小新-15 2020（AMD 平台：ARE 版）是聯想發布的基於 AMD Renoir 的筆記本電腦。該款電腦主要在中國大陸銷售，最相似的國際版型號為 IdeaPad 5 15ARE。

## UEFI

在安裝 Arch Linux 之前，請關閉 BIOS 中的 Secure Boot。在開機第一屏按 `F2` 就能夠進入 BIOS，按 `F12` 能夠進入啟動菜單。

您可以在這裡找到 BIOS 的更新：小新-15 2020(AMD平台：ARE版) 驅動列表 的 BIOS 欄目下，提供了一個 Windows 安裝程序。 使用 innoextract (1.8 版本經過測試) 來提取下載的 BIOS-E7CN39WW.exe 中的 E7CN39WW.exe，這是 Phoneix 的 BIOS 安裝器，但是它不能用 innoextract 再次提取。

### Noto Button

您也可以使用 "Noto Boot Menu"， 它相比於 BIOS 和 啟動菜單提供了更多的選項。在開機狀態下，按 `Fn + <電源鍵>`來啟動它。詳細信息參見官方用戶手冊小新-15ARE用戶指南。

### F2 和 F12 keys 無法使用

Windows 20H2 安裝器（消費者版本，更新於2021年2月）經測試會刪除這些按鍵進入 BIOS 設置和啟動菜單的功能。這是微軟有意為之還是只是 Windows 的一個 bug 仍然不明。目前 (2021年3月3日），這個型號的筆記本仍然在保修期內，您可以找官方售後恢復主板的 BIOS 信息。

目前的建議是：如果您想要安裝 Windows, 請使用低版本，如 1903。 我沒有測試過 Windows 中的大版本更新，請小心更新。如果可能的話，不要多重引導 Windows。

詳細信息參見 UEFI#Windows changes boot order。

## 處理器

小新-15 2020（AMD 平台：ARE 版） 包含一個 AMD Ryzen APU。您可以按如下方式提取精確型號：

    $ lscpu | awk -F ": *" '/Model name/{print $NF}'

    AMD Ryzen 7 4800U with Radeon Graphics

    $ lspci | awk -F ": *" '/VGA compatible controller/{print $NF}'

    Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c1)

### CPU

強烈推薦啟用專有微碼更新，詳細信息參見 Ryzen 和 Microcode。可通過如下方式驗證已經成功啟用了微碼更新：

### GPU

Xorg 可與當前的 linux包 和 xf86-video-amdgpu包一起正常運行。

## 聲音

聲音與 Linux 中的 PulseAudio 兼容，開箱即用。

## 網絡連接

### 無線控制器

無線控制器開箱即用，詳細信息參見Network configuration/Wireless。

    $ lspci | awk -F ": *" '/Network controller/{print $NF}'

### 藍牙控制器

開箱即用，詳細信息參見藍牙。

    $ lsusb

    ...

## 音頻

開箱即用, 詳細信息參見 Sound system。

    $ lspci | grep Audio | awk -F ": *" '{$1=$2="";print $0}'

    Advanced Micro Devices, Inc. [AMD] Family 17h (Models 10h-1fh) HD Audio Controller

## 觸控板

觸控板在大多數時候開箱不可用。 您需要先將其從 `elants_i2c` 解綁，然後再將其綁定到 `i2c_hid` 。

提示：切換到 root 用戶運行如下命令 (sudo su), 因為普通用戶即使用 sudo 也沒有權限

    $ modprobe i2c_hid
    # echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/elants_i2c/unbind
    # echo "i2c-ELAN0001:00" > /sys/bus/i2c/drivers/i2c_hid/bind

現在需要將 `elants_i2c` 模塊加入黑名單，因此你不必每次都解綁、綁定。

    # echo "blacklist elants_i2c" | tee /etc/modprobe.d/touchpad.conf

注意，觸控板可能仍無法正常運行並伴隨如下的錯誤信息：

    Mar 03 21:50:14 localhost.localdomain kernel: i2c_hid i2c-ELAN0001:00: HID over i2c has not been provided an Int IRQ
    Mar 03 21:50:14 localhost.localdomain kernel: i2c_hid: probe of i2c-ELAN0001:00 failed with error -22

這種情況下，移除 `i2c_hid` 並重新加載它：

    # rmmod i2c_hid
    # modprobe i2c_hid
