So I had extensive liquid damage to my 2 month old macbook air that has to undergo tier 4 accidental damage. I forgot to ask them this, but if I pay this $800 charge to repair this, then will they still honor the warranty as before the damage?
They will not, to my knowledge. There will be a 90 warranty following the service, but I do not believe that they will honor the warranty following any significant damage, regardless of the repairs that you pay for.
