Review on Powerful 230W AC Charger for Lenovo Ideapad Legion Y920 Y910 Y900 Y740 Y730 Y7000 Y545 Y540 Y540-15 Y540-17 Y545-PG0 Y740-15 Y740-17 Y920-17 Y900-17 Y7000-2019 - High-Capacity Laptop Power Adapter Supply Cord by John Galbraith

Purchased to replace the factory 230W AC adapter that came with the Lenovo y545. The product was advertised as 230w, the specs says it's 230w, but the computer tells me the power isn't enough, and after some tweaking and experimentation I can confirm that it doesn't charge my computer. I may have a lemon, but I still recommend checking the Lenovo website to see if there are any sales before ordering. I ordered a fresh factory charger with 30% discount for about the same price.
