Windows 7: BSOD when running laptop off battery power

BSOD when running laptop off battery power

About 4 months ago I performed a number of upgrades to my 4 year old Lenovo SL400 laptop.

I upgraded to a Seagate Momentus hybrid drive, upgraded my CPU, installed new RAM, purchased a new 9-cell battery and performed a clean intstall of Windows 7 Home Premium 64-bit (the computer came with Vista - Windows 7 was a retail upgrade).

I had several BSOD crashes which only happened when running on battery power. I was sure the battery was the culprit and RMA'd to the vendor for a replacement. I still have the issue with the replacement.

I notice a screen flicker a second or two before the crash. About half the time the computer recovers without crashing.

I've attached the dump files and system health report.

Any help would be greatly appreciated.

Thanks.

I saw the ThinkPad Display error in the 7-17 performance report so I uninstalled and reinstalled the driver for my display and I no longer have that error. I've attached an updated report.

Anyone have an idea what is causing my crashes? I'd love to be able to use this machine without being tethered to the plug.

I ran sfc /scannow and there were no integrity violations.

Can anyone point me in the right direction?

I just ran prime 95 for nearly 7 hours without a problem.

I'm not expert an bsod analysis (I'm not even an amateur) but I've looked at the dumps and igdkmd64.sys and athrx.sys are mentioned as possible cause.

igdkmd64.sys - Intel Graphics driver
athrx.sys - Atheros Network Driver

Have a look and see if you can find updated versions of the above drivers and see if it helps while you are waiting for somebody that understand this stuff to come along lol

I actually did update the Atheros driver about a week ago. The Lenovo site gave me a 2 year old athrx.sys driver but I was able to find one on the Atheros site from 2/23/12. I still get dumps pointing to that though. I'll see what I can find on the other. Thanks.

Did you check optional Windows Updates for newer drivers after your Clean Reinstall - Factory OEM Windows 7?

You may need to enable to Automatically get recommended drivers and updates for your hardware .

The reason I ask is that Windows 7 is nearly driver complete in the installer and then quickly updated via optional Updates. Only if these driver cause issues should drivers be changed with the latest from the OEM's Support Downloads webpage.

Looking at the Lenovo webpage for the SL400 model you list, it shows Realtek Ethernet and Intel Wireless drivers, no Atheros. So unless you've listed the wrong model I would double check the exact model against the drivers posted online for SL400 at Lenovo Support - Download Drivers and Software (US)

There are also several video drivers for that model listed, so I'd use the autodetect feature Lenovo offers to determine your drivers from it's tab on Lenovo Support - Download Drivers and Software (US)

If there is any question remaining, determine the exact hardware device using Hardware Identification.

Yes - I have Windows update set to retrieve drivers and icons for me. I did visit Intel's page and used their automatic driver update tool after installing the operating system. I only started hunting drivers as a way to solve my blue screen problem.

The Lenovo site shows Intel Wireless LAN and a couple of nameless wireless LANs.

I've attached a screen grab that shows my network adapters (including the Atheros wireless LAN).

Did you use the auto detect feature on the Lenovo page I linked above?

You want to try the Lenovo drivers first as they may have modified them. But there are a lot of drivers dumped in the Downloads webpage for the SL400 so you need to either refine the model number or use the autodetect so it will bring up your exact wireless and display driver.

If not trace the exact device used on your laptop using Hardware Identification

I don't see the autodetect feature on the Lenovo support page. I do have Lenovo Thinkvantage system update installed which I run periodically.

I'd gone into my device manager already and my wireless adapter is identified there as 11 b/g Wireless LAN Mini PCI Express Adapter III, Manufacturer: Qualcom Atheros Communications Inc. I used that info to select the driver from their website.
