    Each Dell Inspiron has a master password which will clear the BIOS password. You can get this number by calling Dell Technical Support at (800)624-9896.

    Dell Technical Support will request the Service Tag and Express Service Code from the bottom of your Inspiron.

    If you were not the original owner of the Inspiron, Dell will transfer registration of the used Inspiron from the original owner with only the Service Tag and Express Service Code from the tag on the laptop.

    To transfer the registration of a used Dell Inspiron, fill out the Transfer of Ownership form on Dell's web site.

    Dell Latitude BIOS Password Recovery
    Christophe Grenier has written a program that will calculate the master BIOS password for Dell Latitudes from the Service Tag number. That program is available at http://www.users.globalnet.co.uk/~skynet....

How to remove a bios password from hp 6720s


Why can't people put a problem in the right catagory?
Generally, you can remove the Bios backup battery or use the jumper on the motherboard to reset the bios completely.
Google "reset bios" to get an idea of how to do it, or do the same in Youtube for a video. Lots of them are out there.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572
Manual
. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

Hide file folder WITH A password


For the most part you need 3rd party software, or a USB drive with security built in. Just remember you are at the mercy of those companies if you lose the password. Plus some software will only works locally. For instance if someone removes the drive and connects it to another computer the files are wide open.
Win 7 Ult and Ent (high end editions have Bitlocker built in.
A simple way is to create a folder within his login account docs and choose hidden as the properties. The only way to see it would be to change folder properties and make hidden files visible. This is just cloaking, because anybody with admin rights can see them.

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
