it's scarry the first time, but it works fine....use a tiny wire like a 22 ga, cut a tiny bit from the insulation, 1/16th maybe, as soon as you heat the tip, it'll pull the insulation back anther 1/16th or so as you tin the wire, tin it to the insulation.... it should look almost like a pin when your done,then just cut it shorter, you only need a tiny tip.. if it winds up a blob you used too much...
then you line the pin tip up with the point of the switch.... it looks scary, but the heat will only pull the solder togeather..., that's why you only wanrt the iron tip on the wire pin end, so you can't heat anything else enough for it to stick to anything but the tiny solder point....... the molten solder on the wire tip will heat the solder point enough for them to flow togeather...if it doesn't work or pulls off easily, try again but just a bit longer... eventually you'll get it
this is why you don't want to use flux... flux will distribute the heat, & will increase the chance of flowing solder to the case of the switch
don't expect to be able to lift the laptop with this joint, but it should be solid enough that playing it back & forth slightly should't make it come off, it's then a good idea to secure them somehow.... some use hotglue, but I use tiny wires from the switch & route them tucked till I can find a place to strap them too, tiny wire tie, whatever..., you can then increase the wire size if you want, especially if it's a longer run....
when you touch your two wires togeather & the laptop starts, sit back & grin
