  • Hi R3fr4cti0n,

     

    According to the Power Efficiency Diagnostics Report you provided, a Bluetooth adapter and a USB device could not enter the suspend state and the processor power management might be prevented. In addition, this report indicates the display timeout is long. You may update the BIOS and customize the power plan to improve the performance.

     

    For more information, you may refer to the following link:

     

    http://support.microsoft.com/kb/976034/

     

    In fact, there are two types for each power plan on a laptop. What I mean is that the power saver mode will be automatically adjusted when switching between AC power or battery power. For example, under Balanced (recommended) power plan, there are two methods for both AC power and battery power. Laptops will detect the power connection and automatically assign the proper power plan to balance the power and performance.

     

    Good luck!

  •  Thank you Arthur,

    I have googled how to both "update Bios" and how to get my "bluetooth usb device" to enter suspended state  both have no relevant results to help me accomplish this. So how do fix these problems? Also i understand how to get a power efficiency diagnostics report, as your link refers to and i understand how to read one. What i am having problems with is how to fix what is on the report. There seems to be no HowTo for the "Analysis Results" on  "USB Suspend:USB Device not Entering Suspend" or anything else listed. Is there such a HowTo or Microsoft sight that has this information?

  • Hi R3fr4cti0n,

     

    An outdated BIOS may cause some potential and unexpected compatibility issues. Since BIOS versions vary among different motherboards, I suggest contacting the manufacturer to upgrade the BIOS to the latest version. It will enhance the compatibility and stability of your system.

     

    Updating the BIOS may fix the issues regarding sleep. If not, you need to contact the related hardware manufacturers to check if they are fully compatible with the current hardware and software configuration. You may also install the latest version of the drivers to check the issue.

     

    For your reference, I find another link for you to optimize Windows 7 for better performance below.
