I have an acer aspire 5100 laptop and I want to change or remove bios password
The laptop password cannot be reset by removing the battery and there is no jumper for the CMOS or bios reset. You must go to Acer to obtain the master password as laptop computers have NVRAM (non-volatile RAM) that retains the password forever as an anti-theft protection. Steve Medley

for removing bios password you must have to remove cimos bettery for few mnuts but for doing this you have to open case of laptop
and it is not adviceable because your notebook is new one
so find any service station if yor laptop is in warranty period or you may lose your warranty
there isn't any other way to clear cmos without opening case of your laptop and remove cmos bettery
unless you will get cmos password but as u said you didn't put password in your laptop it might be possible that your notebook manufacture him self had put any password in cmose as a company policy
in that case also you must have to go to them
