I installed the test kernel: linux-headers-5.0.0-28_5.0.0-28.29~lp1840835_all.deb linux-headers-5.0.0-28-generic_5.0.0-28.29~lp1840835_amd64.deb linux-image-unsigned-5.0.0-28-generic_5.0.0-28.29~lp1840835_amd64.deb linux-modules-5.0.0-28-generic_5.0.0-28.29~lp1840835_amd64.deb linux-modules-extra-5.0.0-28-generic_5.0.0-28.29~lp1840835_amd64.deb
uname -r: 5.0.0-28-generic Power consumption was completely normal, idling at less than 4 watts as expected. While using iGPU, I noticed that each time I run lspci, it lags for less than a second and the following messages appear on dmesg: [ 7.587195] snd_hda_codec_hdmi hdaudioC1D0: Unable to sync register 0x7f0800. -5 [ 7.587200] snd_hda_codec_hdmi hdaudioC1D0: HDMI: invalid ELD buf size -1 On file dmesg50028 I provide the dmesg output. I switch to nvidia gpu for test purposes. Everything is normal, and those messages only appear at gpu initialization, and lspci didnt lag at all. On file dmesg50028nvidia I provide the dmesg output after switching to nvidia gpu. Excluding those messages, I conclude that it fixes the power consumption problem. ** Attachment added: "dmesg50028" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1840835/+attachment/5285032/+files/dmesg50028 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1840835 Title: High power consumption using 5.0.0-25-generic Status in linux package in Ubuntu: Incomplete Bug description: After updating to 5.0.0-25-generic kernel, battery life is considerably less and power consumption is about 10 watts more idle, using integrated graphics. This is a hybrid GPU laptop Intel HD 630/GP107M, and a possible cause is not powering off the dedicated GPU completely while using the integrated. nvidia-driver-430 GP107M [GeForce GTX 1050 Mobile] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1840835/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
