Lenovo laptop ideapad 315IIL0581WE. You have visited to install Windows and upgrade memory.
You brought the memory by airlift yourself. When you bought a laptop, I think you bought it as an option.
It says 2018 so you might misunderstand that the model was produced in 2018. This is the memory manufactured in the 18th week of 2020.
I think it's a good time to misunderstand the computer parts that are marked as parking among the products produced in the early 20s.
Ex> If the cereal overflow is stamped like this, isn't it stocked in 2016 and 2017? It's something that might be misunderstood.
In some cases, I had to explain separately that the product was released in the 16th~17th week of 2020.
At first, I was confused, so I also asked the manufacturer about it.
There is a burden of opening a new laptop when upgrading memory.
Remove all the fixed screws and carefully open the lid.
The inside looks like below. I can see one expansion memory slot. The existing memory is soldered on the main board. The CPU is also attached to the main board, so it seems difficult to replace (upgrade) separately. Mainboard + CPU + RAM are all equipped with main components, so if the mainboard fails, it will cost a lot to replace it after the warranty period. (But most of the thin laptops that come out these days look like this.) AS centers often replace whole boards rather than repair them, so over the years, it's a better choice to buy new ones than to replace them. It's a waste of defective laptops, but I don't think it's a bad idea to buy a new warranty laptop with a little repair cost. If you've been using it without breaking down for about three years, it can be one way to dispose of it when it's working properly and transfer it to a new laptop.)
DDR4 8GB memory has been loaded into the memory slot.
It's time to wait for the screen to appear after reassembling. It's the most nervous moment. Sometimes it doesn't turn on even though it's not a big deal. No matter how carefully you work without the battery, if it doesn't turn on, it's roughly difficult.
The existing 4 gigabytes memory and the extended 8 gigabytes memory have been expanded to a total of 12 gigabytes of memory.
