`dmidecode -s bios-version` doesn't match the BIOS_VERSION variable in the script (so change according to your bios)

Extrating the DIDL/CADL Offsets:
Extracting the DIDL/CADL Offsets:

1. dump the bios with acpidump to file
2. extract dsdt tables with acpixtract <file>
this should create some files, one beeing something like dsdt.dsl (the file with .dsl is the important file)

How to execute:
* chmod +x fixbacklight.sh
* sudo ./fixbacklight.sh <start | shutdown>
* optionally copy to /usr/local/share and let it execute by /etc/rc.local
* on shutdown ./fixbacklight.sh shutdown (since it apprently causes some strange bug - sometimes the harddrive doesn't get detected on the next softreboot - idfk why). - add it to /etc/rc.shutdown
