Question Removing a Sony Vaio laptop bios password

I have removed Many bios passwords before and never had a problem. Yesterday I totaly stripped a new sony vaio 2.4 gig notebook to the guts and disconnected the battery for the CMOS, shorted the caps pressed the power a couple of times. Then left it for two hours. After reasembling the note book the laptop did give me post but went strait back to being locked. Any one know of a way to remove the password by either hardware or software or a combo of both the floppy nor cdrom picks up before the lock up.

You won't believe this. I had to hang up the phone with the sony tech shop in florida. They claim that there is no bios password that can be locked when you start the notebook. What a joke wander where they got certified at. But to answer your ? yes checked crack sites and sony sites.

Unhappy Vaio Laptop GRX 550, P4 1.6. Bios CMOS has CPU PERFORMANCE unaccessable

I was trying to overclocking my sony vaio laptop grx 550. It has a P4-m 1.60GHz. The problem is the Bios, Phoenix 4.0 reversion6.0, allows you to get into CMOS but when you try to enter into HARDWARE CPU PERFORMANCE, you can't. I mean the option is unaccessable. SO, i tried Softfsb but it did not work with laptop. I tried TwekBios and REMPASS ms-dos programs, but it still did not work. Pulled out CMOS battery over night and still CMOS option to the Hardware Performance was unaccessable. I used passwords. MS-DOS prompt. in safe mode, debug mode, safe mode with MS-Dos command
O 70 17

O 71 17

Q


STILL DID NOT WORK. I shorted the pins. looked for jumpers. I tried and read everything. SONY HAS GOT THE LAPTOP ON LOCKDOWN. I know that sony uses the same p4-m in different GRX models. they have set the multiper at 16 and the FSB at 100MHZ and depending on the model laptop, increased MHZ for a faster CPU. 1.8, 2.0, 2.2Ghz. Those bastards don't want anyone to find out that their 1.6Ghz CPU is capable of doing 2.2Ghz. Sony LOWER CLOCKED my CPU.

I am quite experianced with the sony vaio passwords having owned an FR130 and currently a R505EL (nice and Light I might Add). Anyway I recently got a free compaq Presario 1500 P4 and wanted to use it with the hard drive from my Sony because it was bigger and I work with music video's (Plus the Radeon 7500 w/32MB is a far shy better than an intel extreme on board.) Anyway I found that sony seems to hold a back of of the password settings on the hard drive (I had to start up a linux cd and reset every available password just to unlock the hard drive.) This leads me to assume that while the debug method is an easy norm to use in this case Sony has taken steps to prevent this. I can probably set you up with the CD I have that will boot and walk you through finding the password and reseting it. (Basically you owuld have to take it apart remove the battery then take the hard drive and reset the passwords located on it. While this is only an idea/theory of mine from experiance it seems to be the only way that it could retain the Password as it does. Hope this helps

I believe on some laptops there is a red button that you have to hold for 30 seconds. Am I wrong?

Angry SONY VAIO BIOS PASSWORD

OK, if you do not know your BIOS password, as what happened to me, (I have an sony vaio fx370 notebook), removing the cmos battery does nothing. The only way to unblock it is to go thru a lot of b.s. with sony. Basically, you have to call sony's 1-800 number and tell them what's up. They'll need to know your serial number along with a bunch of other info. Then they will ask you to fax them a copy of your receipt (if you don't have this then good luck!) On the receipt you'll have to put down whatever reference number they give you and then you'll have to wait 24 hours. After 24 hours, you can call back and they will give you a code to unblock the BIOS (so they say). What will really happen is that you'll have to send two more faxes and go thru this procedure again until they're ready to give you the code (it's as if they were gonna give you the code to launching a nuclear warhead). It really isn't fair since I never set the password to begin with, (contrary to popular belief) it was there from the start. I suggest asking for the password before even pulling out the credit card and demanding to know every detail of your new computer since you are investing a good chunk of money. This process has taken me about two months since I live abroad and at first they told me that removing the cmos should be enough, WRONG (and they know it)! Oh and by the way, if you buy the extra warantee at Best Buy, y'know the 3 year one, no matter what goes wrong it's covered, this is the one thing they DO NOT cover, they claim it has nothing to do with them and to go thru Sony. I wouldn't recommend the warantee since the techs at best buy are pretty useless anyway and I have more or less fixed my own problems and I'm no expert so it's pretty sad that I know more than they do. The only thing it's good for are the free batteries.

While I appreciate dinac4 posting that information, however the original post was back on 9/26/2002, and that member hasn't visited the forum since 10/17/2002....

Just FYI, you can usually search the internet for BIOS "backdoor" passwords, sometimes you can get lucky.
