Replacing a CMOS Battery in an Older Machine

- I got a new video camera, and my old desktop-in-the-basement needed its CMOS battery replacement. Combining those two things resulted in this video showing how I replace the battery.

This video helped me confirm my assumptions about my sisters pc,
it arrived without new thermal paste and its a decade old system with a 4790k and a gtx 970, the fans didnt spin, the cables werent managed, the drive wasnt screwed in, the cooler was wonky, and there was a freaking dead moth in it, R.I.P.
after cleaning it up and fixing it, i loaded an ssd with a rufus windows 11 requirement bypassed os and it just worked, however this issue as seen in the video was a problem
i made the mental connections of cmos battery and clearing cmos and whatnot so eventually i did some web surfing and found this, almost confirming my suspicions
a temporary solution i made until the cmos btry comes later today is that i deselected the option that shows the f1 error screen and instead it just restarts and boots to windows
this is obviously not ideal because my settings get deleted every time even though the end user doesnt know anything bad happened, im very grateful to the goodsir that made this video, i thankyou, otherwise it may have taken me a few more days to think on my own what the problem is, and the user of that pc would not appreciate that, thanks :)
I think touching the case to prevent static electricity buildup only works when your power supply is plugged in.
unless you're on carpet or wearing very fluffy clothes, what he does is probably fine, if not then i made an oopsie as thats what ive been doing since i got into this niche
@@Seizuqi No, I agree that most people don't need to worry about it. There is a Linus Tech Tips video where they shocked themselves while working on a computer, and even shocked the components themselves, and most of it was fine.
It's been a while since I saw this video, so I forgot what my comment was specifically about, but I assume the person in the video said something about anti-ESD straps and not having the power supply plugged in.
I also don't worry about anti-ESD equipment when repairing my electronics.
Thanks. I just changed a 13 year old battery - and it worked :)
Thank you for sharing your expertise. Happy New Year 2023👏👏
Thanks, I finally found the battery in my old Aurora ALX.
Thank You, so much will Try this out this Sunday...
Hello Leo: In taking out battery you used a small tool to pry out battery after pushing small catch back. What tool you use ?Where did you pry the battery at? My battery won't just come out by pushing catch back!
TLDR: My computer wouldn't boot up and replacing the CMOS battery fixed it!
In case anyone else has the same problem I had, my computer (it's old) would not boot for nothing. I switched out the power supply (wasn't it), replaced the power switch cable since I'd had an error message for that (wasn't it), and bought a new motherboard and was about to swap that when I learned about the CMOS battery. I replaced it, plugged it in, and the power supply kicked on and off repeatedly a few times until it finally stayed on, and the computer booted up all by itself. I didn't even press the power button. I was in complete shock that it fixed it. I did not have to remove anything to access the battery. I thought for sure I'd have to remove the graphics card but when it was not coming out, I decided to try to do it without removing the graphics card. I used needle-nosed pliers to squeeze the tab & release the battery and it popped out. No problem. Also, I never changed the BIOS settings so them resetting wasn't a problem.
Hi Leo....I have a DELL XPS 8700. I purchased it in 2013. Was wondering if you think I'd need to change my CMOS battery? Also when you put in a new battery....do you have to reset the date and time? Not sure if that came up or not? Thanks for your videos they are very helpful!!!!!! :)
Amazing video! Thank you so much!
Great video Leo!
How did you put it back in so easily that's impressive
Thanks was worth a try changed battery still nothing won't try to to start . So not power cord not battery .Must be something else ?
You are legend sir.. thank you.. this video details and informative
hello . why didn't you show how to change date and time and boot drive sequence? also why didn't you press f1 to get into setup ? as i need to know how to do it cheers
My easter present to my sister is a cmos battery to fix her computer, i swear im such a shit big brother lmao
I watched this because I have 2 OLD machines I want to change them in. One of those is this computer I am typing this on. I just upgraded the chip from Sempron to a Phenom II. It was definitely a good move. This old machine got a new spring in its heal. Thanks.
What if the time and date are not visible in bios?
But... but... I wanna see the new camera you mentioned here!
Y'all need to listen to the TEH podcast. It was discussed. :-)
I replaced the battery now no display on the monitor, powers on but nothing show up on screen.
I’m changing my 1-2 year old battery… idk why I need to, I think I turned pc off when it updated?? But idk why it’d affect it
How do U place the battery in ? Just push it in ?
Yeah just push it in. Sometimes there's an audible click when it sits in place and won't come out. If it comes out then it wasn't seated correctly.
Sir i remove the cmos battery and put it again in motherboard it show no display in monitor
I recently noticed my desktop is losing about 4 seconds per day. This PC is rarely tuned off, and rebooted only every so often.
Is this a sign of a dying battery backup?
I wouldn't think so. If power is always on then the battery shouldn't come into play. I'm not sure what might be happening here. Make sure you have "Set time automatically" turned on in clock settings.
after removing/replace CMOS battery 8 beep error stopped and NO USB power to KEYBOARD or mouse
i have a computer which when you turn it on it immediately goes into power saving mode and shuts off. Could this be an issue with the battery?
Absolutely.
My computer simply won't boot. Going to try to change the cmos battery first.
Will a dead CMOS battery prevent a laptop from coming on?
It might, but tyically it won't. Usually what happens is that your BIOS Settings are lost, the time is reset, and your system boots using some kind of default setting (or at least displays some kind of error at BIOS startup).
@4:20 - replaceing cmos battery
Thank you LEO, you are awsome
My battery lasted 4 years
