Edit 2: the battery ended up failing out of nowhere, so I ordered what I thought was a compatible battery, but it was larger and a different voltage. However I plugged it in and it works fine. As it turns out, the smaller battery is meant for laptops that have a hard drive installed, not an SSD, so you can freely upgrade to the larger 60W battery vs the stock 42W for only 30 bucks! Just buy it and remove a couple screws on the bottom, swap the battery (keep your cable) and you're all set!!I won't rehash too much what other reviews cover. It works well for what I bought it for, (mostly schoolwork).Windows 11 installed okay, but to update the dell drivers you will need to go to the dell website and download the tool. Windows won't do any of this for you. The laptop is no longer supported for continued updates, but there are no driver issues with the latest windows updates. Even if you don't update the drivers, which I assume many people haven't bothered, you probably won't notice.As far as battery, with power saver feature on, I've eeked out 6 hours of life, medium low screen brightness, only using Opera browser and nothing in background. As it turns out, screen brightness is in fact not what kills the battery, it's the processor. If the fan has to turn on because of intensive tasks, you can watch the battery % drop before your eyes.I know most people don't get this laptop for games, but at best it's only capable of visual novels. Even 2D action games it struggles like it's the early 2000's playing browser games.For fun I booted up a 3D game, Neon White, at lowest settings. From a full charge, it lasted an impressive 15 minutes, with a totally unplayable frame rate.At any rate, works well for school work. The backlit keyboard is nice. It's lightweight and very quiet. Screen quality is clear. The physical laptop came flawless for "used", but it's cheaper plastic and scratches pretty easy. Not really a concern for a basic basic workhorse.Edit: I managed 8 hours of battery after removing all possible bloat ware and just using the internet browser. Pretty impressive.
