Windows 7: BSOD when laptop is sleeping

- x64 professional Windows 7
- clean installation of full retail version
- lenovo T500 bought in Jan 2010

My laptop restarts itself and crashes in sleep mode.
It happened before and was solved here in the forum but the problem came back.



Thank you!!!

Welcome
Your reports are consistent, they point to two possible causes
One Memory
Take a memory test with memtest86
http://www.geekstogo.com/forum/topic...ing-memtest86/

This driver was also given as a cause. Update
Iastor.sys file description
Productname:Intel Matrix Storage Manager driver
Description:Intel Matrix Storage Manager driver
Company:Intel Corporation

Thank you Richard, I just finished memtest and there was no error. My Intel Matrix Storage driver is already the latest version and it did not cause problems before. What else can I do to fix the BSOD problems?
Thanks!

Your reports were rather clear, I would make a system restore point then roll back the driver. If you still get the BSODs, give me the new report.

Hold on, the memory test should be 8 hours at least. You have to make 8 passes then test each slot for 8 morre passes.

Oh, ok, then I guess I only passed the first one.
will do it tonight.
Thanks!

Just take your time
Run it for 8 passes. Pass or fail, you must test each slot for 6-8 passes. Good luck

So the complete memory test turned out no errors found, and I removed the latest intel driver and install the previous version. Since then I've still got about 2 BSODs.
Please check this new attachment.
Thank you very much for helping!!!

Its the same driver again. iastor. Roll back to earlier version.
In a few days, I will not be able to read the dump reports for a while, but will be here to answer questions.

Thank you for the instant reply!
