I have a Lenovo G550 Notebook given by an university to students.
The "M" key on keyboard flipped out due to poor build quality. Tried hard to replace it, bought new single key, however I've only failed because the keyboard electronics are also turned out to be damaged.
I have found a replacement keyboard from a local site, verified that it has the correct number and bought it. For the curious, it is around $50 here in Turkey.
I can't find a way to remove keyboard from Lenovo G550.
At first I thought it would be easy like ThinkPad's, but even with ALL the screws out (including the ones from CPU fan!) keyboard never ever moved a bit. I'm about to break much more keys while trying to move it. So I stopped.
Google searches only lead to ThinkPad models, (unscrew from RAM compartment, keyboard moves) but they DO NOT apply to this model.
I checked http://www.lenovoservicetraining.com/ion/ which doesn't have any information about G550.
I tried to remove Multimedia Panel (the plastic panel which has Power, Recovery, Mute, Volume Up/Down buttons) but the panel itself is incredibly tight and I'm afraid to break it.
How do we remove/replace keyboard on Lenovo G550?
I'm including some photos of the model with descriptions.
