Acer Predator Helios 300 PH315-51 Repair
We repair the Acer Predator Helios 300 PH315-51 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery.

Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Acer Predator Helios 300 PH315-51 repairs and upgrades
Screen replacement
The 15.6-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
SSD and storage upgrade
Most configurations of the Acer Predator Helios 300 PH315-51 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 Helios 300 PH315-51 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
The Acer Predator Helios 300 PH315-51 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.
Battery replacement
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. 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.
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.
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Acer Predator Helios 300 PH315-51, 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.

Questions
Can the SSD or memory in the Acer Predator Helios 300 PH315-51 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 Helios 300 PH315-51 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.
Is a 2018 Acer Predator Helios 300 PH315-51 still worth repairing?
It depends on the fault. A battery, SSD or charging socket is usually worth doing. A major board repair on an older machine may cost more than the machine is worth, and if that is the case we will say so.
Where do I find the model number on my gaming laptop?
The base label shows the model, for example A515-56, plus an SNID number. For this model, look for PH315-51.
