    Help….Saving my bacon(BUT). Broke wireless switch on someone else’s laptop.

    Morning everyone!

    Yesterday sure wasn't my day for working on computers, here's hoping for a better day today.

    In an attempt to make some extra cash cleaning the fans/heatsyncs on a Sony Vaio laptop I seemed to have broke the wireless switch, mounted on main board, during reassembly of customers laptop. First thought was to remove switch and bypass as I have done in the past. During removal of said broken switch I got in a hurry and managed to lift pad #2 along with the switch (Doh!....it was Friday evening and I got in a hurry).

    I have tried everything I can think of to get this wireless card to fire up but it's just not working. I'm far from being seasoned at reading schematics so I'm hoping that guy that's smarter than me (meaning most of you reading this) might be reading this post this morning and can offer advice of what should work for jumpering to get it fired up or other solutions? Also wondering if anyone knows where I can purchase these switches?

    Looking at the attached schematic, page 26, SW4 shows the broken switch. None of the capacitors are labeled on the board and I'm just not sure how to determine where the line goes to. I have jumpered from ground to pin 100 of U4A (Pg22) and that didn't seem to work. I have also jumpered Pin20 of CN12 (pg26) and still no dice. ANY thoughts or suggestions would be greatly appreciated! I can post pics of mainboard (my screw-up) if it helps any.

    PCG-3J1L
    Main Board: MBX-189

    (I have been replacing motherboard caps for the last 10 years so I do have a little experience in this area, just not the greatest with reading schematics)

    I got er fixed!

    Found enough of the trace from lifted pad to solder onto and everything's working. It's Saturday afternoon and time to enjoy a cold one.

                Micro Momentary Push Switch?
                by Natob82
                Great to be here! I'm a newbie here trying to find a "micro", momentary push switch to repair a Sony "clamshell" video walkman. This micro switch has long since discontinued by Sony, however I hope there are third-party switches of the same size and functionality that I might be able to source to play the same role. The purpose of this switch is to tell the video walkman that the user has activated the mechanical tape eject button, turning that physical action into an electronic signal that tells the tape transport mechanism to open so one can load or eject a video tape. I...

                NEC TurboExpress On/Off Power Switch Replacement Help
                by grimacelord
                Hello,

                I've been working on a NEC TurboExpress and I accidentally got the plastic inside the power ON/OFF switch too hot while doing other repairs and melted it. At first, it would still power on when sliding the switch, but you had to really press inward while sliding to get it to work.

                I removed the switch component and tried to gently melt the plastic back so it would work more reliably and all I managed to do was make it worse.

                I need to find a replacement On/OFF switch for this, but having some trouble figuring out which kind of switch I need....

                Help making a switch work the opposite way with a relay
                by SluggerB
                I have a very small float switch, I'm using in a very small tank. It only fits in one way. Link https://www.amazon.com/uxcell-Switch.../dp/B07DZ1J2GB

                I want the switch to be open when the water is high, and closed when the water is low. Unfortunately it works the opposite. And since this switch is designed to be underwater, it's all sealed up, there is no taking it apart or hacking it up.

                It will be driving a water pump, basic idea, when the water is low, switch closes, which turns on water pump, when enough water is in the tank, float switch floats,...
