Price confirmed before work starts
SSD and storage upgrade
The Dell Inspiron 15 3505 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.
Price confirmed before work starts
Memory upgrade
Most configurations of the Dell Inspiron 15 3505 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 3505 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.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. A battery of this age that swells should be replaced before it damages the trackpad or casing.

Charging port and power repair
Depending on the configuration this charges through a round socket, USB-C or both. We test the adapter, the port and the charging circuit to find which has failed.
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 3505, 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.
Notes from the workshop
- 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.
- 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.
Data recovery from the Dell Inspiron 15 3505
The SSD in the Dell Inspiron 15 3505 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start. Recent Windows machines often have device encryption or BitLocker switched on. If so we will need the recovery key, which is normally saved in your Microsoft account.
