T61 clicking sound when on battery

[T-Pad]

Can anybody help??

Whenever I unplugged the power jack and running on battery,

My speakers keep on clicking whenever I click on something (like opening folders or browsing)

The sound gets bigger if I turned the volume up...

It's not the windows XP click sound, but it's a very annoying clicking sound..

Any ideas??

Sounds like some sort of grounding issue, have you reseated the battery?

I've tried that once, but still no luck...

I ussualy uses the battery until it gets into 10% or less..

So, I don't think I should reset it again...

But, thank you though...

I have the same problem on my T61. I had XP SP2 professional on it for six months or so without any problems, then re-imaged it with Win XP SP3 (new install). Since I get jitter mouse move, crackling/popping audio and jittey video. Something clashes every 3-4 seconds and every time it does, audio pops, mouse blocks and video skips. It lasts about 50 miliseconds, then it moves on fine.

I'm sure its the driver/bios compatibility issue, but I cant pinpoint yet what exactly.

this is actually the CPU that is clicking... this sound should eminate from the left side top corner of laptop where the CPU is at. A known problem in the Santa Rosa Core 2 Duo cpu... it has to do with CPU power management.
