Are CMOS batteries universal?

Yes, you can install any 3V lithium battery from other motherboards. I think all motherboards use the same voltage (3V).

Can a CMOS battery cause a black screen?

Can a CMOS battery cause a black screen?short answer Yes. Because the CMOS battery is dead, the BIOS will lose its settings, so a blank screen will most likely appear. If it’s a CMOS battery, change it and load the optimized defaults in the BIOS and see how it goes.

Is there no jumper to clear the CMOS?

If there is no CLR_CMOS jumper or [CMOS_SW] button on the motherboard, follow these steps to clear the CMOS: Gently remove the battery and leave it for about 10 minutes or more. (Or you can use a metal object to connect the two pins of the battery holder to short them out.)

Can the CMOS battery be replaced when the computer is turned on?

If you remove and replace the CMOS battery with power on, you can Lay the PC on its side Or put some tape (or both) on the old battery and the new battery first. If you do, the tape will allow you to grab the battery when you pop the old battery out and also keep it from falling onto the board.
