hello,
i have recently update the bios of my laptop acer aspire ES1-511 from 1.03 to 1.10 and now i have a lots of problem: my keyboard doesn't work anymore, sometimes the touchpad too, and i can't turn on my computer if the power cord isn't plugged in.
i thougth i could reset the BIOS but when i go in the BIOS screen the keyboard doesn't work, so i can't press f9 for the reset. what i have to do? i've open the laptop but i haven't find the CMOS battery or the jumper for the BIOS reset.
please help me to fix it.

    you can use an external USB keyboard to try to load defaults.

    the CMOS battery is near the ram slots but it's soldered.

    So how i could remove it? Or there is an other way to reset it? I try to install an old version of the BIOS but the program block the installation, i've uncheck the fleg of [check_BIOS_version] but now the installer say that he can't find the BIOS that i want to install.
