Sounds like you tried this, but it's worth a shot again. Remove the CMOS battery on the motherboard and let the laptop sit for an hour, then replace the battery with a new one.

If the only real issue is changing the time and date, you can do this in Windows and it will reset the BIOS clock, too, of course.

If the problem is that the time and date keep reseting, you either have a low CMOS battery or a short on the motherboard that is resetting it.

If all else fails, you might need to flash the BIOS from a floppy disk with the latest BIOS version for your machine to reset it and go from there.

PS: BIOS reset problems on laptops are sometimes due to power problems caused by battery packs going bad; check your battery pack, too, and see if it is working okay.

Good luck...

SOURCE: bios lock, ERROR CODE 0271

Hi,
Error code 0271 - Date and time error. Neither the date nor the time is set in the computer.
Run BIOS Setup Utility to reset the time and date
It sounds as though your computer has the wrong time in the CMOS. The CMOS (Complementary Metal-Oxide Semiconductors) is the chip that holds the basic startup information for the BIOS, system and its peripherals while the system is turned on and off.

If you can get into the BIOS check the date and time settings and make sure they are correct.

It may also be a case of the CMOS battery going out. When this happens your computer will tend to not keep the correct time. They are cheap and relatively easy to replace. Before buying a new batter your can try to take it out and let it sit for about 10 minutes or so to reset the CMOS and then go put the battery back in and go into the BIOS and reset the clock.

Hopefully taking the batter out or replacing it will get past your lock icon asking for the password. Just search for CMOS or BIOS default password for your brand of laptop.

SOURCE: forget BIOS Password (Laptop - IBM Thinkpad Lenovo R60)

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.

The cmos battery is possibly at a critical voltage. Replace the battery and set the clock etc.

The solution is different for each model, so if it's not on the list it probably won't work. IBM bios issues usually involve motherboard replacements or the epprom needs to be changed in order to access it. If the person who gave it to you, is there a chance you can get the information? you can try ebay, there are sellers who claim they can resolve the problem.

Testimonial: "Thanks John, but this machine looks to have come from a corporate excess, so there's no telling what th bios password is. When I found there was I bios password I contacted IBM & their solution was a replacement motherboard. Rushed out on eBay & purchased a mb for $50, but after doing more reading I figured I would give some of the other solutions a try before a complete swap of the mb... The original mb has a better ATI vid chip than the replacement, so I would rather keep that one in the machine "

Unlock password


It seems to have a password set for that hard disk. Try using another hard disk. If you have the same issue, then there is some sort of password set in the BIOS.

I accidently removed the cmos battery of ibm thinkpad t30. After that error 0271: time and date setting appear then power on password show up. I failed to get into bios to change the time and date setting...


Removing the BIOS battery will not remove the BIOS password because the password is stored on an EEPROM chip. The password can be retrieved with difficulty, it requires you to build an EEPROM chip reader. For instructions to remove this password, please click on this link :-

My laptop IBM 2652 is locked .A padlock appears at top left of screen.I would appreciate help in unlocking and returning it to factory settings.My user guide is lost.


The Thinkpad is locked with a Power On Password and its purpose is to prevent unauthorized access to the laptop..
This password is set from the BIOS configuration.
Removing the BIOS battery to set the BIOS back to the factory default will not remove the password because it is stored on an EEPROM chip on the motherboard.
There is a way to remove this password, but it requires electronic knowledge and soldering skills. Please click on this link and follow my instructions.

My IBM Thinkpad is not switching on?


The error message relates to the date and time setting in the BIOS, it has a wrong due to a flat BIOS battery. The needs to be replaced and the date and time corrected,
The padlock symbol indicates the laptop's BIOS has been set with a password and you cannot enter and change the BIOS settings without this password.

Replace the BIOS battery with a new one, then boot up and enter your BIOS password, then change the time & date, then save and exit.

ERROR 0271


Are you a computer whizz? (do you know a lot about computers like me?)

Could be the Cpu fan (Central Processing Unit)
That could be lethal to the laptop.
Just as well it's a IBM other wise . . .
As for the error it means the time and date are not set.
soloution: run the bios setup utillity to reset time and date.
