wifi network disabled

[LETHAL]

Hello everyone.

I have Dell Inspiron Mini 1018 netbook whith Kubuntu 11.10 (just installed), windows 7 and backtrack 5.
After installing Kubuntu i have disabled my wifi card from network-manager and now i can not enable it again.

network-manager 0.9.1.90-0ubuntu3

KDE version 4.0.1

After disabled network i tried to enable it again, but button "Enable wifi" is blocked.

sudo ifconfig wlan0 up
SIOCSIFFLAGS: Operation not possible due to RF-kill

sudo iwconfig
wlan0 IEEE 802.11bgn ESSID:off/any
          Mode:Managed Access Point: Not-Associated Tx-Power=off
          Retry long limit:7 RTS thr=2347 B Fragment thr:off
          Encryption key:off

i tried to make
sudo rfkill list
0: dell-wifi: Wireless LAN
        Soft blocked: yes
        Hard blocked: yes
1: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: yes

sudo rfkill unblock 1 (0, all, wifi)
sudo rfkill event

1318763709.202263: idx 1 type 1 op 2 soft 0 hard 1

After reboot nothing changed
Tried to rm rfkill and whith purge, autoremove, rm /dev/rfkill
reboot - nothing

I have booted in to windows 7 and there is the same situation (is adapter, no network)
I have booted in to backtrack 5 and there IS wifi network, adapter works greate.

I have no idea what to do.

any sugestions?

Thanks, LETHAL

set default bios configuration solved the problem.
Even if wifi adapter was enabled.
