How to Fix Black Screen After BIOS Update

Let’s say you wanted some changes in your BIOS for gaming, rendering, or working something vital to you. As the motherboard or computer manufacturer has the update on the website, you updated your BIOS this way.

But, this is risky because it is seen that sometimes after updating BIOS, when people restart their computer, they find a black screen pops up. So, if this happens to you too, follow the instructions and solve your problem.

Here are the steps to fix a black screen after Bios update:

1. Check the Reset Button

Force your PC to shut down. Unplug all the chords and peripheral devices. I don’t know which motherboard you use. Some motherboards contain a reset button, and some don’t.

So, if your one contains a reset button, press it, and you’re done. Power up your PC and see if it solves your problem.

2. Remove Memory Battery

if your motherboard doesn’t contain a reset button like mine, you must rely on the CMOS battery. Replacing it bring back the screen again for some people.

So, if you are using a desktop, then follow this:

  • Remove all the screws on the backside by using workable Screwdrivers. 
  • Slide the side panel off. 
  • Track down the motherboard. It is a shiny, round metal, bigger than a watch battery. 
  • Remove the battery from the motherboard. Wait for 5-10 minutes. 
  • Replace the battery with a new one in the same place with the same orientation.
  • Power up your PC.

But if you are a laptop user, you have to:

  • Flip your laptop over and remove the screws one by one. 
  • Track down the motherboard and remove the shiny and round CMOS battery from the motherboard. Generally, it is placed within a small holding socket. 
  • Insert a new battery in the exact location with the same orientation. 
  • Rescrew every casing in the laptop and reinstall the battery. 
  • Reconnect AC power and turn on your laptop.

If this process solves your problem, you don’t need to follow the third one. But if it doesn’t, don’t hesitate to follow the third fixation.

Caution: Before starting to pull out the CMOS battery, make a note of all BIOS settings on your system.

3. Short CMOS Jumper

After powering off the PC, unplugging the power cord, and removing the screw, find the CMOS battery. 

  • Use a jumper cap to short the CMOS pins. You can use any screwdriver or conductive material as a jumper cap.
  • Press and hold the jumper cap for 10 seconds, and then remove it.
  • Plug the power cord and power it up. See if the problem resolves. 

As almost every laptop does not have a jumper, you can’t perform this operation on your laptop.

You might be wondering about jumpers right now if you don’t know what it is and what the work of a jumper is.

So, what do Jumpers do?

Jumpers enable the computer to close an electric circuit, allowing the electricity to flow on another circuit. It is situated on the motherboard of a PC and configures computer peripherals, say, HDD, sound cards, motherboard, etc. It consists of small pins that are covered with a small plastic box.

In your A levels, you might be familiar with the shunt. Well, these jumpers work like shunts, or you can consider it as a shunt. Even it is also called jumper shunt sometimes. 

So, here are all the three solutions that have been stated. Follow this, and I believe you will be able to fix your problem.
