    I'm having a problem with my NX9420. Recently I've notice it running extremely slow, but only on AC power. When power is connected the Task Manager in Windows lives at 90% to 100% cpu usage. I'm concerned because the slow down in noticeable before Windows loads. I'm dual booted with a Linux distro and ever the bootloader is extremely slow to load on AC power. Changing the boot loader choice by using the arrow keys is slow.... I'm running the latest BIOS and have had the issue before the BOIS update. I've also just (today) replaced the system board for a different issue.

    Any thoughts?
