#Step 4

If your BIOS does not have an option to return to factory settings, things are more difficult. Because the BIOS is stored in ROM, it must have a constant power supply to store any changes you make to it, otherwise it would reset every time you disconnected your laptop from AC power. Removing power to the BIOS resets it to factory settings and involves disconnecting a small battery attached to the motherboard. On many laptops, the BIOS battery is easily accessible through a door on the bottom of the unit. Unplug the computer, remove the main battery and touch something metal to ground yourself.

Step 5

Remove any screws holding the BIOS battery door in place. Then identify the battery, (it is generally a small lithium "watch" battery), and remove it taking care not to damage any surrounding circuitry. Let the computer rest for a minute or two to discharge any remaining power, and replace the battery.

Step 6

If your laptop does not have an easily accessible door for the BIOS battery, you may have to dive deeper and disassemble the computer to find it. Consult your laptop manufacturer's website for information on replacing or removing the BIOS battery from your model.

1)Remove Laptop Battery
2)Take off Memory Cover(underneath - square cover, Sits
in middle of laptop 1 retaining screw
3)Using two thumbs spread spring clips to outside and
pull out RAM memory.
4)Remove clear vinyl label opposite RAM memory slots in
upper left corner( laptop battery slot is on right, DVD
drive is facing away from you)
5)Using a magnifying glass (unless you have perfect
vision)in the upper left corner you will see JOPEN1 with
a white silkscreen square next to it . Inside the square
you will see what looks like the letter T over a U.
Using a metal paper clip short the U to the Silver 1/4"
post connecting the motherboard to the laptop case(this
is you ground, it is located above what looks like a
silkscreen outline of a chip)hold for 25 -30 seconds.
6) Place back your RAM memory, put in the laptop battery
and test start laptop. you should see a selection of F1
or F2 for setup. Using the F2 gets you into the Bios
menu where you reset the time and date. Then Tab over to
the SECURITY setting tab and change your passwords. Now
hit F10 key ,yes to save and your done!
Note: if your having trouble your most likely grounding
the ground(that blob of solder about 1/8"dia on both
ends of the "silkscreen chip outline" This is about as simple as i can break it down
