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

2009-10-28, 10:46 AM

Based on the experiences of the thread on switchable graphics driver issues under Vista, I start here a new one for switchable graphics issues related to Windows 7 (all SKUs). Please keep the thread focused and your language clean. That is: Issues related to XP or Vista are not the topic here. :smileyhappy:

 

I made the switch to Win 7 64 and so far, it's an improvement in the "switchable graphics"-area. But I've already observed some issues:

  •  Power consumption is much higher than under Vista 32. It seems related to a problem in the power management of the switchable graphics adapters: See the thread by roteiro.
  • On my external Dell monitor, I observe occasionally "pixel noise". In some areas of the screen pixels flicker in different colors.
  • Might be related: Hang after resuming from standby

Re: R400/T400/T500/W500: Switchable graphics issues with Win 7 - FIXED AT LAST?

2010-11-16, 15:05 PM

All,

 

We've just released new drivers and they can be downloaded on the following links.   These are for Windows 7, 32 and 64 bit and are appropriates for the switchable graphics eqipped models of R400/T400/T500/W500.

 

I am interested in feedback on these to confirm they resolve the power management concerns after resuming from suspend, and they should also ensure the on screen brightness feature works correctly.

 

[Problem fixes]
- Fixed an issue where the power consumption increased after resuming normal
  operation from sleep state.
- Fixed an issue where the LCD had blank screen after resuming normal operation
  from sleep state by opening the lid.

UPDATE:  I'm moving all the feedback on the new drivers to a new thread because the original issue has been solved by the drivers linked here.   We need to collect feedback on new symptoms and pursue resolution for those.

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

My W500 running W7/64 RTM.  Installed W7 switchable driver posted mid-October.  My native resolution is 1900x1200.

 

 

When running in reduced resolution on the ATI card, I cannot enable "Full Screen" mode - all options give "Centered" display - with blank border around the display area.  But on the integrated Intel, I can stretch to fill the display.

 

 

Reverting to April Vista drivers, and "Full Screen" works again with the ATI card.

 

 

Strange, but when 2nd monitor is attached, I *can* enable "Full Screen" on the ATI - and stretch lower resoltions to take the full display.

 

 

Anyone else?  Any known fix?

Running into significant power consumption issues, as per the @roteiro thread mentioned above.  On wake-up, I'm running double-wattage drain.  Switching to and from the "High Performance" option causes this to drop back to normal wattage.  (I think...)

In the event log, I have many errors like the following ones:

 

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

 

If this is only noise, then the error entries should not be created.

Another small issue with the switchable graphics drivers under Windows 7 is that the color reproduction is slightly different when using discrete graphics compared to using integrated graphics. Notice that this issue is also present in the Vista drivers.

I would not call it "slightly" different, for me they are really annoying (too bright colors on integrated) - but only if you are on battery.

What fixes the problem to a certain amount is disabling some of the power-saving features within Intel's Display Settings tool.

 

Greetz!

So, at the very least there is another user who made the same observation!

Hehe, same feeling here ; )

Once I had a Lenovo technician take a look at my machine and convinced him to do something about this problem, so he changed the mainboard - no effect. Don't know what causes it, but changing the graphics settings makes it endurable.

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

HELP! !

 

My W500 display crashed when I scrolling web pages in IE easily.  About 10 times an hour in average.

Sometimes it stopped responding even when the "Disply driver stopped responding and has recovered!" windows balloon didn't disappear.

 

OS is Windows 7 x64. version 6.1.7600.16385

 

 I don't know if there is any connection between the scrolling action and the display driver failure .    Except when  reading web pages in IE ,  display driver worked perfectly when other application was running.

 

If I switched to intel graphics, everything went smoothly. I have installed the newest display driver from lenovo.   But it didn't help.  There is  no external monitor  attached.  It's a newly installed OS,  so I can rule out application confliction.  I wonder if this is a hardware failure, or I'll have it changed.

 

here is some messages from my windows   System log

 

Every time the display driver stopped responding, 2 messages were added to Windows log.

 

firstly

Error :Display is not active

 Secondly

 lzmi, would you please shed some light on me how to solving this problem? Using Intel Graphic?
