I have two laptops. HP nc6400 and tc4400. Both has Intel 945GM graphics
adapter with the same amount of display memory. Both the has 512M of RAM.
Only diff is tc4400 is a tablet and nc6400 is not.
Aero Glass works on nc6400 but not on tc4400.

What's up?

Is it broken on tabletPC????
 
If you have Visat RC2 , go to end of this msg - otherwise read all..

You will have to ask the maker of those machines, HP or Intel Corp.

Nobody here can explain that, because Vista is obviously working on one
machine, so if you use the very same DVD and have not changed anything, e.g
have running the same services etc ( Ultimate has tablet Features built in,
regardless if it is installed on a physic tablet or a Desktop or whatever
PC ), than it must have to do with a hardware-difference.

There are different Intel 9xx GM adapters, that go by nearly the same name,
but ARE different, some use memory from the main RAM , others have RAM on
the card alone, etc..

Check that out, like I said consult the manuals or HPs Support.

I do not think it's Vista.Except the following :

----------------------------------
----------------------------------
----------------------------------
If you use RC2 ( 5744) - it has a bug on spme machines to not enable AERO.

------------------
## First Step of Two :
Click to expand...
------------------

go to regedit ( as Admin ) :

HKCU/Software/Microsoft/Windows/DWM and set the following :

"Composition" if 0 set to 1
"CompositionPolicy" set it to 2
---------------------------------
## Second :
Click to expand...
-----------

open a commandprompt as Admin and type in :

net stop uxsms

hit Enter, this stops the Desktop Window Manager

net start uxsms
-------------
this resarts it and you should have Aero turned on instantly, if your Card
does support it.

On unknown or unsupported cards these settings will do nothing but a
flickering, but wont let you get Aero.

Actually it should not currently work on either of your systems as you
have described them.

Aero requires 128MB (or more) of VIDEO memory, and vista requires 512MB
(or more) of SYSTEM memory. The 945GM is a "shared memory" chipset ...
video memory is "stolen" from system memory. So the minimum memory to
run Vista (even without Aero) on this shared memory chipset should be
128+512MB = 640MB ... and with 512MB or less, even vista basic should
not run, much less aero, because video memory can never be zero.

AS A PRACTICAL MATTER, since the 945 supports dual channel memory, you
really don't want to run with less than 1GB. Smaller amounts of memory
are physically possible, but would use two modules of different sizes,
causing the chipset to revert to single channel memory operation. So
what you really want to do is change the memory (in both machines) two
two architecturally identical modules of 512MB each (that is, 1GB total
in each machine).

I can't explain why you are seeing what you are seeing, but the 945GM is
supposed to be capable of running Aero Glass .... but not with the
memory configuration that you say that you have in either machine.
 
I doubt that. I notices a change in the Builds :

Vista Builds higher than Beta2 / 5536up do a check before Setup, and
examine if you have exact or above 512 RAM, if you are under setup will tell
you that it cannot install Vista, becasue you do not meet the requirements
of memory.

Even the Starter Version does this initial-check.

So, if we assume he has only maybe 512 minus 64 ( or 32 .. ) for the
Grafiks or so
than how the Heck did he manage to run setup ?

There is no way to run setup.exe with a paramter to not test the ram.
CPU does not matter, Vista even installs on 500 MhZ, my guess is that is for
the laptop users, as certain laptops do throttle the CPU Clock down to
nothing to save power when no intensive programs are running.

So to say the CPU check is disabled to not accidently tell a 2,4GhZ mobile
User "your system is too slow" only because he is running in powersave mode
;-)

Would be too much for the support.

Anyway, maybe he can tell what ControlPanel --> System is telling about the
Hardware or too be more informative :

open a commandprompt and type in

Systeminfo

that clears pretty much everything, oe needs to know.

Thanks. I will try your suggestions.

I have tried both Ultimate and Business and got the same result. nc6400
works but tc4400 does not. Everything about the computer is the same except
one being a tablet and the other is not. I was guessing the tablet extension
broke the display interface.
BTY... I am using 5744 build.

The registry setting that you have indicated, is that forcing Vista into
Aero? If not, is there a way to force Aero?

Thanks.

That is RC2, and it has the described bug. So maybe it is the fault. Try my
workaround, usually it helps.

Yes.

These settings are the Key for Aero. But do not forget to "net stop uxsms"
and "net start uxsms" - this needs also to be done for the registry to have
the effect.
 
Thanks... That worked out great... :-)
