After a furniture post, I have to follow up with one that isn't. This is about a Toshiba Satellite 1135-S155 notebook computer.

After picking up a Gigabyte Mini PCI GN-WI01GS (IIIB form factor) 802.11G wireless card, it worked great in my Sony PCG-SRX99, however the Toshiba I recently fell into didn't work. The physical switch is on, the adapter is recognized by windows, installed the Gigabyte driver and app, but it says the radio is off. Hmm... time to search the web.

Googling: toshiba wireless 1135-s155 802.11g

Returned this link on page #1: http://www.motherboardpoint.com/archive/f37-laptops.html

Which I've provided below. It worked! The chassis LED isn't lit for the card, but that's fine. I'm up and running. Who'd have thought covering pins 11 & 13 would fix it?

Just got mine to work based on suggestion passed on from "alkaprim"

I verified it using the electrical tape trick, but for more
reliability and elegance, I placed a "bubble" of clear nail polish
over the two conductors (one of my favorite tricks with nail
polish...). This bubble can later either be scraped off or removed
with nail polish remover as needed.

A more permanent solution would use a razor blade to slit the two very
thin traces that arise from these two pins.

The only question that remains for me is what is the real purpose of
pins 11 & 13 and what has Toshiba/Compal done differently with them
than other manufacturers?

Presumably these pins are used to turn on & off the radio which might
explain why neither the physical switch on the side of the laptop nor
the fn-f8 trick work to turn on-and-off the laptop.

If we knew what these pins did and how Toshiba uses them, we might be
able to recover this functionality with some creative jumpering rather
than just "covering over" pins 11 & 13.

Barring such a solution, what is the best way to turn on & off the
radio so as to reduce drain on the battery when wireless is not in
Possibilities include:
- Disabling the driver in the Device Manager
- Disabling the radio (and/or turning down the power) under the
advanced tab of the Linksys/Broadcom driver
- Removing the card [included for completeness ]

Any further insight or suggestions?
