CPU laptop issue

hey...yesterday i've noticed an odd thing...been running Boinc on my acer laptop with T9600, it was always warm, fan was working above normal (running it at 100%), but nothing really critical...however starting yesterday fan began working less, less heat was generated and workunits suddenly took me twice or more as long....usually, for example, faah took me like 5 hours...now its 10-12:( i installed everest and found out that every time i close the lid or the monitor turns off, clock speed goes down A LOT....i dont understand, i know about speed step tech, however boinc is an active program, thus it shouldnt kill the CPU when its actually in use. also, obviously it wasnt doing this before, like i said, had much better results two days ago. please, any idea whats going on?

i just checked my 2nd laptop with T6570, also installed everest, let the monitor to turn off and it ALSO underclocked itself...i am really confused:(

edit: T9600 has win7, T6570 has vistas

Re: CPU laptop issue

Set both W7 and Vista in the Power Management control applet to something like Maximum Performance. BOINC is a lowest idle-priority level process, so some systems might interpret this as: ok, nothing in a rush, throttle down. I've fought that battle on my laptop when upgrading it from XP to W7 and it would not stay on high rev.

Re: CPU laptop issue

Several laptops I have looked at have a feature under power management>Advanced a setting for what to do "When I close the lid of my portable computer: " and a selection box. Among the choices in the select box, is "Do Nothing". You might want to take a look at that and see how it is set.
