Acer Chromebook CB3-431-C5EX 故障排除

no cursor on screen

Turn your computer off and then disconnect all media devices such as USB drives. Next disconnect the AC power adapter and then remove the battery. Perform a hard reboot by holding down the power button for 7 seconds. Finally, reconnect the AC power adapter and turn the computer on without the battery connected. IF the Chromebook starts up normally you have finished the hard reboot.

You can’t remove the battery on most Chromebooks; the unit is sealed so the battery is inaccessible, unless you’re suggesting dismantling the Chromebook and invalidating any warranty/insurance a user may have.

When I read the advise offered to liam hughes, who sees no cursor on screen, which suggests to remove the battery, I’m doubtful if there’s a chance to find a solution to my problem with this Acer Chromebook. The person who offers advise shouldn’t be that ignorant, assuming that a battery installed in this type Chromebook can be removed?

But I’ll give it a try. Since I’ve got a couple of external hard drives in use often and prefer to use a mouse as well, there’s not much room to plug them in, with only 1 USB portal.

Recently I’ve bought a USB hub with 4 portals, with a cable connected to my Chromebook with the other end in the USB hub. Plus a cable plugged in the USB hub and in the electric socket at the other end. The blue lights on the USB hub are on when I switch the buttons on ON. There’s no effect, it doesn’t show up on my Chromebook, do I have to download an app or extension, so that I can use the USB hub?

Is this service non-existent? Last time a comment was left was Sept. 15 2018. Hmm.

My Chromebook asked for an OS update with no other options. Now it won’t turn on, it keeps going to a screen that says “Your device is going through a critical update please do not shut off” or something like that, and it won’t go to another screen.
