We repair the PCSpecialist Cosmos 15 at our workshop in Bermondsey, from cracked screens and worn batteries to board faults and data recovery. The PCSpecialist Cosmos 15 is a 2021 laptop with a 15.6-inch screen. 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 PCSpecialist Cosmos 15
Screen replacement
A broken 15.6-inch screen is replaced with a panel of the same resolution and finish. We check the display cable while the lid is open.
Price confirmed before work starts
Battery replacement
We replace the internal battery and check the charging circuit and adapter at the same time. On a 2021 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
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
Most configurations of the PCSpecialist Cosmos 15 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 PCSpecialist Cosmos 15 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 PCSpecialist Cosmos 15 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 PCSpecialist Cosmos 15, 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
- Most have two memory slots and two M.2 slots.
- Thermal servicing is routine on the gaming models.
- PCSpecialist laptops are built on Clevo and Tongfang chassis. The chassis code on the base label is what we match parts to.
Data recovery from the PCSpecialist Cosmos 15
The SSD in the PCSpecialist Cosmos 15 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 PCSpecialist Cosmos 15 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 PCSpecialist Cosmos 15 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.
How much does a PCSpecialist Cosmos 15 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.
Where do I find the model number on my laptop?
The model name or number is on the label on the underside or back of the machine.
