Hi. Last night i was downloading and installing game and accidentaly unpluged power suply and my laptop turned off because of poor batery life. After i tried booting again it is showing me black screen (monitor is turned off) and I was unable to turn it on since. I removed battery and connected usb ports, unplugged hdd and ram, plugged it in again with no results. Also i tried removing power and holding power button for 1min but that didnt work either. When I turn it off by holding power button it turns off but immediatley after that turns on again on its own for couple of seconds and after turns off again.
