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
