How To BIOS Reset Lenovo Computer / Replace CMOS Battery - Computer Wont Turn On Fix #2

hey guys this is Jamin with point tech we're bringing you another computer do-it-yourself repair video today let's say you're working on a Lenovo laptop that won't start and is completely dead this is a common solution we're going to show you for if you're a laptop again it's completely dead it won't start at all if your computer does stop part way if you hear fans turning or or if anything is starting part way we have other videos for that there are specific repair videos for specific issues and this video is specifically for if your laptop is completely 100% dead now this is a more intrusive fix than our other video we do have another laptop repair video in our description a no power fix video try that first and if that doesn't work then come back here and try this video because this video will involve getting into your computer a little more than that one so save it for last um so every laptop is a small battery on the motherboard called a CMOS battery CMOS that supplies power to BIOS or your base system even when your computers off I'm going to show you how to go in remove that battery which will cause BIOS to reset to factory settings and that can sometimes help your computer revive when it's completely dead now don't confuse a BIOS reset with a system reset that has to deal with your operating system we're just dealing with the BIOS system right now now every computer will have one of these on the motherboard this these are examples of seamless batteries this is a loose one which is more common but you'll also see this every now and then especially on some older computers it'll be wrapped and I'll have a plug into the motherboard but that's what we're going to be looking for so on this laptop as you can see there's no panel sometimes it'll have a little panel that I can access in order to get this battery this unfortunately doesn't have one so I have to take it off so we're gonna take out all the screws take off the bottom case or the palm rest however way this computer goes and we'll show you where this the most battery is you I took my pride tool and I went in between the palm rests and the bottom case there comes that aside so there's the inside of your computer here's my battery it it was kind of an external and internal battery it's on the outside so it's external but you can't unplug it it's not removable so to be safe I'm gonna follow this corn in the motherboard right there I'm gonna unplug the motherboard from my battery here I put the battery for my motherboard out there so apparently there's no seal spatter here it's on the other side so again no more intrusive fix I'm gonna have to take the motherboard out to get to the CMOS battery so I'll start unplugging things I already unplugged my battery well unplug my uh whatever this is that out unplug this little ribbon cable now these will have a little plastic very fragile a little plastic clip that pops up it's fragile so I'll be careful with it there we go slides right out and then I always slide them right back down so I don't break it this one also same thing pop it up looks like a keyboard also gonna have to take off my Wi-Fi card cuz that screw down gonna leave my antenna plugged into it though disconnect my fan a lot of things to disconnect in this one I'm gonna leave my RAM in there's no screws under there so I've unplugged everything oh never mind I'll I take my hard drive out as well that's plugged into the motherboard hard drives will usually be in caddies like this so unscrew the caddy you can leave the hard drive in the caddy if it is just take it off of the motherboard again your computer will probably look a little different than this but all right I'll start taking out the motherboard you it'd be very careful if something seems like it's not coming be patient you'll figure it out don't want to break your motherboard all right so flipping this over here is your CMOS battery this is one of the ones we showed you again it look like either one of these two and that's that's the one you get right there so what you're gonna do you're gonna unplug this CMOS battery just like that if it was the other kind of batter you'd have to physically remove it from your motherboard but we can just unplug this one you're gonna leave it that way for 15 to 20 minutes and then reattach it and close your computer back up and that should be sufficient to reset your BIOS now if this was successful you'll need to access your BIOS utility and reconfigure some of your Hardware settings such as your date and time there's a video in the link below that will show you how to how to get in there and then change your date in time however if this doesn't work in your computer still does not turn on there may be another issue we have some videos down below on testing your charger first of all then testing your power jack and diagnosing other reasons why your computer may not be powering on but if this was in any way helpful please like and share if you enjoyed do it yourself laptop videos please subscribe and thank you so much for watching
