CPU at 100% when lid is closed

Hi guys,

my CPU load is at a constant 99-100% when I close the lid of my D150 (I switched off "go to standby when lid is closed" in the energy options).

Have any of you experienced this problem too? What can I do about it? I read another topic in this forum where a faulty bluetooth driver is causing such loads (independent from lid status), but I'm only using the drivers that have been pre-installed on the device.

Thanks for any advice
Christian

 

Hey guys, can any of you who owns a D150 quickly check if you have the same problem? Thansk!

 

Sorry buddy I do not show these symptoms.

I am not running the default windows install so that is probably not much help to you.

 

my D150 also exhibits this issue. But doesn't affect me coz my setting is standby when lid is close.

 

I've got the same issue, it's a burden for me because I would like to leave it running closed. I wondered why the CPU fan was constantly running when lid closed, finally found this issue - closed=fan running, opened=silent, based on CPU load from System. This must be a bug and Acer should advise how to fix it.

 

What power feature settings are you running?

I have the following settings, when I close my lid my fan never turns on, and I get 12+ hours of usage by closing my lid when I'm not using my Acer. Upon opening the lid, it takes 12-15 seconds and I'm running where I left off, with up to an additional 10 seconds for wifi reconnection.

AOD150BLACK: I would really marvel if your fan would turn on while your computer is (almost) off. You've got Standby when the lid is closed, but we need it running closed. Standby = off, just RAM (and perhaps something else) powered.

 

I have this problem too... I would like my AOD150 to be able to run with the lid closed without hogging cpu (and thus getting warm and using up the battery too fast)

Im running win7 RC (7100) btw.

 

By the way, also another thread on this exists here:

viewtopic.php?f=59&t=11731

I was googling a bit about this issue and I've found some information on ACPI interrupt storm. Could our problem have something to do with this? Closed lid sending huge amount of ACPI interrupts eating up CPU time?

 

Has anyone found the solution already?

 

I just downloaded BIOS v1.09 and it appears to have fixed this problem.

 

I can confirm this on win7!

 

BIOS upgrade to version 1.11 also resolved this issue.
