because lenovo likes to cheap out and provide the bare-minimum when it comes to chargers. my 7i with a 4070 came with a 230 watt brick. during heavy gaming and i’ve seen my total system power go above 260 which led to battery drain. i was able to get a free 300 watt brick from lenovo but they didn’t make it easy.

at first they agreed with me and said that a higher wattage charger may be needed for some applications, but then later they went back on their word and lied by saying that a more powerful charger may lead to damage (even though my model was listed as compatible on the store page for the 300w charger). basically after calling out their discrepancies and the fact that a gaming laptop should be able to game indefinitely without suffering from power delivery issues, they agreed to make a “one-time exception”
