I have a Toshiba Satellite a75 S209 that does not power on. When I plug in my power adapter all I get is the green led on the front of the laptop for power blinking non stop, no sequence just fast blips for ever. The led on power supply stays on solid. Every once in awhile if I unplug and replug back in, the power led and the orange battery led stay solid for about 3 seconds then it returns to infinite blinking on the power led and that's it. I have tried removing battery and holding down power button to no avail. When led on front for power blinks the fan on the bottom does a 1/4 turn every time it blinks. Any ideas would be very helpful. Thank you.
