If your Lenovo Y50-70 has a broken screen, will not charge, runs hot or will not start, we can diagnose and repair it at our Bermondsey workshop. It is a 15.6-inch gaming laptop from 2015. Both the drive and, on most configurations, the memory can be upgraded, which makes it a good candidate for a refresh.

Lenovo Y50-70 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
Memory upgrade
Most configurations of the Lenovo Y50-70 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
The battery is internal and held by screws. We fit a new one, then calibrate and test it under load. On a 2015 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
The round charging socket wears and works loose. On most configurations it is a separate part on a short cable and is replaced without motherboard work.
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
The Lenovo Y50-70 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
We also carry out keyboard and trackpad repair, motherboard repair, liquid damage repair, hinge and casing repair, virus removal on the Lenovo Y50-70, 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.
Known issues with the Legion and LOQ range
- Hinge and lid problems were widely reported on 2020 and 2021 Legion 5 models.
- Legion machines respond well to a thermal service: fresh compound, new pads where needed, and clean fans.
- The graphics chip is soldered, so graphics faults are board-level repairs.
Data recovery from the Lenovo Y50-70
The SSD in the Lenovo Y50-70 can be removed and imaged on our own equipment, so files can usually be recovered even when the machine will not start.

Where the Lenovo Y50-70 sits in the range
Its nearest relatives in the Lenovo Legion and LOQ range are the older Lenovo Y510p (2013) and the newer Lenovo Legion Y520-15IKBN (2017). Storage differs too: M.2 SSD, plus a 2.5-inch bay on some configurations on the Lenovo Y50-70, 2.5-inch SATA drive on the Lenovo Y510p.
Questions
Can the SSD or memory in the Lenovo Y50-70 be upgraded?
The M.2 SSD can be replaced, and some configurations also have a 2.5-inch bay. Memory is in slots on most configurations and can be increased.
My Lenovo Y50-70 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 do I get my Lenovo Y50-70 to you?
Bring it to our workshop at Unit 1 The Willows, 80 Willow Walk, London SE1 5SY, or call 020 7237 6805 to ask about courier collection. We confirm the price before any work starts.
Why does my Lenovo Y50-70 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.
