Samsung r480 jumper location

Sounds like a GE with a motherboard failure. It would help me if you could provide a model number in the locations addressed in the photo below. Cam you locate the model number? Control board or adaptive defrost control board is common on regrigerator that has had a power failure but not having nthe model number not being in your post makes it hard to tell you which to look for, Thanks Sea Breeze

The location of the jumpers or dipswitches may vary; however, here are some locations of the jumpers / dipswitches.

1. On the edge of the motherboard - Most jumpers are located on the side of the motherboard for easy accessibility, verify by looking at all visible edges of the motherboard.
2. By the CMOS battery - Some manufactures will place the jumper to clear the CMOS / BIOS password by the actual CMOS battery.
3. By the processor - Some manufactures will place the jumpers by the processor of the computer. However, note that in some cases these jumpers will be to change the processor and not the password.
4. Under the keyboard or bottom of laptop - If you are working on a laptop computer the location of the dipswitch (almost never a jumper) can be under the keyboard or on the bottom of the laptop in a compartment such as the memory compartment.
5. Other visible location - While it is possible that the jumpers / dipswitches may not be in a visible location, most manufactures try to make things easier by placing the jumpers / dipswitches in another visible location.
6. Jumpers may also be found underneath or allongside the memory modules.

I hope this helps but suggest that the manufacturers web site or your instruction manual, may have the answer.

Motherboard Jumpers:
Some, but not all, motherboard manufacturers provide a set of three jumpers on their motherboards that provide you with the ability to clear the Bios/CMOS settings, thereby allowing them to be reset. For the most part this is used when the Bios/CMOS data becomes scrambled and you need to clear the Bios/CMOS in order to return the computer to a functional state. This same procedure, however, can be used to clear passwords from the Bios/CMOS setup. Typically a jumper will be found across pins #1 and #2 as the default position, and by shutting the computer down, unplugging the power cord and then moving the jumper so that it is across pins #2 and #3 will clear the Bios/CMOS settings.
Here's an example of a Supermicro PIIISEA motherboard.
As you can see from the picture, we have added two small red arrows. The arrow to the left denotes the location of the "Clear CMOS" jumpers, while the red arrow to the right denotes the location of the CMOS battery.
Here are the procedures if the jumpers are present on the motherboard:

• Locate, if possible, the instruction booklet for your motherboard. If you cannot locate the booklet, then user the motherboard references on this site to locate the manufacturer and see if a manual is available there. You may also want to closely examine the motherboard itself.
  
• Shut down your computer and disconnect the power plug.
  
• Now identify where the jumpers are located, then check the present pin location and the location of the jumper on those pins to determine their default location. As an example, the default location on the above motherboard is to have the jumper across pins #1 and #2. Write it down!
  
• Next, move the jumpers from the their default location (Example: from across pins #1 and #2 as above) and then place the jumper across pins #2 and #3.
  
• Leave the jumper in place for 20 to 30 seconds and then return it to its default location.
  
• Now plug the power cord back in and restart the computer.
  
• When the computer begins it's startup (boot) process, tap the DEL, F10 or F1 key, (whichever is appropriate for your computer) to get into the Bios/CMOS setup. If you need more detailed information as to how to get to the Bios/CMOS setup, follow this link. Bios Basics
  
• Once into the Bios/CMOS setup, look for a section or area to set the Bios/CMOS to its default settings. This will return the motherboard to either its basic or optimum settings depending upon the motherboard manufacturers settings. You will then need to verify certain settings, such a CPU and memory as well as hard drive type and size recognition. If you need more information regarding these settings, follow either of these links: For an AMI Bios or for an Award Bios.
  
• After making any final adjustments, save your settings and restart the computer. The Bios password should be gone and the Bios set to its optimum settings.

If the "Clear CMOS" jumpers are not present or not available:
The procedures for clearing a Bios/CMOS without jumpers is essentially the same as those given above when they are present, it just takes a little more effort.

• Shut down the computer and disconnect the power plug.
  
• Locate, if possible, the instruction booklet for your motherboard. If you cannot locate the booklet, then use the motherboard references on this site to locate the manufacturer and see if a manual is available there. You may also want to closely examine the motherboard itself.
  
• Now identify where the battery is located on the motherboard. It will be approximately 1/2 inch in diameter.
  
• Normally these batteries are held into place with one or more small clips over the face of the battery. Carefully lift the battery out of its socket and set it aside. Note: Some batteries are actually soldered to the motherboard, so take that into consideration and be careful.
  
• Leave the battery our of the computer for about 20 to 30 minutes and then return it to its socket.
  
• Now plug the power cord back in and restart the computer.
  
• When the computer begins it's startup (boot) process, tap the DEL, F10 or F1 key, (whichever is appropriate for your computer) to get into the Bios/CMOS setup. If you need more detailed information as to how to get to the Bios/CMOS setup, follow this link. Bios Basics
  

There are two ways to reset the boot or the bios password:

1.By removing the CMOS battery

You have to shut down the computer , disconnect the power plug and open up the unit and locate the CMOS battery ( which usually looks like a coin) . Carefully lift the battery out of its socket and set it aside.Leave the battery our of the computer for about 20 to 30 minutes and then return it to its socket. Now plug the power cord back in and restart the computer.
It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.

2. By using the motherboard jumper


Shut down your computer and disconnect the power plug. Identify where the jumpers are located. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc. Then check the present pin location and the location of the jumper on those pins to determine their default location. As an example, the default location on the above motherboard is to have the jumper across pins #1 and #2. Write it down! Next, move the jumpers from the their default location (Example: from across pins #1 and #2 as above) and then place the jumper across pins #2 and #3.Leave the jumper in place for 20 to 30 seconds and then return it to its default location.Now plug the power cord back in and restart the computer.Next, move the jumpers from the their default location (Example: from across pins #1 and #2 as above) and then place the jumper across pins #2 and #3.Leave the jumper in place for 20 to 30 seconds and then return it to its default location.Now plug the power cord back in and restart the computer.
It'll reset all BIOS settings as well as the password and you'll need to re-enter all settings.

You can reset bios password with 2 method.
(1) open cpu cabinet cover then find motherboard .Pull cmos cell from motherboard for 15 minutes then again put it in it's position .then it not ask for password.
(2)You can clear password with jumper settings find jumper on motherboard named clear cmos it has 3 pin .1-2-3
Put jumper in 2-3 position then again put it in 1-2 position then check .
Let me know if you need more assistance.
Thanks for using FixYa.

A. By Using the Motherboard Jumper:
In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.
Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.
When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.
Make sure to turn the PC off before opening the cabinet and resetting the jumper.

B. By Using Software:

I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Hi,

This will be found right near the CMOS battery

Locate the 3-pin CMOS jumper (RTCRST) on the system board.
Remove the jumper plug from pins 2 and 3.
Place the jumper plug on pins 1 and 2 and wait approximately five seconds.
Replace the jumper plug on pins 2 and 3.

try to locate if theres a jumper setting that says 'jbat' move it to 2-3 sttings for a while then back again to 1-2.

turn off the power and briefly press the power switch to discharge electricity. open up the case and locate the clear cmos jumper (check the manual for the exact location) move the jumper from pins 1 -2 to pins 2 - 3 for about 10mins. return the jumper to pins 1 - 2 and close up the case. and turn on the power supply and try to reboot again.

try to reset the BIOS to default either take the M/board battery out for at least 1 hour reinsert battery and try or
On M/board will be writing with reset bios or similar usually a small 2 pin connector with a jumper on 1 pin connect jumper over both pins remove jumper refit over 1 pin and reboot
If 3 pin setup remove jumper and fit over middle pin and the one it was not on replace back to how it was and boot computer
