Counterintuitive Chromebook

Posted on: October 16, 2016

In a previous reflection, I noted how there seemed to be a phantom power draw by my Toshiba 2 Chromebook when I used it in presentation and facilitation mode.

The lowered battery life seemed to be due to my use of an HDMI-to-VGA dongle to project my screen during workshops. This was odd given how the Chromebook was a relatively passive device.

Recently I used my Chromebook for 6.5 hours straight in active use. I was grading learner performance with Google Forms and fact-checking in Chrome. I did this over a day in one morning and one afternoon session. I still had a little over two hours of battery life left when I responded to email at a cafe later.

All this seems is counterintuitive: Use the device passively to project the screen and the battery runs out, but use it actively and it is an all-workday device.

The difference is the HDMI dongle which seems to sap battery life. I estimate it reduces battery life in my Chromebook Toshiba 2 by about half.
