Dell OptiPlex 7440 All-in-One Repair
We repair and upgrade the Dell OptiPlex 7440 All-in-One at our workshop in Bermondsey, from power and start-up faults to storage upgrades and data recovery. It is a 23-inch all-in-one PC from 2015. Parts are matched to the exact chassis, so the model number matters when we quote.

Repairs we carry out on the Dell OptiPlex 7440 All-in-One
Screen replacement
The 23-inch panel is the front of the whole machine. We replace cracked, dark or lined panels and check the backlight circuit, because a black screen on an all-in-one is not always the panel.
Price confirmed before work starts
Windows repair and reinstall
This model does not meet Microsoft's Windows 11 requirements, and Windows 10 reached end of support in October 2025. We can advise on the realistic options, including a lightweight Linux or ChromeOS Flex installation.
SSD and storage upgrade
The Dell OptiPlex 7440 All-in-One has an M.2 slot and, on some configurations, a 2.5-inch bay. Machines that shipped with a hard drive are much faster once moved to an SSD.

Memory upgrade
Most configurations of the Dell OptiPlex 7440 All-in-One have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
We also carry out motherboard repair, overheating and fan repair, virus removal on the Dell OptiPlex 7440 All-in-One, along with stand repair, no-picture and no-boot diagnosis, port repair, Wi-Fi and Bluetooth card replacement and data transfer to a new PC.
Known issues with the OptiPlex and Inspiron All-in-One range
- All-in-one PCs use laptop-style parts behind the screen, so repairs involve removing the back cover or the display panel.
- A black screen with the PC still running is often a backlight or panel fault and not a failed computer.
Data recovery from the Dell OptiPlex 7440 All-in-One
The SSD in the Dell OptiPlex 7440 All-in-One can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.
