    Found this on a forum:
    The reason for this little rant though has to do with Acer's "Customer-no-service" with regard to having a lockout due to a lost bios password. My Daughter thought she'd be funny and put a password on the boot-up sequence. She of course forgot what she used and I have spent close to 10 hours trying to figure out what the word is. I call Acer and ask them how to find the clear CMOS jumper and am told that there is no such thing but they'll gladly reset it if I send them the machine and spend $100.00 to have them "fix" it.

    I talked to every level of Acer support I could gain access to. I was told the same thing each time. I find this kind of thing to be COMPLETELY unacceptable. I'll never buy another Acer product and woudl not recommend the purchase of one of their machines to an enemy. The very idea that these arrogant schmucks not only want to charge me to do something so elementary is bad enough but they won't provide a schematic of the motherboard so that I can figure it out myelf.

    Fine, they want to treat me in that fashion I can guarantee that I will do everything in my power to make sure that NO-ONE I know will buy anything Acer or Acer related. This is going to cost them a sight more than a hundred bucks.
    Arrogant Corporate Greed - I HATE it!!

    if you are accessing the CMOS battery to nullify the BIOS password, don't bother - you're wasting your time.

    Acer BIOS passwords are contained in Flash RAM. Therefore removing the CMOS battery will only restore your laptop to factory settings while the boot password remains intact.

    On laptops, the password is usually stored in an eeprom on the motherboard,
    you need an eeprom programmer (electronic device) to retrieve it.



    you may need to contact an authorized Acer service center to resolvle this issue.

Cq56 reset bios password


You will have to remove the power cord, remove the batteryand remove the CMOS Battery that is located on the motherboard. On mostcomputers you will have to take the laptop apart to get to the cmosbattery. On some systems it looks like a silver nickel that you will needa small flat head screw driver to pop it out. On other systems it will beinside a vinyl covering and has a cable that plugs into the motherboard. Once you remove the CMOS Battery, let it sit for an hour or two then put itback in and put the laptop back together. Boot the machine and you'llprobably have to go into the Bios or System Setup because the system will haveforgotten the date, time and password.If the password is not reset then you might have to go and remove a Pin from the password jumper on the motherboard. I would consult the user manual and see how to do it.

I have laptop sony vgn-n530e i gave bios password but i forgate the password what showd i do


Hi Abid

BIOS PASSWORD CMOS/RTC BATTERY

The only way to solve this problem is to remember and enter the correct password.

On some laptops, it is possible to delete the BIOS Memory by temporarily disconnecting the CMOS/RTC Battery before reconnecting it and reassembling the laptop.

So no damage is done during disassembly and the correct component positions and cable connections are restored during reassembly, this is a job best done by an experienced repair technician.

See below for the location of a CMOS Battery in a typical laptop. The CMOS battery is the rounded, yellow, flattish object at the front centre of the image. While yellow is a common colour, the CMOS/RTC Battery can also be encased in blue, brown, black or green plastic.

On some models the CMOS/RTC Battery is accessible without disassembly, via the Wireless Card compartment underneath the laptop.

On other models, disconnecting and reconnecting the CMOS/RTC Battery is ineffective because nearby capacitors store the data if the Battery is removed and two contact points on the motherboard have to be bridged to dissipate the charge from the capacitors.

The Service/Disassembly Manual for your series of laptops can be downloaded in PDF format from here:

http://www.laptoprepair101.com/laptop/2008/01/07/service-manuals-for-sony-vaio-laptops-notebooks/

In this model, the rounded, flattish light blue object near the Wireless Card is likely to be the CMOS/RTC Battery.

I hope this helps.

I need to rest password in bios


Hi,
Removing the RTC battery and leaving it uninstalled for 5 or more minutes causes all passwords and CMOS settings to be cleared. BIOS password can be removed by temporarily disconnecting/ removing the RTC/ CMOS (Coin-cell) battery from the motherboard.
Disconnect the coin-cell battery from the system board and it will reset the BIOS to its default setting and the password would be gone.
Please Refer to Page 29, 106 & 79 of the REPAIR MANUAL IBM T40 for Battery removal, keyboard removal and RTC battery removal instructions.
The Backup Battery (RTC, CMOS) is located under the keyboard. So you have to remove the keyboard to access the battery. The above Manual from IBM shows the exact method/ instructions and pictures for laptop dis-assembly for the purpose.
If you are comfortable with working inside such electronics, you can't do it yourself, or else you may seek help from local laptop service professional.


Hope it helps! Good Luck! Thanks for using Fixya!

Remove/disconnect the RTC-battery which is used for buffering the BIOS.

- Unplug AC, take out the main battery;
- take out the RTC-battery for app. half an hour (the period of 5 min as specified in the docs normally is not long enough);
- reconnect RTC-battery;
- plug in the AC adapter (battery still removed).

is the file who can help you.
