Slow when charging battery

Hello

This is a strange problem I encounter with my Sony Vaio FS laptop. When it works on battery power, it goes at full speed. When I connect AC power, the system slows down; for example the kernel boots a lot slower. When in framebuffer, you can also clearly see the cursor slows blinks slower.

I tried using sonypid but it doesn't help. I also don't see any errors in dmesg.

What could be the cause of this? I guess something built into the kernel is causing it. Maybe I should configure one manually.

Re: Slow when charging battery

Do you have some weird settings for laptop-mode-tools? Maybe sony reports charging as using battery instead of AC ?

Afaik I don't have that installed. It's simple, when you plug in the AC adapter it slows down significantly.

Note, the CPU speed stays the same all the time.

Re: Slow when charging battery

Maybe something's off in your BIOS. Check the power settings there. Are you using APM, or ACPI?
