my DeLL Inspiron laptop time to time freezes(as usually when I need it most-such as saving opened doc etc.), presumably when acpi turns on cpu cooler, at list those events frequently coincide. dmesg after reboot is given below followed by lspci
Unfortunately during freezing event, kbrd, touchpad don’t work, even ctrlF[3,4…] cause no reaction.
Any help/comments are greatly appreciated
