Hi,



Thank you for writing to Microsoft Community Forums.



We understand your concern with the battery report. Active State Power Management or ASPM is a power management protocol used to manage PCI Express-based serial link devices as links become less active over time. It is normally used on laptops and
other mobile Internet devices to extend battery life.



In order to get clarity and to assist you accordingly, please reply with the answers to the questions below.

• What is the make and model of the PC?

Fingerprint issue/Power Management

already tried the credentials service one, not of any help. I guess the only fix is from the power management tab

1. Press Windows Key + X and choose Device Manager from the list

2. When Device Manager opens, locate your fingerprint reader. It should be located in Biometric Devices section.

3.Right click your fingerprint reader and choose Properties

4. Navigate to Power Management tab and uncheck Allow the computer to turn off this device to save power.

5. Click OK to save changes.


I want to follow this step but I cannot find the power management tab.

 

Is AHCI enabled?

Hi Shumitra,

Thank you for posting your query in Microsoft community.

I understand your concern and will guide you in the right direction.

Windows uses AHCI (Advanced Host Controller Interface) by default, but it may not be enabled if your BIOS wasn't set properly during installation of the operating system.

Follow the steps below to check if ACHI is enabled properly.

a. Press Windows + X.

b. Select Device manager.

c. Click the arrow next to "IDE ATA/ATAPI Controllers" to display the list of controller drivers currently used by your system.

d. Check for an entry that contains the acronym "AHCI." If an entry exists, and there is no yellow exclamation mark or red "X" over it, then AHCI mode is properly enabled. If
you don't see an "AHCI" entry, or the only entry contains a red or yellow mark, then there's a problem and AHCI mode is not properly enabled.

Hope this information helps. Please let me know if you need further assistance.
