i have also tried reseating ram and cpu, pressing power button for 30s with no battery or charger plug-in, and clearing cmos battery.

Thank you for answering.

Remove power plug and battery,remove the ram for 5 minutes and replace. Insert paper clip into reset hole, then hold down the power button for one minute. Plug in the ac adpater and press power button see if anything changes.
