Re: R400/T400/T500/W500: Switchable graphics issues with Win 7

2010-09-17, 8:26 AM

what versions did you end up with?

 

CI have a W500 with the fireGL adapter (effectively a tweaked 3600) and since the Lenovo drivers are unacceptably out of date (had known fixed issues) I'm currently running with 10.8 "on top" of the old integrated drivers. End result is support for switchable graphics but with 2 glitches

 a) The intel drivers are still old 

 b) which switching works after boot/login, at some point afterwards it stops working. In particular I get an error indicating that 3d is in use, though even after shutting down all potential apps (like chrome, firefox with their new acceleratino support) I cannot clear without a logout/in

 

I suspect b) is not related to the specific drivers I'm using, but anything's possible.

For me, turning off desktop composition fixed some video problems.  (Right click affected program -> properties -> compatibility -> disable desktop composition). Not a true fix, but made the machine usable while we wait for Lenovo to deliver what they sold us.

Re: R400/T400/T500/W500: Switchable graphics issues with Win 7

I had downloaded, from the ATI site 10.8 and I had downloaded, from lenovo, Intel 4500MHD (Intel GM45 Express Chip) v 8.15.10.2182

 

win update, then downloaded updates for both of these and installed. 

 

 however, in device manager, I see differently so I am not really sure what I have!

 

In Dev Mgr, in the drivers tab for both the video adapters:  ATI Mobility Radeon HD3650 and Intel 4 Series Express chipset, It reports the same driver... ATI driver ver 8.641.1.1000 (8-24-2009).

 

If I were to select driver details on the driver tab for each one, I see the many different drivers from the two vendors Intel and AMD (or ATI)

 

I guess this is not very helpful...

 

I can say that my machine has become, in general,  much more stable.  I have had two blue screens occurances during reboot after installing some software.  no reason was reported in event viewer. it has not happened since though either. 

 

and I did have a critical thermal event shut down my notebook 1 time last week...

Izmi, 

 

don't know if you still see the event viewer errors..

 

Error    26.10.2009 19:02:08    amdkmdag    43029    (42): Display is not active

Error    26.10.2009 19:02:08    amdkmdag    52236    (51): CPLIB :: General - Invalid Parameter

 

I came across a post that said to update directX to fix that and that has seemed to work for me.  I have not seen those errors since and I was seeing both several times a day. 

 

Tha last DirectX update was in June.

Hi dmoss11,

 

I also get these error messages but I think that they are harmless. Let's hope that the new drivers will fix all these things in one sweep! - At least this is what I think Lenovo can accomplish! :-)

Hi Izmi,

 

The drivers has been delayed due to issues during test. We are yet to get a date from engineering on when the drivers will be released. Will update once we receive news.

followed these today...loot of rebooting headaches and all..

 

So, it now give me two options to switch graphics (from the desktop right click and from the power manager right click). But the old Lenovo drivers did this too.

I was hoping this would fix the wake from sleep power problem, but it doesn't.

 

monitoring wattage drawn by the battery (under the lenovo power manager)

bios set to integrated without switching ~13W before and after going to sleep

bios set to discreet without switching ~16-17W before and after going to sleep

Bios set to switching, selecting high powered(discreet) from windows ~17W before and after going to sleep

 

but here's the kicker:

Bios set to switching, selecting low powered(integrated) from windows, ~13W before, but after goign to sleep and waking up... ~23W

This indicates that both graphic adapters are getting power, even though only one shows up in the device manager.

If I follow this with a switch to discreet, and then a switch back to integrated (without going to sleep), then I can get it back down to 13W. If I let it go to sleep and wake up, boom, back to 23W.  

 

This power increase does not happen if I put it to sleep when switched to discreet (~17W before and after)

 

Super annoying problem. Lenovo, when will you fix this?!

Hi All,

 

Appreciate everyone's patience on this however we have still not been provided a tentative date on when the drivers will be released. Will update everyone once we have a date on this.

joer80,

 

Two years?  No, this problem relates specifically to Windows 7 which came out at the end of October 2009 so it's coming up on 11 months.  It just feels like it's been two years.  Or, maybe this is two years in web time. :smileywink:

 

Honestly, we had a target of the end of August for new drivers, but there were some additional problems found in test.   It shouldn't be, but it's complicated in that we are trying to test and keep synchronized, drivers from Intel and AMD/ATI.   If there are issues associated with either side at a particular level, we are back on hold until we get the next update.

 

I understand this is our responsibility to get this addressed, and I apologize that this had become such a long running issue.  Perhaps almost as much as you, I would like to see us reach the finish line on this.  Jamez is doing some really solid work here in the forum and getting a lot of these older issues followed up and closed out, and speeding up the qualification and esclation of issues on some of the newer products.

 

Best regards,

 

Mark
