Re: Toshiba satellite l505d

check KBC, and check +5v which goes to usb, and check sound chip voltage supplier, maybe both usb and sound chip gets +5v from same circuit. Anyway you need schematic. good luck.

Re: Toshiba satellite l505d

But first find coil L4519 and see that it is on the place and is soldered properly. If it is not check the schematic what SMD coil is it. You can shorted pads of L4519 to check it is working fine (this is filter that has no influence on laptop performance). If everything is ok with it and still no USB/sound reballing SB in needed to make it work (reflowing not always working in this case).
Good luck!
