Hero 2 problems

I plugged my hero 2 into my laptop which has Go Pro 2.0 Cineform. on it, and now it wont turn on.. Anyone had these issues?

I goggled the prob and a couple of fixes are out there but nothing permanent..

One is remove battery, sim card, plug into usb,, light on front flashes, insert battery, light should come on steady bright.. Leave hooked up till light goes out. could take up to a couple of hours..

Did it.... no good..

Second is remove battery and sim... hold shutter button in, insert battery, push on/off button.. should come up...

This works but soon as you turn it off it wont come back on..

Any help will be greatly appreciated..

Thanks
