本教程涵盖Chromebook(Chromebooks)上触摸板和鼠标问题的故障排除修复。如果 Chromebook 的触控板或触摸板无法正常工作，请使用触摸屏或外接鼠标尝试这些修复方法。
1.清洁触摸板
如果触摸板上有污垢、灰尘或液体，Chromebook 的光标可能会冻结或闪烁。使用干净、干燥且不起毛的布擦拭触摸板可能会使其再次正常工作。
如果使用外接鼠标，请确保它位于平坦、无尘且光滑的表面上。将鼠标放在鼠标垫上使用（如果有的话）。
当电池电量不足或耗尽时，外接鼠标有时会发生故障。检查鼠标的电池电量，如果电量不足，请充电。如果电池不再充电或过早耗尽，请更换电池。
2. 在触摸板(Touchpad)上敲击你的手指
用手指在 Chromebook 的触摸板上轻轻敲击以产生鼓声效果。这样做至少 10 秒钟可以去除粘在触摸板周围或下方的灰尘或颗粒。
3.调整触摸板速度
在触控板上移动手指时，Chromebook 的光标是否过于敏感或反应迟钝？(cursor too sensitive)在触摸板设置菜单中调整(Adjust)光标/指针速度。
转到Settings > Device > Touchpad，然后将“触摸板(Touchpad)速度”或“鼠标(Mouse)速度”滑块移动到您的偏好。
4.启用点击点击
点击Chromebook的触控板相当于按下物理鼠标的左键。如果您的Chromebook在您点击触摸板时没有选择项目，这可能是因为“点击点击”功能被禁用。
转到Settings > Device > Touchpad，然后启用“点击点击”。
5.更改触摸板加速设置(Change Touchpad Acceleration Settings)
触摸板(Touchpad)加速增强了 Chromebook 的光标移动，并允许您快速滚动页面。启用触摸板加速可以解决Chromebook 上的
光标或鼠标滞后问题。(cursor or mouse lag issues)
打开“设置”(Settings)应用，在侧边栏上选择“设备”，选择“(Device)触摸板(Touchpad)”，然后打开“启用(Enable)触摸板加速”。
6. 改变滚动类型
在ChromeOS中，当您用两根手指向上滑动触摸板时，“反向滚动”会将页面向下移动，反之亦然。禁用沿滚动方向移动页面的功能——即，当您向上滚动时页面向上移动，当您向下滚动时页面向下移动。
转到Settings > Device > Touchpad并关闭启用反向滚动以禁用反向滚动。
7.启用点击拖动
“ Tap-dragging ”允许您通过在触摸板上双击并拖动手指来移动或选择多个项目。如果您的Chromebook(Chromebook)禁用了点按拖动功能，则您无法使用触摸板拖动或移动项目。
转到Settings > Device > Touchpad并启用“启用点击拖动”。
8.反复按Esc键
多次按Esc键也可以解决(Esc)Chromebook上的触摸板问题。反复点击Chromebook的Esc键 20-30 秒，然后检查您的触摸板或鼠标现在是否可以使用。
9. 重启你的 Chromebook
按住Chromebook的电源(Power)按钮，然后在电源菜单上选择关机。(Shut)等待(Wait)2-3 分钟让您的Chromebook关闭，然后按电源(Power)按钮将其重新打开。
10. 更新您的 Chromebook
更新您的 Chromebook 可能会解决触摸板问题，尤其是当其操作系统比最新版本落后几个版本时。
将您的Chromebook连接到Wi-Fi或以太网(Ethernet)，打开“设置”(Settings)应用，然后在边栏上选择“关于ChromeOS ”。
等待(Wait)Chromebook下载最新的 ChromeOS 版本，然后选择重新(Chromebook)启动(Restart)以安装更新。
如果您使用学校或公司的Chromebook，您可能需要联系您的管理员更新其操作系统。
11.执行硬重置
如果尝试上述修复后触摸板仍然无法工作，请重置Chromebook的硬件。(Chromebook)硬件重置（也称为嵌入式控制器(Embedded Controller)重置或 EC 重置）会重启Chromebook的键盘(keyboard)、触摸板、端口、电池等。
硬件或 EC 重置过程会因您的Chromebook类型或型号而异。请注意，执行重置硬件可能会删除“下载”文件夹中的一些文件。我们建议将该文件夹中的文件备份到Google 云端硬盘(Google Drive)或 USB 拇指驱动器。
此外，在重置硬件之前，请从 Chromebook 上

Chromebook Touchpad or Mouse Not Working? 13 Fixes to Try
This tutorial covеrs troublеshоoting fixes for touchpad and mouse problems on Chromebooks. Use your touchscreen or external mouse to try these fixes if your Chromebook’s trackpad or touchpad isn’t working.
1. Clean Your Touchpad
Your Chromebook’s cursor may freeze or flicker if there’s dirt, dust, or liquid on the touchpad. Wiping your touchpad with a clean, dry, and lint-free cloth might get it working correctly again.
If using an external mouse, ensure it’s on a flat, dirt-free, and smooth surface. Place and use the mouse on a mousepad if you have one.
External mice sometimes malfunction when their batteries get low or die. Check your mouse’s battery level and charge it if low. Replace the batteries if they no longer hold a charge or die prematurely.
2. Drumroll Your Fingers on the Touchpad
Gently tap your fingers on your Chromebook’s touchpad to create a drumroll effect. Doing that for at least 10 seconds could dislodge dirt or particles stuck around or underneath your touchpad.
3. Adjust Touchpad Speed
Is your Chromebook’s cursor too sensitive or sluggish when moving your finger on the trackpad? Adjust your cursor/pointer speed in the touchpad settings menu.
Go to Settings > Device > Touchpad and move the Touchpad speed or Mouse speed slider to your preference.
4. Enable Tap-to-Click
Tapping your Chromebook’s touchpad is equivalent to pressing the left button on a physical mouse. If your Chromebook doesn’t select items when you tap the touchpad, that’s likely because “Tap-to-click” is disabled.
Go to Settings > Device > Touchpad and toggle on Enable tap-to-click.
5. Change Touchpad Acceleration Settings
Touchpad acceleration enhances your Chromebook’s cursor movement and allows you to scroll pages quickly. Enabling touchpad acceleration can resolve cursor or mouse lag issues on your Chromebook.
Open the Settings app, select Device on the sidebar, choose Touchpad, and turn on Enable touchpad acceleration.
6. Change Scrolling Type
In ChromeOS, “Reverse Scrolling” moves a page down when you swipe up your touchpad with two fingers and vice versa. Disable the feature to move pages in your scroll direction—i.e., pages move up when you scroll up and down when you scroll down.
Go to Settings > Device > Touchpad and toggle off Enable reverse scrolling to disable reverse scrolling.
7. Enable Tap Dragging
“Tap-dragging” allows you to move or select multiple items by double-tapping and dragging your finger on the touchpad. You can’t drag or move items using your touchpad if tap-dragging is disabled on your Chromebook.
Go to Settings > Device > Touchpad and toggle on Enable tap dragging.
8. Press the Esc Key Repeatedly
Pressing the Esc key several times can also fix touchpad problems on your Chromebook. Tap your Chromebook’s Esc key repeatedly for 20-30 seconds and check if your touchpad or mouse now works.
9. Reboot Your Chromebook
Press and hold your Chromebook’s Power button and select Shut down on the power menu. Wait 2-3 minutes for your Chromebook to shut down and press the Power button to turn it back on.
10. Update Your Chromebook
Updating your Chromebook might resolve touchpad issues, especially if its operating system is several versions behind the latest version.
Connect your Chromebook to Wi-Fi or Ethernet, open the Settings app, and select About ChromeOS on the sidebar.
Wait while your Chromebook downloads the latest ChromeOS version and select Restart to install the update.
If you use a school or work Chromebook, you may need to contact your administrator to update its operating system.
11. Perform a Hard Reset
Reset your Chromebook’s hardware if your touchpad still doesn’t work after trying the fixes above. A hardware reset (also called Embedded Controller reset or EC reset) restarts your Chromebook’s keyboard, touchpad, ports, battery, etc.
The hardware or EC reset process will vary depending on your Chromebook type or model. Note that performing resetting your hardware might delete some files in the “Downloads” folder. We recommend backing up files in that folder to Google Drive or a USB thumb drive.
Also, unplug devices and accessories (monitor, power cable, USB drive, mouse, etc.) from your Chromebook before resetting its hardware.
Reset a Chromebook Laptop’s Hardware
- Turn off your Chromebook and wait 10-30 seconds for it to shut down.
- Press and hold the Refresh key and tap the Power button.
- Release the Refresh key when your Chromebook boots.
Reset a 2-in-1 Chromebook or ChromeOS Tablet
- Turn off your Chromebook and wait 10-30 seconds for it to shut down.
- Press the Volume Up and Power buttons for at least 10 seconds.
- Release both buttons when your Chromebook starts up.
Reset Chromebooks with Removable Batteries
You can restart a Chromebook’s hardware by removing and reinserting its battery. If your Chromebook battery is detachable, turn it off, and remove the battery. Wait for 1-2 minutes, reconnect the battery, and turn your Chromebook back on.
Reset a Chromebit
To reset a ChromeOS-powered Chromebit, turn it off, remove its power adapter, and wait several seconds. Reconnect the power adapter, turn on the Chromebit, and check if the paired keyboard works correctly.
Use a Special Reset Button
Some Chromebooks from Lenovo, Samsung, Acer, and Asus have a reset button typically hidden in a hole in the bottom case. Turn off your Chromebook, remove its power adapter, and press a pin, paperclip, or SIM card ejector down the hole.
Hold the pin or paper clip and reconnect the power adapter. Turn on your Chromebook and remove the paper clip when the display comes on.
12. Use Guest Mode or Re-add Your Account
Your Chromebook’s touchpad might malfunction if there’s a problem with your account. Using your Chromebook in guest mode can help determine if your account has a problem with the touchpad.
If there’s more than one account on your Chromebook, delete and re-add the account that doesn’t work with your touchpad. Perform a factory reset if you use just one account on your Chromebook.
- Reboot your Chromebook and select Browse as Guest in the bottom corner of the sign-in screen.
Note: You won’t find the “Browse as Guest” option on your work or school Chromebook if your administrator disabled guest browsing. Contact your administrator to re-enable guest browsing on your Chromebook.
- Select the time in the bottom-right corner of your screen and select Exit guest on the system tray.
If your touchpad works in guest mode, delete and re-add your account to your Chromebook.
- Open the ChromeOS system tray and select Sign Out.
- Select the arrow icon next to the account name and select Remove account.
- Select Add person on the sign-in page and follow the on-screen instructions to re-add the account.
13. Powerwash Your Chromebook
Factory resetting or powerwashing your Chromebook wipes everything on your built-in storage. Backup your files to Google Drive or an external hard drive before performing a factory reset.
Note: You might be unable to factory reset a work or school Chromebook. Contact your administrator to wipe your Chromebook and re-enroll it on your school or work network.
Powerwash Chromebook from the Settings Menu
Go to Settings > Advanced > Reset settings and select the Reset button.
