Before buying a windows laptop how to know if the laptop RAM is upgradable or it might have soldered RAM?

To determine if a laptop's RAM is upgradable or soldered, you can follow these steps:

1. Check the Laptop Specifications: Visit the manufacturer's website and look up the specifications for your laptop model. This will often indicate whether the RAM is soldered or if there are upgradeable slots.
2. Use System Information Tools: Tools like CPU-Z or the built-in Task Manager can provide details about your current RAM configuration and the number of slots available. If there are empty slots, the RAM is likely upgradable.
3. Physical Inspection: If you're comfortable opening your laptop, you can check the RAM modules directly. Soldered RAM will be integrated into the motherboard, while upgradable RAM will be in slots that can be accessed and replaced.
4. Consult the User Manual: The user manual or service manual for your laptop may provide information on RAM upgradeability.
5. Contact Manufacturer Support: If you're still unsure, reaching out to the manufacturer's customer support can provide definitive answers.
