ComputerCompatibility exists to answer two questions reliably: can I upgrade this, and which part will work? Here’s how we get to an answer we’re willing to publish. Content is produced with AI assistance and edited by the site’s editor; we do not physically test products.
1. We start from manufacturer specifications
Official spec sheets, service manuals, and maintenance guides come first. Retailer listings and marketplace titles are treated as leads to verify, not facts — they routinely list the wrong memory type or SSD interface.
2. We work from the standards that govern fit
Compatibility comes down to measurable things: memory type and speed (DDR4 / DDR5 / LPDDR5), maximum capacity and number of slots, whether memory is socketed (SO-DIMM) or soldered; SSD form factor (e.g. M.2 2280 / 2242), interface (NVMe PCIe vs SATA) and keying; charger wattage, voltage and connector. We work from those, not the marketing.
3. We’re honest about what can’t be upgraded
Many modern machines have soldered memory, non-replaceable storage, or locked platforms. We say so clearly. Telling you a machine can’t be upgraded is just as valuable as telling you it can — and it stops you wasting money.
4. We tell you to confirm by exact model
The same family can have very different internals across configurations and years. We point you to your exact model number and service tag/serial rather than implying “all versions are the same.”
5. We flag uncertainty instead of guessing
If we can’t confirm a detail against a reliable source, the guide says so plainly rather than presenting a guess as fact. Some manufacturers simply do not publish certain figures — ASUS rarely states M.2 form factors, and Dynabook’s regional sites contradict each other on port versions — and in those cases we tell you to check your own machine rather than pick a number.
6. We keep it current, and we correct what we get wrong
Models and firmware support change, and so does our understanding of them. Where a page has been reviewed against the manufacturer’s current documentation we date-stamp it; where it has not yet been re-checked it carries no stamp, so the absence of one tells you something.
In September 2026 we audited every model page on this site against manufacturer sources and found a significant number of errors — wrong charger wattages, memory described as upgradeable when it is soldered, and in some cases products that were never made. Those pages have been corrected and carry a visible correction note. We would rather show that history than quietly overwrite it.
7. Our recommendations and affiliate links
Some links on this site are affiliate links — if you buy through them we may earn a small commission, at no extra cost to you. As an Amazon Associate, we earn from qualifying purchases. It never changes which part we recommend. Picks are based on the manufacturer-published specification and fitness for the job; the reasoning is always shown and nothing is independently tested by us.
This page is for general information only. Specifications differ between configurations and revisions of the same model — always confirm against the manufacturer’s specification for your exact model and service tag before buying or installing a part. Found an error? Contact us.
