Thinkpad is a brand of portable laptops originally designed and manufactured by IBM. Thinkpad batteries are based on the latest technology, which utilizes the CMOS system. CMOS or Complementary Metal Oxide Semiconductor is a data storage utility. It is used to preserve system settings, such as time, date, boot order and the hard drive type, even when the laptop is switched off.

Thinkpad Batteries: Replacing the Backup Battery

Thinkpad batteries and its backup utility are easily replaceable. You can replace the battery backup on your own using the following information:

1. Determine the kind of CMOS battery required as a replacement for the used one. You can purchase a compatible battery from online retail stores at reduced prices.

2. Switch off the Thinkpad and turn it upside down. Touch some metallic object to remove the static charge from your body.

3. Slide the release button of the main battery to the 'unlock' position. Withdraw the primary battery. The CMOS battery is generally positioned in the memory compartment. Remove the memory cover to locate the CMOS assembly. (The CMOS battery will be enclosed in a yellow rubber-like material, within a black plastic guide).

4. Unscrew the plastic guide and lift the rear end of the CMOS assembly.

5. Pull the CMOS assembly out of the Thinkpad and keep it parallel to the laptop case. Plug the battery connector to an electrical outlet. Push down on the backside of the plastic guide and then replace the screw.

6. Replace the main battery and plug in the laptop. Restart your system and enter BIOS by pressing F1 or F3. Reset the time and date in your laptop and save the settings.

Thinkpad Batteries: Ensuring a Long Life

There are several ways to ensure longer life for Thinkpad batteries:

1. Put the screen contrast and other features on their lowest settings. Some laptops even have the option of changing the CPU and cooling system properties. Utilize these properties.

2. Add RAM. A larger RAM allows you to process more information in the system without using the virtual memory. Virtual memory uses the hard drive, leading to lesser power-efficiency.

3. Defrag the system often.

4. Shut down unused or inessential programs running on the system.

5. Do not plug your laptop to power whenever you are working on it.
