a) Randy said that his "...HP 840 P elitebook won't open..." Nick answered with "You will need to get the laptop open to replace the hinges, unless they can be adjusted." One would have thought that Randy would have already been aware of the blatantly obvious, before encountering Nick. Accuse me of jumping to conclusions if you like but I think that the thrust of Randy's message was to ask how to get the lid open, before having to consider whether or not hinges needed to be replaced. b) Randy said "...I use it almost every day..." Nick answers with "It sounds like the hinges are stiff from how you described it." I would like to know how hinges be stiff as a result of very regular use. I'm not surprised that Randy didn't reply.
