Hi Everyone;

          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.

I had similar problem with Lenovo T60 laptop. Random restarts, not being able to power it on sometimes etc. The problem was in some small connector on the motherboard. The only possible solution was to replace the motherboard.

I guess that the same solution goes for your friend too.

Yes looks like a bad connection on the motherboard.  

If your handy with a soldering iron you could fix this yourself, but taking the laptop apart and resoldering the port to the motherboard.  Its a bit tedious but it would work (if it is a bad connection) and it would save you a lot of money.

Hi Everyone;

         With a link illustrating the disassembly procedures provided by Gary Case of EE for this particular model of laptop, we will be taking it apart this weekend and look for any possible loose connection.  With the aid of several members of EE, I have reviewed several multimedia tutorials illustrating the proper stesp in soldering which should prove help if necessary.  Most likely though, the motherboard will need to be replaced.

          At any rate, thanks again everyone for the help.
