# Computers
Each computer has its own information and related hardware (monitor, components, etc.). All this information is divided into tabs. You can find your computers in **Assets > Computers**:
{% hint style="success" %}
Note that if you modify a field manually, it will be considered locked. This will prevent it from being modified the next time the automatic inventory is uploaded.
For more information, see [lock](https://github.com/glpi-network/gitbook/blob/main/manual/modules/assets/broken-reference/README.md)
{% endhint %}
