    • Gently push down on the keyboard and slide it towards the screen. This will pop the bottom of the keyboard out of the casing.

    • The best place to push is on the frame of the keyboard by the power button.

    • Using the metal spudger, lift and slide out the keyboard.

    • When lifting the keyboard do not remove it completely because a cable will still be connected to the laptop.

Thanks for putting this together. I had what seemed to be a fault hardware wifi switch on my ThinkPad T420s. I used this guide to take apart the machine. I re-seated the connector next to the hardware wifi switch (and added a e-tape shim to force downward pressure on it when reassembled). After I made this makeshift mod, the wifi is working again.

Thanks

This is not the Lenovo Thinkpad T420. You can Tell by the RAM memory Slot Cover and the Position the RAM is put into its slot. the T420 RAM is Vertical Compared with being Horizontal in this Picture. that includes the cover also. Then the Battery Slot is a Dead Giveaway clue. The T420 Battery slot is in the middle. and this Picture has the battery slot to bthe left. Sorry Not Even Close. None of the screws he removes are on the T420. so this is Completely Useless. Thanks

You must not know how to read, or you are just stupid. It clearly says that the guide is for the T420s (the smaller model of the T420).

You must either not know how to read, or you are just stupid. The guide clearly says that it is for the T420s (the smaller model of the T420). Also, you should fix the numerous spelling and grammatical issues in your comment.

Keith Cloward: the title states that this is for a T420s, NOT a T420.
