Remove the battery and unplugged the power supply. I then held down the power button for 60 seconds. I then reinstalled the battery and the power supply and pushed the power button and voila !

You may need to repeat the process 2 or 3 times.

Good luck

i have an advent 6651 and that used to do something simmaler, when turned on the power lights etc would come on but no display, I had it repaired 3 times at great cost, repair men saying it was a loose graphics card etc, which was as I found out later was not the case at all, what I done is found ion the internet someone with the same problem and there solution (after the above had not worked) was to take the battery out, and the bios battery and then try and power up, it worked! all that money wasted getting so-called repairs, all to do now is replace the bios battery and battery and restart, and set the clock, hope this helps

works great thanks
