Hi, Recently, I bought a new laptop (dell D420) and now, I'm discovering the tool and I need a bit help to understand what I can do with thoose informations.
By killing gnome-power-manager, un-blinking the cursor in gnome-terminal, saving power with ipw3945, patching dhcpcd and compiling my own kernel, I saved roughly an hour (Now, I've 6,5 hours). But I think I can do better :-) Can someone explain me a bit if ipw3945 interrupts are normal (I was not using wireless), what can I do with modprobe (or if it is normal) and what the message with pcscd can help me to improve pcscd. (Pcscd is a soft for smartcard reader) Thanks a lot for your help, Antoine C.
