alexaffonso Posted September 26, 2010 Share Posted September 26, 2010 Hello to you all! I'm having an issue I don't know how to solve at all. Everything's working fine on my Vostro 1500 Snow leopard 10.6.4 except for a few details. One that is bothering me so much occurs when I use my laptop on battery. It's a 2.06 GHz Intel Core 2 Duo processor, but when it's not plugged to a power source, eg: it's running on battery, the "About This Mac" shows it's a 1.1 GHz Intel Core 2 Duo and it actually has a lower performance. Is there anyone who knows about it? How to solve problem? I'll be glad if you can help me, again! Thanks a lot. Alex Quote Link to comment Share on other sites More sharing options...

alexaffonso Posted September 28, 2010 Author Share Posted September 28, 2010 Turn off speedstep in bios maybe Dellmant, it's not SpeedStep which's addressing this issue. I tried to deactivate it but the strange behavior doesn't go away. But I noticed something different with such tests. Actually, when I turn on my machine with battery on, the "About My Mac" says it's a 1.1 GHz Intel Core 2 Duo. I just need to reboot the machine and the info gets back to it's correct values, eg: 2.01 GHz Intel Core 2 Duo. I can't figure out what's going on. What happens when I reboot my system so it reads the correct info from my CPU? Anyone has an idea? Thanks a lot. Quote Link to comment Share on other sites More sharing options...

Have you checked the logs? Energy saver settings? Seems like something to do with power management. Any third party kexts to do with power management? sleep?

The Kexts I'm using that has something to do with power management are: NullCPUPowerManagement Voodoo Battery Is it possible they're causing me troubles? Is it safe to exclude them or should I replace them with some others? Quote Link to comment Share on other sites More sharing options...

If it is correct after reboot then something is happening later, so that should show in your logs. Do you know if it is a consistent time that it happens after a restart?

There's nothing on Energy Saver settings regarding processor speeds. Quote Link to comment Share on other sites More sharing options...
