Re: VAIO laptop startup problem
I think I know what the problem is. This is ruling out that you have a virus and such. It's definitely a power issue and may not be related to your batter or power adapter. Those may be fine. I think there might be a bad or loose power connection from within the laptop on the motherboard, or bad power supply unit. If your laptop is still under warranty, have Sony fix it. Otherwise, you can weigh the option of the cost to get it repaired from the manufacturer and a new laptop.
