The latest annoyance: if I stay in the GRUB boot menu for too long my notebook overheats and then shuts down to try to avoid damages.
It happens ONLY in GRUB and only if I go from GRUB to a textonly tool (eg. memtest86).
In every other case such as staying at the POST screen, entering BIOS, selecting the boot device, booting Linux or XP, whatever is malfunctioning at the GRUB boot menu gets initialised properly and the problem does not show up.
I love FOSS so much, you can also choose how to kill your hardware.
