Dell 27 All-in-One repairs and upgrades
Screen replacement
A cracked or dark 27-inch display is replaced with a matching panel. Where the picture is there but very dim, we test the backlight and its driver before condemning the panel.

SSD and storage upgrade
The Dell 27 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.
Price confirmed before work starts
Memory upgrade
Most configurations of the Dell 27 All-in-One 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 Dell 27 All-in-One shipped with Windows 11. We repair start-up faults, reinstall Windows cleanly with your files kept, and remove malware.
We also carry out motherboard repair, overheating and fan repair, virus removal on the Dell 27 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.
What we see on the bench
- A black screen with the PC still running is often a backlight or panel fault and not a failed computer.
- All-in-one PCs use laptop-style parts behind the screen, so repairs involve removing the back cover or the display panel.
Data recovery from the Dell 27 All-in-One
The SSD in the Dell 27 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. 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.

The M.2 SSD can be replaced, and some configurations also have a 2.5-inch bay. Memory is in slots on most configurations and can be increased.
