Hi, this problem is almost in the power IC, before i met the same, so i think it need replace the motherboars. Just i found the website is selling the sony laptop motherboards, maybe it can help you, good luck. http://nbhow.en.alibaba.com/
Try taking the battery out and just use AC adapter for power. Likely the unit is unable to charge battery due to bad connection inside the computer. I have the same problem and doing this allows me to use my system without the battery.
