Got a quote from a repair place that is more than the 18 month old Acer Chromebook C720 is worth. Thought I'd try to replace the DC power port myself. Is that doable? Thanks so much!

Acer Chromebook C720: Spilt water on keyboard, battery not working

Wed, 02 Oct 2019 13:50:26 -0700

I spilt water on my Acer C720p Chromebook recently (the c720p is the same as the c720 but with a touch screen) and everything works fine, except for the battery.

Initially the keyboard didn't work properly, some keys would press the ones next to them at the same time but this stopped after the computer dried properly.

But the problem is that now my Chromebook only works when it's plugged in and (at least according to the Chromebook) the battery never rises above a 1% charge.

I've tried reseting it, both by turning off developer mode and also with a powerwash option in the settings but no luck so far.

I've seen a couple of pretty good videos on replacing the battery on YouTube but I've heard from some tech friends that it could be caused by damage to the motherboard so that it doesn't recognise the battery rather than the battery itself. Any ideas?

Cheers! (:

Acer Chromebook C720: Wi-fi won't turn on on my Acer Chromebook

Thu, 05 Sep 2019 15:45:15 -0700

I have two Acer Chromebooks. A C720 and an Acer R11. Both developed an issue where the Wi-fi will not turn on. Both are out of warranty. I do not think it is a software issue.

The 720 will not accept any resets “An unexpected error has occurred . . .”

The R11 worked up until last week, but has developed this same problem with the Wi-Fi. Otherwise it was working just fine. There were no other issues and I’ve not tried to do a factory reset yet on the R11.

Any suggestions?
