Some facts are often found on notebook batteries for notebook users Many people think that plugging the charger when using notebook with installed battery condition is good, because there notebook protection circuit that automatically decide when battery power is full. But it was not like that, this is the reason.
1. The main enemy of lithium batteries is overcharge. Although the notebooks now have intelligent circuit that stops charging when the battery is full, but when the battery is reduced again (because he used) will automatically back up to full charge again, and will be repeated. The problem is, in fact after a full he will not immediately end, but still had few seconds until minutes before the circuits actually work to decide the flow of charging. At the time this happens overcharge, if this happens repeatedly assured battery will drop quickly
2. The second enemy is the life cycle of lithium. Lithium batteries have a certain life cycle where each time a charge capacity will be less and less. We charge an automatic circuit breaker working (short-circuit because it is full charge, then automatically refilled when the battery is not full), Charge the battery from 99% to 100% was considered tantamount to fill from 1% to 100% or 20% to 80%, so intelligent charging circuit here instead become a boomerang, because it will reduce the remaining life cycle of the battery.
3. When the battery charged and in use at the same time, the heat released will be greater because there are two conditions of energy processes. Heat generated can hardly seemed to feel depending on the type dekali notebooks, and we know overheating is one of the main enemy of electronic devices. Use notebook with battery and charger installed simultaneously and continuously, confirmed 1 / 2 years the battery capacity you will be able to drop the remaining live 1 / 2 its just the initial capacity. And not until the year your battery can only hold power 5-10 minutes before the notebook out. Indeed lithium batteries. Although not in use, every year its capacity will drop by itself about 25% of initial capacity when he made (normally do this kind), but there are so cara2 durable notebook battery discharged 2 even 4 years old, with a record capacity must be reduced, but still reliable.
How to use the right notebook battery.
1. How to compromise: Charge the battery up to 95% of (not necessarily 100%), use up the battery going down 5-10% depending on the type of notebook, there is a notebook that 15% had wanted to die (the big notebook and thirst for power) is also a 5% still good (netbook). New plug charger while in use anymore. Remember when you want the full (95% of) off charge it again.
2. The way a little trouble: Just like above, only when the notebook will be in charge, notebook standby / power off / not used, fitted’ve lights green / full off the charger. Here intelligent circuit are usually working right, so it does not happen disconnect and recurring charge (because he used) which causes a decrease in battery life.
3. How to repot. Turn off the notebook, sampe charge the green light signal, off the charger, remove the battery and store in a bag. Pake notebooks via UPS’ll be safe. Travel longer fit the new battery installed. This method can not be used for the type of notebook battery built in (example: Macbook unibody).

CNET editors’ review – Backing up your computer shouldn’t be a tedious task. Macrium Reflect Free Edition makes file backup incredibly easy thanks to its intuitive user interface and helpful wizards. Installing the program did confuse us a bit, because although it’s a free program, it refers to purchasing the program, and you’re given a confirmation number. On top of that, the program recommends that you view the online tutorials before getting started, but you might have some trouble deciphering them unless you speak Italian. Luckily, the built-in Help menu is more than adequate and written in English. The user interface is simple but professional in appearance. Intuitive commands line the top of the window, and tabs reveal options for disk images, partitions, XML definitions, and scheduled backups. A helpful wizard guides you through the process of setting up your backup. We were able to quickly select our backup location (local hard disk, network, CD/DVD). Before proceeding, it provides you with a summary of your backup so that you can see the backup type, destination, compression type, and password protection. Here is also where you can make advanced configurations to the compression levels and file sizes. The program did slow our computer while it worked its magic, and we were unable to browse or work with other resource-intensive programs at the same time. However, we were able to watch the backup process, and the program successfully backed up our C Drive without a hitch. If you’re looking for a simple but reliable backup program, we highly recommend Macrium Reflect Free Edition to all users. – Download.com

All Network Administrator will be familiar with server cabinets, the purpose of a server cabinet is to ensure the servers are kept cool, stored in way that it is accessible for installations and maintenance, and help to reduce noise output.
Think of like a bunch of servers all stacked up onto each other, then enclosed in a state of the art server cabinet. These can be seen in many businesses, security offices and computer companies in a separate room or server cupboard. Server cabinets are typically available in a standard 600mm to 800mm width, and 900mm to 1000mm depth. They can also be available with a secure locking system, so the servers will be secure from theft and vandalism.
The cabinets can come in a variety of shapes and sizes, so you are able to fit the desired amount of servers in one cabinet. Co-Location server cabinets allow users to share between each other, further allowing good management of the cabling for maintenance and commissioning. The servers can be accessed through a doorway access from the front or the rear of the cabinet. These can also come open top, sliding side panel, mesh or glass front door and mountable profiles.
Most good quality and strong cabinets can be typically found in large data centres (purposely built for holding masses amount of data onto different servers), in which some cabinets are now able to cool the systems down without having a dire impact on the environment. Traditional cooling methods use a fan, which uses up a lot of energy. Newer methods involve a liquid cooling method as opposed to a fan. Using air conditioning tends to use up more energy in year than any other energy consumption devices.
Using a cabinet liquid cooling device is much more expensive than using air conditioning and fans, however, they are far more effective and beneficial than traditional methods for reducing carbon footprint emissions. Another way of being energy efficient in server rooms and data centres is through good cable management. Stray cables could easily restrict cooling vents and ducts. This reduces energy costs and ensures energy efficiency.
Even though they appear somewhat unessential to certain establishments, they are one of the most important features for many server rooms and centres. They help to keep every server in its place and prevent a disorganised maintenance facility.

Think about the Internet as a highway and your computer is constantly traveling it. Add to that the trips your computer makes when working with applications that are not internet based, and you can rack up some considerable mileage that can result in computer problems if you don’t tune it up a bit every now and again.
In the dawn of the computer age, the proverbial geek took care of the necessary operations to help maintain a computer. Of course back then, by default, only geeks had computers. They were not household items in those days and only those who understood them better than they understood other humans had them. These geeks tweaked and optimized those early computers in an almost secretive manner-only because there was little contact outside of geek and computer relationship.
However, times have changed. Computers are in almost every home, in schools, and in the workplace. There isn’t a large enough geek population to assign a personal one for each computer to come and optimize yours when it needs a tune up. The need for keeping up with maintenance hasn’t evaporated though, and ignoring your computer’s need for optimization can result in noticeably slower running times or a computer that may refuse to work at all.
Since your computer didn’t come with its own personal geek, let’s learn a little about optimizing your electronic friend. First, start with creating a restore point. There is always the chance that something can go wrong and you could accidentally lose more data than you intend to if you don’t have a backup point. Many computers have this application included just in case you forget to do it. Some computers even create restore points periodically so that you have a way to undo whatever mistake you made even if you had no clue that your action would create a problem.
Create a backup of any documents you don’t want to lose on the same precautionary basis as the restore point serves. It never hurts to have a couple of ways to ensure that you can undo what you did if you need it. You can do this by simply burning the documents onto a storage disk such as a CD or a DVD.
Now, run a defragmentation on your computer. This can take a while if you haven’t done one regularly. It should be an option in the optimization options on your computer. Once it is done, take a click over to your antivirus software. Many of these have tools to help you optimize your computer. I know my antivirus program automatically tunes up my computer once per week. It keeps my system running as well as it did right out of the box.
Finally, delete any documents or programs that you don’t need. Just as keeping trash in your apartment takes up space, so do these documents on your computer’s memory. Don’t forget to empty your recycle bin after you’ve finished as nothing is deleted fully and no memory is freed up until that is done. This just opens up more room for your computer to do its thing.
