CF-29 MK-4 with low cpu speed

HI, I have just found a few MK-4's (5KKSA) CF-29'S that the bios shows 1.6ghz and the system properties shows 256mhz. The computer will at that time have hulu playing and will have lines in the video and it is running slow after I turn off the video player and try to do something else. Any Idea's>

Thanks Dale z

 

Are you sure the 256 is the clock speed and not the amount of ram (they are side by side in the info panel)

With 256 of ram it will be slow !

 

I am running 1.49gig ram showing and it will say 256MHZ , 595, 918 at different times..
I have found that I now have 8 doing it with 20 more in that ser# range still to look at.

Insufficient information here.

Please post the entire Model Number; such as CF-29Lxxxxxx.

 

That is the way Centrino works, it is the power management system that lowers the cpu speed.

You can set the laptop for best performance in the advanced tab.

 

Do a google search for Intel power management vs windows Xp power management. I don't have any exact links anymore. I read an article by an Intel engineer on how Microsoft didn't really trust Intel to do power management correctly and ignored what Intel told them. Windows power management and Intel's built into the cpu power management don't always play well together.
He suggested that you NEVER use the laptop power profile. He said use desktop or always on. Laptop apparently continually slows the cpu down the longer you have it running.

 

O.K. I'll jump in here. Be sure to check thermal pads as part of your diagnosis.

Good luck.

If I convert the one's I am keeping to W7 and run it in performance mode will that help?

I am going to start that on Tuesday and I will get back to you.

I think I will load W7 and I will do that with advanced tab.

I see that you found one of those 256/60 and loaded it with 2 gig stick. I just finished looking at 204 CF-29L & N's trying to find one.. NO luck.. I get one some time Because I am hooked on Toughbooks now and whats funny is I am Paid to play with them. Thanks again for the help.

I have the same model as you
And I am running @ 1.6.....most of the time lol
If you have installed all the optional software you have installed cpupower
Start/All programs/Panasonic/CPU Idle Setting
Check Battery -Windows standard

 

I will look into that..

Dale

 

If you do not have the utility:

Model Number: CF-29LAQGZBM
Operating System: Windows XP Pro
Release Date: 2005/8/22
CPU Idle setting software.
cpupower_29_4_d030520.exe (1142361 Bytes, English)

 

I have loaded it and Flashed the bios and install windows 7 on the troubled CF-29's and I see better running computers now.
Thanks
