sony PCG-GR370 Bios Lockout

Sony Vaio pcg-gr370 notebook computer

Specs: Windows XP
Ok so heres the dillema. I have an old sony PCG-GR370. I am locked out of the bios because the administrator before me set a pw on it. I have tried removing the keyboard and unplugging the jumpers that are connected to the battery. The battery is soldered onto the mobo so physically removing it doesn't sound wise. When I started the comp after removing the jumpers for 24 hrs it stated that CMOS was reset to factory default but it is still asking me for the f'ing pw. I am out of ideas.

Sony wont help without a receipt but honestly who has a receipt from 2000?

I cant run any CMOS killing software as as soon as the comptuer boots it requests a pw so I wont be able to get it to boot from a cd drive.

Any Input or ideas that i havent thought of would be excellent.

We have no way of confirming that you should have the rights to remove passwords on this computer.
Do you have a legitimate reason for why you can't remember a password you had to use every time you used the computer ? ?

If you have never known the password, you wanting to know about how to remove it is what a thief or someone who knowingly or unknowingly bought a stolen laptop would want to know.

Case is important regarding passwords - whether characters are upper or lower case.

Modern laptops are well protected from you removing passwords, for obvious security reasons.

Removing or unplugging the cmos battery will not get rid of passwords on newer laptops - the info about the specific passwords is NOT in the Cmos - therefore, "Cmos killing" programs are useless for newer laptops - it would have to be more than about ten years old or older in order for that to even be possible. The specific passwords info and the info about whether there is one is stored on a separate chip on the mboard that cannot have it's data contents erased by removing the power to it. If access to the hard drive is passworded, the info about that is stored on both that separate chip and on the hard drive in a data area that is not accessible when you use any normal progam.

"Sony wont help without a receipt but honestly who has a receipt from 2000?"

It sounds like you do have the separate chip on the mboard that cannot have it's data contents erased by removing the power to it, otherwise Sony could tell you how to remove it, and/or if you could find a service manual for it, it would probably tell you how to remove the passwords in that.

Did you register the laptop with Sony? If you did, that may be sufficient proof that you're the legitimate owner. Most brand names won't help you regarding removing passwords if you aren't the original owner.

If you don't have a hard drive access password enabled, this model is old enough you may be able to buy a used mboard cheaply for this model on the web that has no passwords enabled.

If you DO have a hard drive access password enabled, replacing the mboard with one that has no passwords will allow you to access the bios or the system, but the hard drive will still be "locked".

because the the computer is over 10 years old and our IT admin at the time put a pw on it.... as he no longer works here our biz is locked out of our own computer. The hard drive data is not important. We need the laptop as a laptop not for the data.

You could try finding out if the former administrator can still be contacted via info your company still has, or whether that can be determined - if you can contact the person, he or she may be able to help you solve your problem.


The Owner's or User's manual for the model or model series may tell you whether or not bios or system access or hard drive access passwords can be removed, but often they don't.

Sony doesn't make Service manuals available on their web sites, that I know of, at least not that you can download free like you can for most HP or Compaq or Dell laptops, but some Sony ones can be found on the web, for free, or for cheap.
I found one for a Sony FX-120 laptop for a friend.
By the way, when I was searching for that, I found the Sony bios shows you the actual model - using the model on the label on the outside of it may yield you little or no info on the Sony web site(s) - since you can't access the bios, you may need to search using the model or product number on the label on the web in order to find mentions of the actual model.

Look on the web for a service manual for the model. If it's old enough that it doesn't have that extra chip on the mboard that can't have it's data contents erased by removing the power to it, there are probably instructions in that manual that tell you how to go about removing the password(s).

If that doesn't help, there's a good chance you can find a used mboard for it on the web that has no passwords enabled for a reasonable price.

Other than that, there may be other ways of revealing or removing or changing the passwords, but it's against the rules of this site to reveal those ways.

However, I have no objection to someone who answers here who comes across this Topic sending you a PM - Personal Message - with that info in it - that does not appear in the pages on this site, and the person, or you, can delete all their PMs after they have been sent or received.

the mobo does have a chip on it storing the saved info. I talked to sony and they want 50 bucks since its out of warranty plus proof of purchase plus any additional fees that may be incurred. The computer is a pos and i am out of ideas. I think well try and get ahold of our previous admin, thats the best bet.
