What is CMOS battery?. This is a tiny device at motherboard but able to create a computer system to run smoothly. Following tips will explain how to find out about CMOS battery damage
CMOS battery is a battery that is located on the motherboard body, such as a battery of you general battery watch, but have a wider dimension. You can see CMOS battery problem with the characteristics as follows:
1.When you switched on your computer, you got message 'CMOS checksum error'
The time will remain changing time after time however you have tried to change it to recent time (either in bios or after entry into the system).
2.Computer does not work at all when switched on. Not have any warnings that appear, there is no beep sound at all and the screen does not display any posts anything
You can overcome this problem with the following steps:
Clear the CMOS do the work to restore the bios settings to default conditions (the standard default manufacturer). Can be done with 2 ways namely:
- Disconnect the battery from its place. About ± 5-10 minutes after that, please re-install the battery
- Moving the position of jumpers on the motherboard. To facilitate this operation, you can see on the motherboard guide
Check the CMOS battery holder on the motherboard to avoid the less fit the holder, too loose, and so forth.
If all the steps above does not give you results then you should replace the CMOS battery. When buying a new one you have to know the battery type, because each type has a different number, especially in the serial that is located on the battery itself.

Tips For AMD Based Motherboards
If you use motherboards based on AMD (AMD processor use), this following tips can help you to keep the motherboard live longer, especially if you want to do overclock.
The amount of heat generated by the device-based AMD is still a major trigger the occurrence of various problems.
AMD-based motherboard use AMD processors as well, such as Duron, Athlon and Phenom. For maintenance steps, you can do the following tips:
Use fan / fan casing additional
Hot, yes that is the right reason to use the additional fan casing. Use fan casing will help cooling motherboard and processor too. This also will reduce heat inside casing itself. Usually there are 1 - 3 places at the casing to install the fan, a good casng front or behind. You can get the fan from a computer store.
Motherboard condition
Notice on your motherboard, if the conductor (like capsule form) is starting bloom then ready to change / switch your motherboard, because it's shows the strength of the motherboard is running low. Fast or slow, your motherboard will be 'retiring'.
Alert to overclock
Overclocking is to increase the ability of a device 'excess capacity'. Suppose your processor speed 2.0 GHz, you can overclock it to 2.3 Ghz, 2.5 Ghz, and so forth. In other words, overclocking is a 'force' to device's ability to work above normal.
If you want to overclock (processors for instance), look to the other components, including Motherboards, VGA Card/Graphic Card or Memory/RAM. The action will make overclocking of the other components. You must aware that the temperature in the motherboard already high. Many problems may arise. You must see in the guide first, what should you do if you want to overclock, follow the manufacturer's recommendation.
Monitoring Processor Performance
Processor is the core of the computer device to process the duty of all programs run by the computer. We can monitor the performance of the processor so we know how hard processor doing processing data.
There is a trick so that we can monitor the performance of the processor more easily, even in real-time. The way is as follows:
1. Open the Windows Task Manager button from the Ctrl + Alt + Del (the buttons are pressed together)
2. Click the "Options" menu, then activate checklist on the "Minimize On Use"
3. After that click the "Minimize"
View on the systray (area near the clock, at the right corner the computer (below)), there is the green icon. If we put cursor (arrow) over the icon will appear from the performance of processors that are used with the CPU Usage: 50% for example. This way we can monitor the use of processors in more easily and efficiently.
Cache Technology at Processor
If we look at a specification of the processor will find a term, called a cache. What is Cache? Cache has a function that has a significant role in determining the performance of a computer. When we know what is processor cache, then we will be able to improve the performance of the computer.
Cache can be defined as a space on the processor that functions as a 'place where the data are often used,' the effect the performance of the computer will work faster. The big cache and a faster processor performance because it provides more storage space is large. Average processors now have a large L2 Cache, between 2 - 8 Mb, and even processor Intel Core 2 Extreme QX9650 has a L2 Cache of 12 MB.
Cache in some type, ranging from 1 Cache (L1 Cache), 2 cache (L2 Cache) up to 3 cache (L3 cache). L1 cache is the cache closest to the processor so that it is the fastest way to execute the data.
When we are operating the computer data from hard drives, the data will be moved to memory / RAM, and data from the memory / RAM will also be moved to the cache on the processor. Please note that, if viewed in terms of the speed of access by the processor, the data retrieved from the hard drive is the most slowly, followed by the memory / RAM, and to the L3 cache, L2 cache and L1 cache to the last.
As a comparison, the time needed by the processor to access data from the L2 cache has a speed of 2 - 3 times when compared with the taking of memory / RAM. Because of that, the technology in the processor cache holds a relatively important role in determining the speed of data access.
How To Overcome Overheat Processor
The high temperature of the processor can be a major trigger to be a computer problem. Following tips will explain how to treat the processor in order to have a stable and optimal performance, and also not overheat quick.
Thermal Paste / Thermal Grease
Thermal Paste / Thermal Grease is a material (shaped like a gel) that serves to lift the heat from the processor to the heatsinks. See the function of the existence of Thermal Paste is very important. Make sure the top of the processor you have to be oiled this thermal paste. For information, thermal paste is colored silver / white, but silver has better quality than the white.
Position Casing
Your computer casing must be at the place that has good air circulation. Position of the casing at poor air circulation will trigger the high temperature inside the casing hardware components, especially processors. You can set the computer room where you are
Heatsinks and Fan
Rearrange cable at casing, especially with the type of ATA cable because this type has a relatively large size and width when compared with the SATA cable.
Open the casing cover
If you use a personal computer (not for public use), you can open the casing cover (either the right or left). This is quite effective to reinforce air circulation in the casing. But this can reduce the aesthetic value because the casing will be less than harmonious and its hardware components become visible. But if you place your case under a table or at a corner then you can try it out so it does not reduce the value of aesthetics.
Hope this help to overcome processor overheat .

How To Repair Monitor (Common Tips)
If we have used monitor for several months or several years our monitor get damaged.
An easy way to fix a computer monitor that is to check the flow of electricity to power a series of ration monitor, then to the distribution chain as follows:
[1]. Open a closed back monitor that looks at all the components and equipment affordable by workshop as multimeter, toolset, and other tools. Be careful with the monitor is open, especially at the time of electricity entering the series, because there are extra high voltage of 16,000 volt to 30,000 volt is harmful to the human body.
[2]. Prepare the Multimeter to measure the incoming AC voltage at a series of ration power monitor, normally will be measured, large 220 volt. Continue to measure the voltage on the DC power to remove the portion of DC series monitor on each monitor different brands and types of different magnitude according to the design of each plant. Use the scheme in accordance with the type of monitor being correct, the scheme can get you in the manual full package when buying a monitor.
[3]. Measure the voltage power connectors in the horizontal output transistor, generally equal to 90 Volt DC on normal condition. This voltage show a working conditions of high voltage that can turn the picture tube. When the voltage is down to half, can be sure there is damage to the series of horizontal, replace with a new power transistor. To replace the power transistor is a new type should use the exact same, except if it is not possible then can replace the transistor with others who are similar and higher voltage rating.
[4]. Turn up or down light intensity (brigthness) on the front panel to monitor the position of the maximum. See the reaction on the picture tube, when no change in check around a series of extra high voltage transformer. This needs to be done to check whether the transformer can still generate extra high voltage to set the picture tube.
[5]. Also check the capacitors that connect the high voltage transformer with the ground. Remove this capacitor with a multimeter and measure, if there is leakage change with the new capacitors. Capacitors that are dry will alter the value of capacity and result in changing impedance will affect the extra-high voltage transformer which can not generate voltage as needed, this will be visible on the screen that bleak, dim, or the brightness does not work.
[6]. After all the components that were damaged in the new change, to try to turn on the computer monitor in the new program with the correct diagnosis. Diagnosis Program is run in a special test on the menu display can be made in the guidelines to improve the computer monitor, such as check-It, QAPlus, PC-Technician, JC, Bench, and so forth.
Remember, above tips are just common tips. If you still got errors, the easy ways is bring your monitor to your friend or colleague who knows better about monitor.

How To Choose Harddisk
Most people do not understand the problem of HDD (Hard Disk drive). They only know the size and space, or trademark only, but does not see the other subject.
Therefore, what things are considered in choosing to buy harddisk?
Following tips are things that need to be consider to choose the right harddisk.
1. Size (Size)
To the size of a standard market around 80-120 GB. but I suggest to choose a higher demand because of the larger data.
2. PATA or SATA
I further recommend to select SATA (serial ATA) instead of PATA (Parallel ATA), because of several factors, for example the transfer speed is faster SATA (150MB per second) and use the SATA cable is smaller so that airflow in the PC casing does not interfere.
3. Speed or speed play
Hard Disk (Hard disk) is rotated by a motor with speed. The HDD motor speed is of course also read more quickly. It has a 7200rpm (rotation per minute) and also have a 10,000 rpm.
4. Buffer Memory
The last thing this is also important. Many buyers didn't realize this . Before HDD processing data, HDD always used to go to the Buffer Memory (like RAM) that are on the HDD controller. This is done to prevent a long queue in the HDD. The larger buffer size of the HDD, it will be the better reading or writing data faster.
I hope this tips can help you to choose the right Harddsk Drive.

How To Backup your Data
The data on your hard drive is the most critical items in your computer, and the only item that can not be replaced.You can replace a defective memory module, monitor, or processor, but no data can be replaced when lost.
In addition to the possibility of a failure on the hard drive, the threat of Internet worms, and much viruses have become increasing risk to make your data loss or corrupt. Although you will not be able to provide absolute protection to your hard drive, there are many roads that you can ensure that the data on your hard drive and terbackup protected. Here is two of many methods how to backup your data ...
1. USB Flash Drives
Although I do not recommend that Flash Disk storage is used for the real data, they are a fun tool that will transfer data from computer to the other. Important files can be quickly filled to a tool such as MINIDISK-512-DGRY-CS USB 2.0 Flash Drive, and easily moved to another computer. Installation and operation is very simple. To use a USB Flash Disk just plugin to available USB port on your computer. Approximately on every computer nowadays has a USB port already, with more modern systems supporting USB 2.0 as standard. Speed USB 2.0 data transfer up to 480 MB / s, this is an extraordinary innovation that the speed limit on the USB of the original 12 MB / s, and allows a user to fill them with data drives a relatively short time.
Although the store Flash Disk capacity is increased compared to last year, users are still limited in size-the size of the 512MB until 4GB as I know. A lot of storage is really not an option, but even 512MB can be enough to backup your "My Document" folder, a few albums of MP3s, or files that are important to the other stored in other places.
2. CD and DVD Writers / Re-Writers
Cheap price from a CD-RW and DVD have made them a key material in each of the modern computer. This equipment is generally found on the computer casing, but the tools that support an external USB 2.0 or Firewire more available for greater flexibility and for easy installation.
A combination drive, such as the NU Technology DBW-521, the user will provide a CD reader / writer with a high rate, as well as a DVD readers, for under $ 40. Very cheap from the drive and the blank media to become a tool that can save your data backup, and re-writable media to increase comfort with the leave of the same disk to be deleted and re-used many times. CD writer is generally limited to a capacity of 700MB per disk. It was not enough for a full backup, only enough for archiving files.
Nowadays the prices of DVD writers / re-writers become cheap. DVD media can add users to store far more capacity than a CD, and DVD Burner can generally be able to burn a CD, also the same as DVD. The availability of the latest dual layer DVD Burner, such as the Sony DW-D22A-DO-N, showed a large increase in the capacity of the DVD Write / Rewrite, taking the previous limit of 4.7GB per disc and nearly double it to 8.5GB.
With the right storage, CD / DVD media can provide long-term storage to your data. CD or DVD can easily be read on any computer, making it a good choice for backup your data.
How To Buy Computer
In the midst of such rapid progress in the sector of information and communication technology, the computer is not a part of the body separated from the era of progress and community life. It makes more and more people are familiar with this thing called a computer. Various activities can be done more easily thanks to the help of computers. From simple jobs such as typing a letter, to edit a photo or send a letter via e-mail, can be performed by the computer. Even now the computer has been used as a medium of entertainment such as listening to music, play games, to watching TV and, of course, making Blog (Web Log).
Can not be denied that all the convenience offered by the computer to make so many people want to have it, although there are people who want to have them only because they do not want to say lag period. However, funds become problem nowadays, especially when prices rebound as being at this time.
We may not pressing the price is lower, but we can make trick to purchase of a computer in accordance with our needs. Well, if you want to buy a computer while the limited funds, here are some tips:
Office Class
Computer is used only to type only (Office Class) certainly does not need a computer with high specifications and expensive. Enough if the computer is able to run office applications (eg, word processing and spreadsheet). But the funds would be divided to spend some significant enhancements, such as: printer, scanner, fax-modem, and the media player while disc author. Look for a printer with good quality, this is to print the results of the paper better. Basically this class perform activities: typing, copy, print and send, so the device associated with the fourth of these activities must be good.
Gaming Class
Computer used to run the game application (Gaming Class) requires specification of the device / component that is very good, especially for a device: display (monitor) the broad, graphics (Graphics Card) is sufficient to run the graphics rendering 3D gaming with enough memory capacity, and memory (Memory Module) computer that big and fast. Graphics card and memory module holds a very important role for this class, find the quality is very good and support the game for next-generation game. Besides, the play activity is usually done in a long time, it needs the card fan and better cooler for the processor. And do not forget some special equipment with gaming, such as the joystick, joypad, or streering wheel.
Multimedia Class
Computer Multimedia (Multimedia Class) more on the activities related to: good sound and visual play, edit, and print. Purchase the device that is associated with both, especially: sound card (Sound Card) good quality, display (Monitor), which is big enough, players and writers disc (CDRW or DVDRW), speaker, headset, multimedia keyboard, TV tuner, scanner and don’t forget webcam, especially if you like chatting wiyh others.
Professional Class
There are also groups of users who want a computer with special specifications that are usually directly in contact with professional (Professional Class). This is a group of computer users with needs special hardware and software specifications for one or two jobs, for example, the graphic design and video editor. Specification of the device / computer components are very diverse and highly specialized depending on the job, the needs of high technology that is used, the level of expertise, and media work. Usually the price for this group become the number two, and technology development (both in the field of technology development work and the adjustment request) to be number one. Tips for this group is the use of funds according to technology absorption, do not buy the device / component high-tech but can not use. Adjust limit the ability to control, run, and produced the paper with the technology used.
Collect and review the news from a variety of devices / components will be purchased, or the responses and effects when other people use.
Everything can be searched from magazines (both print and online, such as Chip, PC World, PC Magazine, PC Computers, PC Guide, PC Plus, etc.) or sites such as AnandTech reviewer, Tom Hardware, HardOCP, and others - other. Do not just rely on one source only, moreover it is a magazine or a site sponsored by a specific manufacturer brand. Usually any posts or reports of many more people can be trusted, because of differences in time between the device / component is tested in the laboratory with that used by most people. Test results conducted by the magazine or website is usually generated from the device / component manufacturer selection, not the objects circulating in the market. So do not wonder if any magazine or site recommend a device that they are very good, but the market turns the device is less good. Another source of information where we find a good while to ask is on the site forum.
Ask and compare it to many shops / distributor device / component.
The more we ask, the more we freely choose. Buy a computer can be high risk if we only come to ask just one store to buy a ago. Ask your friend or your relatives is good to make better decision.
With friends or relatives who have enough knowledge about the device / computer components we will feel safe and comfortable. Ask as much as possible a knowledge. Try to give freedom to him to give opinions.
Watch what can be offered by a store retailer.
In addition to the device / component itself, there are some important things that need to know when we buy a computer : After Sales Service (system warranty, the type of service offered, whether the store can accept Trade-In, and others), service location, phone number , the availability of backup devices (stock). Try to do the test on the device / component that will be purchased in a store retailer. Also compare price list that you can with computer online sites.
I hope this can help you to make better decision buy a computer.
