lag after waking from sleep mode

asked 2018-12-18 13:32:11 -0600

I'm on Fedora 29 but this problem has been happening on every Fedora version I've used on this laptop.

At night I put the laptop to sleep and wake it up in the morning. I have to restart the laptop everytime because after every sleep the CPU is at 100% and it lags and is very slow but as soon as I restart the laptop it works fine and is back to normal. Anyone know how I can troubleshoot this and fix it?

laptop - Gateway NE56R34u, processor - Intel® Pentium(R) CPU B960 @ 2.20GHz × 2 , graphics - Intel® Sandybridge Mobile, 64 bit OS

One way to begin with will be:

  1. When you cpu at 100% after sleep -- switch to virtual console with Ctrl-Alt-F4 or F5 or F6

  2. Login

  3. Run sudo top and see which process (or processes) are taking all the cpu.

Then you'll be able to search for information about processes responsible and sleep.

it' a need to use power management and plz check upower

A. systemctl check two daemon upower and cpupower

# rpm -qa|grep upower
  upower-0.99.9-1.fc29.x86_64

# systemctl status upower

 upower.service - Daemon for power management
 Loaded: loaded (/usr/lib/systemd/system/upower.service; disabled; vendor preset: enabled)
 Active: active (running) since Wed 2018-12-19 11:59:43 KST; 3h 36min ago

12? 19 11:59:31 orion cpupower[1053]: Setting cpu: 1
12? 19 11:59:31 orion cpupower[1053]: Setting cpu: 2
12? 19 11:59:31 orion cpupower[1053]: Setting cpu: 3
12? 19 11:59:31 orion systemd[1]: Started Configure CPU power related settings

B. use System setting - Power management Most energy-related and power-related settings apply, and this behavior is either incomplete or affected by settings. Therefore, please set this part and let us know the operation status.

Have a nice day! written by simmon
