My laptop keeps turning off ever few seconds. I took it for examination but he couldnt know the reason. My battery stopped charging for a whole month and then started to charge. The fan barely cools but there is no sounds. When i unplug the wire it turns off dirrectly. And the battery never reaches 8% even if i charge it for a whole day. So most liky could the overheating be shuting it down or just the battery even when in conntact??
