Dell Inspiron 15 3520 Review
Dell Inspiron 15 3520 (regulatory model P112F) budget laptop with a 12th Gen Intel Core i5-1235U, 8GB DDR4, a 512GB NVMe SSD, a 15.6-inch FHD 120Hz IPS non-touch display and a 41Wh 3-cell battery.
The Inspiron 15 3520 is the 2022 refresh of the 3511 chassis with 12th Gen Intel chips and an optional 120Hz FHD panel. It keeps two SO-DIMM slots and one M.2 SSD slot. The 120Hz panel uses a 40-pin eDP cable, unlike the 30-pin 60Hz panels in the 3511, so a 3511 screen is not a drop-in replacement for a 120Hz 3520.
Inspiron 15 3520 screen replacement
Dell lists three panels for the 3520: HD TN 220 nits, FHD 120Hz IPS 250 nits non-touch, and FHD WVA touch. The 120Hz non-touch model uses a 40-pin eDP panel. Replacement listings name the BOE NV156FHM-N4U for the 3520, and Parts-People lists the AUO B156HAN13.1, BOE NE156FHM-NX2 and LG LP156WFJ-SPB3 as 40-pin 120Hz panels that also fit the Inspiron 15 3520.

Like the 3511, the 3520 takes either the 3-cell 41Wh Dell G91J0 or a 4-cell 54Wh pack (Dell V6W33). Check the label on the battery you are replacing.
Our verdict

Expert rating6.4 / 10
The Inspiron 15 3520 has a Core i5-1235U, 8GB of DDR4 in SO-DIMM slots and a 512GB drive. The 15.6-inch 1080p IPS panel runs at 120Hz, smoother than the 60Hz screens common in this class. At 1.66 kg, it suits students and home users who may upgrade RAM later.
The 41Wh battery is small and brightness is listed at 250 nits. Graphics are integrated, so skip it for gaming or color-critical work.
Best for
- Students and home users who want a smoother 120Hz screen
- Owners who want upgradable RAM
Not for
- Gaming
- Color-critical work
