Nice how to Mike. Another Tip: All of my motherboards have the 2-pin plastic shunt or jumper on them...but I only have them on one of the pins, so if I do need to reset the CMOS...the shunt or jumper is already there. I remove the battery, put the shunt or jumper on both pins for about 30 seconds. Then I put it back on one of the pins again. Put the CMOS battery back in. Hope that helps. Thanks for sharing Mike and Lady Kath. Cheers

[@mikesunboxing]

yeah those plastic jumpers used to be everywhere!

@@mikesunboxing I used to work in the electronic industry so I always had them lying around. I'm sure Amazon sells them cheap. Wouldn't hurt to have some on hand. Cheers

Great PSA video Mike, thanks for sharing 🙂

Thanks for watching! These are always handy for reference

Great reminder tutorial! I upgraded to B550 a few weeks back and in error put the MSI bios into overclock mode. Had to think what you had previously instructed. Power off, pressed the power button for 10secs, then used my MUB screwdriver to short the pins. Restarted and bios back to original settings! Phew! Thanks Mike and Kath for all you do 🐈👍

[@mikesunboxing]

Glad it helped! The MUB screwdriver that is 😎

I never forget to leave a like. there is always something to learn from MUB videos 😀

Hi, Mike. Good video. Because I used to contently tweak my RAM sittings, I've probably cleared the BIOS at least five-thousand times. Never once have I ever removed the battery. But there's no harm in being thorough. One tip I have if your motherboard doesn't have a Clear BIOS button, is that you can connect the reset button on the front of the case to the clear BIOS pins. That way you will have a button on your case and won't have to mess around with a screwdriver. But if you're using the reset button for changing RGB or something, you can buy a reset button for cheap and attach it someone on your case that's easy to get to. I hope someone finds this little tip helpful.

your right but tbh iv had to clear several times with batterys especially on my Favorite Mo Bo ASUS Strix mine needed a Bios reset twice out the box Looool more from my install mistakes but still it wasn't posting and bios reset wasn't wrking the battery returned to like out the box then i got no post again so i must have repeated the same mistake or had a error along the way Battery out several times its Why im scared of my Bios now hahah

[@PapaMav]

Good tip Big O.

[@PapaMav]

For my test bench MOBO, I wired up a push button momentary switch, soldering two wires from some old header that I cut up so it now just has 2 pins, to the legs on the switch and this is what I use for my "power button" on the bench.

[@PapaMav]

Thank you for the refresher Mike.

Getting hard to find new content but an updated video will always be helpful

[@zedzino11]

Funny how 2 months back I needed a updated video but I watched your old one instead😂😂😂😂😂😂. Tbh I need to rebuild my pc so this improvement video is so helpful. Thanks👊🏼

Thanks for watching

Mike loves a bit of firmware around his cmos!

[@skullphish]

Hi Mike, Love your content, especially the motherboard deep dives! Would be able to review the "Phantom Spirit 120 EVO" cpu cooler by any chance? there's plenty of coverage for the "phantom spirit" but nothing on the EVO.

[@mikesunboxing]

I'll check it out, but at the moment the price is still a bit steep for what it is. You can get 360 aio coolers for less

[@Ladioz]

This is a great video for people to reset their bios if there are issues. Am I wrong to say that motherboard manufactures need to implement a factory reset Bios within the Bios itself? Resetting everything to default isnt cutting it for me... all we want is a simple button setting

[@OlettaLiano]

Most motherboards allow you to save your current working BIOS settings. So if you mess things up when making changes to your BIOS, you can clear it, and then reload the working version. Thus not having to reset everything from scratch all over again.

[@mikesunboxing]

There is a setting in the bios if you can still access it that will load optimised factory settings

[@OlettaLiano]

@@mikesunboxing True, and it's always a good place to start.

[@REALLYRANDOMREVIEW5]

I have had to do this many a time works a treat ! did this feature get invented ? like by users or was it factory standard i always thought the battery was to not lose time and dated in older systems and us modders found a glitch i didnt know thats an actual protcol the more you know hey thanks for the Info as Always Mike and Kath hope you new year started well

[@mikesunboxing]

think it has been an option for a long time. even in the old 286 days

[@RoteAugen66]

I accidently cleared the cmos with the psu switch on;however, the computer hasn't had problems so far. But, could it have problems in the future?

[@mikesunboxing]

No that should be fine, usually the residual current in the psu would prevent a reset so it would seem yours was a bit of good fortune

[@kokobil]

So to clear Cmos you need to BOTH remove battery AND do the thing with the screwdriver over the clearcmos pins? Isn't just enough to remove battery and wait 5 minutes?

[@mikesunboxing]

no because a lot of PSUs have massive capacitors and keep the 5v standby rail active for ages

Hi, some assistance, my desktop computer dell model, it's demanding repair if I power it on what could be the way to troubleshoot this?. Thanks

Just a litle tip. Whilst you do have the battery out, do make a voltage measure of it. You be suprised how many batteries (even new one) don't hold specified voltage. btw voltage should be 3V

[@mikesunboxing]

good idea, will add that into the video for the next round up

[@trg1408]

I just recently changed my ram speed to what it's supposed to be and then I went to change something else and It just won't boot into bios, or it does and i get no input signal. Here's the kicker though, I can boot into the OS and get a signal. I'm wondering if this could work. I don't want to screw anything up any further. Should I be good?

[@mikesunboxing]

try plugging in another monitor or use a different cable it is a common hdmi / dp / monitor bug

[@trg1408]

@@mikesunboxing It was definitely a bug, and I managed to fix it and in the process do everything else I wanted to do. Thanks for the input! You're videos are becoming very helpful in everything else I am learning through the process. Cheers!

[@mikesunboxing]

@trg1408 thanks appreciate that glad it is working out for you now

[@patricklebel1141]

Reseting the bios is an overlooked problem solver. But the question is... How come there is no protection to prevent the mess?

[@mikesunboxing]

yeah the "logic" or lack of in computers is frightening, don't worry AI will update the BIOS on boot soon

[@OlettaLiano]

Usually, the mess comes from people who don't know what they're doing. You can't really foolproof human tampering.

@@mikesunboxing Thanks for the invite. I was able to solve it by applying much force by a screwdriver. I broke the hook and cut my hand but now I can easily remove and put CMOS battery 😃
