Hi,
I have exactly same issue as mentionned in this post : http://community.acer.com/t5/S-and-R-Series/Acer-Aspire-R7-571-Black-Screen-while-power-light-on-amp-Low/td-p/211431
But beside resetting 5 sec and 20 sec it does not help and laptop is not turning on. When I press the power button the blue light come for like 5 sec and i hear nothing and keybord or screen does not turn on and then light turn off. The blue light of charging is also hsowinign when i plug in to power source.
The laptop when i turned off yesterday was working perfectly fine, I just tryied to turn it on today and no response. What has just happend ? My wararnty expired 5 motnhs ago, this is not very good I paid 1200 dollars for this.
