Help please. My Vaio laptop won't come on. On pressing the power button the 3 green lights next the button come on and stay on. The powerlight on front lip comes on and the orange battery light flashes twice every three seconds or so. Nothing else, no hard drive noise, screen dead. Just sits there and does nothing. Can turn it off again by holding down power button for 5 seconds or so. Have tried with and without battery installed, but no difference. Does this mean the battery has gone? It's probably about 8 years old now.
