HP ZBook 15 G3 repair in London: bring it to our workshop in Bermondsey or ask about courier collection, and we will confirm a price before any work starts. It is a 15.6-inch mobile workstation from 2016. 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 ZBook 15 G3
Screen replacement
We replace the 15.6-inch panel like-for-like, matching resolution and connector to the part number on the original.
Price confirmed before work starts
Overheating and fan repair
A thermal service covers fresh compound on the processor and graphics chip, new thermal pads where needed and both fans cleaned. It is the usual cure for throttling and loud fans under load.
SSD and storage upgrade
Most configurations of the HP ZBook 15 G3 have two M.2 slots, so a second SSD can be added, or the existing one cloned to a larger drive.
Price confirmed before work starts
Memory upgrade
Most configurations of the HP ZBook 15 G3 have SODIMM memory slots, so memory can be increased. We check what is fitted and the maximum the board supports.
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
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.
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. At this age, short runtime and sudden shutdowns usually point to a worn battery and not a board fault.

Charging port and power repair
A charger that only works at a certain angle means a worn charging socket. We replace it and test the charging circuit behind it.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the HP ZBook 15 G3, 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
- Many have multiple drives. Tell us if yours is set up as RAID before any storage work.
- The professional graphics chip is soldered, so display artefacts and crashes under load are board-level repairs.
- ZBook workstations sustain heavy loads, so thermal servicing matters more than on an office laptop.

The SSD in the HP ZBook 15 G3 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.

Questions
Can the SSD or memory in the HP ZBook 15 G3 be upgraded?
The SSD can be replaced, and most configurations have a second M.2 slot. Memory is in slots on most configurations and can be increased.
My HP ZBook 15 G3 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 HP ZBook 15 G3 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 HP ZBook 15 G3 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.
