This is just the first step. Next step is to locate your EEPROM (which is different for each Lenovo model), then short circuit the 5th and 6th arm on the chip when you see the Lenovo bios boot screen. That should sneak you pass the administration password so you can set a new one. I've successfully did this on the x201and x220 and a few older models. The only model I've had trouble with is the x100e.

Man, I just love the design off ThinkPads!!! No way the chinese would have come up with that all by themselves.

I've been asked to look at one of these. It was bought preowned off a site like gumtree. The buyer wasnt aware of what to look for and when he met the seller he showed it power on and made the sale. It's locked before it boots. I can get into a very restricted bios menu but can't really edit anything. I tried to boot up a live USB operating system to just try to get it booted up then go from there by basically doing a fresh install of their choice os. It reads the usb devices and shows them on a boot menu but it won't allow me to select them as a boot device. So i went down the route of an arduino based bios chip reader to try and attempt to find maybe some encrypted data that may lead to a pin. Or I thought about swapping outnthe ssd card (no hdd) and maybe even trying to reflash a new bios and os that way. Or using an ssd card reader to attempt to read data somehow but all this was just ideas and I've never really done anything like this. It's a lovely laptop and the person has basically said if I can fix it I can have it. I have a nice laptop so want to fix it if possible a d give it back to him with no cost of repair because of what happened to him. My gf fell for a similar trap when my computer broke and I had a uni assignment due next day. She tried to save the day and found a cheap laptop. The dude must of edited the photo on the ad and cropped in a windows desktop image over the screen. Then when he came over it had barely enough battery to turn on and he conveniently didn't have am adapter for it. She thought at least it powers on. I will sort an adapter. I found one, powered it up and indont know what he did but there was no operating system he somehow deleted it lol, it just booted into bios if I remember. She was so upset she thought she was helping and I had to now fix the thing. Made me more determined. Had an adapter for it and I had a USB with Linux Ubuntu live os. Took me all of 10 minutes to get it running an os. People are such scammers it's terrible. I had the last laugh. It was decent spec and he tried to ofoad it as a last resort I think, assuming it was beyond repair. Same night I sent him a video of it working and running sweet. And got my assignment typed up and emailed in time 😂

Excellent! I sometimes get so frustrated when I dont know which screws are stuck so this helped a lot.

Great ! .... Thanks so much Mr. Mike Dancy Resolved this Problem ! ... How is about model X60 ?

Well, what is done here is a reset of the "PowerOn" pw option, which is set in BIOS. My comment to this article is, that you don´t have to wait 15 mins, after disconnecting the CMOS backup battery. Disconnect the CMOS-battery and short the 2 pins on the MOBO connector with a piece ( pincet etc.) of metal for 2-3 secs, and that does the trick. REMEMBER TO DISCONNECT MAIN BATTERY AND PSU BEFORE SHORTENING THE PINS. I have done this on a large variety og Lenovo Laptops and the solutions has worked every time. PLS. note, that if youre dealing with a forgotten "HD PW" code, this solution can NOT help you - it´s only ment to reset the "PowerOn" feature...

power loss is not supposed to allow password removal. you claim you already did it before this video how convenient...but not for us who need proof

Thanks for the video. Is there a permanent solution to this if I do not want to remove the CMOS battery for a while. Thanks

a heck of a lot smarter than the indian guy who does a complete teardown to jimmy the eeprom! did you have to take note of anything, like hard drive tables or whatever? or does it just auto-detect all that when it gets powered up again? (cmos battery is pretty much what I would have thought to do, I just didn't know if modern computers still have the separate battery for the cmos memory or if it was integrated now or direct-soldered or something like that. I'm old-school - haven't touched this stuff in decades)

Followed the steps, system clock reset, but the password is still active.

By disconnecting CMOS will not clear the Bios password Only one way to clear , we need to perform chiplevel work We need to remove the bios chip from motherboard and need to reload the bios to chip by debugger device through bios software from Lenovo website I have 5 year's experience in Lenovo products

Hmm I thought laptops have a special chip called EPROM where the bios settings are stored. Do you know if that's the case for a Lenovo 300e?

Excellent work and explained

Question: why did not take out the large battery? Excellent video.

How to reset SVP on my Lenovo T440p as this Cmos battery removal is not working.

Hi , The Lenovo Lap Top A485 has a different Mother Board Layout Any recommendations for A485 Thank you

THX for the video

Bios lock is identical to this, but upon dismantling my Lenovo X1 Carbon 3rd Gen it’s totally different inside to this. I disconnected the batteries & what looked to be only similar connection (which) I hoped was the bios battery. & the main flat pack battery inside. Waited 20/25 mins. No “DIFFERENCE” still has bios lock.

mi lenovo ideapad 330s me pide contraseña en la bios. como podria saber la contraseña o restablecerlo.

I've just had the same issue on a R61 - this method didn't work HOWEVER shorting the EEPROM as it booted worked and all fine :)

Thank you

the lock screen your showing is a supervisior password not the bios removing the cmos battery may help with bios password but not the supervisior password

I tried this method on lenovo ThinkPad X200s it doesn't work which on can i use

Appreciate your help

So IDK what Gen or model your working on here but it’s not an X1 Carbon 3rd Gen As it’s identical to look at externally but insides are total different

Does it work on ASeries desktop?

This works for POP (power on password BOOT-LOCK) only and doesn't remove SVP (supervisor password BIOS-LOCK) NOTE!!!: if your laptop has a SVP and boots up without POP, following this password to reset POP will retain your SVP and reset your POP and clock REQUIRING SVP to boot. This may mean that your laptop may stop booting if it was booting before.

I tried once on my IBM R52...to no avail; but I know this works. I haven't done it in decades, so I wanted to see if I forgot a step. I came here to see if I missed a step & I haven't...so I will try a 2nd time. I use LINUX Tahrpup 6.0.1 to start up ALL my old pc stuff (don't know if that's why it didn't reset), so it's odd that my R52 did this to me...I use it often enough.🤔

Im having a problem with the black screen log on password of my Lenovo B590 notepad.I can't unlock the factory password. Please help me with some hints

Removing the cmos battery does not work on machines which store password in rom, may even make thigs worse (also lock internal drive with SVP if they support it) Either read out&decipher pwd or overwrite rom with known pwd/clean data

no

thanks bro

Didn't work on Lenovo L512

Hi Mike, I have tried replacing cmos battery and SSD but still no luck .. asking for bios password .. Model Lenovo t440

do you have lenovo t440p bios password solution????

The one my dad got it’s has a lock a hospital computer I can get it to safe mode for I can unlock it

are you remove the battery CMOS with the new one ?

I intent to install Windows 10 to replace original Win 7 on my X220. The only concern is, if X220 unable to perform as machines already reaching 5 years old (2012 - 2017). I did some housekeeping, replacing with SSD, and adding RAM makes it total 8GB, but still not convinced.

Dude I have the same Lenovo than you I did it like 3 time with the Batterie on without and even let the cmos unplug like 2 hours long and still the damn thing at launch...

Do same but don't remove bios pw
