I`ve owned a Vaio VGN-NR110E for about a year and a half. It just recently started to power off at any given time and not power back on. Eventually after playing around with it, it will power on again. This has been happening more frequently as of late. Does anyone know if this is common in a Sony Laptop, knows what the problem is or can tell me what I can do to fix it Any help would be really appreciated.
