Why is my CPU set to 598Mhz? I have a T42P

[SpunkyXL]

Hey,

I have a 1.8Ghz T42P laptop, and I was just checking my CPU speed, and for some reason it says 1.8 Ghz than next to it 598 Mhz. Why is that? I have the battery set to Max Performance, CPU - Max performance, and this is still occuring. I want my CPU always to be running at 1.8 Ghz.

That is because you got the battery manager set to maximize the battery life.

Try to set it to maximixe performance. It will set your processor to maximium speed.

I already have it set to MAX Performance.

I set it to Superpower saver to see what happens, and it set it to 197MHZ, I went back to MAX Performance, and is now set to 598MHZ.

Fixed it..went to BIOS and changed some settings

Why would you want your CPU to run at 1.8GHz all the time? Just pointless heat generation.

I agree setting the CPU to max processing power all the time wastes not only battery power when unplugged but also generates a lot of heat. This in turn has the potential to place a heavier strain and wear out your components faster. In the control panel window you will see an icon for power options then a folder menu of settings, under advanced settings you will see a pull down menu for CPU power management; automatic or disable. Windows warns you to leave it on auto unless you know what you are doing. If you are running just a word processor the CPU is usually on medium power, but if you multitask and run a few software at the same time you will notice the CPU setting increase until it hits the maximum clock speed.

it thought t42 is running @ 333mhz???

[dr_st]

The CPU runs at any various speeds between 600MHz and the max speed (1.6-2.1GHz). The multiplier that determines the speed can be fixed or selected dynamically depending on CPU load.

The FSB is quad-pumped 100MHz = 400MHz and the RAM is double rate 166 MHz = 333MHz.

in turn has the potential to place a heavier strain and wear out your components faster.

Do you have any actual evidence specifically related to T4x laptops in support of that assertion?
