I have also lost sound and Wifi on my P105. It happened after I tore down for overheating and put new thermal grease on all heat sinks. Device manager says everything is fine. I have no wifi light and diagnostic tells me wifi is not turned on. I am suspecting the multi-pin bus that connects sound/Wifi controller board to Mobo but am not sure how to test this theory. Is it possible to buy this ribbon/bus? Is it possible to buy a new sound controller board? Is it worth it. Also could not understand the soldering on the Tecra that Simon mentioned. Is the tecra different than a P105. Can someone explain more what/how to solder these connections?

I also have a toshiba 9100 with no sound or wifi, take a hammer to it and cut your losses.

Hello,
This is only site I found very useful information but this still could not help me. Here is the chronology of my problem…
Laptop – Toshiba Satellite Pro P100 (PSPAE)
1. Upgraded from vista business to windows 7
1.1 Everything was working fine(including wireless/sound
etc)
2. Had an urge to clean my laptops heatsink hence started
disassembling the laptop went ahead till I part opened
the back and almost unscrewed the screen and then
decided against it and put it back together exactly the
way it was.
3. Now after restarting…wireless and sound does not work.
4. My situation is bit different, as both (intel pro w
wirless and high definiton audio) show up in device
manager.
But my wireless switch does not work(orange led does not
come on) and system thinks sound is working but the
altec lansing speakers do not work….

5.Did I screw up anything hardware wise.

Please any help will be god-send, am open to repairing it myself if I have to.

Thanks simon trethewey. You saved my day.
I got exact same problem with an old Tecra 9100: no sound no wifi, and followed exactly what you did and solved the problem.
I appreciate your sharing on this blog.

I know this problem. I had a tecra 9k with no function of the audio pcb which included wifi sd card microphone or H/P(also the wifi led would not fucntion when the slide switch was operated,this provided a clue to the fault).The cause is dry joints on the interconnecting PCB multipin plug between the Sister PCB and mother PCB.To cure all ails, strip whole laptop down( manuals available on the net for free) and reflux the SMD connector pins on both PCBs and resolder. Job Done! ( this is not a software problem)

I know the likely cause of this problem.I had a tecra 9000 which lost all hardware audio/wifi/sd card reader/microphone operation.( note also the wifi LED does not operate with the slide switch which is a hardware on/off to the wireless lan card) this is the clue to the problem
The cause? it is the sister PCB SMD connector to the Mother PCB connector which has developed bad soldered joints due to thermal cycling of the Mother PCB wrt to the Sister PCB.
This connector is the long multi pin connector which connects these PCBs togther.
Cure is to reflux the surface mount connections of both PCBs relating to this connector and re solder.Nothing to do with software!!There are dissassembly manuals freely available on the internet. it is an easy job for the careful with a small soldereing iron and liquid flux.

I also have tecra 9100.And the sound,Wifi & SD card does not work.Tried various methods except replacing the I/O board coz I think it would be expensive.So my solution to all of you who own 9100 with problems with sound & wifi,to buy a usb sound device & wireless USB.Btw my usb also failed.So i bought a PCMCIA USB 4 port.I feel it is better buying external parts coz you can used it on other computers rather than invest in replacing costly internal parts of the laptop.
