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

Wi Fi erra do I still need the pro cd? my friend uses his for wi Fi. I don't have pro disc.

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

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?

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

Excellent work and explained

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

Does it work with the Lenovo thinkpad x61s or has it a fix?

I very much appreciate you on this tutorials, but please can you help me out with 'Hasse Avante' laptop? i want to discharge and connect the cmos battery like you just did. thanks

Please how can do same on my Lenovo think pad edge E420. I tried it with this method and it didn’t work. Please kindly help me out plsss

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.

I have a lenovo T530 laptop,looks like yours.asking for supervisor password to install bios updates,I don't know it.Think it will work on mine?

I have the same problem SVP on a t470 someone help please i would appreciate

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 😂

i have the t23 one does this tutorial work on my device ?

THX for the video

Hello frd I am using lenovo b490...it working well before update the bios...after update its not working...If i turn on lights on the power button..but no display...Can u tell me why...

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

i have some question. where is location cmos on laptop lenovo type L421?

this will work on a T500?

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...

Thank you

Hi, I have Lenovo Thinkpad X270 with supervisor/Bios password. Please help to unlock.

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.

This no work this password is programmed in the bios!!removing the cmos battery won't help!!Thinkpad W701!!If someone knows where we could acquire these passwords it will be perfect!!

GOD will BLESS you 😇💕

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 :)

Sir if we do like this method.... Our files and documents in this laptop will b deleted ah??plsss reply I need a solution for this😭

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

this does not work for a bios password

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)

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

Is it works for t420

For Thinkpad x100e pls guide
