X61t (new) with whining noise

2008-09-18, 0:48 AM

hi, I have this problem on battery mode.... It's really really annoying me. I heard it's caused by the C4 state of the CPU but I don't know if it is true.

I still have warranty but I'm in school right now, so I don't think I can afford the down time in sending in my unit or something.


Please help.

Since you need the machine every now and then, i would suggest you try to Submit Request to Lenovo right here and you would need to register as Electronic Service Call member for able to be called back for the problems you submit.


Try that ;)

I noticed that the among the changes to the most recent BIOS firmware is a fix that apparently helps with whining noises.  If you haven't flashed with the latest version, perhaps it will help.
