From b349f258a99d4e56e875b7dbf86fa2368d196a41 Mon Sep 17 00:00:00 2001 From: Jeremy Soller Date: Mon, 20 Jul 2020 15:19:30 -0600 Subject: [PATCH] mb/system76/lemp9: update power limits MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Tested on lemp9, power limits are adjusted from the previously low values to the values the thermal system can handle. This was determined by increasing the values and running the system at 100% CPU utilization until thermal throttling occured and the chassis temperature became uncomfortable.
