We repair the HP ProBook 640 G4 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 14-inch laptop from 2018. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

What we repair on the HP ProBook 640 G4
Screen replacement
Cracked, flickering or lined 14-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
Battery replacement
A new internal battery is fitted and tested through a full charge and discharge. On a 2018 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
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.
SSD and storage upgrade
The HP ProBook 640 G4 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 HP ProBook 640 G4 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 HP ProBook 640 G4 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.
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 HP ProBook 640 G4, 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
- A forgotten BIOS administrator password usually needs board-level work, with proof of ownership.
- ProBooks are straightforward to service, with replaceable batteries, SSDs and memory on most generations.
- Hinge and lid-mount wear shows up on older 450 and 470 models.
Data recovery from the HP ProBook 640 G4
The SSD in the HP ProBook 640 G4 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.
