I experienced this problem last night, and seemed to have fixed it this morning.
SYMPTOMS: HP Pavilion dv9000, Win Vista x64 Ultimate. Running on battery, battery level became critical; windows went into 'Hibernate' mode. Upon plugging in to mains power, and resuming the Windows session, the Wireless is still disabled, no matter what position the switch is in.
POSSIBLE CAUSE: Critical battery switches off the wireless network card to preserve power. Motherboard seems to log this status but when re-connecting to mains power the card does not receive power again. Uninstalling the driver and getting Windows to re-install automatically upon re-boot does not work.
SOLUTION: Charge up the battery whilst the computer is running. You can charge it to a substantial level, say, above 25%. Disconnect mains power so that your laptop is running on battery only. Set your wireless switch to OFF (this is usually to the left position, away from the orange indicator). Now run your computer down to the critical battery level again (perhaps overnight). In the morning when you press the power button, the 'CHARGE' indicator (looks like a lightning bolt) on the front of the laptop should flash quickly, indicating that there is no charge in the battery. Remove the battery from the laptop's underside. Wait a couple of seconds, then press and hold the power button for 30 seconds. Keeping the battery off the laptop, reconnect mains power. Boot up your PC. When at the Windows desktop and all your startup programs have finished loading, switch your wireless on (to the right position). You should now have a blue light, and wireless should once again be working. You can now re-insert your battery. You might have to setup your wireless network connection again as mine seemed to be 'lost', but at least hopefully the main problem is now fixed.

Matt, i did what u said, and i'm happy because my wireless switch is WORKING! :) Hopefully it stays this way.
The flashing light on the front of your laptop is a low battery warning. There probably isn't enough power in the battery to turn on the laptop. You need to plug in the ac power adaptor and let the battery charge until the battery light turns from 'orange', to 'green'.
