Acer Aspire 7535g Windows 7 Upgrade run through

This is my noob experience of the £699 4 months ago 17.3" multi spec't acer aspire model 7535g

ATI mobilty 4570 radeon twin graphcs job

£12.78 buys two discs to get me from vista 32 home premium to windows 7 home premium 32bit

1 upgrade disc and 1 windows 7 media disc

I decide to go with a clean install so i changed boot sequence in bios to cd first, then booted from the windows 7 media disc.

option 2 custom install i managed to delete partitions which made my restore discs effectivley scrap.

realizing there was no way back, i had to instal windows 7

all went silky smooth untill the device radeon 4000 series had code 10 cannot start

i let windows 7 update this device - rebooted...the screen never came back...the machine was ON,signal up and everything but no raster, just a mouse curser.

hmm... rebooted in safe mode, rolled back driver....screen ok but still the graphics 4570 is code 10 and cannot start.

so i inserted the acer upgrade dvd
and ran all EXCEPT the amd puma driver
rebooted
all ok
then i ran the puma driver, rebooted and the screen never came on...backlighting but no picture.

Holding down the power button i just turned it off, rebooted, pressed f7 or 8 whatever key for safe mode and chose
ENABLE LOW-RESOLUTION VIDEO (640x480)
enter...
starting windows...4/3 aspect

right click - screen resolution
change to 1600 x 900 (recommended)
no more errors

All is ok, do you you guys know if i should i download the 9.6mb's of the 3200 ati driver that windows 7 is wanting me too?

I did let windows install the 9.6mb update with no problems and i have never installed any catalyst drivers from ati's website.

I am impressed with windows7 and glad i performed the upgrade.
current windows experience for my aspire 7535g is:

processor 4.9
ram 5.5
graphics 3.8
gaming 5.0
hdd 5.9

overall 3.8

Current graphics driver 29/07/2009
8.634.0.0

Superten - sounds like Windows is benchmarking the HD3200 rather than the HD4570, with a score of 3.8 for graphics. The laptop should switch between the graphics chipsets depending on if its plugged into the mains or not. Since upgrading to Windows 7, I've had no luck getting it to run with the HD4570 - it just won't switch over to it, and playing WoW at 15fps sucks big time, when Vista was playing it at 30fps with everything set to max.

It seems everyone is having this problem. Windows 7 just won't let the 4570 work - ATI PowerExpress is meant to switch between the two graphics cards.

If anyone comes up with a solution let us know?

Thanks.

Strangerer and strangerer. Windows downloaded a new driver for the HD3200 last night via the Windows Update service. It's 9.6mb in size. Since downloading that, and restarting the computer, the HD3200 seems to have dropped off the radar in Catalyst and I've only got the one display now, run by the HD4570.

The HD3200 is showing up fine in the Device Manager, but the computer still isn't switching between them when I plug/unplug the mains. The fact that it's now running on the HD4570, and I can play games again, has pacified me and hell of a lot, though. I can live with it now, even with the 1.5 hour battery life.

Oh, forgot to mention, when I use ATI PowerXpress, the Current active Graphics Processing Unit box is empty, although the icon shown is the chip 'n' battery, implying it's using the power-saving GPU. Checking the box for "Automatically select power-saving GPU when on battery" does nothing - the checkbox clears when you hit OK/Apply, and clicking the 'High-performance GPU' and 'Power-saving GPU' buttons does nothing much.

A few people have reported success getting the higher powered GPU to work. I don't know how you managed it, but I've also got to the same kind of stage as you (no Power Xpress but running on 4570 instead of 3200). I've detailed how I did it in: Radeon Mobility HD 4570 Not working after win 7 upgrade

If anyone wants to try it, let me know if it works. Might be interesting for you thundercat as it might explain why yours is working if you did something similar without realising.

I've kind of figured out what's been going wrong, but I have no idea WHY it's doing it. I think we'll have to just wait for ATI or Acer to launch a more Windows 7 friendly catalyst control centre and Power Xpress.

Are you saying that you got a clean install upgrade of Win7 on your Acer uising only the Win7 upgrade media disk, and NOT using the second disk they provide which has drivers, apps and bloatware?

If you are not using the apps disk, are you able to get Works and those apps you want some other way?

I realize Win7 installer is very good with drivers, followed up by Windows Updates with more, but what I am trying to understand is if these manufacturers' upgrades can be completely clean installed without bloatware while still getting the apps like Works which one might want.
