My HP Laptop screen dead/blank after Update Flash failed

Default HP Laptop destroyed by an UPDATE.. help plz
I was just surfing around when HP update said an update will be installed in 5 min..so I just let it do its thing. After 5 min a message came saying computer will be flashed and keyboard and num pad won't work. Then a countdown started' which got stuck at 59sec. Laptop fan was spinning hot ,like as if I'm playing some high end game. Windows froze..everything hanged. This went on for half n hour. I couldn't switch it off as power key didn't work...so I removed the battery

Now laptop screen is blank. Laptop can be turned on but nothing shows ..screen is completely blank. DVD ROM spins. CPU runs and fans are spinning...but no HDD light indicator.

What da fuq just happened..Did HP deliberately screw up my already good condition laptop who gave them permission to flash my laptop'.If update requires a flash that could destroy a computer don't you think we shud be informed before hand.

None of the solutions given on the internet works. I did that method of holding power button for 60sec while unplugged and battery removed...didn't work. I don't have a cable to connect to an external monitor.
