Inspiron 7400, upgrade of RAM
Good day,
I bought my Dell Inspiron 7400 a couple of years ago, and the warranty already expired. I have now installed Windows 11 on my laptop, and the 8G RAM is not sufficient anymore. My laptop is very slow now. I took it in to have my RAM upgraded to 16 GB. To my surprise, the technician told me that the RAM is built-in and they are unable to upgrade it.
My question is why Dell would design a laptop that you are unable to upgrade the RAM. This situation is forcing me to buy a new laptop, for which I don’t have the funds now. Attached are screenshots of my system information.
Please provide a solution for my situation.
Kind regards
Kenny Robertson

The two most common reasons are to keep the form factor thinner and the price lower. Soldered-on RAM has been standard on Mac notebooks for well over a decade now, and is common on 14" and smaller notebooks in the PC world and even on some gaming notebooks.
There are even business-class Latitude (and Thinkpad, etc.) systems that now have it.
I would not be surprised if most if not all notebook computers have soldered-on RAM within just a few years.
The only solution is an upgrade either to a newer system or to replace the system board with one having more RAM on it -- the second option probably makes no economic sense, since it will almost certainly cost more than the system is worth at this point.

@ejn63 Thank you for your response. Now that is very disappointing. I will try to replace the system board. Thank you.

Yes, manufactures often design with soldered RAM stating it's more efficient and allows for a thinner and lighter laptop, but in reality it feels like a convenient way for the manufactures to save on their manufacturing cost - less parts and easier assembly, charge a lot more for a higher memory option laptop build than a similar size aftermarket DIMM option would have been, if upgradeable (Apple was a great innovator on that, as ejn63 mentioned), and hasten planned obsolescence, like you are experiencing now.
Once thing to note is that while you may be able to find a (used) 16GB system board variant for your 7400 in aftermarket, it's not likely to be an economically viable option, considering the cost of the board and of the replacement - so make sure you price the whole end to end cost, and also what the options are if it doesn't work as expected after system board replacement, or just doesn't suit due to revision changes or what else, before deciding on something like that - it's not as simple with laptops as replacing a standard ATX board in a desktop would be....
