From bfe0c53fc37aa44bc9a6b69e5105126556f8bf7c Mon Sep 17 00:00:00 2001 From: Dave Parker Date: Fri, 20 Jun 2014 10:08:46 -0700 Subject: Rambi: Increase adapter input current limit to 1894mA This sets the adapter current limit to 90% of the rating for a 40W adapter. The earlier limit was based on a 33W adapter which was not used. BUG=chrome-os-partner:23833 BRANCH=ToT TEST=With a 20-80% charged battery run 4000 fish (search for WebGl Aquarium) with backlight at 100%. Verify ChargerCurrent is around the limit with 'adc' command on EC serial console.
