Dear all: My kid pushed laptop power supply cord into USB port and machine just went off.For few minutes it was not able to restart.Once charged fully,the power came up but screen was black like its off. Didn't hear any starting sound also.No sound of hard disk.From many days I was also getting Power surge on USB port.Some times I do hear fan running but any attempt to see any thing on screen just failed.Tried booting with bootable disk also but invain.... Please help.. Thanks all for your time
