# ACPI driver problems within Lenovo X61

Hi guys,

Maybe someone can tell me witch direction I have to go to find a solution to my problem. Inside my fedora 19 install exists an conflict that I can't solve, and affects to my system as a slowdown in boot, and in battery handling. This bug was reported in bugzilla since F18 has received the (if I remember well - cca.) kernel 3.6.8 - yet I have no answer/feedback yet, but maybe someone knows this, and maybe a replacement for my driver issue. I'm also sure that is not HW problem, because under earlier kernels seems no such problem. So, here is what happens: Sometimes the bat0 indicator goes crazy, if I have to unplug my laptop. I'm pretty scared, because the battery isn't cheap here, and simply nerves me out, when unplugging results different battery levels, and shutdowns - charging. BTW - BAT0 is almost new, just 3 months old. The indicator drops down from 100% to 15-30%, and for charging back says days (!). Maybe this conflict causing this, and possibly not only for me. In dmesg the following can be seen:

[   37.918807] ACPI Warning: 0x0000000000001028-0x000000000000102f SystemIO conflicts with Region \_SB_.PCI0.LPC_.PMIO 1 (20130328/utaddress-251)

[   37.918829] lpc_ich: Resource conflict(s) found affecting gpio_ich


So my question is from where can I have the proper ACPI driver, and how can I fix this?

Thanks,

Zoltan

Well, possibly solves several battery usage problems, yet, the driver issue is still there. :(
