When you begin receiving errors that your system doesn’t match the configuration, or you getting a warning in the BIOS that your battery is dead, you most likely need to replace your CMOS battery. The CMOS battery provides the motherboard just enough power to retain the CMOS settings for your laptop. If this battery dies, your machine will likely still function, but some of the stored parameters such as time and date will not be correct and any BIOS settings that are stored in CMOS would be lost also each time the computer is powered down.

Replacing the CMOS battery is not usually difficult, but the procedure can vary greatly depending on the laptop’s model. The easiest way to find specific instructions is to do an internet search for the term “service manual” and your laptop’s manufacturer and model. Often, you can find a PDF version of the service manual for your specific laptop, which will give you detailed instructions for repairs and upgrades.

Most CMOS batteries are located under the keyboard, which can require removing the keyboard. Other common locations are under the touchpad, behind the battery, and some are accessible from the bottom of the machine via a small plastic cover. While it is difficult to give detailed instructions for the multitude of laptop models on the market, here are a few guidelines for replacing the laptop CMOS battery.

1. Wear an anti-static wrist strap when disassembling any laptop. This reduces the risk of damage from static electricity.
2. Remove the battery completely and disconnect all power cables to avoid the risk of electric shock or damage to the laptop or notebook.
3. Remove the Keyboard or associated cover to expose the CMOS Battery and remove. Carefully keep track of all screws removed. Group and label them to avoid confusion when reassembling.
4. When prying ribbon cables or plastic parts apart, be gentle to avoid damaging sensitive components.

With some preparation and planning, replacing the CMOS battery should be possible for most users. If you cannot find a suitable service manual or you don’t feel confident in your abilities, it is a good idea to take it to a repair center.

Laptop batteries do not last forever. Even under the best conditions, a laptop battery loses some of its capacity over time, and eventually will need to be replaced. In addition, a number of problems such as over-voltage or under-voltage can cause a battery to fail prematurely. Here are most common signs that it may be time to replace your laptop battery.

If your battery is giving less than 50% of the battery life it was giving when it was new, it is probably time for a new battery. All batteries lose their capacity over time due to corrosion within the battery. Once this begins to affect capacity to a large degree, the battery should be replaced.

Windows and most operating systems will give an indication if there is a problem with the battery, assuming the manufacturer has designed the laptop to communicate with the battery. In many cases, you will get a warning message telling you to check or replace the battery.

Many batteries are equipped with one or more lights that indicate when it is charging and when it is finished charging. Some also give an indication of problems with these lights. Check your manual if your battery is flashing or blinking in a way you don’t recognize.

In some cases, even when the operating system or the battery doesn’t indicate a problem, the laptop will not run on battery power alone, but only when the AC adapter is connected. In this case, it is a good idea to replace the battery.

One of the surest ways to know if a battery is functioning correctly is to use battery health monitoring software. This will give an indication of the capacity left in the battery, and an indication of the battery’s overall health.

If you suspect your laptop’s battery is failing it is often a good idea to purchase a replacement. You can find an OEM or a compatible replacement by visiting an online parts store. Cases of a faulty battery causing damage to a laptop are very rare, but it is hardly worth the risk for a relatively inexpensive replacement.

While laptop battery technology is constantly improving, offering longer battery life and lighter laptops, all laptop batteries still have a limited life. Here we will look at some signs that it is time to replace your laptop battery.

Reduced Battery Life

The most common problem for laptop batteries is reduced battery life. It is an inevitable fact that laptop batteries eventually lose some of their capacity, and therefore, the amount of time they can supply power on a single charge. Even a battery that is used correctly will eventually begin to lose some of its capacity. The typical life for a lithium ion battery is around 2 years.

Very Short Battery Life

A typical laptop battery loses a certain amount of capacity over a period of time. If your laptop battery has lost a significant amount of capacity in a short period of time, it may be damaged, or may be exhibiting the “memory effect” that causes some older battery technologies to lose a large amount of capacity. Unfortunately, this often requires a new battery.

Battery Won’t Charge

If a laptop battery won’t charge or charges much slower than normal, it is most likely damaged. This damage can be caused be extreme heat or other problems, but a battery that won’t charge usually needs to be replaced. If the laptop won’t run on either battery power or its AC adapter, however, the problem is most likely not the battery, but the AC adapter or power supply.

If you suspect your laptop battery needs to be replaced, it may be helpful to use a battery diagnostic tool to check the status of your battery. Do an internet search for the term battery diagnostic tool. These tools can give you information on the life, capacity, and health of your battery. If your battery needs replacing, it is recommended that you replace it as soon as possible to avoid damaging your laptop or other safety risks posed by a bad battery. You can check with an online parts locator, to determine your appropriate battery replacement.

If your laptop has a dead or malfunctioning battery you may have found that a replacement battery is expensive. If you use your laptop at home and have it plugged into a wall outlet most of the time, you may have wondered whether the laptop will function without a battery, and whether or not it is safe to operate it without one. This article will address some of these questions.

Most laptops are able to run without a battery. The simplest way to find out if your laptop will run without a battery is to try running it without one. Before you do, however, take a few simple precautions. First, save any open documents or files and shut down the computer completely. Second, make sure the AC adapter is connected and the laptop is receiving AC power. Windows will often show a power indicator in the taskbar in the lower right of the screen that shows the battery status and whether the AC adapter is connected.

Now you can shut down the laptop completely and remove the battery. Make sure the AC adapter is firmly connected and plugged into the wall and press the power button on your laptop. If the laptop starts up and seems to run normally, it will most likely operate without a battery.

There are a few concerns that you should be aware of before you operate your laptop without a battery in the long term, however. Some laptops, such as the MacBook Pro, have been shown to have degraded performance when running only on AC power without a battery. You could test this by running performance tests with and without the battery to see if your system is affected. The other concern is that AC power cables are meant to be removed from the laptop easily, and could get knocked out by accident. With no battery to keep the machine running, it will shut down suddenly, possibly losing your open documents and other important information.

You are unlikely to encounter major problems running your laptop without a battery, strictly on AC power. However, consider buying a replacement battery for emergencies or for the extra peace of mind of not having to worry about a disconnected power cable. Compatible batteries are available for most laptops for a fraction of the cost of OEM batteries and still provide the same charge.

There are many factors that affect battery life. Some, users have control over, and some they do not. Let us look at a few of the main factors that affect laptop battery life.

Hardware

Laptops have many components, and though they are all designed to use as little power as possible, some still require a large amount of power. The component that requires the most power is the display monitor, followed by the hard drive. This is the reason power settings center around dimming and turning off the display and shutting down the hard drive when not in use.

Temperature

Another major factor that affects laptop battery life is temperature. Lithium-ion batteries, the most common type of laptop battery, are susceptible to problems caused by extreme heat. Excess heat can cause the batteries to malfunction, have a shorter battery life, lose capacity, or in the most extreme cases, catch fire or explode. Leaving a laptop in a hot car or keeping it in an area with poor ventilation, therefore, is not recommended.

Laptop Design

When it comes to laptop battery life, one of the largest factors to affect it is the laptop design itself. For example, laptops and notebooks designed for high-end video editing or other processor-intensive tasks will use more battery power than small netbooks designed for web surfing and email. Laptops that consume the most power will need to recharge the battery more often, shortening its laptop battery life. Also, the physical design of the laptop can affect laptop battery life. Laptops that are designed to stay cooler when running will also keep the battery cooler, and as mentioned above, heat is the enemy of a notebook or laptop battery.

Age

Lastly, all laptop batteries have a limited life. Even a battery that sits on the shelf will begin to degrade. Having to replace a laptop battery at some point is inevitable, but make sure to recycle any old laptop batteries, and keep them from ending up in a landfill, where they can leak toxic chemicals into the air or water.

Every laptop user at one time or another has run out of battery power, and it seems that you always run out of battery power at the worst possible moment. Getting more out of your battery starts with knowing which components drain the battery the most, so that you can minimize their impact on your overall battery life. Here is a list of the 5 biggest battery drainers for laptops.

The LCD Display

The LCD display is by far the biggest battery drainer in a laptop. In some models it can account for more than 50% of the power used. To combat this, sleep the display as often as possible. Turn down the screen brightness whenever possible as well.

The Chipset

The chipset includes the motherboard and graphics processor. Models that have a dedicated graphics processor will require more battery power. Sleeping the display or putting the machine in standby will help to minimize the need for chipset power.

External Devices

External devices such as USB hard drive, MP3 players, thumb drives, and other devices can use up a lot of battery power, especially those are powered or charged from the USB port. Unplug any unnecessary devices and accessories to save battery power.

The Processor

The processor generally uses around 10% of the battery power in use, though it requires more during heavy processing. Close unnecessary programs and background processes to reduce the load on the processor to prolong battery life.

The Hard Drive

The hard drive tends to use about 5% of the battery power in use, but uses more when the system is reading to and writing from the drive heavily. As with the processor, closing unnecessary programs and background processes will help, as well as avoiding programs that frequently write to the drive.

These guidelines give you an idea of the laptop components that use up the majority of your battery life. Following these guidelines and utilizing the laptop’s power management features should help you prolong the battery life of your machine.

The laptop battery is an integral part of a notebook computer, as it provides the portable power needed to use your laptop on the go. Unfortunately, laptop batteries can experience a number of issues, and even in the best case, a laptop battery only has a limited life before it will need to be replaced. Let’s take a look at the 5 most common laptop battery problems.

1. Age or loss of capacity

Laptop batteries have a capacity, usually measured in milliampere-hours or mAh. Over time, the batteries capacity will shrink, as it loses the ability to fully charge all of its cells. Laptop Batteries that have lost a significant amount of capacity will need to be replaced.

2. Heat or swelling of the battery

If a notebook battery becomes too hot, it can begin to swell and expand. This can be caused by poor ventilation or an overheating computer. It is important to replace a swollen laptop battery, as it can be very dangerous, and can cause damage to the laptop or injury to the user.

3. Discharge

If a notebook battery sits unused for a long period of time, it can be difficult to recharge it. This affects older batteries more than modern batteries. If the laptop battery cannot be recharged, it will need to be replaced.

4. Memory Effect

Older laptop batteries sometimes experienced what is known as “memory effect”. Notebook Batteries that were not discharged often would sometimes become unable to use some of the cells, reducing capacity significantly. If you have an older battery, especially a Ni-Cad laptop battery, be sure to discharge it completely at least once a month, to avoid the memory effect.

5. Manufacturing defects

Many manufacturers have had to recall laptop batteries in recent years due to manufacturing defects that caused them to malfunction. Sony, Toshiba, Dell, and Apple were all affected. If you believe your notebook battery has malfunctioned, or is prematurely losing capacity, contact the manufacturer to see if a recall has been issued for your model.

Over the past several years, lithium-ion batteries have been the preferred technology, not just for laptop batteries, but also for a number of electronic devices such as cell phones and MP3 players. Some of the main reasons for their popularity are that they are inexpensive to manufacture and that they don’t exhibit many of the issues that plague older technologies, such as the “memory effect” which can cause a dramatic decrease in capacity. Lithium-ion batteries can still have problems, however. Here, we will explore a few of the main issues that can affect lithium-ion batteries.

Decreased Capacity

The main problem with lithium-ion batteries is that they tend to lose some of their capacity over time. This is caused by deposits that form inside the electrolyte of the battery, which eventually inhibits the transport of ions. Eventually the battery loses a large amount of its capacity and needs to be repaired or replaced.

Overheating

Lithium-ion batteries tend to heat up when being charged or discharged. Generally, this is not enough heat to cause any concern, but if the battery malfunctions, it may cause a large amount of heat. In extreme cases, batteries may even bulge or catch fire, though these cases are very rare. Li-ion batteries have many safety features to protect against these kinds of malfunctions.

Not Charging When Plugged In

In some cases, a laptop battery will not register as charging even when the laptop is plugged in. Check to make sure the battery is correctly inserted and that the AC adapter is connected securely to the laptop and the wall outlet. In most cases, this problem is caused by a bad AC adapter or a defective DC jack on the laptop instead of the battery itself.

Despite the few issues mentioned above, lithium-ion batteries tend to be very robust and reliable. Lithium-ion will continue to be the battery of choice for quite a few more years, even as it is slowly replaced by newer technologies.

All laptop parts have the potential to fail at one point or another. The most likely components to fail are often those with a number of moving parts, as wear and tear will eventually take their toll. A laptop AC adapter failure, however, is common. Since the adapter has no moving parts, it is much less likely to encounter mechanical problems, but failures can still occur.

When troubleshooting a laptop AC adapter, there are a few steps that can help rule out other causes and narrow down the issue that is causing the problem.

1. Ensure you have the correct AC adapter

Ensure that you have the correct adapter for your laptop. Especially in a house or office environment with multiple laptops, it can be easy to grab the wrong one by mistake. Most laptop AC adapters are incompatible with other laptop models. In many cases, the tip will not fit into an incompatible laptop, but this is not always true.

2. Check for damage

If your AC adapter seems to be failing, check for signs of visible damage. Inspect the tip which inserts into the laptop, as well as the entire cord, looking for extreme kinks or frayed wires. Also check the transformer or “brick” for any signs of wear, such as cracks or bulging. If any of these signs are present, you should replace the AC adapter immediately to avoid any risk of electrical shock or damage to the laptop.

3. Try another adapter

If you have a second adapter or can borrow a compatible adapter from someone with the same model of laptop, you can rule out the possibility that the problem is caused by another component. Often, problems with the other internal system components can cause charging issues and other symptoms that aren’t caused by the AC adapter itself.

If you have tried these steps and believe your laptop AC adapter needs to be replaced, make sure you find a compatible replacement for your model. Many online retailers offer a parts locator tool for finding replacement parts specific to your laptop model. Many reputable sellers also offer customer support by phone to help you find a suitable replacement.
