Как я могу знать, сколько RAM я могу обновить свой ноутбук?

Question 1

У меня есть Acer (Стремитесь E1-431), ноутбук. который я хотел бы увеличить RAM. Идеально я хотел бы иметь 4 ГБ, но я понятия не имею, как проверить, могли ли аппаратные средства поддерживать это расширение.

Question 2

Другой способ проверить макс. способность RAM с dmidecode:

sudo dmidecode -t memory

вывод будет выглядеть примерно так:

Handle 0x000A, DMI type 16, 15 bytes
Physical Memory Array
    Location: System Board Or Motherboard
    Use: System Memory
    Error Correction Type: None
    Maximum Capacity: 2 GB    <---- look for this line
    Error Information Handle: Not Provided
    Number Of Devices: 2

Question 3

Question 4

Движение к веб-сайт Accer можно искать устройство его порядковым номером, который в выводе находится в первом разделе serial: NXM8VSI0013090643D7620. На следующей странице переходят в , Сведения о продукте затем вводят Ваш серийный номер снова, и Вы будете взяты к спецификациям для того ноутбука. Это показывает, что Ваша макс. память составляет 8 ГБ.

Question 5

В целом, в терминале (ctrl-alt-t для запуска одного) выполняет команду:

sudo dmidecode | more

и взгляд на "Массив Физической памяти", который должен сказать Вам максимальную способность и количество устройств для системной памяти.
