ThinkPad RAM and SSD Upgrades: A Guide by Exact Model

A ThinkPad RAM or SSD upgrade should begin with the exact model and machine type. Closely related names can hide very different memory layouts, while an M.2 connector does not by itself establish drive size or interface compatibility. Before spending money in Kenya, identify what is installed, what the platform supports and whether upgrading is better value than choosing another laptop.

Catalogue and references checked: 20 October 2026. Prices below are Infinite Tech catalogue asking prices for the stated configuration. Confirm the actual unit, availability, accessories and written warranty before payment.

Lenovo ThinkPad T490s Core i7 8th Gen 16GB RAM 256GB SSD Non-Touch — catalogue model reference — Catalogue model illustration. Installed components and the condition of the unit offered must be confirmed on its product page.

The programming laptop guide helps determine whether memory or storage is the constraint. The T480, T480s and T490s comparison explains why similar names do not imply identical upgrade paths.

Use the ThinkPad buying guide when comparing an upgrade with a replacement laptop. The X280, X390 and X13 guide adds context for smaller models with generation-specific memory layouts.

ThinkPad RAM and SSD upgrades: verify the model

Choice	What to compare	Buying implication
T480	Socketed memory configurations in Lenovo documentation	Verify the occupied sockets and supported modules
T480s	Soldered memory plus one SO-DIMM socket	The soldered amount affects the final possible configuration
T490s / X13 Gen 1 Intel	Documented soldered memory designs	Choose enough RAM before buying; do not quote a socket upgrade

Identify the laptop before identifying the part

Find the full machine type and serial information on the device and in its firmware or system information. Use Lenovo’s platform reference and the matching maintenance manual for that model. A guide for a T490 is not automatically a guide for a T490s, and an X13 reference must match the generation and processor platform.

Write down installed RAM, installed drive model and available storage space. This separates a genuine capacity problem from a software issue or a nearly full disk. If the computer is mainly slow because of background programs, a storage purchase may not address the cause. Establish the problem and the required outcome before asking a technician for parts.

Read the memory layout, not a generic maximum claim

The T480s documentation describes soldered memory and a single SO-DIMM socket, while the T490s has no RAM upgrade slots. An advert claiming that every ThinkPad can take more RAM is therefore unreliable. Even where a socket exists, the installed configuration and Lenovo’s validated module options matter.

Ask the technician to identify the existing soldered capacity, removable modules and proposed final capacity in writing. Do not confuse a manufacturer’s validated configurations with a guarantee about every third-party module. If there is no supported RAM upgrade, consider keeping the current machine for lighter tasks or comparing a configuration with enough installed memory rather than paying for speculative work.

Check SSD interface, physical size and the data plan

An SSD purchase needs more than the word M.2. Confirm the drive’s supported interface, physical length, connector arrangement and any required bracket or thermal part for the exact machine. A spare slot intended for another function should not be treated as an approved storage socket without documentation.

Before replacement, make a separate backup and decide whether the new drive will be cloned or receive a clean installation. Keep account credentials, encryption recovery information and licensed software access available. Ask how the old drive will be returned or securely handled. The final check should include booting, expected capacity, storage health and your important applications, not just proof that a new drive fits.

Compare the full upgrade cost with a replacement configuration

Include the part, labour, data work and any new operating-system or software requirement. A useful RAM upgrade on an otherwise healthy laptop can extend its working life, but it will not change the CPU generation, screen quality or battery wear. Adding a larger SSD also does not create dedicated graphics or solve an application-compatibility problem.

Use the linked catalogue examples to compare the ready-to-use alternative. The T490s example already lists 16GB memory, while the T480s example should be examined for its exact expansion arrangement. Have a qualified technician follow Lenovo’s handling instructions, including battery isolation where specified. Finish by checking that the system recognises the intended parts and that ordinary sleep, charging and startup still work.

A practical buying decision

Upgrade when the documented design supports the required part and the complete cost makes sense. If memory is soldered and insufficient, choose another configuration. Keep the machine type, proposed part details and backup plan together before authorising the work.

Frequently asked questions

Can I upgrade RAM on a T490s?

Lenovo documents soldered RAM without memory slots. It is not a normal socketed RAM upgrade.

Does every M.2 SSD fit every ThinkPad?

No. Verify interface, length, supported socket and required mounting parts for the exact machine.

Will a larger SSD make the processor newer?

No. Storage capacity, processor capability and memory are separate characteristics.

Should I back up before an SSD replacement?

Yes. Keep a separate, verified copy of important data before any storage work begins.
