U350 + W7 + Lenovo Energy drivers - causing crashes at system hybernation or resume

Hello,

 

I bought a Lenovo U350 with Vista preinstalled. I installed Windows 7. I noticed that system randomly crashed during hybernation or resume process: after about half an hour of trying to "hybernate" or "resume", the system forces a shutdown.

 

I performed a clean install of Windows and tried to isolate the problematic driver (one driver every 2-4 days, performing lots of sleeps and hybernations in between). The problem occurs ONLY if the Lenovo Energy drivers are installed (IN1EGC02WW5.exe)

 

The issue is that without "energy" drivers, I can't use ambient light sensor and bluetooth, since the Fn+F5 key interface doesn't work.

 

The following is logged in system log:

 

 

Log Name:      System
Source:        Microsoft-Windows-WER-SystemErrorReporting
Date:          6.11.2009 21:05:17
Event ID:      1001
Task Category: None
Level:         Error
Keywords:      Classic
User:          N/A
Computer:      Nix.xxx
Description:
The computer has rebooted from a bugcheck.  The bugcheck was: 0x0000009f (0x00000003, 0x85295030, 0x8078adb0, 0x84d90f00). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 110609-21918-01.
Is there a solution to this issue?

 

Thank you,

Ziga Dolhar

Indeed. Current drivers (http://consumersupport.lenovo.com/en/DriversDownloads/drivers_show_1814.html) are declared as for W7.

 

It would also be welcome if Lenovo would provide their standing on this issue.

Is there any chance Lenovo would comment on this issue? :-/

Did the rest of the drivers and other Fn key combinations are working as expected?

 

Iam about to receive my Win 7 upgrade DVD soon, and I'm excited.

Hi dolhartz,

Welcome to Lenovo Forum!

Thanks for your posting and i am impressed with your patience to help iron out the possible root cause of the issue.

 

System crash is very serious and I know another forum member pak has reported the same. I would like to collect some machine info from you for escalation and get engineeres to look into it.

 

  • OS (e.g. win 7 ultimate, 64bit)
  • Machine Type Model (e.g. 7660-14A)

 

Thanks for pointing this out!

 

Regards,

Cleo

Cleo, thank you for your attention.

 

OS: Windows 7 32bit, Ultimate, in English

MO: QB09081121 (I hope this is the number you seek, written just next to the serial number)

 

If there is interest, I can provide the minidump file.

 

Yours, Ziga Dolhar

I use to have this exact sam problem.  I downloaded the latest video card drivers from the Lenovo website for the U350 and installed the latest Synaptic drivers from synaptics.com and the problem went completely away!

 

I also have a U350 with W7 64bit.

Hi dolharz,

 

Sorry for late response. Anyway, I guess that is not the machine type model. Is yours Type 2963? You can check at the white printed label at the back of your notebook.

 

Cheers,

Cleo

Cleo,

 

I took the photo of the white label and am sending it to you by way of a separate private message. I think this should be the easiest way to determine the number you seek Smiley Happy.

 

In the meantime, I (again) installed the supspect problematic driver this monday. Thus far, the computer has not crashed a single time. However, the difference this time is that I have NOT enabled the ALS (ambient light sensor) control, which I did previously. 

 

I will continue to have it off for the next few days just to be sure; then, I'll have it turned on and see if the crashes return.
