TOTALLY agree with the above ^^^^^
Also my Laptop repair company fixes ALL makes of laptops and I am not sure what you expect from being authorised lol....customers just want their lappies fixed.... nothing more....
All the best Brett
So far as I know, having a repair done at an authorized repair center won't void the warranty and may be covered under warranty.
With that said, I still wouldn't want the OP touching my 10 year old alarm clock as I'm rather fond of it
