Remove these three screws (two black ones and one silver) Remove the WLAN card (or whatever you have there, that might hold down the mainboard) If you have a different model, you may have some other stuff here, so act accordingly. Remove the two black screws (the other is already removed in this image) holding down the WLAN card. This ribbon cable must be detached from the mainboardįlip open the connector and you can simply lift up the end of the ribbon cable Note that the screws down here are different, so sort the screws according to where you took them from so that you know where to put them back later. We need only to remove the ones that hold down the mainboard. Now let's start removing screws from the inside. With the keyboard and wrist rest away, this is how it looks in there (If not, you should have removed more screws!) Pull off their connectors. The wrist rest and keyboard should now come off nicely.

I tried turning on the computer like this, with all terminals disconnected, but the state of the switch was detected as OFF. (WARNING: Others have had problems with this step and suggest more gentle alternative approaches, see comments.) What worked for me: A firm grip with pliers, and a rolling motion towards the upper part of this image worked fine. In OFF position, the two rightmost (from this viewing angle) terminals were connected. In ON position, the outermost terminals were, or should have been, connected. A very good decision, one which I should've made much earlier! I endured the nasty Windows message boxes and WLAN dropouts for quite a long time, until I finally decided to get rid of the problem once and for all by electrically hard-wiring the switch to ON position. So it wasn't just me accidentally pushing the switch, although I admit doing that too. The glitches were still there, shutting down WLAN randomly and whenever I pressed my palm against the palm rest.
