The laptop fan is an integral part of any laptop. Laptops create an enormous amount of heat and excessive heat can cause components to fail. Combine that with the fact that laptops are getting smaller and more compact, and there is even less room for air to circulate. All of these factors make the laptop fan or fans an even more important component. Since the laptop fan is such an important part of a laptop, it is wise to know the signs of a failing laptop fan.

1. Overheating

Almost every laptop will heat up somewhat under heavy use. In most cases, you will hear the fan begin to spin faster and make more noise when this occurs. If your laptop begins to get excessively hot and the fan does not appear to be spinning faster, it may be failing.

2. Strange noises

If you hear strange whining or grinding noises, the source could be a failing laptop fan. In some case, the bearings of a fan wear out or lose their lubrication, and the result is a noisy or grinding fan. You should replace it immediately.

3. Laptop locking up

If your laptop freezes or locks up, especially when performing a processor-intensive task, it could mean a laptop fan failure. Excessive heat is one of the primary causes for computer freezes. If this problem persists, try replacing the laptop fan.

4. Fan keeps running

In some cases, the laptop fan may continue to run and run at full speed, even when the laptop is not hot enough to warrant it. This can also be a sign of a failing fan, as it is not responding to the laptop’s signal to lower the fan speed.

Replacing a laptop fan can be a simple job or a very complex one depending on your laptop model. Some fans are easy to access, while some require a lengthy disassembly process. You can check around in search engines for replacement instructions specific to your model to take some of the mystery out of replacing your laptop fan.

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 hard drive technology continues to improve. Faster hard drives with more capacity are arriving every year, and it can be difficult to know the difference between different standards. Here is a rundown of the different laptop hard drive technologies used today.

While most desktop hard drives are in the standard 3.5″ form factor, nearly all laptop hard drives use the 2.5″ form factor. While other standards are sometimes used in the smallest laptops, the vast majority of laptops use the 2.5″ hard drive standard.

There a few factors related to the speed of laptop hard drives. The first is the spin speed of the platters in the hard drive which store the data. The most common speed for laptop hard drives is 5400 rpm (revolutions per minute), but 4200 rpm and 7200 rpm drives are also common. Generally, the faster the rotation speed, the faster the access time for the hard drive, but a drive with a faster rotational speed will consume more power and will be more noisy during operation. These are reasons why many laptops have 5400 rpm drives instead of the faster 7200 rpm drives. The actual speed of the drive is usually measured in “access time” or data transfer rate. These ratings give buyers a comparison for which drive may perform better.

Most modern hard drives connect through either SATA or PATA (IDE) connections. PATA uses a large ribbon cable for connecting to the motherboard, and was the most common drive connection technology for many years. SATA, or Serial ATA, is a faster connection method, which also uses a smaller port and cable than PATA, making it ideal for the tight spaces of a laptop. SATA offers better access speeds than most other technologies.

A new laptop hard drive technology is emerging, called solid state, which uses flash memory instead of platters. The lack of moving parts results in lower power usage and often faster access times, but the cost of solid state drives is very expensive. As prices come down in the future, it is likely that solid state drives will become the most common technology for laptop hard drives.

Upgrading the RAM on a laptop computer is one of the cheapest, quickest, and easiest upgrades to dramatically improve its performance and boot time. Here we will look at the main benefits of upgrading RAM on a laptop computer.

1. Open more programs at once

Each program that a user opens resides in RAM. The more programs that are open at once, the more RAM that is required. When the system runs out of available RAM it begins using the hard drive for storing open programs. This can seriously degrade performance of the laptop, as reading and writing from the hard drive is much slower than reading and writing from RAM. Adding more RAM allows users to run more programs at once without slowing down performance.

2. Faster processing

Many high-end software programs, such as Photoshop and video-editing software, have to process large amounts of data while editing. This data is stored in RAM during processing. If the RAM is already full or nearly full, it will require more reading and writing, which results in slower processing. Adding more RAM to your laptop allows more of this data to be stored for processing, making the programs run faster.

3. Faster gaming

Most modern computer games process a lot of information. This makes them similar to the high-end software mentioned above. Many computer games require a minimum amount of RAM for good performance, but to get the best performance from any game, it is recommended that users exceed the minimum requirements.

RAM upgrades are some of the least expensive upgrades a user can make, and it is a very quick and simple upgrade. With the low cost of most RAM upgrades, it is often a good idea to install the maximum amount of RAM that a laptop can handle to ensure the most performance boost possible from the upgrade.
