Re: L390 has a hot cpu after sleep. please tell the l390 team

I tested the long sleep, over 1 night and the problem is still here.

 

when ''max power'' on AC  is set in the option of the terrible video driver by intel, the power package is at 8 Watts and when I choose ''battery optimized'' it drops to 2 Watts. not even below 1 watt.

 

All drivers and BIOS are up to date with ''system update''

Re: L390 has a hot cpu after sleep. please tell the l390 team

Hi,

 

I'm also facing the same issue ever since I bought the L390 in late Jun. Have already updated my BIOS/drivers via Lenovo Vantage but still the same. Can the support from Lenovo look into this and assist to resolve asap?

 

Thanks.

I hope that with 2 users, What laptop do you have with what cpu ?

 

 

there will be a reply from the team at lenovo. SO far there is zero communication on their parts.

 

I see a new BIOS  1.25  in system update so I will update it tomowrrow, to compare between the bioses.

So i updated my windows 1809 RSS% with all the updaes by microsoft. my new versions is Microsoft Windows [version 10.0.17763.805]

I updated my intel video driver to 26.20.100.7260 . I will test the long sleep tonight. My setting is that on AC powr, I have max power for the igpu

I let the computer sleep for 10 minutes with ''max performance'' for  the video card and the powr stays at 8 Watts. As soon as I choose ''balanced'' it goes back to 2 watts....

 

Given the refusal of the people at lenovo to help their client, I will create an issue on the forum by intel, linking to this thread.

Re: L390 has a hot cpu after sleep. please tell the l390 team

I installed BIOS 1.25, from BIOS 1.24 and video driver 26.20.100.7260 

 

-use ''max performance'' for ''ac power'' for intel video card

-reboot

-let idle

-go to sleep fro 1h30

-cpu is at 8 watts

-choose ''balanced'' for ''ac power'' for intel video card and cpu power is at 2 watts

 

then I did the same with 1 night of sleep

-use ''max performance'' for ''ac power'' for intel video card

-reboot

-idle

-sleep for 1 night

-cpu power is at 2 watts

 

I did these twice and so I do not understand why 1h30 of lseep makes the cpu hot.

 

I will try BIOS 1.25 and video driver 26.20.100.6999
