Batteries are an expensive component of any portable device, even more so when they go bad. Some information on their care, handling, and replacement is important. Lets explore.
| CMOS Battery | CMOS is short for Complementary Metal-Oxide Semiconductor. CMOS is an on-board chip powered by a CMOS battery. The CMOS stores information such as the system time and system settings for your computer. |
| CMOS Battery Types | In Laptops, CMOS batteries are either button type mounted on the motherboard or plug wired. |
| Laptop CMOS Troubleshooting | A CMOS battery can be bad, but can be masked by a charged laptop battery. Disconnecting the laptop battery and allowing the system to sit un-powered for a short period of time after the system time / date has been set or verified is the key. Reconnect the battery, plug in system power, and if the system time is incorrect, the CMOS battery is bad. |
| Laptop Battery Tips | The identified link provides methods to care for and prolong the life of your battery. Power management is also addressed since it affects the performance of a battery. |
| Laptop Main Battery | The best way to protect your battery investment is to remove your battery and use external power whenever it is available. Constant charging will ruin a battery over time. |
| Laptop Power Supplies | Nothing lasts forever. Laptop won't turn on? Don't overlook the power supply. Swap it out or a DC Voltmeter you can check the output of the power supply. Without a voltmeter, a close inspection of the length of the cable will sometimes reveal the location of the problem. |
