Precisely what I've have observed.

They designed it that way and they are not telling consumers.  That's fraud.

Does it have a VGA connector too which would also imply that it's a desktop
replacement?  It's NOT!

Precisely,  Intel has covered itself by including right in its Pentium M
spec sheet that the user community expects continuous full performance when
AC powered.

Larger format laptops I've checked seem NOT to suffer from this.

I'm afraid they are all doin this in ultracompacts...you know the laws of
physics and all.

Are all the above large format laptops?

Thanks, I'l add the T41p and T42p to this list of offenders.

The industry has to start telling folks before some AG gets hold of this.

I'm a staunch industry supporter and that is why this kind of thing must be
stomped out immediately!

Anyone know about the Dell Latitude X300?

NOTE that I strongly support these neat ultracompacts and TabletPCs as they
have a great place in the industry but THEY MUST NOT BE SOLD AS DESKTOP
REPLACEMENTS as they now are.  That's fraud!
