We repair the Acer Predator 17 G9-791 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. It is a 17.3-inch gaming laptop 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 Acer Predator 17 G9-791
Screen replacement
The 17.3-inch panel is matched to the original by part number, including refresh rate and connector type, so games run as they did before.
Price confirmed before work starts
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. On a 2016 machine a worn battery is the likely cause of short runtime, and we measure its capacity before recommending anything else.
Price confirmed before work starts
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.
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
Most configurations of the Acer Predator 17 G9-791 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 Acer Predator 17 G9-791 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.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Acer Predator 17 G9-791, 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
- The graphics chip is soldered, so artefacts and crashes under load are board-level repairs.
- Predator laptops run hot and benefit from regular thermal servicing.
Data recovery from the Acer Predator 17 G9-791
The SSD in the Acer Predator 17 G9-791 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 Acer Predator 17 G9-791 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 Acer Predator 17 G9-791 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 Acer Predator 17 G9-791 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 Acer Predator 17 G9-791 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.
