Thinkpad R50E owner here. Some of the screws are numbered, some are not, and the ones that are not, they are of different size, to just place them in a position that you took them out, it's gonna help you later. I wasn't able to fully detach the keyboard and the plastics, but I was able to lift it up from the bottom side so that I could take the old CMOS out, and put the new one in. Then screwed everything back in place, the keyboard still works, and I'll give you an update as to if the new CMOS from Ebay works.
Powered it up today, no CMOS date and time errors anymore! Works brilliantly. But it's a shame that the CMOS is so buried, saw a video on another Thinkpad and it had a CMOS in the battery slot or something. Like you just take the battery out and there it is, no need to unscrew anything. Still, this was easy to follow, glad it worked.
Or u can do also chiper and that same - no buy new all part witch cables - get old open the protect foil change to the new CR2032 battery and again witch that same foil old foild it and of corse need to hold old foil use some tape to hold (small part use on 1 side to hold foil on please ) then connect to laptop and END
Monica Cuartas no thats the administrator password thats the most hard password to erase.. you will not do nothing whit remove the batery what you need to do is erase or confuse the eprom memory which is the place where that key password is kerp it.. becasue evene you dont have batery the key will remain there i have the same problem i have a thinkpad t40
@@cezarpo Hi Monica, this post is a little old, just my two cents;.. A few years ago I unlocked a T26 Thinkpad with the administrator password, .. I identified the EPROM chip where the password is stored, it is a SMD EPROM chip so ordered a blank brand new, and had to use the heat soldering gun that replace it. Also the password is married to the hard drive controller plate, in that way it locks the hdd also, it mirrors - compares the password between the EPROM chip and the hdd for higher level security.. So I also had to discard the old small in GBs Hard drive with the password,. Smoth and good quality my vintage T26 Thinkpad, I still enjoy using it. Cheers and good luck. Hola Mónica, hace tiempo yo le quité ese password a un Thinkpad. Primero ordené el EPROM-bios chip correcto, lo soles con antorcha de calor puesto que es una miniatura y el password del administrador se casa también a la placa de control integrada en el disco duro para compararla así con la del chip, remplace el disco duro con otro y con más GBs. Son tremenda calidad ésos laptops, suerte...
Monica Cuartas pudiste hacer algo?

buenos dias chicos, reemplace la bateria pero ahora cuando quiero encender la pc. El ventilador se mueve y se apaga pero no enciende. Apreto F1 para entrar al BIOS y no hace nada. Me podrian ayudar?. Que hago?

Thank you. This is much more difficult than replacing cmos battery on T23 (one screw to remove).
Very helpful and easy to follow. Thank you! Like other reviewers have commented, I really appreciate you taking the time to provide this video.
Why we've to change it.
@@maniraju9818 because the BIOS settings like time and stuff dont work without power.
Thanks for this! I just replaced the battery in my 15 year old T43, it's like new! :-)
Same!
ITJungles, It's the same way and the same battery for X61, T43 and T60? Any cheap generic battery will suffice or are there some better than others?
This is just what I've been looking for -- thank you!
Each screw hole is labelled with its corresponding screw size (1 to 4, 4 being the longest) so you can't mix them up.
@Little Pug : thanks :))
I know, just wanted to comment that :)
Thanks!
Thank you so much!
Thank you, it is helpful.
Thanks for your video
Great video. Very helpful...Thanks!
Great, thanks for making the video!
Excellent, very helpful. Thank you.
it's helpful to me,thank you very much.
Does taking the battery out and putting again reset the password ?
Use a normal 3 volt lithium battery, make use the polarity is right and you have a good contact, Use tape and a small rubber band around it.
Thank you so much
You're most welcome
Use una hoja blanca blanca para los tornillos ... y trace una linea para cada fila de tornillos asi no confunde donde deben ir al ensamblar nuevamente
Thanks but can i use that model of cmos battery in other laptop? i want to chage the battery the laptop is a dell inspiron b130

My laptop is showing 0190critical low battery error... Should i replace bios battery??
thank you very much for your help
The battery is 3V, you can use any battery with 3V that is small enough!
my suggestion, put the screws on a white paper so you see them better and do not lose ... and count them
Thanks. That helped.
I got a little lock on the left hand side of the screen. Do you know if I replace the battery that can resolve the problem ?
