix till next week, so this one will have to wait a while, coz i'll need one whole day for all the replacements and mods i've planned. You'll see what it's all about real soon.

Re: DV9000 ressurection

Do you need to do a modification on the board to place G86-771-A2? Like strapy or other resistors.

[rookieme]

Re: DV9000 ressurection

no, it works like using G86-770-A2
