Hello allservice.ro,
this is the first time I'm posting on this awesome site, you guys are awesome!

Anyway I have a Lenovo W500 locked with supervisor password and I need to unlock it.

I have already read your guide "How to unlock ThinkPad supervisor password" but I'm a noob in eletronics, so I need to be well explained.

I need to find the cmos, and next attach the cables.
But how to do it? And if i do it wrong, there is a chance to retry the operation without damage to the system?

Last maybe you have a picture/scheme for cables in my model?

Please le me know. Thank you!

Hello,

Use the forum's search, also see the tutorial again. It is everything explained there. If you can't cope with it then ask a friend who knows some electronics.

Have fun!

Thanks for your reply Victor!
Yeah I read the tutorial like 2000 times but I don't get some things.
Can you please answer me this questions?

- how to solder to the eepron is clear, but in the other side I need only to connect the serial like this:

eepron <-----> serial

or

eepron <------> board? <-----> serial

- After the job I need to remove the cables from the eepron?

- The eepron on my board is 8 pin, so it's a 24RF08?

- I risk to shock the board and myself?

Please, please answer me! I really want to know how to do it.

P.S. Sadly I have no friends with electronics skills Crying or Very sad

Perhaps you need to hire some polish guys. Or maybe not, LFOL

You->Software->PC(hardware)->COM1->Interface->chip.

- After the job I need to remove the cables from the eepron?
Yes

- The eepron on my board is 8 pin, so it's a 24RF08?
Is 8 pin, 24RF08 surrogate named P24S08.

- I risk to shock the board and myself?

Well, take care fo yourself

Ok, so if I buy that I only need to solder the cable to the eepron and to the serial to make it work?

giorno,

No need to solder anything. the interface has a serial connector and for eeprom you can use two probes (needles).

Ok! I'm probably going to buy this!

One more question: the address of paypal is my house, but during the day I'm in office so there is no chance to have the package sent to my work address?

victor · S.F. Boss Joined: 07 Mar 2004 Posts: 2581 Location: Staff

No chance, so you will have to take a cab.
