HP Laptops Processor slowdowns

[jammers]

Hi All

 

Over the summer I installed the lasts bios firmware to a number of HP laptops. Since then staff have complained of the system slowing down to a crawl. To the point of hitting a key takes a few seconds for the letter to appear.

 

In the event logs a Kernel-processor power warning event 37 shows up

 

The speed of processor 1 in group 0 is being limited by system firmware. The processor has been in this reduced performance state for 71 seconds since the last report.

 

I've changed a number of the advanced power options, which has improved the problem, but staff still report the computers are slower than they were before the bios upgrade.

 

Has anyone had similar issues????????

The Machines are HP probook 6470b and 6360b. Windows 7 x64. Hp Bios Version F42

 

Thanks in advance

There is a later version of the BIOS F43. One of the fixes seems to indicate it a power issue. It might be worth updating it again. Edited October 15, 2013 by difinity
