i just bought a T410S and used a couple days. everything is ok except that there is very annoying high frequency noise (sounds like zzzzzzz).
i did a little research and it turned out this noise is coming from CPU while it alternates frequency.
when i change Maximum cpu speed to highest or adaptive in power manager, this noise comes out, when it set to low or lowest where no changes of cpu speed (cpu runs at lowest speed), the noise is completely gone.
it's not noticeable unless im in a very quiet surroundings such as library or night at home. it drives me crazy for once.
does anyone else have this issue?
im wondering if i need to send this one back for replacement. if everyone has this issue, then it's a issue with specific CPU
btw I have following configuration
i5 560M 2.66G
BIOS: 1.34 (yes it's 1.34, official website only has 1.33..........im not sure why i have 1.34)
Built in video card

welcome to the lenovo family of "issues" ! If there is any way to either get your money back and buy another T410s without whining or change it to another model do it now

well, that's why i asked question here, because it's happening everyone's T410s then it means a CPU desgin flaw, and i rather not to send it back and replace another one, because that takes for years to get it back..............
if everyone elese's has no little high frequency noise when CPU runs under HIGHTEST performance, then i will have to send it back.

Hi. I bought a T510 several months ago and had the same problem with cpu noise. I sent it to the repair depot 5 times and they replaced several parts, but not the processor. The last time it went for repair, it was kept 6 weeks, and finally it was decided by customer service to replace the entire machine. I opted for a T410s this time, and it seems to have the same problem. I'm curious how your situation was resolved.

gday, i have just bought the same model.
my bios is up to date (1.41) .
i have the same noise, as soon as the machine runs on battery.
did you find a descent solution to this problem?
did you get your notebook replaced?

Hi there. I have this problem. Have had the computer for 8 months, had everything replaced in the computer and what I am told is that there is nothing they can do.
Can I return the computer and get a different model?
Help me out guys.
