Hi Gerald, I have seen my share of laptop repairs in the
past 4 previous years.

Indeed what you are saying is what I said before
and that is the fact that the bad Battery Pack most likely
was the only cause of the partly burned pcb mainboard and
probably not the charger circuit itself. And because the
Battery now is kept out of the equation (it wasn't working
anymore anyhow), and the Laptop functions like new again,
there is nothing left that can explode or burn anymore.
Because also the short circuit in the pcb mainboard is
completely removed. And you are of course in your right
to replace it by a new board because this old board would
fall out of any guarantee clause by definition.
But who says that your new board in time will not get short
circuited too? You see it could also be a construction
or development error in all those boards or that series of
components (that same charge). Or a bad charge of Battery
Packs in this peticular N71VG model? Anyhow this Asus laptop
is completely working again to fully satisfactory of the
owner. And the owner is warned about the Bad Battery Pack
and the previous burnt short circuited pcb and will not
use any battery in it anymore. Nor will she leave it on
unattended while not at home.
But as I said before this laptop was okay in earlier years
until it automatically broke down and this repair was the
only remedy. Buying a new board won't prevent this from
happening again.

Thank you Mr.Yogesh. Also because you were also the first
that didn't dislike my article.

Thank you Mr.Parasuraman. It is really not such a rarity at all because I've seen more of these burning pcb cases before! But it is the first time I wrote about it.

Albert - I'm sorry, but I can't agree that to repair a laptop in this way is safe. You don't really know what caused the short, or what other damage was done in the power layer. The burnt-out charging chip could be an effect, not the cause of the short. Laptop fires due to the failure of short-circuit protection systems are not uncommon - they are a last-resort safety device, not something to rely on as the only thing between you and disaster. To replace this laptop with a cost-effective 2U model from eBay is my safe answer. We must agree to differ I think.

Thanks Humberto. I appreciate your kind words. It was a very big
short circuit indeed! But it was also the only cause why the
laptop didn't work before. But in case a laptop doesn't work and
there is no short circuit problem, other reasons can be the cause.
For instance : 1. The Bios Flashable chip can be corrupt.
2. Or there is no 3.3V on the Bios chip so it will not work.
3. There is no active 3.3V Power Supply working on the Mainboard.
4. There is no active 5.0V Power Supply working on the Mainboard.
5. The Video chip is defect or doesn't get power.
The Power Supplies can be found on the mainboard were there are
always at least 2 big square Resistors mounted next to two or more
Mosfets. But concerning all dislikes I got, I think that someone is
deliberately messing up all articles on Jestine's repair Blog. And
without mentioning why he lost all arguments!
