Problem of my sony vaio grz610 is on bios..when you open it, it has password already.what will i do?
Thanks for the clarification! How old is your laptop? On older models you can sometimes pull the power/battery and then take out the CMOS battery (hopefully not soldered) for a good while, then re-try. Of course this entails taking apart the laptop. On newer models, especially Sony, as the previous poster mentioned the BIOS PW is stored in EEPROM (non-volatile memory) so the battery method no longer works. There are some other options that I've seen work, such as:
--Backdoor/Manufacturer BIOS password. Depending on the BIOS (Award, Megatrend, AMI, Biostar, Soyo, etc.) there is sometimes a mnfr. PW used for maintenance/repair. There are lists around, but I've never used that on a Sony laptop.
--I've seen a few keys work while at the password prompt that have bypassed it, but obviously this would be different for different models/manufacturers. This was also on older models. A few that I remember are pressing:
--Re-flashing the BIOS
--Shorting the jumpers/pins. As a last resort I have cleared the BIOS by shorting 2 pins together or even the two CMOS battery points. NOT FOR AMATEURS!!! To accomplish this successfully, you really need to have the motherboard schematics and to know exactly what pins you are looking for. This isn't for the faint of heart; really only as a last resort if it is the only way you might be able to access your laptop, as you can run the risk of frying the laptop.
-There are a number of software programs that can help depending on your situation. If, however, it IS a BIOS password (not a HD password) that is stored on an EEPROM chip, I have not personally used or seen one that has worked.
Otherwise, you pretty much have to bite the bullet, call the manufacturer, and pay them their blood money to replace/re-flash your chip. For this you will usually need to provide proof of ownership and some cash, unless it is still under warranty.
I'm sorry, I wish I had an easy answer for you, but BIOS passwords aren't made to be easy to bypass. I hope I helped with at least some additional information. Good Luck and let me know if you have any further info or developments!
