Acer travelmate 2700 bios password and where is the CMOS battry on the mother board


Hi there,

your bios battery is soldered into the mainboard, its under the keyboard, next to the modem board and the bios chip itself.

In order to get to the battery you would first have to dissasemble the laptop, remove the keyboard, power buttons, and the top of the machine. You may also have to remove the display if its holding the top of the cover in place.

Removing the battery is no guarantee of reseting the password. You need to study the bios chip and find out which pins of it you need to short in order to reset its memory. In some cases the password might be stored on another chip.

Oh my laptop IBM R60 bios password and try by removing cmos battery but still please email me if u got the ideal


Removing the BIOS battery did not reset the BIOS password because the BIOS password is stored on an EEPROM chip. visit laptopmasterpassword.net

Changed out the motherboard reformatted a blank hardrive, No issues in the reformat.Installed drivers then updated the bios.Currently will only boot to bios briefly then shuts down.Tried resetting the bios...


Sounds like your BIOS update did not complete successfully. Head to the board manufacturers website and check if there is some way you can reload the BIOS and recover from this. Most boards now have dual bios which means that if one bios chip fails or an update fails, you can reload the stored BIOS through the other chip. If you are unable to recover from a failed BIOS update, you may need to purchase a replacement BIOS chip from the board manufacturer. You may even be able to reload the original BIOS onto the chip through your local PC repair store so give them a call and enquire..

Bios info on hard drive


The BIOS password is not stored in the hard drive.
Try Dell as the password first.
The BIOS password could be stored in the BIOS chip or an an EEPROM chip.
If the password is stored in the BIOS chip, you can restore the BIOS back to the default setting and remove the password by removing the BIOS battery for 1/2 + hour, insert the battery and go into the BIOS configuration to set the Date & Time.
If the password is stored on the EEPROM chip, there are no backdoor passwords available.

I need to clear my Bios Password for My IBM Thinkpad R52


OK, I posted this the other day, so for the benefit of those who missed it. "None" of these techniques will work on the R52, as it has a different chip. The above well intentioned solutions mentioned above will work with older models but not this machine as the bios chip has been changed. FYI

Re: power on + bios password


IBM uses a security chip on the motherboard that burns the password into it when a bios password is enabled. The only solution to getting around a bios password on an IBM is to replace the bios security chip or the motherboard. I've wrestled with this before, and believe me when I say it's a whole lot easier to replace the board. Do your best to remember!!!!!!!!
