So much negativity here. If you want a high-end computer you have to pay for it. BTW, I paid $380 for mine and I am thrilled to death with it. I added 8 gigs of ram and it runs great. The only negative thing about it was the "S" mode. I ditched that with 3 clicks.

The starts at odd times, and overheating happens, and battery life is just 2hr and 40 minutes. That's too low. Like seriously they need to do something about battery. My system is brand new and I am concerned that I can use it for even a year without any issues.

If you want to have your battery last longer you need to go to settings, then power & Battery. From there you can adjust the power settings to suit your needs. I have mine set for best battery performance and I get over 6 hours of battery life. The screen is still bright and the computer performance is the same.

Was a bit sluggish with factory OS even after removing bloatware. During reimage with Win11 had to download intel disk driver on separate USB and install at the prompt to select disk before the system would detect HD. Also had to use a USB dongle for ethernet connectivity as it did not detect wifi during setup. After reimage and Dell drivers install system runs great.

Same problem with the i5,8 ram version. 2 hours of battery at best. In addition, the device gets hot as hell even while only browsing the net. Already waiting for a response from Dell support whether is it about a faulty device

GMane, Try uninstalling Dell Support Assist software. It causes crashes and overheating.

Can an ethernet card be installed in this model 15 3511 and use a docking station to connect through? I also have a Microsoft Surface 4 that I use a docking station to utilize the ethernet because it is much faster than using wifi.

are you serious ?, Lev-oh-no & Dell-boy machines exist. This is particularly flimsy though. Without the back cover on it almost goes floppy if held close to a corner ๐Ÿ˜ฌ๐Ÿ™ˆ But it does have 2 ram slots and a 2.5" expansion option though ๐Ÿ‘€ unlike a lot of others TBF.. Good job this was free salvage eitherway!
