Satellite L505d Sound, Usb, Wifi, Card reader not working? Here's the Solution

So, I picked up a Toshiba Satellite L505d-LS5006 from a computer store clearance sale. Bought as a working, but requires fixing laptop. The sound, usb, media card reader and wifi would not work on this machine. I installed correct drivers, but these devices wouldnt even pickup in device manager. Same with Ubuntu, no response.

With a little bit of searching. Particularly here.

Found out out that there is a pair of capacitors, Numbered L4519 right underneath the mouse pad, that get either cracked or sheared off the motherboard because of the mouse buttons being pressed.

If you disassemble your machine with this problem, you will see that there is absolutely no space between the mouse pad circuit bottom and the motherboard. Hence, if you hold the laptop from a corner, and have a mouse button pressed, it's going to put quite alot of pressure on these capacitors. So much, that they get sheared off the board.

So, if you develop this problem. Open the laptop. Inspect the condition of the capacitors. They might be broken or gone completely. The advised and working solution is to reconnect the capacitors, which is highly unlikely, since they are a millimeter wide or so. Hence, Solder ball the connection. And it works.

I just got done solderballing mine. On start up the devices were recognized and the drivers installed. Please do make sure that the remanence of those capacitors are no where to be found on the motherboard or they will short something else.
