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

it is not easy to replace a power jack for Lenovo ThinkPad T420S because it requires soldering job and people might burn the board while doing the job, you are replacing a power jack board, just disassemble and assemble the laptop, here is a seller for Lenovo ThinkPad T420S power jack board: http://www.dcincable.com/04w1699-04w3997...

Thanks for the writeup. How can I test if power is getting out of the actual jack and to the end of the powerjack module? Just wondering across what do I put the MMeter? Thanks. Matt

This guide is very well done. Thank you. Moving slowly and carefully, it took me almost two hours. So, I’d say the 30 minute time estimate is more for a seasoned laptop repair pro!
