If your Dell Precision 5520 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. It is a 15.6-inch mobile workstation from 2017. 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 Precision 5520
Screen replacement
We replace the 15.6-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
Windows repair and reinstall
Windows 11 support depends on the processor: versions with an 8th-generation Intel Core or Ryzen 2000-series chip or newer qualify, and earlier ones do not. We check yours and advise.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.
Price confirmed before work starts
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.
Overheating and fan repair
A thermal service covers fresh compound on the processor and graphics chip, new thermal pads where needed and both fans cleaned. It is the usual cure for throttling and loud fans under load.
SSD and storage upgrade
Most configurations of the Dell Precision 5520 have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.
Price confirmed before work starts
Memory upgrade
Most configurations of the Dell Precision 5520 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
Graphics repair
The graphics chip is soldered to the board. Artefacts, crashes under load and a black screen with the fans running are diagnosed to the chip, its memory or its power stage, and repaired at board level where it is economical.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Dell Precision 5520, 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
- Graphics faults on these are board-level repairs: the professional graphics chip is soldered to the motherboard.
- Mobile workstations run hot for long periods, so dried thermal compound and dust-clogged fans are behind many of the shutdowns and slowdowns we see.
- Many configurations have two or more drives, sometimes in RAID. Tell us if yours does before any storage work, because it changes how data is recovered.
Data recovery from the Dell Precision 5520
The SSD in the Dell Precision 5520 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.

Questions
Can the SSD or memory in the Dell Precision 5520 be upgraded?
The SSD can be replaced, and most configurations have a second M.2 slot. Memory is in slots on most configurations and can be increased.
My Dell Precision 5520 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.
How much does a Dell Precision 5520 screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
Is a 2017 Dell Precision 5520 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.
