Question about Samsung Np200a5b-a03us Notebook
Resetting the bios in most laptops requires you to disassemble the unit.
For many of the samsung laptops you will need to power off the device, unplug it from the charger. (Leave battery plugged in)
Close the lid of the laptop and flip it over so it is resting on the back of the lcd screen.
On the bottom of the device there should be a small panel held in by a single screw. Unscrew this and set the plastic panel aside.
You should now see the wireless min-pci card. This is also held in place by 1 or 2 screws. Both antennas also connect to this card, The antenna connectors are fragile and may be damaged if handled roughly. Carefully lift the antenna connector from the wireless card.
remove the screw(s) holding the wireless card in place. Set the wireless card aside.
Under the wireless card you will see some metal pads on the motherboard, next to them it should read "RST" .
Short these two pads using tweezers or other metal object (DO NOT SHORT ANYTHING ELSE OR YOU MAY DAMAGE YOUR ENTIRE LAPTOP) the shorting process should be done for roughly 2-5 seconds.
The BIOS is now reset, any settings or passwords will be removed.
Reassemble the laptop being very careful with the wifi antenna connectors, they simply push on, but need to be positioned in the correct way before being pushed down. Tweezers may help greatly in this portion.
Once back together, flip back over and plug in charger.
If you do not see the "RST" lettering on your model, please contact samsung support or a certified repair shop to perform the reset for you.
