Omyghod!!! Thank you so much for this!! Im literally crying, my laptop is working after I did this!! I've been trying to fix for a year now and this is the only video that worked!!! Thank you!!!

Thank you so much! Fixed dads laptop using this method and your other videos! Your a legend saved us £700!!! People like you need a medal, giving out free advice that has saved us a lot of money !

Thank you so much for this video! I have an older IBM ThinkPad X220 that wouldn't start properly. The WiFi light, then BlueTooth light would flash in that order, then the fingerprint reader light would turn on but the laptop would never start. I was about to give up when I found your video and thought I would just give it a try since I had nothing left to lose. Lowe and behold, removing the CMOS battery and reinstalling it fixed the issue. I would have never expected it to work but I'm very happy it did. Thanks again for taking the time to record and post this tip!

Your help was much appreciated my friend. Unplugging the battery cable and then plug it in again did help me. Back in the past when the cellphone got stuck we used to do the same thing by simply taking the battery out. Unfortunately, everything is irremovable nowadays.

You have no idea how much of a life saver this video is

Thanks man! I was stuck for 2 days. Trying to troubleshoot what the issue was I had disconnected my inbuilt battery thinking that was it. It it was actually my cmos battery!

Thanks a lot! Used Novo button as suggested by Lenovo website but no response, just blank screen. It occured after restart from firmware update. keep up the good work.

Thank you so much. I just managed to turn on my computer again.

Thankyou for your useful tutorial video. Thnx

Thank you very much, it is fine again. You are a star!!!!

Great video man!🙌❤

Thanks for the video, your fix works.

My Mum has a Toshiba older Windows XP PC so if not I might let her have my old laptop and I’ll use the Mac and my iPad Pro in between depending on what we want them for!! But if not the Lenovo my be sold on for spares or repair. But I’ll see what I can do thanks to people on KZfaq have really helped me and I’ll let you know the resaults if I get stuck on what to do I’ll ask and view KZfaq how tos videos.

EXCELENT VIDEO!!! SAVED MY SEMESTER!!!

Hi I have the following problem, A thinkpad t430 does not turn on, only the fans move for 1 sec, and then it turns off. I changed the motherboard, but the problem persisted, do you think it could be the cmos battery or the power connector jack? Thanks for answering

My laptop has a light and when I plug my charger it has a light inside the motherboard but not turning on. I’ve tried all links in your description.

Frome Iraq.....I would pay 25$ for this disrupte With out you thank you for this clear and accurate job. What makes you special is that you give a lot of salutations of repairs for one disrupt and one will try these till he will discover what is his problem. Thanks

THANK U SO MUCH BRO. IT WORKED. GOD BLESS

Thank you for the helpful video! Where is the link to the followup video about accessing the BIOS utility to reconfigure hardware settings?

good for ressting bios from a school laptop thanks! 😊😊

Thank you very much for this. It works for me. The problem is that whenever I turn my Lenovo T450S off, I have to do this procedure to get it to turn back on. Any thoughts on why that might be? Should I try replacing one or more of the CMOS battery, the internal battery, the removeable battery? One thing I note is that, when following your procedure, after plugging the power lead into the laptop, but before pressing the ON button, the ON button light shows steady green. I don't think it used to be like this (but am not 100% sure). Thank you in advance for any help you may be able to give.

Thanks pretty much bro... From Sierra Leone

Thanks so much, saved me so much hassle taking mine in to a shop. Will ensure it gets shut off properly before storage from now on. If problem comes back/persists is there another diagnosis?

hi, i have a lenovo ideapad 320 15ikb, and i want to go back to the previous bios. To do this I download the previous bios and run it? Or there is some different process to follow, or some consideration to have. Thank you

hello good day sir can i ask how to reset the bios in lenovo g50-30 non removable cmos battery after its bios update the laptop showing no display when its reset you can only see the flash in the camera and hearing the HDD running

What should I do if I'm stuck in the phoenix securecore tiano setup I try fixing the date and stuff and saving and exiting but it just brings me straight back to the setup screen how can I stop this and be able to use my laptop

I have a Lenovo ideapad s340 15api I bought this used and it wouldn’t turn on without it being plugged into AC adapter. So I purchased a new battery and replaced it. I noticed the battery that was previously installed was the wrong model and figured that would be the issue. Now with the new correct model battery connected it still will not take a charge. It won’t even appear as “charging”. But When I disconnect the battery and plug in the AC power it will then show up as “charging” but with no battery connected. It will not let me update the bios driver without both a battery connection and it being plugged into a AC power supply. Any advice will help please and thank you !

Hello I have samsung laptop model number NP300E5V. I enabled secure boot and tweaked other setting but by mistake I am no longer able to access the bios. I removed the CMOS battery for a while maybe 10 min with no results. ANY HELP

thank sir

would this fix my lenovo laptop that turn off before the start up logo when turned on?

hey bro happy new year

Can you tell me if my lenovo g560 20042 modelhas a cmos battery hidden in the other side of the board? I dont think a designer with the right state ofmind would have botheredto design an acces port on the bottom side just for the ram ,hardrive and wifi cardand leaving the battery on the otherside which would require dismentlong it completly ea really bad idea for alimited lifespancompnwnt specially for a partew

I have a lenovo edge 2 and after a year it’s having a notification in the bottom right corner that it’s not charging so I guess it’s just the charger so I bought a new one and still having same issue. I took it to a pc repair shop and they look at it and try first if it’s the charger input but turns out it’s not and they said it probably the motherboard. I can’t afford to get it fixed so I kinda forgot about it and after 2 yrs I pulled it out in storage and try plugging in ofcourse won’t turn on and power light just blinking so I watched your video thinking maybe I can revive it by removing battery and cmos battery even the pin reset and still won’t power on light still blinking. Do you think it’s just motherboard really needs to replace?

how to solve intel power cycle in lenovo laptop E41-25 model plz help me .

Thank you!, It really helped me, but I want to know about this BIOS, what are the causes of this problem? Because this often happens to my laptop.

Thanks so much, worked a treat after trying all steps from your 1st video, my question is why does this happen? 2nd time in 2 weeks, its an old thinkpad E440, last time repeatedly keeping the power button down, it finally booted, this time, nada till I unplugged the CMOS battery that thankfully, was under a panel on the underside and I didn't have to go through all you did on this video. But why is it going into this shut down non boot mode? Red light stays on, but just blinks 3 times. Is the motherboard about to go? or is the power switch on its way out? Thanks in advance.

I have a Lenovo flex 11. That gets hung up on boot. I eventually get a blue screen of death saying that the computer needs to be reset. The it goes into restoring the pc. Then gets hung up again. I pressed the reset button and held it till the power light flashed. During the bios boot it says that the system cmos checksum is bad. Then it goes back to getting hung up on boot. And saying that it needs to be restored and encountering a problem and reboots and repeats. I unplugged the cmos battery and main battery. The cmos batter is 3 volts. I went into the bios and set that to default. Do I need a new mother board? Or is there something else I can do? I can’t get the computer to boot from a usd pen drive with windows. And I cannot get it to boot from a windows 10 install dvd in a usb optical drive

The battery is the same, but fallen of from that piece of metal, i unplugged it, but the baterry still needs to be atached tu that piece of metal, or i can just plugged and that's, i ask this because i'm sure that's the problem and my laptop won't turn on

Thanks. Would this remove/reset a locked bios?

I have a Lenovo Flex 2 14. Last night we streamed a movie from it. But today it doesn't ON. When charger plugged in, power light only is on (white light) but the laptop won't turn on. I tried 30secs tricks for power button and reset button. Removed the Cmos battery and Internal battery then put it back again but still not opening. Nothing change. Pls help

i need the location for the lenovo g50-70 laptop

I have lenovo g40 80. It's really running very well but I cannot get in into bios because of system password that I really don't remember at all. I need to get into the bios to activate the "virtualization". Do you have any idea at all to bypass the system password? I'll be glad if you can help me.

Jamin, trying to fix daughters laptop and discovered your vids. Great video but laptop still not starting. Checked charger and internal battery following earlier vids and am a few steps forward! Power light stays on and is white (was amber) and the on off light has stopped flashing when I switch on - but now just comes on for exactly 5 secs and then goes off? Screen remains black throughout. Any pointers please?

I have a Lenovo G580, which was password protected both in the bios and the HDD, and running ubuntu 18.04. I replaced the HDD with a SSD and everything seemed OK. Now I notice that I am not asked for a bios password. I can live with that, but there are two nagging issues. The earlier HDD was encrypted, and now I cannot use it using a HDD enclosure. It does not get recognized. The second issue is, I can't get into the bios setting by pressing F2 at all. I can get into the OS selection using F12 sometimes, but just cannot get into bios setting. Is this related to the bios password issue as well? Will a bios reset using the coin battery approach help? Thanks in advance for any help.

Hey there. Great videos. I have Lenovo Z710, almost 5 years old but not used very much. I had my laptop in a cold room for two days and then when I brought it back to the warm room it won't start. The power led was not glowing, no response from power button and from one key rescue. I fixed it with the removing of the CMOS battery and replacing with a new one. But 2 weeks after that, again in a cold room for 2 days and it would not start again. Dead. Tried the same things, pulled of the ram, but still nothing. Left it plugged in, and 15 minutes later started by itself. Ask several repair shops, and got different diagnosis. From cold solder chip to problem with some "input output controller". At this moment the laptop is working fine... Could you help me if you have had an experience like this? Thank you in advance. Best regards. Lazar

Hello, I have a lenovo just like this one and as you know the battery is under the motherboard. My computer blinks and does not charge and it's not my chargers. Will this help my computer to charge? I hate to take it apart if I don't have to.

Hi, this always works for me on my lenovo y520, but every time I turn it off it doesn't turn back on. The truth is it is annoying to be disassembling every time I want to turn it on, do you recommend changing the cmos battery? (I always disconnect it for about 10 minutes and turn it on again)

Yo thanks man!! It works! But, after I shut down, its completely dead again.. which means every startup I have to unscrew remove everything again to reset my cmos. 😣 Any permanent fix for that? Thanks again..✌️

I was doing a Biso update and the powercode was unlung by accident now the power comes on but screen wont come on...will this work for my computer

I have a question please, if that CMOS battery with cable and stickers wrapped on it, if you unplugged it, would it still have any electric contact to the motherboard? As long as it is still placed on the mother board? I need to make sure not to have any power activity running on. Thank you.

Can't seem to locate the CMOS battery on a Lenovo Ideapad P400. Removed the motherboard and couldn't find it on either side. Please let me know where I could find it to reset. Thanks!

Hey, mine's stuck in repairing mode but it had been like this for days. What if I do not have any CMOS battery to replace, can I just plugged and un-plugged it? Thanks

Hi anyone please help my Lenovo 130 laptop was stuck in bios update for almost one hour and I removed the battery to save the motherboard from burning and afterwards when I tried to turn it on(press and hold power key for 3 seconds number lock key turns on and then turns off, if anyone has the solution please share it would really help me, thanks...

Hello, I just recently serviced my Lenovo Y700 laptop, replacing thermal paste (I have done this before). And when I finished the laptop does not turn on and stays on the black screen, if I try to turn it off, it does but again after a minute it turns back on automatically and the same happens if I connect it directly to the AC adapter. Could it be a CMOS battery problem?

Would this still reset if the big battery was still plugged in but not the cmos battery

Hi, my Lenovo IdeaPad 110 is not charging when the laptop is on. It only charge when its off but sometimes it only charge up to 90%. Any recommendation? Thanks

Tried your fix because we got a black screen after a bios update. The laptop is a 2020 lenovo ideapad 330-15ast. This didn't work for us. We have power but keyboard lights are out and still a black screen. Any ideas?

Thanks. CMOS Reset button worked. Backing up everything right now:)

On my y530 I have the same cmos cable, but no matter what I do it won’t come out. It’s like the worlds tightest cable. How the hell did you get yours out?

My Lenovo ThinkPad W530 turns on and the fans start going, but it doesn't boot at all. I had taken Windows entirely off it to do a clean install, but now I can't even get into the BIOS. You talk about this kind of problem early in the video and say there's a video I should look at, but I don't see it in the recommended ones off this. What's it called?

Does this work for a Lenevo Thinkpad x260? Tried everything for the first part, yet it still didn't turn on. Only thing that happened is that the power button flashed green 3 times.

please help me. My laptop won't show anything after opening it from power button. It runs for a while about 15 sec ( the sound of fan) then the fan and pc both shuts down automatically. I am using direct working ac current as my battery is preety much dead . Will unplugging CMOS fix this bro ?

What should we do if the bios battery is a button battery? I have a Lenovo G50.

Hello sir. can i use it to reset bios password?? I have z510 IdeaPad.

Okay, I'm not sure if this video will work for me, and it seems like a long proscess, so im going to explain my problem and please tell me if this will work for me. So my problem is that when I was updating my BIOS (I didn't know BIOS was an important part of the computer at the time) it was taking a while, so I just shut my computer, and now it's not turning on.

Hey The display of my lenovo y-50 won't turn on after it is shut down or if the battery dies. But if the laptop hibernates or goes to sleep mode, there is no such problem. I tried disconnecting the CMOS battery and now it works fine. What more shall I do?

Hello Good sir, I was working on my laptop Lenovo Y50-70 touch. I noticed my computer had gotten slow. Since I had experience with installing windows and curious about the inner workings I tried to do a fresh install of windows. I followed several guides on BIOS setup to change boot order to my Bootable USB drive. Everything looked like it went well. But I had already formatted the hard drive on a different computer. And thought I'd do a fresh install on an empty hard drive and using my USB drive. But after I plugged my hard drive back in the laptop and pressed the power button there's no post at all. Wanted to know if a BIOS reset might help me with the same. I'm away from my home right now as my father in law expired but will be back home in a month. Could you please help me out? I promise I understand computers and willing to learn new things. My main doubt is I might have changed the BIOS settings. So the technique in the video seems like the the right way to go trying to reset it. I've showed the laptop to several service centers but they don't listen to the problems of the customer. I've told them this before yet they don't try it. They said the motherboard is dead. But everything can be fixed given the time and effort and parts replaced. Please help, Thanks in advance.

I replaced the battery on my lenovo edge 2 1580. Laptop wont turn on unless its plugged in to the charger and it takes some time to get enough juice to turn on. Sometimes I have to unplug other things in the room for it to actually turn on. Battery has an X on the bottom right corner but when I click on it it says 100%. Let me know what I should be doing next. Thank you,

Any idea where the CMOS battery is located on a Lenovo Ideapad P500 Touch? I've searched endlessly, to no avail. Your help would be greatly appreciated.

my old toshiba satellite pro l850 laptop has RTC battery low error even after replace old battery with new one. also two usb ports are not working..only one can use...someone suggest me to update Bios..it has BIOS Version/Date Insyde Corp. 6.30, 21/09/2012. when i search and found there is a vers 6.60 out there.but when i going to update it,dead battery stop going further.. do you know any trick to bypass No battery error?

Hi brother, I just subscribed to your channel and I have removed CMOS battery as well for more than 2 hours but still BIOS is locked. Please let me know how can I remove it any other way? I have Lenovo s230u model, please guide me 🙇

Thank you for the video. It is great. However, I followed your video and replace a new CMOS battery. It still doesn't work. Do you have any other advice or video? Thank you.

How can l turn off (PEX) my laptop is not responding to F2 keys

Could this affect the monitor display? Same computer, screen glows but no display. Can see the functioning display if using an external monitor, but nothing on the main screen. What led me to this was that the clock needs to be reset every time you restart the computer. This makes me think the cmos battery is dead, and needs replacement, not reset.

I’m to scared to do this I really don’t know how to put it all back together and where can you buy the metal coin with the string I’m sorry I forgot the name

Hi, Even after removing my BIOS and main laptop battery, it is still asking for a HDD password? Is there a fix for this? Thank you Martin
