I bought an Acer Aspire Switch 10 that is not powering up. When plugged in an orange light is on but when I press the power button nothin happens. I tried the hard reset power+volume buttons, power button for 30sec with and without battery, paperclip in pin hole for 4secs, reset the ribbon cables and still nothing. Is there any other solutions for this problem or is it safe to say the motherboard is dead?
