How to Check If Your Laptop’s RAM and SSD Can Be Upgraded

Find out whether your laptop has soldered RAM or free SO-DIMM and M.2 slots, whether it takes NVMe or SATA SSDs, and what to check about warranty before upgrading.

By Gadget Soch·16 Oct 2026·8 min read

Adding more RAM or a bigger SSD is often the cheapest way to get a few more good years out of a laptop. The catch is that many modern laptops, especially thin and light ones, have memory soldered directly to the motherboard, and some have only one storage slot that is already in use. Buying a module before checking is a common and avoidable mistake.

This guide explains how to check what your laptop supports, what SO-DIMM, M.2, NVMe and SATA mean, and what to consider about warranty before opening the case.

Quick answer

Open Task Manager, go to Performance and then Memory, and note “Slots used” and “Form factor”. A SODIMM laptop with a free slot is usually upgradeable.
Soldered memory (common with LPDDR4X and LPDDR5X) cannot be upgraded after purchase. Newer LPCAMM2 modules are an exception, but only a few laptops use them.
For storage, check whether the laptop has an M.2 slot, which length it accepts (2230, 2242 or 2280) and whether it supports NVMe, SATA or both.
Free scanners such as Crucial System Scanner, Kingston PC Scanner and CPU-Z help, but the manufacturer’s service manual is the final word.
Read your warranty terms before opening the laptop. Some brands treat RAM and SSD as customer-replaceable parts, others want an authorised technician to do it.
MacBooks with Apple silicon cannot have their memory upgraded, so choose the right configuration at purchase.

Step 1: Find your exact model number

Series names such as “IdeaPad Slim 5” or “Pavilion 15” cover several generations with different motherboards, so you need the precise model. Look for the full model or product number on the sticker under the laptop, on the original box or invoice, or in Windows under Settings > System > About. Brand utilities such as Lenovo Vantage, MyASUS, HP Support Assistant or Dell’s support app also show it.

Step 2: Check RAM in Windows Task Manager

Windows 10 and 11 show basic memory details without any extra software. Open Task Manager (Ctrl + Shift + Esc), click the Performance tab and select Memory. In the lower right you will see the speed, Slots used (for example “1 of 2”) and Form factor. On laptops a removable module is normally listed as SODIMM, while desktops use full-size DIMMs.

How to read it:

“1 of 2” with SODIMM: one slot is free, so you can usually add a second module.
“2 of 2” with SODIMM: both slots are filled, so an upgrade means replacing one or both modules with larger ones.
A form factor other than SODIMM, or a total that does not match a module size you would expect: the memory may be soldered. Confirm in the manual.
Some laptops use a mix: part of the memory is soldered and there is one SODIMM slot for expansion.

One caution: Task Manager and similar tools read slot information from the laptop’s firmware (the SMBIOS tables), so the count is only as accurate as the manufacturer made it. Treat it as a strong hint, not proof.

A quick PowerShell check

In PowerShell, Get-CimInstance Win32_PhysicalMemoryArray reports MemoryDevices (the number of slots) and MaxCapacityEx (maximum installable memory in kilobytes, 0 if unknown). These also come from the firmware, so use them as a cross-check.

Step 3: Use CPU-Z and memory scanners

CPU-Z is a free Windows utility from CPUID that reports memory type, size, timings and the module specifications stored on each stick (SPD). Its SPD tab has a slot selector: an installed module shows its manufacturer, part number and speed, while an empty slot shows nothing. Searching the part number tells you exactly what is fitted.

Crucial System Scanner and Kingston PC Scanner are free tools from memory makers that read your system details and suggest compatible memory and SSD upgrades. Kingston says its scanner reads system information from the BIOS and does not install software or access personal data. Both companies also let you search by laptop brand and model instead of running a scanner. They recommend their own products, so use them for compatibility information and compare before buying.

Step 4: Understand soldered RAM, SO-DIMM and LPCAMM2

SO-DIMM (small outline DIMM) is the traditional removable laptop memory stick, currently DDR4 or DDR5. If your laptop uses SO-DIMMs, upgrading is usually simple.

Soldered memory is attached directly to the motherboard. Thin laptops often use low-power LPDDR memory this way to save space and power. It cannot be upgraded later, which is why the RAM you choose at purchase matters so much. If you are still shopping, our laptop buying guide covers how much memory to buy up front.

LPCAMM2 is a newer option. It is based on the JEDEC CAMM2 standard and puts LPDDR memory on a compact module that is screwed down rather than soldered. Lenovo’s ThinkPad P1 Gen 7 was reported as the first laptop to use it, and Crucial now sells LPCAMM2 modules. Adoption is still limited, so do not assume a laptop has it unless the specification sheet says so.

Apple silicon MacBooks place unified memory inside the same package as the chip, so it cannot be added later. Choose the memory, and the storage, you need when you buy.

Step 5: Check the SSD slot, size and interface

M.2 sizes

Most laptops use M.2 SSDs. The four-digit size code gives width and length in millimetres: 2280 is 22 mm wide and 80 mm long, and 2230 and 2242 are shorter versions. A drive that is too long will not fit, and some laptops have a short slot that only accepts 2230 or 2242 drives.

NVMe vs SATA

M.2 is only the physical shape. The drive can talk to the laptop over the older SATA interface or over PCIe using the NVMe protocol. Kingston notes that SATA tops out at 6 Gbps, while NVMe drives are much faster. M.2 SATA drives usually have two notches (B+M key) and NVMe drives usually have one (M key). A slot built only for NVMe will not run a SATA M.2 drive, and older laptops may support only SATA, so check before buying.

To see what you have now, run Get-PhysicalDisk in PowerShell and look at the BusType column, which shows values such as NVMe or SATA. You can also search the current SSD’s model name (shown in Device Manager under Disk drives) to find its interface and size.

Is there a second slot?

Some larger and gaming laptops include a second M.2 slot or a 2.5-inch bay. Others have just one, so upgrading means replacing the drive and cloning your data or reinstalling Windows. Windows cannot see an empty slot, so rely on the manual or a scanner.

Step 6: Confirm with the manufacturer’s manual

The service manual for your exact model, usually on the brand’s support site, is the most reliable source. Look for memory type, speed, maximum capacity and slot count, plus supported M.2 sizes, NVMe or SATA support and any second bay.

Manuals also show how difficult the job is. Lenovo’s ThinkPad user guides, for instance, list parts as “self-service” or “optional-service” CRUs (customer replaceable units). On the ThinkPad P15v Gen 2 and T15p Gen 2, the memory module and M.2 SSD are listed as optional-service CRUs, while the built-in battery must be replaced by an authorised technician.

Warranty considerations in India

Warranty terms vary by brand and even by product line, so check yours before opening the case. Points worth confirming:

Whether RAM and SSD are listed as customer-replaceable on your model.
Whether there are warranty seals on the bottom panel, and what the terms say about them.
Whether damage caused while opening the laptop is excluded.
Whether an authorised service centre can do the upgrade for you.

If the terms are unclear, ask the brand’s support in writing before you start.

Upgrade checklist

Note the exact model number.
Check Task Manager for slots used and form factor.
Cross-check with CPU-Z or a memory scanner.
Read the service manual for maximum RAM, slot count, M.2 size and NVMe or SATA support.
Confirm warranty terms in writing if in doubt.
Back up your data before touching the SSD.
Follow the manual, including any step to disconnect the internal battery.
After the upgrade, confirm the new memory or drive is detected.

Frequently asked questions

Can I add a RAM stick of a different size or speed?

It often works, but mismatched modules may run at a lower common speed and may not get the full benefit of dual-channel mode. Matching the type, speed and size of the existing module is the safest choice. Your manual lists supported configurations.

Is the maximum RAM in the manual a hard limit?

It is the configuration the manufacturer has validated. Larger modules sometimes work, and some memory makers list higher figures, but results are not guaranteed. If you want a supported setup, stay within the manual’s figure.

Will an NVMe SSD work in any M.2 slot?

No. The slot must support PCIe/NVMe and the drive length must fit. Some older laptops have M.2 slots that only support SATA drives.
