A CMOS battery typically lasts between four and seven years in a computer before it begins to die, however system trauma or a defective battery can, rarely, cause a battery to malfunction well before its time. You’ll know when your CMOS battery has gone bad when you see messages that mention something like “CMOS checksum error” or a similarly described problem. Oftentimes, you will see this error reporting infrequently on boot up, indicating that the battery is dying but not yet completely gone. This is the ideal time to replace the battery. However, if you get the error every time you boot, the battery is likely completely dead, and you may have lost your BIOS settings along with some other system information.

Before removing a CMOS battery for replacement, be sure to enter set up mode on your computer, and copy down all of the settings in your BIOS menus. This is what is stored on that battery, and when you remove that battery, that data will be erased. After replacing with a new battery however, you can go into BIOS and restore those settings from your copy. Also, some programs will back up your BIOS settings to an external disk of some sort, allowing you to reload them at any time.

In laptops, CMOS batteries are typically found beneath the keyboard. This can pose a challenge, as the keyboard on a laptop can be difficult and delicate to remove. It is also important to note that on some models, the CMOS battery is actually soldered to the mother board, in which case you will not be able to remove the battery without professional assistance, either through a repair company or the manufacturer. In laptops with removable batteries, there will typically be a tension clip holding it in place. Simply open the clip, remove the battery, and replace it with a new one. Make sure however that the new battery matches the replaced battery. Consult your computer’s hardware manual or a local or online retailer to be sure you get a direct replacement that will function with your mother board.

Laptop keyboards are generally dictated by the available space. For example, a typical 15.4″ laptop or notebook will often feature the standard keyboard layout minus the number pad. In most cases, the number pad is overlaid on top of other keys and utilized by pressing the num lock key or pressing the fn (function) key along with the desired numbers. This is a good solution for the average user, who won’t often need the number pad. Users who frequently work in Excel or other number-heavy applications, however, may find this limiting. Larger laptops and notebooks, at 17″ or above, often include a basic number pad, and may be a better choice for those who require one.

Because of the limited space and the need to add more functionality, most laptops also incorporate quick-keys and media keys into the design. Quick-keys are those that open a program or perform a specific function, such as opening and email program or opening a web browser. Media keys provide quick access to functions such as play, pause, and volume which can usually control a variety of programs, depending on user preference.

The smallest laptops and notebooks, often referred to as netbooks, have the most limited space of all. In some cases, netbooks can feature a 9″ or smaller screen, which leaves very little space for a keyboard. This requires smaller more closely spaced keys which are not ideal for touch typists, but are usable enough for mobile computing.

As laptops and notebooks evolve, we are likely to see many new innovations in laptop keyboard designs to maximize usability and utilize every bit of space available. You can rest assured, however, that the standard QWERTY layout is not going away any time soon.
