System crash but no log.

Hi everyone

I suspect my Macbook Pro6.2 (mid 2010) is having the NVIDIA crash problem, however, it is hard to investigate as no log of the crash seems to be generated. Here’s what happens:

Screen goes black, keyboard back light on.

Restarts with the multilingual ‘press any key to restart’ message.

Restart continues, grey screen, Apple logo, progress bar, but then at about 10% progress, it restarts again.

When the restart has completed, I open Consul and no kernel panic report, no entries in System Diagnostic Reports at all.

So my questions to you guys are:

Is the ‘double’ restart normal? and why no panic report?

Thanks in advance.

Cheers from London!

Try these instructions to log and post the kernel panic:

The 6.2 model identifier MBP had a replacement program for defective GPU's. That program has expired.

I suspect that may be the reason that your MBP is having problems.

If I am correct, the solution is to have the logic board replaced ( at your expense).

A temporary solution is to use this application that will allow you to disengage the discrete GPU and run with only the ionegrated one:

This will be at the expense of graphics performance.

Thanks Ogelthorpe. The switcher app looks worth a try.

As to the crash reports, I have already checked the /Library/Logs/DiagnosticReprts folder and as I said, no reports exist. This is what is puzzling me - every time a kernel panic happens nothing gets logged. I would really like to fix THIS problem so I can use the reports to solve the NVDIA problem.

Cheers.

In view of that situation, you can make an appointment at an Apple store genius bar and have them test the MBP. Be sure to tell them that you want to test for this specific problem because there is a specific test that is run. Note that this evaluation will be done for FREE.

Ciao.
