Got my PB in Nov 18th.... I noticed the lines, they were not iritating me as umch when I first got it, but after a few weeks - my god they were a pain... Anyway I rang apple begining of the new year and described the problem, and they said I couldn't return the mac for a replacement because it was over 16 days, but I could get it repaired in an Apple Repair Center... I rang the repair center and they said they had not heard of the problem?? We are they mars? and could'nt guarantee a perfect screen... mmmmm So I told them I'll hold on for a while longer - till 10.4.4 comes out at least. Anyway in the mean time my Battery became problematic, one minute it would report full charged and hang at 99% - but reports on 87% of battery life left after 2 months??? The next it would shut down whilst on the battery without warning and when rebooted would report 47% original battery life... Irksome is not the word. So I rang apple aftercare support and reported that the battery was playing up and asked if they would replace the battery and collect the troublesome one... They put me through to Tech Support in India so I could get a case ID.. After 50 minutes of re-explaining the problem they gave me a case ID. Rang back aftercare support in Ireland, they now had the case ID and to my surprise they would just replace the entire powerbook rather than just the battery.... Why?? I don't know... Seems strange that the display which is a bigger problem is deemed to be repairable but a battery which is easily replaceble is deemed enough to warrant an entire replacement.. My PB is custom order too....?? What cost's more an entire machine or a new battery? Oh well, hopefully when it returns the new machine will have a perfect screen... But I wont hold my breath Has any of the new machines lately been screen perfect?
