Laptop motherboard fixes with pressure

No, I'm not attacking the motherboard by carving off ICs or such.

I look at this way: it's like trying all the home remedies before submitting myself to surgery by a surgeon. Nothing to lose, right?

Might be helpful to poke around on the board with a sharper tool, like a philips screwdriver with electrical tape on the end to insulate it. Then you may be able to localize down to a more specific component.

Yeah, it would be helpful. But each troubleshooting attempt requires pressing on a specific spot (a particular IC, for example), then pressing the power button, and waiting... to see if the boot process succeeds. (The boot "gong" always works; the trick is to wait 10 seconds at least to see if the HD will start the loading of the OS.) Then powering off the board and starting again.

It takes a long time. Not like just blindly poking around until "Eureka!". (I wish!)

But they ususally do this before the plastic parts are attached.

Try it at home and you may find slag where you once had DIMM sockets.

Do you know this for a fact? The SODIMM sockets are surface-mount solder tabs just like all the other components. They look like they are soldered right along with all the other components...

Maybe. Maybe not. The board's toast, anyway. Nothing to lose.

tabs

YMMV, just be very careful not to go too high or too long with the temperature.

You'll have to be careful of the plastics. They will soften and may be ruined. The ones I've dealt with must have been added after soldering.

The localized pressure idea is a good one, but I'd stick with a totally nonconductive tool. There are many possibilities: popsicle stick, Bic pen turned around, plastic knitting needle, plastic tuner alignment tool, etc....
