You'd have to purchase a new CMOS battery which is compatible with your laptop. After that, take apart your laptop and replace the battery. If you don't know how to do this, it's probably better that you have a shop assist as you can break other things.

Hi Dalibor
Error 0271 refers to the cmos battery being weak.
Try replacing the cmos battery.
Also make sure your date and time are correctly set!

I HAVE A IBM THINKPAD A22M LAPTOP WHEN IT BOOTS IT HAS A ERROR CODE OF 0271 CHECK DATE AND TIME SETTINGS AND BLANK SCREEN APPEARS AND A LOCK ICON APPEARS.... IT PROMPTS FOR A PASSWORD I DONT KNOW THE...


You will most likely have to remove the backup battery temporarily to allow the CMOS to clear the password lock.
The instructions for removing the CMOS battery are located here.
Be sure to disconnect the power cord and remove the standard battery when performing this work.
Be very careful to follow the directions exactly as shown.
You may have to leave the CMOS battery removed for a number of hours in order to clear the CMOS password.

I have 0271 error can get into bios but not able to change the date and time??


Hi,

The error means that you have to change the BIOS battery first before trying to change the date and time.
As far as i know with IBM's the CMOS (RTC) battery is located under one of the panels underneath the laptop and is usually covered with red, blue or yellow plastic with wires coming from it. Disconnect the battery and replace it

Once the CMOS battery is replaced you can set the date and time and no more error messages.


Regards.

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.
