The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Mysterious kernel panic

Asked by Scythy in Apple Laptop

Hello all,

I am working on a customers Powerbook G4 which has been shutting down. After a great deal of research and testing I have hit a wall as to what steps to take in determining the cause of this problem. I have tested the RAM with memtest, ran permissions repair, and run stress tests.

When I received the computer on Monday the very first thing that I noticed was the date and time were off by 30 years. I have corrected that and have not seen a switch back, so I am assuming the Bios battery is in functioning conditions. Since I have had the computer it has kernel panicked once, and I will be attaching that log. The customer threw away her installation disc, so I am unable to do a proper HDD check to see if there are bad sectors. However, the fact that I have been running a stress test over night with no freezing or crashing tells me that the HDD is functioning. (The stress test was having the computer playing Chess against itself at the highest difficulty. This causes a high load on the system due to the complex mathematical algorithms)

She need her computer back (or declared dead) by Sunday. Any help that you folks could give me would be greatly appreciated. Thank you in advance!
