PowerPlay causes driver crash when power supply is unplugged X700 Mobility Vista 64

Dear all,

facing this issue on my Acer Aspire 5020 (has X200M chipset PLUS X700M Grafics on top):

When powerplay is enabled in the CCC, the driver crashes when I unplug the mains.
Screen goes blank and Vista (64 bit) tries to reload the driver, showing a mouse cursor for a while but fails, blank screen again. This goes into a loop until I plug the power back in and after a while it shows the desktop, flooded with messages 'the ...driver has crashed and was restored' or sth like that.

This happens with Cat. 7.6 and 7.7 (modded for installation with MobilityModder).

Pretty bad, Vista is anyhow reducing the battery runtime by 50% on this machine and any means to avoid this like PowerPlay would be great.

Can anyone share their experience with powerplay under Vista 64 (and X700)?

My apologies for the double posting, I put this first with Vista driver issues but I'm not sure where this should be put in the end.

I have somewhat of a similar problem, but on WinXP and Linux, on my MSI laptop also with a X700M and X200M.

Graphical corruption when changing to battery, or powering on and starting on battery, and the OS eventually crashes. Have to restart and use power from the plug. This is all with Powerplay on. If it is disabled everything is ok.

I'm using the latest drivers for XP but with Powerplay disabled which is really a shame.
I remember some older drivers worked ok, the one's from msi and ati's cat5.3 or something... don't remember correctly.

I know if you also have this problem in XP?

hi kmolazz, good to know that I'm not the only one with this issue.

sorry right now I can't test this with XP.
On this notebook I never saw powerplay working, but have never tried it with XP though.

may I ask you the following:
have you ever tried to install the south bridge driver package from ati ? does this package install anything on your machine? when I use it under Vista, nothing is installed except for a north bridge filter driver, however no sb driver.
not sure if this is related but I could imagine that an old south bridge driver could cause such problems, too.

what's the exact name/ type of your machine? actually I'm looking for notebooks that are similar to mine because I'm still missing a good solution for a driver which controls the special keys. I only have a workaround.
