我在笔记本电脑上启动了一个实时 Lubuntu usb，然后运行lshw下面的程序。（如果我忘记删除输出中的私人信息，请帮我删除。我只删除了序列号。还有其他我忘记删除的吗？）
它现在有 4GB RAM，对吗？
笔记本电脑最大可以支持多少 RAM？
笔记本电脑的型号是“C55Dt-A (PSCFWU)”吗？随后，我在 https://www.crucial.com/usa/en/compatible-upgrade-for/Toshiba/satellite-c55dt-a-(pscfwu-03p005)上面写着“最大内存：8GB”。
如果我搜索“C55Dt-A”，我发现最大支持 16GB RAM 的https://www.cnet.com/products/toshiba-satellite-c55dt-a5305-15-6-a6-5200-4-gb-ram-750-gb-hdd-us/和https://support.toshiba.com/supportmodel/PSCFWU-02000D（https://support.toshiba.com/support/staticContentDetail?contentId=4004241&isFromTOCLink=false）
笔记本电脑支持的最大内存正确是多少？笔记本电脑的型号是什么？谢谢。

答案1
根据您发布的内容，它看起来像：
- 您有 4GB 内存。
- 您有一台 Satellite C55Dt-A (PSCFWU)
- 因此您的笔记本电脑最多可容纳 16GB 内存。
但这取决于您发布的内容。我个人会信任 lshw，但即使您不信任，也可以得到明确的答案。
找到笔记本电脑底部的序列号并将其输入https://support.toshiba.com/。我相信它会告诉你你拥有的是什么型号。
