Jbat1: How do I short a JBAT1 to reset my CMOS? : buildapc

Con los pines 1 y 2 mantienes la configuración actual de la Bios, con los 2 y 3 reseteas la Bios a los valores de fábrica pero ello no te va a dejar ver los menús que tu quieres, que es probable que estén metidos, pero estarán protegidos de alguna manera. Las Bios de Gigabyte tienen algo similar en que ciertos menús sólo se desbloquean pulsando a la vez Ctrl+F1.

Fix BIOS Black Screen Problem in 2 minutes

2 minute read

Due to some misconfiguration in BIOS settings or after BIOS update, we may face BIOS Black Screen Problem in our computer. When this problem occurs no displays are shown on monitors. Here we talk How to Fix BIOS Black Screen Problem.

Why BIOS Black Screen Problem

When we change the Motherboard BIOS settings we may face this problem. Basically, if we change overclock settings of the RAM & processor which are not compatible with the hardware then BIOS Black Screen Problem will occur. If we enable BIOS default auto fallback on boot problem then if BIOS Black Screen Problem occurs, Motherboard will automatically change its settings to factory default setting. But most motherboard manufacturers make this auto fallback setting disabled by default.

Another time when we flash the BIOS or update the BIOS then we may encounter BIOS Black Screen Problem. Basically, after flashing the latest BIOS, it tries to restore old settings which sometimes become incompatible. Then we face no display on our computer screen.

How to Fix BIOS Black Screen Problem

There are two ways to solve the issue. Either go to service center or try to Hard Reset BIOS CMOS by yourself. Hard reset using Motherboard Jumper is little bit tricky. But I promise if you follow me, any non technical person also can do this.

Hard Reset BIOS using Jumper

Almost every latest series of desktop motherboards does have a pair of jumper pins named “JBAT1”. Here in the above photo, we can see the JBAT1 Jumper pins near the Battery & NVME SSD slots. Here the motherboard used model name is MSI B450M Pro VDH-MAX.

Using any pin or screw driver top just short those two jumper pins for 10 seconds. Then switch on computer & you will see BIOS will loads up with factory default settings. Remember do not try to do this when the computer is on or power in given to the motherboard. Do this after unplugging power sockets from the electric board.

Still no Display?

If you can’t find the JBAT1 pins on your board after doing the above method still BIOS Black Screen Problem persists, I must recommend you to visit the nearest service center without any further experiments. It may void the warranty for any physical damage or short circuits.

If after pressing the power button to turn on the computer, if the computer’s fans and LEDs start to work normally, but there is no display on the monitor, use the following troubleshooting steps to troubleshoot.

• Check compatibility with

processor

• Check processor power cable connection
• Perform a POST test
• Reset BIOS
• Check indicator EZ Debug

Check processor compatibility

To check the compatibility of the processor with the motherboard, go to the MSI official website, open the search field by clicking the corresponding icon in the upper right corner.

Enter the motherboard model name and press the Enter key.

Click the Compatibility link below the model name.

A list of compatible processor models can be found on the CPU tab.

If your processor is not listed, it does not meet MSI’s recommendations. For the best performance from your computer, you should use compatible processor models.

Check processor power cable connection

If you are using a compatible processor, make sure that the processor power cable is properly connected to the motherboard.

POST

Leave only the motherboard with the processor and processor cooling system, and one memory module in the computer.

Disable all peripherals such as USB sticks, hard drives, PCIe adapters.

Try to boot your computer. If it works fine, the problem is obviously with one of the peripherals. Add them to the system one at a time until you determine which one is causing the problem.

If the problem still persists, proceed with the diagnosis as described below.

Reset BIOS settings

Power off the computer. To do this, turn off its power supply using the appropriate button, or simply unplug the power cord from the electrical outlet.

Clear the BIOS settings by moving the JBAT1 jumper from its original position 1-2 to position 2-3.

Alternatively, remove the CMOS battery from the motherboard, wait 5 minutes, and then install it again.

Check the EZ Debug LED

The EZ Debug LED is located next to the 24-pin ATX power connector. It reflects the status of key components as the computer boots up. When a problem occurs, the corresponding LED lights up.

Processor light on: Reinstall the processor, check that the processor itself and its socket are not damaged.

Memory light on: Memory or processor not detected, not working properly, or incompatible with motherboard.

Video card LED on: The video card (or processor with integrated graphics core) is not detected or is not working properly.

Boot light on: No boot device detected or not working properly.

If the problem persists, try testing the monitor, video card, and video cable with another computer.
