I have a lenovo G400.
The display goes off abruptly anytime and doesnt come back again.there is no keyboard response or sound after that.the fan is still on though.
I have no idea whats wrong.
Have you ever tried cleaning the ducts of fluff and dust?
@wee i have done general cleaning but not very detailed. Can that be the cause? Dust?
Does sound like overheat
you may need to open it up and check fan and cpu is clear of fluff and dust click here
@Fruit Bat, i will surely do that now!!
