Acer Aspire 4810TZ Won't Boot

I have an Acer 4810TZ that is unable to boot. Basically what will happen is I will put in the battery and plug in the power adapter and immediately the white power LED (on the power button) will start blinking. Then if I press that power button, the fan starts running full speed, I hear the DVD drive and HD drive spin up a bit and then nothing happens. No Acer logo screen, no beeps, nothing shows up on screen, just the fan keeps running at full speed and the Power LED continues blinking. I can get the fan to stop running if I hold down the power button for a 3 seconds, but it continues to blink (white color).

The laptop was working as of yesterday, and now it just has a blinking power LED with no booting. I've tried powering on with the battery only, with the adapter only, and with both with no success. I've tried powering up with FN+Esc. I've tried holding the power button for 20 seconds without the battery or adapter. Nothing I've tried has fixed it so far.

My guess is that this is likely a dead motherboard and I should call Acer about it since the laptop is still in warranty. What else could I try to fix this?

 

call acer then ask them to replace the motherboard.....

 

in Warranty????....surprised ya even asked what to do...don't mess with it and send that sucker in to Acer.
