This system comes with a vista installed. Decided to convert it to ubuntu, so I pop in a live cd and install Ubuntu 9.10 formating the whole HDD. Currently the problem with the wireless is the external switch cannot be switch on or off. Below are the outputs for most of the commands.


lspci | grep 'Wireless'

Currently the problem with the wireless is the external switch cannot be switch on or off.Do you mean that the switch itself is defective or do you mean that the switch doesn't seem to change anything? Does it matter if you start the computer with it on? Or start it with it off and switch it on? Learn by trying both combinations and running:
rfkill listMay we see:
lsmodThanks.

The switch becomes defective. Turning the switch on or off does nothing. Went thru the shortcut keys and did not find anything keys that are of use too.

lsmod | grep 'iwl'I would like to see the entirety of lsmod. I am hoping I see some ami or acpi module we might manipulate.

This is a very difficult problem. It is the subject of an unsolved bug report on Lanchpad and a bit of Googling uncovers many people with Presarios with unresponsive wireless buttons in several versions of Linux and several versions of Windows.

Please try:
rfkill list
sudo su
echo 1 > /sys/class/rfkill/rfkill0/state
exit
rfkill listAny change?

Also, please do:
sudo tail -f /var/log/messagesNow manipulate the wireless button and see if the kernel is aware of any key presses. If so, jot down the code it records, perhaps something like 0xF4 or some such.

The first set of command did not change the rfkill list.
The Hard Blocked is still 'yes'.

And the log message still did not show any respond from manipulating the wireless button.

nvm.
As expected. Think it is time to get a Wifi USB adapter.
