Chromebook - Battery Problems

Continuing problems with Chromebook battery not charging. Need new battery, or...?

A Hardware Reset will disconnect the battery briefly, so it accomplished the same thing as physically unplugging it.

Simply pushing the power button, or rebooting, does not remove the trickle charge that keeps the embedded controller (EC) running. A hard reset drops all power to the EC, so when the power comes back on it goes through a reinitialization. Since the EC controls the keyboard, touchpad, battery and all other on-board peripherals, performing this it can potentially fix a wide range of problems.

The procedure is detailed on this web page. Some devices require specific steps, but most newer devices only require a simple keyboard sequence. 

Hard reset your Chromebook - for most Chromebooks, follow the steps below:

 - Turn off your Chromebook.
 - Press and hold Refresh  + tap Power . 
 - When your Chromebook starts up, release Refresh.

If the procedure to reset your hardware does not work, you may have a hardware failure.  First, move everything to another plug in your house, in a different room. If that doesn't work, does your charger light come on?  If you have access to a duplicate charger, try the other charger. If that doesn't work, contact your manufacturer for a warranty claim or out of warranty service.

 

Back to your issue -- Battery Test

We have to figure out if you have a bad battery, or if something else is going on.

 - Open a Crosh Shell (ctrl alt t)
 - Type "battery_test" and wait 5 minutes for the test to complete and then copy/paste the output when you reply. 

Many users cause their batteries to fail prematurely by allowing them to go completely dead before recharging. Modern lithium batteries, like the one in your Chromebook, do not like being discharged completely. Each time that happens, damage is done, until it fails completely.  Also, they cannot be overcharged like old technology NiCad batteries. So, follow the approach that many of us experts take - keep your Chromebook plugged in all the time, unless you need to use it while mobile.

If the battery tests OK, then you have a bad charger, a bad charging cable, or a damaged charger port.
