I was given a very old Acer inspirion laptop, windows 7 Vista and I reset it to factory settings when I first got it and that was almost a year ago and now it's so full, out of date and giving me problems I need to do it again but it keeps saying I don't know the current password. Now I can't do anything without it asking for the password. Even tapping F2, F12, and the alt/F10.
FAQ & Answers
Retry the Alt+F10 coldboot recovery method ***exactly*** as shown in this video

Just to be clear (1) Is this an ACER 7720Z or a DELL Inspiron? (2) Is its operating system Windows 7 or Windows Vista? Jack E/NJ
The safest method to remove a BIOS password is to try to drain, short or remove the BIOS chip's coin battery on the mainboard.
We'll try draining first. Remove the charger & main battery. Then press & hold the power button for about a minute. Then press & immediately release the power button a half dozen or so times. We're trying to drain all charge on the BIOS chip so that it goes into a default state.
Reinsert the charger and battery. Press the power button once to see if the BIOS password has been removed.
OK. The 2nd easiest method is to see if the memory module compartment on the mainboard has any BIOS re-set jumper pins. If so equipped, they'd be located somewhere around the periphery of the memory modules so they wouldn't have to be removed to access the pins. Jack E/NJ
Remove 4 or 5 screws holding a rather large irregularly shaped panel with ventilation slots on the bottom of the laptop. Jack E/NJ
