If your Fujitsu Celsius H780 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. The Fujitsu Celsius H780 is a 2018 mobile workstation with a 15.6-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 Fujitsu Celsius H780
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
Windows repair and reinstall
The Fujitsu Celsius H780 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.
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
The Fujitsu Celsius H780 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
Most configurations of the Fujitsu Celsius H780 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 Fujitsu Celsius H780, 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 Lifebook and Celsius range
- Lifebook business laptops are easy to service and common in corporate fleets.
- A BIOS password or a drive locked to the machine is common on ex-corporate units; we ask for proof of ownership.
