Repairs we carry out on the Dynabook Satellite Pro C40-G
Screen replacement
A broken 14-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
SSD and storage upgrade
The Dynabook Satellite Pro C40-G 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 Dynabook Satellite Pro C40-G 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-G 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. 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.
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-G, 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.
Data recovery from the Dynabook Satellite Pro C40-G
The SSD in the Dynabook Satellite Pro C40-G 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.
