So I have an Acer Aspire 5830TG-6659 that doesnt power up. When the AC adapter is plugged in, none of the lights are lit. Warranty expired so no returns. Yes the AC adapter works, tested with multimeter and with another laptop. I'm thinking either a faulty motherboard, loose connections, or a fried motherboard... I have opened it up and cleaned it and looked for any loose connections but nada.
