My Acer Aspire 6530 powers on and then shuts itself off within seconds. I followed someone suggestion online and was able to get the laptop to run just with the power cord but it only worked for a few days.
The battery and power cord have been replaced in the past.
If this is the one where the lights flash and go off and then it does it over and over I have one also.
It has to be connected with the heat and the motherboard.
I changed memory and it worked for a sort time. If somebody ever finds the spot on the motherboard where there is a bad connection PLEASE PLEASE let us know. It is a good computer fully featured but it has a common problem
