I have an ASUS G73.
It falied to boot up after I shut it down in the middleof a Windows update [yeah I know I should have waited but I dont think the airline would have waited for me ;-I ].
Got to turn it on again and a few indicator lights came on but nothing else.
Inserted the backup disc I was instructed to make on purchase & nothing.
Found this site [Thank V.much to the original guy who started this idea] and found the string about switching it off, removing the battery and holding the power button down for at least 45 seconds.
Unfortunately that didnt work for me [might not have tried it enough times].
But out of the corner of my eye, I saw the bit about doing the former + resetting the bios [find the pinhole reset facility - mine is on the base - I managed to reset it with a pin].
Came up with the same Windows update screen, completed that and shut down again - Gulp! Will it now restart?
Thanks Chaps ;-I
Chuffed as nuts as we say ;-)
