If your Dynabook Satellite Pro C40-H 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 14-inch laptop from 2020. 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 Dynabook Satellite Pro C40-H
Screen replacement
We replace the 14-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
SSD and storage upgrade
The Dynabook Satellite Pro C40-H takes an M.2 SSD. We clone the existing drive to a larger one so Windows, programs and files carry over unchanged.

Memory upgrade
Most configurations of the Dynabook Satellite Pro C40-H 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-H 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. On a 2020 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.

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-H, 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
- 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.
- An SSD and extra memory are simple upgrades on most models.
Data recovery from the Dynabook Satellite Pro C40-H
The SSD in the Dynabook Satellite Pro C40-H 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.

Where the Dynabook Satellite Pro C40-H sits in the range
Its nearest relatives in the Toshiba Satellite and Satellite Pro range are the older Toshiba Satellite Radius 14 (2015) and the newer Dynabook Satellite Pro C40-K (2022). Storage differs too: M.2 SSD, replaceable on the Dynabook Satellite Pro C40-H, 2.5-inch SATA drive on the Toshiba Satellite Radius 14.
Questions
Can the SSD or memory in the Dynabook Satellite Pro C40-H be upgraded?
The SSD can be replaced with a larger M.2 drive. Memory is in slots on most configurations and can be increased.
My Dynabook Satellite Pro C40-H 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 2020 Dynabook Satellite Pro C40-H 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 or number is on the label on the underside or back of the machine. For this model, look for C40-H.
