How To Avoid Laptop Battery Overheat

One of the most common issues with laptop batteries is overheating. Not that the batteries are designed poorly or improperly but due to, in most cases, user wear and tear. While the laptop is using the AC adapter for power the battery acts as a back up in case of a loss of power or accidental unplugging. During this AC power use the battery becomes hotter than it would if being used independently. To lessen the chances of this overheating, which leads to a shorter life expectancy of the battery, keep the AC power adapter plugged in only if you need to charge the battery while using the device.
If the battery is consistently hot to the touch, remove it and allow it to cool down first making sure it is close to room temperature before reinserting it. Should the battery continue to overheat or get too hot it will probably need to be replaced. Always replace a defective battery as soon as possible as it could cause irreparable damage to the laptop in question. In addition to overheating failure to charge or hold a charge is another very common issue with laptop batteries.

First check to see if the AC adapter is securely plugged into the device; the tightness of the connection will vary form laptop to laptop but it should be held in place well. To check for a good connection look for the battery charging LED if one is present on your laptop. If it is not on wiggle the cord to see if the connection makes and breaks contact. If you notice a flickering LED light then the solution is a new adapter which is far better than needed to purchase a new battery or a new DC power jack which can be repaired by a common user with a little instruction and help.

Types of Computer Viruses

A computer virus is referred to as a computer program that can copy itself and infect a computer. “Virus” is commonly used to indicate other types of malware, adware, and spyware programs that do not have the reproductive ability.

A real computer virus can only spread from one computer to another when its host is taken to the target computer. The virus is contracted in some form of executable code.

Below are a few examples of computer viruses:

Direct Action Viruses
Replicates and takes action when it is executed. When a specific condition is met, the virus will go into action and infect files in the directory or folder that it is in and in directories that are specified in the AUTOEXEC.BAT file PATH. This batch file is always located in the root directory of the hard disk and carries out certain operations when the computer is booted.

Resident Viruses
This type of virus is a permanent which dwells in the RAM memory. From there it can overcome and interrupt all of the operations executed by the system: corrupting files and programs that are opened, closed, copied, renamed etc.

Examples include: Randex, CMJ, Meve, and MrKlunky.

Trojans or Trojan Horses
Another unsavory breed of malicious code are Trojans or Trojan horses, which unlike viruses do not reproduce by infecting other files, nor do they self-replicate like worms.

Boot Virus
This type of virus affects the boot sector of a floppy or hard disk. This is a crucial part of a disk, in which information on the disk itself is stored together with a program that makes it possible to boot (start) the computer from the disk.

The best way of avoiding boot viruses is to ensure that floppy disks are write-protected and never start your computer with an unknown floppy disk in the disk drive.

Examples of boot viruses include: Polyboot.B, AntiEXE.

Macro Virus
Macro viruses infect files that are created using certain applications or programs that contain macros. These mini-programs make it possible to automate series of operations so that they are performed as a single action, thereby saving the user from having to carry them out one by one.

Examples of macro viruses: Relax, Melissa.A, Bablas, O97M/Y2K.

Directory Virus
Directory viruses change the paths that indicate the location of a file. By executing a program (file with the extension .EXE or .COM) which has been infected by a virus, you are unknowingly running the virus program, while the original file and program have been previously moved by the virus.

Once infected it becomes impossible to locate the original files.

Laptop Stands and Docking Stations, What is the Difference?

By Anne Clarke

If you are a laptop owner, you are probably familiar with the egg frying heat that can accompany extended use of your laptop. This common issue is caused by poor air circulation beneath a laptop. Or perhaps you can feel the ache of your hands after typing on a level keyboard for hours at a time. There is one remarkably simple invention that can solve both the overheating and ergonomic issues many laptops face. It is the laptop stand.

Laptop stands are exactly what they sound like, a small stand that you can set your laptop on. They are normally angled so that the rear of the laptop is higher than the front, much like the effect you get from the legs on a keyboard. This angling is important because the less you have to extend your wrists to reach the keys, the lower the chance of a repetitive strain injury is. But this is more of a by-product of this invention than the driving force behind it.

The impetus behind laptop stands is the overheating issues that many people face when using their laptops. As a friend once said of his new laptop; "You don't use it on your lap if you want to have kids." He loved the laptop, but the heat generated by its use was incompatible with the basic function of the computer, something portable enough to place in his lap and use.

Most laptop stands are made to be as portable as the devices they serve. They collapse, fold up, and can stow easily inside a laptop's carrying case. One product, designed for Mac users, comes with pads that can be used when the stand is on your lap, and can be taken off when using the stand on a desktop.

If you have a dedicated place for using your laptop, you may want to consider upgrading from a laptop stand to a docking station. Where a stand supports a laptop, a docking station is a little bit more elaborate. They feature attachment points for an external monitor, mouse, and keyboard, as well as Ethernet, phone, and USB ports. The docking stations are a step up in utility, but also in price. Where a stand can be found for $20 or less, you'll be hard pressed to find a good docking station for less than $90.

Or, if you're feeling truly handy, a laptop stand can be made from household materials or other equipment retrofitted for use with your laptop. CD racks, towel holders, door stops, binders, and corks are just a few of the materials that have been used to form a do it yourself stand. These stands are generally less stable than a commercially produced one, but if you are just looking for something to use at your desk, they are an inexpensive option.

Laptop's Temperature Control Tips

By Harun Abdurrazaq

How to keep your laptop's temperature normal steady? The following information will help to keep your laptop's temperature normal and steady.

You need a software which will monitor your laptop's temperature any time without having to check it from BIOS which need to restart your laptop, so that you can decide what you have to do when the temperature is high. I used NHC 2.0 (Notebook Hardware Control) software to monitor my laptop, it is user friendly and free software, and you can control the hardware and system power management of your laptop. Otherwise you can customize your laptop ACPI control system, cool down the system and reduce power consumption, etc. If you have a Dell laptop or problems with the above version please use the other bug fix version.

Tips:

Do not place your laptop on a place which the air circulation is not swift, like on a bed, sofa etc. Because the fan in your laptop gets the air supply from the bottom of laptop, therefore you have to place it on the hard flat surface place, like a table, floor, etc. Exception: you can place it on the bed or sofa or anything else if you only have an external laptop's cooler which usually installed in the bottom of your laptop.

If you found your CPU's temperature more than 60C and keep rising, check your cooler fan, if its rotation keep working, it's mean you have to check the air disposal of it, make sure it's not bold dusty, clean it using small vacuum cleaner or you can open the laptop's case if necessary. After finishing that step, you can turn on your laptop and check the temperature after 10 minutes. If the temperature is still rising to 70C or more then you have to replace your internal cooler fan.

Recycling Dell Laptop Batteries

By James Kara Murat

Recycling is one of the biggest and highly important advocacies of today. It is logical, simple and very easy to do. Numerous environmentalists all over the world are encouraging people to save the planet by not carelessly throwing their batteries away, especially the rechargeable ones, and instead make new things (beautiful and even useful things!) out of them. Recyclable batteries may be found in, among others, cordless power tools, cellular and cordless telephones, video camcorders, digital cameras and remote control toys and yes, in laptop computers as well!

If you own a Dell laptop or notebook computer, you ought to know that you can always recycle your unit’s batteries. Hence, if you think that your batteries have started to act up, don’t throw them right away just yet!

One thing you can do is to contact Dell directly and ask if they can replace your battery for a new one either for free or for a nominal fee. Dell has what they call a “Battery Program” and you might be qualified to avail of a replacement.

Another thing you can do is to drop by a recycling plant or at a drop off center of an organization which aims to collect recyclable items such as your Dell laptop batteries. Compared to the days of old when people had to contact their local sanitation department or go out of their way to go to a recycling center (which, more often than not, did not accommodate individual consumers), there are national organizations now that receive these items and ship them to a recycling or refurbishing facility. Drop off centers are usually the branches of popular supermarket chains, bookstores, computer retail and repair shops, schools and home furnishings stores. If you aren’t sure if there’s a drop off center near your area, search online for some of these national organizations (most of them have websites and toll free numbers) or ask your local government for help. Once the batteries reach the said state-of-the-art refurbishing facility, reusable materials such as nickel, cadmium and iron are taken and used in the manufacture of stainless steel and even in the production of new batteries.

You can do these two things in order to recycle your Dell laptop batteries. Recycling them is not just a way to get rid of what you think are useless batteries. It is, more importantly, your answer to the clarion call of keeping the environment safe, clean and sound for the future generations.
