My partner has had a Model P6645 for about a year now, the keyboard is pretty much illegible from use, which isn't great but maybe if someone can confirm if this is normal? She now stands a replacement external keyboard OVER the original one so it can be used. Not ideal. And then I would like to upgrade the memory, can this be done, what DIMMs (if those?) do I need to order and how do I open the laptop up, do I need any tools? Thanks! HP. Badly worn keys...
