We repair the Dynabook Satellite Pro C40-K at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 14-inch laptop from 2022. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Price confirmed before work starts
Memory upgrade
Most configurations of the Dynabook Satellite Pro C40-K 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 Dynabook Satellite Pro C40-K shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
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
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 Dynabook Satellite Pro C40-K uses a 2.5-inch SATA drive. Replacing a hard drive with an SSD is the biggest speed improvement available for a machine of this age.
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 Dynabook Satellite Pro C40-K, 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 Satellite and Satellite Pro range
- An SSD and extra memory are simple upgrades on most models.
- Toshiba’s laptop business became Dynabook; we cover both names.
- Satellite laptops are now old enough that failing hard drives and worn charging sockets are the usual faults.
