I have had this model of laptop for a couple of years now and one day it started randomly shutting off with a few jiggles of the power cord it turned on again. It started doing this more and more until finally it just wont turn on. Now when you plug it in the light on the power button comes on but no fans or any indication that is is on. After a few seconds the light blinks and then goes off do you have any ideas? Also the battery wont charge with the power cord and you can not turn it on without a power cord if you have any ideas on that it would be great.
