I am helping a friend of mine with a problem with his laptop which is an Acer Aspire 3690 which does not power or start up. The problem starting with what appears to be a faulty connection between the recharger and the recharge port. Basically, the laptop would only power on if the chort was pulled up or wiggled. Now, the laptop does not power or start up at all. Upon visual inspection, I did notice the connection to be unstable or wiggly eventhough the soldered recharge port itself is securely atteached to the motherboard. Therefore, it appears the recharge port itself will need to be replaced. However, this port does not seem to be a replaceable part without replacing the entire motherboard. Speaking of which, could the motherboard itself be defective, thus, causing the laptop not to start up? I am not sure exactly what to look for to determine if the laptop motherboard is defective. I know from desktop pc motherboards, if the capacitors are slightly bowed at the tops, then, the motherboard is defective. With laptop motherboards, I am not sure though.
From a recently closed earlier post, I do have a referral for this problem. However, I am trying to learn as much about this laptop as possible just for future references.
Thanks in advance for any help given to this question.
