Acer travelmate 8571 schematic

[dj_ricoh]

Hello my friends.

Anyone got a diagram of this notebook?

Sometimes it powers up no display, sometimes with display.

Most of the time like 90% powers up for 5-10 sec the shuts down.

I found a lot of coils shorted to ground and I wanna trace them.

If you got it please share it.

Thanks

Vgfx_core shorted

Injected 2v 0.5amps, did not heat up.
BIOS had activity.

Cooked the board and now everything works. (Intel version)

LOL

One small victory for the oven again:-)

Re: Acer travelmate 8571

mate i don`t have a bga station and for some reason i will not buy one.

the place where i work now got high humidity .

i use extractor when i come but when i leave it comes back.
the basement its a scrap maker. if i leave a board here for 2 weeks it dies.

long story short i wont buy a bga to keep it home and this the only place i can keep my hobby alive.
and on top of that if i waste more then 2 hours on a notebook i smash to walls

now for instance i think the wall will see a dead sony vaio
