I recently had a problem with my Bluetooth keyboard for my iMac. It simply would not switch on and type letters. I tried everything... changing batteries, new batteries, high performance batteries, checking and cleaning out any battery acid that had built up (plus a good deal of Google searches for similar problems!). But nothing worked.
I was on the verge of throwing in the towel and admitting defeat, but decided to pay the local Apple shop a visit to see if they could help. Put simply, they were fantastic. One of the 'Genius Bar' guys (the boffins in the store) identified the problem with a tiny misaligned disk on one of the battery connections and all was well again. He even threw in a new set of batteries. An all this was for no charge! I was very pleased.
This little story is a great little example of never being afraid to ask for help (even if you are an 'expert' if your field) as there may be someone else with that little nugget of knowledge you need to resolve your issue.
Apple are clearly leaders in the marketing of their products, but also in their customer service and support. There is a lot we can all learn from the way they operate, which the team at PC PAL and keen to emulate.
