    Hello!
    I tried to reinstall win8 to win7. After setting in the bios the possibility of booting other media, i.e. turning off these locks, after rebooting, the laptop turns on, the Samsung logo appears with a bar at the bottom F2 BIOS F4 BOOT something there and after 2 seconds there is a restart with such a characteristic tick. Everything loops and the same thing happens.

    Bios restart (30 minutes without battery) did not help.

    Somewhere I found that the switch may be broken, but replacing it did not help. I have no ideas what to do because the warranty has already expired and I would like to try to fix it myself.

    For reprogramming the BIOS chip in an external programmer.

    It worked properly on the previous system?

    On Windows8 it worked without any problems. It's just that this system is still there because I haven't had time to install anything yet.

    Yes. It also restarts without the disk.

    I just wrote that I was doing a BIOS reset by removing the battery for 30 minutes. Unless there is some other way to do it?

    I understand that I will not do it at home and I have to go to a service? I read that you need a programmer that is not cheap :)

    You need a programmer, adapter, batch and soldering skills.
