Why does my laptop slow down after waking up?

Question

System administration

Laptop Lenovo G50-30, Windows 10. Proc Intel Pentium N3540
After exiting standby or hibernation with a certain chance, the laptop wakes up terribly slow. A cursory glance at the task manager shows as if the processor frequency is set to the maximum. And when it's 0.49GHz - and when it's 1.49GHz. Sometimes it is 2.14GHz.
In general, the native frequency is 2.66 GHz.
How to be? There was no such problem on ubuntu/xubuntu.
upd: on windows 7 this was not the case either

1. Try to fall asleep / wake up with the charging connected and compare the difference.

3 .Update the BIOS.
4. Update all drivers
5. Write to the TP of the laptop manufacturer

Answer 2

I run into this problem all the time. Just finish the job.

Answer 3

check, just in case, the power saving settings.
very similar to it, especially the jumping frequency.
set everything to "maximum performance"
Look in the bios for the power-saving setting of the processor (or whatever it is called correctly, something like automatically adjust the frequency)
