Review on 🔌 Pwr 170W 135W Lenovo Charger for Legion & ThinkPad Gaming Laptops: UL Listed Power Adapter Compatible with Y700 Y7000 Y520 Y530 Y720 Y730 Y50 P50 P51 T440p T540p W540 W541 700 720 ADL135NDC3A by Tim Reimann

I bought this PWR brand to have an extra charger instead of the expensive Lenovo chargers for my P52. In fact I have four in all, the original, one of these and two other less expensive brands sold here at Revain. The reason I have so many is because I work in three different locations and also had to keep one in my travel bag. This one started working about two weeks ago and is only used about 8 hours a week when I'm at this location. First, the laptop switched to battery power. I was able to unplug it from the 120v outlet, wait about 2-3 minutes for the lights to go out, and plug it back in and it worked. Now the laptop doesn't recognize it at all when I plug it in and keeps running on battery power. Even after restarting it is the same. I can plug in any of my other three and they charge and work right away. Looks like something else to go for on ground fields as I'm buying a cheaper and more reliable option.
