The is a really nice little laptop was lifecycled out before it had to many hours on it (my opinion). Upon arrival and setup in noticed issues with the touch pad causing the mouse to freeze when it was plugged into AC. I updated BOIS and drivers etc. Nothing would resolve this. I took a chance on a $19 replacement AC Adaptor I bought here on Amazon and that fixed it. All and all TC of $170 for this laptop is still an awesome price.The AC Adapter I bought is: IEFUU 65 Watt Dell Laptop Charger』Input: 100-240V, 50-60Hz~1.5A | Output: 19.5V-3.34A | Power: 65W | 𝐂𝐨𝐧𝐧𝐞𝐜𝐭𝐨𝐫 𝐒𝐢𝐳𝐞: Round Tip 𝟕.𝟒*𝟓.𝟎 𝐦𝐦 (Interior diameter: 5.0 mm - External diameter: 7.4mm).
