Hi all,

I have cb3-111-c8ub which is not charging properly. I have replaced with new battery but same effect. I have another acer chromebook which charges fine with same ac adapter.

cb3-111 battery charging icon blinks constantly when pluged in to ac adapter and does not charge. when I press it very firmly, it charges but once released it stops charging. Definitely some loose connection. I can open it up and replace any other parts as needed but not sure which part is causing this problem. Appreciate any help.

Thanks.

    Unfortunately it looks as if the DC jack is soldered to the mainboard, so not really an easily replaced part. Make sure the center pin is still in good shape, not bent or broken. There's a spring piece that pushes against the outside of the barrel and if it's broken you might not be getting good contact without side pressure.

    I end up ordering an used motherboard from ebay. Lets see if it resolves the issue.

    Is there another way to charge the Acer say, UBS PORT?

    Nope, a USB port uses different voltage.

    Could try this as well. A hard reset: press "refresh" button and on/off button at the same time. It fixed my problem not charging cb3 111 chromebook.
