sensor test - northbridge error 08 Dec 2015 21:43 #6931

hi,

my macbook 15" mid 2010, it hangs sometimes, so I tested it with techtool 9.

it found one problem:

northbridge (MCP) Vcore 0,28 v failed

it would be great, if techtool would tell more about every sensor and what to do, if the result is failed.

thanks to google I see, that northbridge is the main controller, whicht connects wo GPU, usb, etc..

so there is no easy solution, I have to replace the logic board?

thanks! regards, ferdinand

Thanks for providing the precise description of the error found by TechTool Pro 9.

I discussed your case with the beta administrator for TechTool Pro and, as I thought he would, he suggested that you bring the MacBook to an Apple Store and have them run Apple Service Diagnostics. In some cases, a component is failing, beginning to fail, or intermittent based on temperature (it may work properly when it is relatively cool, or relatively warm, but not both).

In my experience, Apple Service Diagnostics is run overnight, and the Apple Store staff are happier if you have made a complete backup before you bring in the computer.

It would be helpful to bring the test results from TechTool Pro to the Apple Store.

Hi there! It has been a year and a half since the original poster and was wondering if TTP had any info to add to this error at this time as I am experiencing the very same results.

Good question.

I will ask the beta administrator for TechTool Pro if his recommendation in my first reply in this thread still stands, and if he has anything to add.

The beta administrator for TechTool Pro recommends that you visit your local Apple Store or Apple Service Provider to confirm the issue. He also recommends that you have a recent backup of your data in case the Macintosh fails to power up when it is turned on.
