The Dell Inspiron 17 3780 is a 2019 laptop with a 17.3-inch screen. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Repairs we carry out on the Dell Inspiron 17 3780
Screen replacement
We replace the 17.3-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. 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.
SSD and storage upgrade
The Dell Inspiron 17 3780 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
Memory upgrade
Whether memory can be upgraded on the Dell Inspiron 17 3780 depends on the exact configuration. We check against the serial number before quoting.
Windows repair and reinstall
The Dell Inspiron 17 3780 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 17 3780, 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.
What we see on the bench
- 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.
- Many configurations shipped with a mechanical hard drive. Moving to an SSD is the most noticeable improvement for the money.
Data recovery from the Dell Inspiron 17 3780
The SSD in the Dell Inspiron 17 3780 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.

Questions
Can the SSD or memory in the Dell Inspiron 17 3780 be upgraded?
The SSD can be replaced with a larger M.2 drive. Memory depends on the configuration, which we check from the serial number.
My Dell Inspiron 17 3780 will not turn on. Is my data lost?
Usually not. The drive is separate from the fault in most cases, and we can remove it and copy your files even if the machine itself is not worth repairing.
Is a 2019 Dell Inspiron 17 3780 still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
Where do I find the model number on my laptop?
The model name is on the base label or palm rest. The 7-character Service Tag on the base identifies the exact build. For this model, look for 3780.
