There may be a screw on the bottom labled KB...
remove that screw and gently prise the keyboard up. flip it towards the mousepad and disconnect the ribbon cable after loosing the small clips/stays either side.
other times you may have to remove the bezel first which means find and loosening all of the screws from the bottom and carefully unclipping the plastic surround. This would reveal screws on the top edge of the keyboard that can be removed to allow the keyboard to flip up.
watch some youtube videos of various laptop disassemblies and you should be good.
Much appreciated the videos were a great help, but I do need a reair manual as well any ideas where to get one???
