Wireless disabled in 10.04 after complete battery drain

[dagarshali]

The kernel version I have is 2.6.32-24-generic and the OS is 64 bit lucid lynx.
The hardware switch is set to on, but the the wireless is disabled. Found this after I accidentally drained my battery completely and it powered off. When I hooked up the power cable, wireless is grayed out
