Ok. so my Sony Vaio laptop 2006 model, it normally works even though we use a shorted battery of some sort. All of a sudden tho, it stopped booting all the way and randomly cuts off. Sometimes we had to hold the power cord in a certain way to get it to turn on, it would work fine once doing that. Now it won't go past the boot screen, like once you first turn it on, it gets froze at start screen. Then sometimes it makes it to the user menu screen and such...then turns off. Could someone help me, possibly explain what this means and tell me how to fix it, if possible. Thanks in advance.
