Xtreme way of fixing laptop graphics card!

I guess I'll try this too on my display-dead Acer Aspire. The graphics chip is non removable. I wonder can I bake the whole mobo or should I take off some components first?

Or should I just get a hairdryer?

edit: and by the way, any idea on identifying which chip is the graphics chip?

Do you know what kind of graphics chipset you have? If it is nVidia or ATi, they'll be very clearly labeled.

You don't necessarily have to remove anything, but anything EASILY removed (especially plastic) is something you'll want to do.

A hair dryer probably won't get up to temps.

this is crazy!!!

I got now my copy of service manual. Seems that the chip is hidden from the eye until the whole mobo is removed.

What concerns me most is should I take off the processor or not or what components are may be damaged by the heat.

But thanks!

definitely take the CPU out, not completely necessary, but you have to "screw" the cpu in, you might melt the socket a little bit with the lateral torquing

Now this must be the weirdest thing I've ever done, but here I go, mobo in the oven :-)

During the dissasembly there was some tape covering part of the mobo. I tried removing it, but it tore some chip out of the mobo. I tried to reattach the tape and the chip, but since I've got no equipment for soldering such small parts I may have just screwed the mobo :-(

EDIT: Ok, motherboard baked and screwed now. The plastic tape I was first going to take off, but did not, got curled and detached several chips with it and somewhy the RJ-45 port (LAN) got loose (unrelated to the tape). Dammit. I guess the mobo just has to be disposed now.

EDIT2: Seems like the PCMCIA slot I was too lazy to remove got some damage because of it's plastic parts. But well, never used that anyway.

You definetly want strip it completly since you dont want anything else exept motherboard when you put something to oven, with hairdryer you want just to see the component you want to refresh the bga ball joints from.

Well, oven can remelt the broken joint in that chip.

Perfect example why you want completly strip off any exes plastic and metal parts but for the tape i think it allways need be removed but gently making shure you dont strip any needed parts off from pcb.

Well, it was an educating experience. Guess I put the laptop into closet until I find a cheap soldering iron and then try to fool with it again. Perhaps the story continues :-)

I see 10euros for cheap soldering iron in local store :)

And yeah, we all learn by doing these things, anyway this is Xtreme Systems and we do it that way :D

take a pic of the damage, i'd like to see which parts were moved. If you have them,all, it shouldn't be too big of a deal...

Diredesire, you can get the idea from this pic. I can get a sharper pic, if you think you can tell more from it.

Pic: Plastic tape curled in oven and detached some components

You can see on the left edge of the plastic one component clearly, then there are about 5 other smaller components.

I think we need sharper pic, i see only 2 components there that supposed to be in motherboard but i dont see any marks on motherboard side.
