This is a common problem with the T20 series Thinkpad. The problem is with the power management chip. Unfortunately, you will have to replace the motherboard to fix it. Since these are a bit on the older side, you can get a motherboard off Ebay at a reasonable price.

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.

SOURCE: IBM ThinkPad T20 - 0190 Critical Low Battery - Will not boot

Hi,
When you boot, do the lights come on briefly, then go off? If so, the memory may be to blame.
Also, try booting without the battery at all.
Let me know.
Thanks,

Getting a CMOS checksum bad error when starting my Acer M5640 Desktop with Windows 7 Thanks Daniel


Solutions to CMOS Checksum Bad Error

The CMOS Checksum Bad Error can be fixed easily by following the listed steps carefully.

CMOS Battery may not be functioning properly

If you suspect that your CMOS battery is not functioning properly, you can easily change it. Before changing your battery, reboot your computer to make sure that the error still exists. If it does, go into your CMOS and write down all of the settings. If all the settings are lost, you can usually retrieve them from your computer manufacturer. Now locate the battery and remove it, you might need to consult your computer's manual or technical support to remove your battery (the battery a flat, shiny silver colored and coin-shaped). Take down the CMOS battery's information such as volt, size, etc. Once you have your new battery, you can replace it and reenter your CMOS settings. If your battery was the cause of the CMOS Checksum Bad Error, you should have solved the problem.

Your BIOS may have been updated

If your BIOS have been updated recently, your CMOS settings may have reset. Make sure that the values entered in the BIOS are correct or simply reset them to the default settings. If you believe that a virus has updated your BIOS settings, run a virus scan and make sure that the BIOS settings are back to the default.

The Computer may not have been shut down properly

Sometimes when running MS Windows, if you shut down your computer without first properly shutting down your operating system, it will corrupt the CMOS settings causing the CMOS Checksum Bad Error. You can easily avoid this error by making sure that you completely shut down your computer properly before turning off the main power. Usually this entails going into the Start Menu, clicking on Turn Off Computer/ Shut Down. If improper shutdown was the cause of the error, you may have solved the issue.

Tip

How to verify that the CMOS battery needs to replace


<p>The CMOS battery is named after the Complementary Metal Oxide Semiconductor power. The CMOS has the current date and time functions for desktop and laptop computers. It allows the computer to automatically adjust the time, even on computers that are disconnected for long time. When a computer no longer has the date and time and forget it on every boot, the CMOS battery probably needs replacing. Some computers have messages when the battery is weak, while others just lose the current date and time after each shutdown.<br /> <p>Time & Date Errors<span> </span><br /> <p><span> </span><br /> <p>1. Turn on the computer. Look in the task bar at the bottom right. Make sure the date and time is set correctly. Double-click the time and click the up or down arrow to switch to the correct time. Click on the arrow next to month to change the month. Click "OK" when finished.<br /> <p><br /> <p>2. Turn off the computer. Wait 3 to 5 minutes and start the machine.<br /> <p><br /> <p>3. Look on the taskbar to see if time was lost and said a strange date January 1, 2000. Replace the CMOS battery, if this is the case.<br /> <p><br /> <p>CMOS Error Message<br /> <p>1. Look for error messages like "CMOS checksum error", "CMOS Read Error" or "CMOS battery failure" when you start your computer. These errors are caused in the machines shut down for several months or when the CMOS must be replaced.<br /> <p><br /> <p>2. Let the computer on for 24 hours. Restart the computer and find the error.<br /> <p><br /> <p>3. Change the CMOS as the return error.<br />

My lenovo 3000 G410 when ia tr to start it nothing happens???? help


Hi,

Is there power when you turn the system On?

In your case it is very difficult to find out which is causing the system not to power, this can be multiple devices on your ssytem.

trying to eliminate one device after another try following the steps below:

>remove the Battery from the system, unhook the adaptor as well then Press and Hold down the power button for 7-10 seconds to drain any power on your motherboard.

>after power draining the system connect the adaptor to your laptop, do not insert the battery yet, Power the system without the battery, if the system turns on leave it turned on for about a minute then shut it down normally.

>insert the battery to the laptop turn the system on if this turns on without any error then your concern is probably ok and fixed.

>but if the system still does not power up having the battery connected to the machine a device on your system can or maybe damaged either the Battery or the Motherboard having an issue with the battery conencted to the machine...

if your system is in warranty call Lenovo and have it sent to teh service center for proper checking and repairs.

My lenovo 3000 Y 500 7761 47Q is shutting down abruptly. Hi Team, I am using Lenovo Laptop since Aug 2007. Around an year back April 2009 my laptops adapter was short circuited and I purchased a new one...


Have you tried a different battery. When the system is on, please check your battery settings to see if it is fully charged. Go to Start/Control Panel/Power Options and the very last tab.

This should tell you how much battery power is in. If it is very low it means that your battery is not getting a full charge and this could be the cause of your problem.

Let me know how it goes. Don't forget to vote for me.

Booting problem


There are usually three main reasons that a CMOS Checksum Bad Error has occurred. They include:
  • CMOS Battery may not be functioning properly. The battery life may have expired.
  • Your BIOS may have been updated (either by user or possibly a virus)
  • The computer may not have been shut down properly e.g. shutting off the computer's main power without first shutting down the computer (MS Windows requires you to shut down your computer before shutting off the power).

Ibm think pad r32 0196 critical low-battery error will boot up then turns it self of


Fail safe in the battery has engaged. See if the computer will start without the battery, using just the power supply. If you can get it started then put the battery in and see if it will charge or reset the fail safe. Give it about an hour, then shut it completely down and restart it with the battery in. If it won't start at this point, then you will need a new battery. Also change the CMOS battery inside the computer






Change the CMOS battery

This sounds like a fail safe in the battery has engaged. See if the machine will start without the battery, on the supply only. If you can get it started then put the battery in and see if it will charge or reset the fail safe. Give it about an hour, then shut it completely down and restart it with the battery in. If it won't start at this point, then you will need a new battery.
