Changed battery on Chromebook won't charge

I changed the battery successful from one that was not functioning to one that is really great and performs well. However, the battery is not charging at all.

The Chromebook will retain the 60% of power that came with the new battery; it will use the power adapter as a source when the latter is plugged in.. But the battery itself won’t increase from 60%. It will just drain when not plugged in, but not charge.

The power jack was acting a little weird before any of this (had to be at a perfect angle to charge). I bought a new ac adapter. It has the exact same problem. If it’s not at the perfect angle, it won’t charge my computer.

I’m wondering if the battery issue is not connected to the power jack issue. I have a feeling they are, but I have no idea how to even begin to diagnose the problem or to fix it.

Any good questions or answers are very welcome! :)

A good way to check the health of your Chromebook battery is to use the Crosh utility. To open up Crosh, press ctrl + alt + t on your keyboard.

When Crosh opens, type battery_test at the crosh> prompt. This will start the battery health test. Since your battery is new, the health grade should be almost perfect. If it isn’t, then the battery will need to be replaced soon, if not refunded (if it is in fact refundable).

The power jack of the Acer Chromebook CB3-111-C8UB is soldered onto the motherboard, and is therefore difficult to replace. You could buy a whole new motherboard, but the whole process (motherboard, tools, shipping costs) may end up costing more than the laptop itself.

what would the battery grade need to be though?

Michael Roach さんによる2021年4月3日

In this case, it should be okay to "guestimate" instead of determining an exact percentage. The user was trying to see if the symptoms were because of the battery or the charging cord. A 60% charging capacity is so low that there is little room for considering incremental differences in the battery grade percentage. It's okay to use the battery test as a general reference when expecting extremes in the results. Trying a "known good" battery is the most fool-proof method, but before spending all that money, testing it first can help with making a more informed choice.
