forgot to mention
service provider is about 25min drive away from me.
usually take in for them to check then bring my laptop back with me
next week they called, bring it back to them in the morning they swap the part
late afternoon or evening go and collect it.
usually my notebook is still in a workable state so
I never leave it with the service provider.
I did it once, next day I found out my data was accessed.
file a complain to apple too.
