Hyperthreading...

Hyperthreading, if indeed your CPU is capable of it (some of the P4 3.06 were not) must be enabled in the bios first. Check in the "system" properties - control panel, device manager. If you have hyper-threading it will show you having two processors.

how do i enable it my bios?i dont see an option...maybe because the driver wont install. besides when i upgraded my bios to a38. several options became locked.

You would have had to purchase the notebook specifically with hyper-threading in order for it to work. That was at the CPU level I think. There was a bios flash that enabled it - I think it was a24 - you are way beyond that. If you don't see anything in your bios for it and the software download won't execute, and you see only one CPU in your system devices, I'm 99% sure you don't and /or can't have hyper-threading on that machine with that chipset and CPU. The change to hyper-threading came about during the life of the 5150's so there were both flavors sold.

i see one.

so your saying that even if i had hyperthreading and it was disabled...i would still see 2 cpus in performance ect...?

If the option isn't there in BIOS setup, the CPU does not support it.

The 3.06 mobile was available in HT and non-HT formats (unlike the 3.06 desktop P4, all of which were HT).

no, you will only see the two CPUs if it is working ... i was just wondering how many you saw
