at first, i thought that maybe my optical mouse is an old one, so it may not be compatible with the chromebook.
then i tried it with another optical mouse, when i plug it in, it still doesn’t show the light under the mouse. it will work if i restart the chromebook.
one time, i unplugged the usb mouse, then plugged it in again. it stopped working. it doesn’t happen all the time though.
after i restart the chromebook, the mouse will work again. it has happened probably everyday when i use it.
today, i tried to plug in a usb external hard drive, after the mouse stopped working, somehow the chromebook can still recognize the external hard drive.
this is a refurbished chromebook. is there something wrong with this usb port？ i already updated the chromebook to the latest version.
