Spent an hour or two replacing a battery into a ~7 year old Chromebook - ASUS C302CA. This has been my daily interface to the Internet and has done, and is still doing, such a great job that a $75 upgrade to a new battery seemed like a good bet.
Have gone from 2 to 3 hrs of battery life back to around 8 hrs. Awesome.
Can highly rate thinking about keeping ageing tech alive if it's still fit for purpose. Better than just chucking it out and replacing.
I got an Acer C730, its almost ten years old but its still running and doing everything I need it to do. I've replaced the charger 3 times but not the battery since its always plugged in. I will be sad when it dies but for $125 I couldnt have asked for more.
I love the whole Chromebook platform. Not sure if the Acer C730 runs Linux - the ASUS does.
Having, effectively, 3 OS's built in, ChromeOS, Android, and Linux makes the platform super usable. I mostly work at the Debian command line, right on the ASUS or shell into various servers. Being able to install Gimp etc., locally or run them off a server via X-Windows makes such a simple, and affordable device so flexible.
The ASUS has just run out of supported updates, but I don't think that is going to be too much of a problem for a while. Hope Google don't change ChromeOS any time soon...
