My Acer Aspire 10 won’t power on, though I have an LED power light. I opened up the inside and reattached almost every cable, and it still won’t power on. I have went through almost every tutorial and still cant’t find an answer.

If you haven’t done anything before you notice the problem then it must be related to the ram, you need to remove it, blast air in the slot, clean the ram with paper and put it back.
