Intel Sandy Bridge Cougar Point Design Flaw?

2013-02-20, 13:08 PM

As also posted at the IdeaPad Y, U, V, Z and P series Laptops section, The Sandy Bridge Cougar Point design flaw "involves a a an Intel Series 6 support chip, code-named Cougar Point, that interacts with SATA-linked devices such as the hard drive and optical drive. On several of a system’s SATA ports, faulty metal on the chip  can cause  the signal to degrade over time, leading to errors, reduced speeds, and eventually an inability to read or write from that port.   The problem is undetectable on a new motherboard and only appears on a small percentage of systems – Intel says around 5 percent – over a period of weeks, months, or years."

 

More information : http://blogs.intel.com/technology/2011/01/chipset_design_flaw/

 

Does this design flaw impact the X220(Tablet) series? As far as I can tell from http://www.intel.com/support/chipsets/6/sb/CS-032521.htm , "mobile systems using the Intel® HM67 and HM65 may be affected by this issue". The X220T uses QM67, does this mean it is not affected?

 

Better be safe than sorry... ;)

At the time when this came out the platform was few months out already. The affected systems (that used specific ports) were recalled. I don't remember any Thinkpads being affected and/or recalled at the time.

Thank you for the link! I guess my search query (intel sandy bridge cougar point) was too specific. Plus, I searched in the ThinkPad X Series Tablet specific section. ;)
