Repairs we carry out on the Dell Inspiron 15 3515
Screen replacement
A broken 15.6-inch screen is replaced with a panel of the same resolution and finish. We check the display cable while the lid is open.
Price confirmed before work starts
Battery replacement
A new internal battery is fitted and tested through a full charge and discharge. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.

Charging port and power repair
We replace worn charging sockets and repair USB-C ports and charging circuits at component level. The adapter is tested first, because it is the cheapest thing to be wrong.
SSD and storage upgrade
The Dell Inspiron 15 3515 has an M.2 slot and, on some configurations, a 2.5-inch bay. Machines that shipped with a hard drive are much faster once moved to an SSD.

Memory upgrade
Most configurations of the Dell Inspiron 15 3515 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Windows repair and reinstall
The Dell Inspiron 15 3515 meets Microsoft's Windows 11 requirements in most configurations. We upgrade from Windows 10, which reached end of support in October 2025, or reinstall Windows 11 cleanly with your files kept.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, overheating and fan repair, hinge and casing repair, virus removal on the Dell Inspiron 15 3515, along with USB, HDMI and audio port repair, Wi-Fi and Bluetooth card replacement, webcam and speaker faults, BIOS password removal with proof of ownership and data transfer to a new machine.
Known issues with the Inspiron 15 range
- Hinge mounts in the lid and base are a known weak point on Inspiron laptops. Caught early it is a hinge and bracket repair; left alone it can break the screen bezel and back cover.
- Many configurations shipped with a mechanical hard drive. Moving to an SSD is the most noticeable improvement for the money.
- The charging socket is a separate part on most models and can be replaced without touching the motherboard.
