Hi Acer Community,
the problem is: I can´t enter BIOS on my notebook, I don´t know what´s the problem and I have now idea what to do now.
What did I do?
I had Windows 7 installed and everything worked well. Then I decided to install Debian GNU/Linux instead. That worked as well, though I had some issues with wifi connection and the system did not shutdown properly. That´s why I wanted to reinstall Windows. In order to boot from DVD, i had to change the boot order, because Debian always changes its own boot priority to max - so at this point BIOS was still working! During Windows 7 setup, I formated all HDD partitions, created new ones and BAM! Windows 7 would not installt because it has some problems with GPT partitions, it said it could not install to this partition (I tried all). So I canceled the installation and restartet the system. Of course now it printed "Operating system not found". I could not even enter BIOS (allthough it showed the normal message "Press F2 ..." and the Windows 7 installation had trouble finding some drivers, so it did not even start correctly. The Acer Recovery I created from Windows 7 (before installing Debian) started, but it failed to copy the first file and ended. So nothing worked. However, I could install Debian again, which is now my OS.
Current situation:
OS is Debian 7, it´s working, but I have many problems with it (cannot change display brightness, often looses wifi connection, instantly reboots (!) after shutdown)
Can´t enter BIOS: I have tried F2, DEL, ESC, F10, F12 without success.
Debian is again at boot priority #1, and I can´t change it without BIOS (so not able to BOOT from DVD etc)
I have tried to short the G2201 contact (service manual describes how to use it to remove BIOS password), no success.
Maybe it´s import that I use GRUB bootloader, which was automatically installed with Debian
So at this point, I can just hope that someone of you has an idea what to try next.
Thank you for reading this
