Task Manager shows it.

Yes, you can check without opening the case. Open Task Manager (Ctrl+Shift+Esc), go to the Performance tab, click Memory. Look at the bottom: it will show “Slots used” and “Form factor.” If it says SODIMM, it’s socketed. If it says “Soldered” or the form factor is listed as “Chip” or something generic, it’s soldered. On some laptops, it shows “0 of 2 slots used” if both are soldered onboard — that’s a dead giveaway.

If Task Manager isn’t clear, run CPU-Z and go to the SPD tab. It lists each slot and whether it’s populated. Empty slots will say “Empty” — that means you can upgrade. If it only shows one slot and that slot says “Bank 0” with no empties, it’s likely soldered.

Still not sure? Look up your exact laptop model + “RAM upgrade” on Google. Manufacturers often hide this info but someone on Reddit has already done the work for you.

If you see “0 slots” or “Form factor: Unknown,” assume it’s soldered and plan accordingly.
