I do have a Aspire E5-573G-387K Notebook.
I've been using this for an Year. Working fine. Recently I did have a clean installation of my Windows 10. So I came to acer support to download drivers. There I find many BIOS updates for the Model I'm having is available. Some of them are denoted as providing improvement in System performance. I'm now in a bit of confusion which on i could download and install. Am I have to download em all and install one by one or download the last updated verison and install only that. I dont wanna brick my beloved lappy at this moment. Thanks in advance.
