HP Laptop reball procedure with a twist

Meant re-flow, the intention was to simply illustrate another technique used not to convince anyone it is the most correct.

It's not a matter of being "most correct," simply a matter of whether it fixes it or not, i.e. "prevents the problem from re-occurring", which according to a trusted source, it doesn't.
 
Another problem for the HP DV series. Man, these things have some issues, especially with airflow.

Btw, if any of you end up with funky colored video after putting one of these back together, go back in and rock the display cable back/fro into it's socket.
 
I got this in the shop right now, but I dont think I have the equipment to reball this thing. Ive been reading and watching videos, but im still not sure.

I'm unable to watch youtube videos on this computer so I'm not sure which videos you guys are showing. (I'll have to wait until I get home to see)

I had one with the video problem. I saw one of the dv9000 videos on youtube and one on dv6000. What I ended up doing is taking the dv9000 apart. I used a heat gun to heat up the video card. Then I took out the heat sink cushion thing that was there. Never seen one like that so not sure how well it works for a heat sink. Anyways I replaced it with a Penny. I made sure that it was a bright shinny penny. I am now using this dv9000 as my laptop and haven't had anymore problems so far.

I'm kind of scared to write this because I'm worried that I may start having problems as soon as I get home.

Anyways for the quote above. It's not a hard process. The hardest part is disassembling the laptop. Man I miss the days that most people had desktops.:(

Me too, in regards to laptops being ubiquitous. I'm seeing more and more issues surrounding laptop motherboards and their need to be replaced, what a pain.
 
ok, couple questions.

Whats the best way to remove the chip from the board?

Then from what I can tell, I remove the solder from the chip, then replace it with lead solder, then do the same with the board side chip. Then reinstall?

Do I then Heat it back up to make sure there is contact?

Preheat the board, heat the chip until the solder is liquid and remove from the board. Clean and apply the new solder, heat it and let it set. Remove solder from board and clean (no need to apply solder to board). Align the chip and repeat the reheat/reflow steps. That's it in a nutshell.
 
preheat the board? is that the same way to heat the chip? I have tried searching, just not fully clear on this.

Thanks for your answer, gives me a little more confidence to do this!

Nope. Preheating the board involves (professionally) using an IR preheat station or (amateurishly) a griddle to heat up the entire board. Heating the chip requires a heat gun/hot air station and it focuses on the chip itself.

You can probably getaway with not using a preheat station if you're just practicing, as it's just used to help prevent potential issues, but It's good to do none-the-less.

On an off-note, it's funny how two people can have a civil conversation on one thread, and a somewhat heated debate on another. Praise the internet.

That laptop is going to last for about a week, tops...if it hasn't already died.
