Just send my g55vw to the service centre again. They also do t know what is the problem. And yeah I'm not sure it's 13th or not. But more then 10th times I go to the service centre.

your unit has made the trip for service too many times.
It's very clear that your unit was defective from the get go!![/QUOTE
