Repairs we carry out on the Dell Inspiron 17 3782
Screen replacement
A broken 17.3-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
Memory upgrade
Whether memory can be upgraded on the Dell Inspiron 17 3782 depends on the exact configuration. We check against the serial number before quoting.
Windows repair and reinstall
The Dell Inspiron 17 3782 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
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. On a 2019 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.

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 17 3782 takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.
Price confirmed before work starts
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 17 3782, 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
- 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.
Data recovery from the Dell Inspiron 17 3782
The SSD in the Dell Inspiron 17 3782 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.
