Hello everyone, if you have any idea where i should be looking for i am into it :) i have no keyboard backlight, i have the trackpad detected ( no fan spinning like crazy ) but no button click and no movement detection; sometimes the trackpad seems a bit crazy when i am typing an internet adress, it does not move but clicks behind where i am typing and stays in the top left corner. The webcam also does not work. Keyboard, bluetooth, wifi works fine, the computer does not run hot. The hardware components are fine, i changed the motherboard and the old one has no problem. The new motherboard i have had liquid spill and the “tech” guy tried to take off oxydation… with fuel. I soldered back some components, and i have the older motherboard to compare. That is why i am looking on the motherboard a missing or oxydated component: i was looking up the R5852, it seems missing on my new motherboard; weird thing, it is missing on my good one too. the good one does not start anymore because i killed it with a bad magsafe. Maybe i soldered back my R5142 bad also. If you could tell me what voltage i should look for and where, i would be eternally thankful. Thanks a lot :) here are some pics of what is missing!
yanndetrie this is only to answer your question about the component. R5852 is a “No Stuff” component. That means there isn’t one. It means that no components will be placed at that location on the board. To clarify in case this is unclear: There is no component that goes there.
