electric surge did something to the notebook. After several days of trying F10 and repair

we finally got to do the recovery and first try it errored second try seem to make it threw well did a scndsk and seem to stop on 4 of 5 parts stating on part 4 fixed somethinig after several hours I thought the system was frozen so shut it down. Now when we try to boot it ask for a password. We can do F2 and get in bios but they are set to supervisor and have no idea why or how that happen I did not set any password except when booting up the notebook to the desktop. Any ideas is there anything we can do to bypass the password or do we need to send this back to Acer? thank you for any assistants

I have open a thread for you Doreen acer aspire 4315 wont boot up
