By resetting the CMOS battery.
Solution: Carefully unscrew the whole back cover of your laptopAspire 5750z-4882 and locate the small battery. If the battery can be removed manually, slowly pry it out and try putting it on again after 5 minutes to reset the BIOS into factory settings.
B. By installing a CMOS resetter software. This powerful tool helps users to reset the CMOS password without opening their laptop. This method saves more time and it is more efficient to use. A good example is the CMOS De-animator v 2.1 software. Take note that CMOS passsword resetter softwares may or may not reset your bios o it may also further damage your laptop. Try reading all the warnings first and the manual before using.
C. If all else fail, you may want to reconsider contacting the customer support of your laptop from their official customer support page or going into their local service service center available in your area.
