Hi,
I finally succeeded today Errors or to find the cause, which in my Thinkpad T60p VEF2007 caused the squeaking. The decisive information I found in http://www.thinkpad-forum.de . The reason for the noise seems to be the permanent change of the C-states of C3 to C4 to be. Guilt is the USB1.1 module, this prevents the CPU because in the C4 state to switch permanently. Remove the module "uhci_hcd" means
"rmmod uhci_hcd
" then the problem should be history.
with me I can reproduce again and again, so it must be here to it.
As for the battery life. I have the laptop now since already in December annoyed me in 2006 and have all the time that the battery life 9-cell battery included only moderate 3-3.5Hrs. holds. The consumption also means overclocking the ATI I came down just 28-26Watt consumption. This is well on German real shit ....
With various options without lowering the core voltage , I succeeded to the consumption of 12.6 watts proud! . Zusenken I have not gotten the full load Battery .. But with a charge of around 80% promised Powertop a period of approximately 5.5 hours ^ ^ Thus, it can achieve a total period of hopefully more than 6 hours.
The screenshot was taken with about 40% battery.
I am not yet have discovered how can I reduce the high number of wakeups from ACPI on.
The best that is in office work and starts chatting and surfing the fan using TP-Basic only every 20 minutes for about 10 seconds. Or if you leave your laptop short and does not enter it even reduced the temperature of itself and thus remains with the GPU (for me the highest temp) 58-61 degrees.
room temperature about 23 degrees.
Here is the command that are necessary to achieve the capacity .. This should be done when using battery power ..
# / bin / bash # By default this
script does nothing.
# Trackpoint sensitive (recommended for trackpoint experts)
echo-n 200> / sys/devices/platform/i8042/serio1/sensitivity

# Bluetooth down

0 exit
just this case, still be adapted to individual needs.
real nice:))
That may still experience the ... one man man ..
Have a nice Day
