I asked this question about diagnosing why the brightness control won't work. But now the laptop doesn't work any more (water ruined it), so is it possible to name it under someone who is interested in it or something?
Questions aren't transferable. As it's something that no longer affects you, and these things are quite make/model-specific I'm going to close it and refund the bounty.
If somebody else has this issue and wants to resurrect the topic, they can ask a similar question and if somebody pokes a moderator, we can merge in the current answers.
