I've recently bought an Acer laptop with a AMD Athlon XP-M 2400+
processor running XP home. When I start the laptop from battery using
the "laptop power scheme" the processor speed in XP system properties
shows as 487Mhz. Running "PC-Wizard" is shows the processor frequency
as 786Mhz. If I start the laptop with AC power and change the power
scheme to "normal" then XP reads as 786Mhz and running a process
benchmark in pc-wizard is gives the frequency as 1786Mhz. I've tried
altering the power scheme but can't get it to show any higher but
reading on AMD website the 2400+ should have a speed of about 2Ghz.

The bios does show the processor as being a 2400+.

Obviously I don't need it to run at full speed all the time but would
like to know if the processor can work at the speed it should do.

My sister has a laptop (different make and model though) with a Athlon
2000+ which gives a maximum speed of 1.66Ghz so surely mine can go
higher?

Any suggestions would be appreciated.

I have one with an AMD XP-M 1600+. I've noticed that, too -- but the
computer is running at normal speed.

I'd not give it a second thought.

I think it might be to do with the processor changing it's processor speed
(if it's like the intel ones) contiunously to save power - if it's something
it still does when on AC power, then it's going to confuse any benchmarks,
but would still go at full speed if it needed to. Just a guess.

There is no problem. Go to AMD's site and download their little
dashboard application that shows in real time what is happening to the
CPU frequency as your activity changes. It's an interesting display of
load management by AMD.

My Fujitsu also runs at 1/2 speed when on battery - this is normal.

Can I get on the wagon here? On my ThinkPad A31p with 1.7 GB, it will
only run at 1.2 GB when the battery is not installed, according to
AIDA32. Any suggestions? TIA.
