Dell Inspiron 15 3511 Review
Dell Inspiron 15 3511 (regulatory model P112F) budget laptop with an 11th Gen Intel Core i3-1115G4, 8GB DDR4 on SO-DIMM, a 256GB NVMe SSD, a 15.6-inch FHD WVA non-touch display and a 41Wh 3-cell battery.
The Inspiron 15 3511 is Dell's 2021 entry-level 15.6-inch laptop, and one of the easier ones to repair: memory sits in two SO-DIMM slots, the SSD is a standard M.2 drive, and models with the 41Wh battery keep a 2.5-inch drive bay. Dell sold it with an HD TN screen, an FHD WVA non-touch screen and an FHD touch screen, so check which one you have before buying a replacement panel.

The FHD non-touch Inspiron 15 3511 uses 15.6-inch 1920x1080 IPS-type panels with a 30-pin eDP connector. Dell sourced them from several makers, including AUO B156HAN02.3 and B156HAN02.4, BOE NV156FHM-N3D and NV156FHM-N4Q, and LG LP156WFC-SPK1. Any of them fits as long as your original is the 30-pin non-touch type.

Dell lists two batteries for the 3511: a 3-cell 41Wh 11.25V pack (Dell G91J0) and a 4-cell 54Wh 15V pack. The 54Wh pack is longer and cannot be used when a 2.5-inch hard drive is installed.
Our verdict

Expert rating6.1 / 10
The Inspiron 15 3511 is a basic 15.6-inch laptop with a Core i3-1115G4, 8GB of DDR4 and a 256GB drive. The 1080p IPS panel, 1.73 kg weight and SO-DIMM memory slots suit home and school use for owners who like to upgrade RAM and storage later.
The screen is rated at 220 nits and the 41Wh battery is small. Graphics are integrated and the 60Hz panel is not bright or color accurate enough for creative work. Expect browsing, documents and video calls, not much more.
Best for
- Basic home and school use
- Owners who want upgradable RAM and storage
Not for
- Gaming
- Buyers wanting a bright, color-accurate screen
