What we repair on the Dell Pro Max 18 Plus
Screen replacement
Cracked, flickering or lined 18-inch screens are replaced with a matching panel. Where the picture comes and goes as the lid moves, we check the display cable and hinges first.
Price confirmed before work starts
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.
Overheating and fan repair
We strip the cooling system, clean the fans and heatsink fins and renew the thermal compound and pads. We check temperatures under load afterwards.
SSD and storage upgrade
The Dell Pro Max 18 Plus 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
Whether memory can be upgraded on the Dell Pro Max 18 Plus depends on the exact configuration. We check against the serial number before quoting.
Graphics repair
The graphics chip is soldered to the board. Artefacts, crashes under load and a black screen with the fans running are diagnosed to the chip, its memory or its power stage, and repaired at board level where it is economical.
Windows repair and reinstall
The Dell Pro Max 18 Plus 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.
Price confirmed before work starts
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Dell Pro Max 18 Plus, 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.
What we see on the bench
- These are recent machines, and many are still inside the manufacturer’s warranty. Check that first, as a warranty repair costs you nothing.
- In 2025 Dell replaced the Inspiron, Latitude and Precision names with Dell, Dell Pro and Dell Pro Max, and the XPS name returned in 2026. The model code on the base label, not the marketing name, is what we match parts to.
- Memory is soldered on the thinner models in this range and slotted on others, so we check the exact configuration before quoting an upgrade.
Data recovery from the Dell Pro Max 18 Plus
The SSD in the Dell Pro Max 18 Plus 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.

Questions
Can the SSD or memory in the Dell Pro Max 18 Plus be upgraded?
The SSD can be replaced with a larger M.2 drive. Memory depends on the configuration, which we check from the serial number.
My Dell Pro Max 18 Plus 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.
Why does my Dell Pro Max 18 Plus overheat or slow down in games?
Usually dust in the heatsinks and thermal compound that has dried out. A thermal service fixes it in most cases. If temperatures are normal and it still slows down, we test the graphics chip and power delivery.
How much does a Dell Pro Max 18 Plus screen replacement cost?
Price confirmed before work starts. The exact figure depends on the part your machine needs, and we confirm it before any work starts.
