Do you want general information or information specific to your
system?

If things like Google searches don't help with answers, we can look up
your hardware information for you after you:

Click Start, Run and in the box enter:

msinfo32

Click OK, and when the System Summary info appears, click Edit, Select
All, Copy and then paste

There will be some personal information (like System Name and User
Name), and whatever appears to
be private information to you, just delete from the pasted
information.

This will minimize back and forth Q&A and eliminate guesswork and
assumptions.

LPC = Low Pin Count bus from Southbridge to SuperI/O chip.

Look for references to "1A30" in here. See PDF page 43.
