Hi @kitkat21996 ,
Are you using a wireless mouse with a USB dongle or a Bluetooth mouse?
If using the one with a dongle, is the dongle the correct one for the mouse and is it showing that it is powered on when plugged into the USB port?
If you are using a Bluetooth mouse and if you have Win 10 installed (you didn't specify), check in Device Manager on the status of the Bluetooth Network Adapter. (quick way to Device Manager is to right click on the Windows Start button - left side of Taskbar, and then click on the Device Manager link that appears in the options box).
If there is a red cross next to the Bluetooth entry, right click on the entry and select enable this device and see if the BT mouse then works.
If there is a yellow exclamation mark next to the BT entry, right click on the entry and select Properties > Update Driver .
This is where you can update the drivers to see if this resolves the problem
Here is a link to the latest Asus Win 10 drivers for your laptop. Download the drivers relevant to your particular BT adapter, (see Device Manager listing for make and model info).
See the Note near the top of the webpage regarding installation of the drivers.
