New 170W Power AC Charger Replace for Len-OVO Thinkpad E440 E450 E555 P50 P51 P70 S431 T540p W540 W541 Yoga 15 36200321 45N0487 4X20E50574 ADL170NLC2A Laptop

Needed an extra to work from home thankfully it does work for my laptop

It works perfect for my needs. Great value for the money.

I just took it out of the box and hooked it up to my work laptop. I does nothing. A green light glows on the charger and nothing happens at the computer. Its a $20 brick.Update:Once I shut down the computer, the light on the back of the computer glowed orange and the charger began to charge the computer. When I powered it back on, the computer told me to plug in the AC adapter that came with the computer and the charge light went off.I can no longer say this does nothing, but it still doesn't work the way it should.Update Again: My job has assigned me a different computer, not newer, just smaller, a P51 from a P71. The charger is now working exactly as advertised and charges the computer whether it is on or not. I cannot give it 5 stars though, because the description say that it works for the P71 and it does not. You should be fine purchasing for the smaller models. 17inch owners should probably look at higher wattage power bricks.

Bought two of them for my and children's Lenovo laptops. Both worked for a short time and then just stopped charging altogether. The original chargers manufactured by Lenovo still work, but these don't. It's been less than six months.

Does not supply power. Do not buy.

Worked well and priced well
