Are you always running out of battery power just before you take that perfect picture with your digital camera? Here are some tips to conserve your batteries when you are out “snapping away”.

1) Turn off your digital camera when not in use. If you are in a situation where you must snap pictures quickly, this may not apply as turning digital cameras on and off take a few seconds, and may cause you to miss a picture-taking opportunity. However, if you are taking a leisurely stroll and can afford a couple of seconds before snapping a still subject, by all means, conserve your digital camera’s energy!

2) Many digital cameras have a regular viewfinder and an LCD viewfinder. While the digital LCD viewfinder has its benefits, it can drain battery power. Turn it off when applicable and use your regular viewfinder for taking pictures.

3) Don’t stop after taking every photo and look at the picture in your digital camera’s playback mode. Granted, you sometimes need to look at photos immediately after shooting them in order to make sure your exposure is correct, the lighting is ok, etc., but doing this does use up your digital camera’s battery power.

4) If you are using MicroDrive media, be forewarned that these miniature hard drives may take up quite more power than Compact Flash cards.

Taking care of you new battery pack

Normally, a new battery pack comes in a very low charge condition and must be fully charged before use. Refer to the user manual of your portable electronic equipment for charging instructions. A new battery pack needs to be fully charged and fully discharged or “cycled” as much as five times to condition them into performing at full capacity. Your equipment may report a fully charge condition in as short as 10 to 15 minutes when the new battery pack is being charged for the first time. This is a normal phenomenon especially for Nickel Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) chemistries. When this happens, remove the battery pack and let it cool down for about fifteen minutes then repeat the charging procedure. “Conditioning” (fully discharging and then fully charging) is necessary so as to maintain the optimum performance of a battery pack, and is recommended at least once a month particularly for Ni-Cd and Ni-MH batteries. Failure to do so could result in reduced charge capacity and can significantly shorten the battery packs useful life. Lithium Ion batteries do not require conditioning. It is normal for a battery pack to get warm when charging and during use. However, if the battery pack gets excessive hot, here may be a problem with the portable electronic equipments charging circuit and should therefore be checked by a qualified technician.

Rechargeable batteries undergo self-discharging when left unused for long periods of time. This is normal particularly in the case of Ni-MH and Li-ion chemistries. For best results, always store a battery pack fully charged. It should be removed from the equipment and kept in a cool, dry and clean place. The amount of runtime a battery pack produces depends on the power requirements of components in your electronic equipment.

Don’t let under-charged batteries keep you from taking great photos. If you infrequently use your digital camera, you may think that you after you use your digital camera, recharge your NiMH batteries, wait a few weeks or months, then use your digital camera again, that your batteries will be charged and you’ll be ready to snap photos, right?

Oops… Do that and you’ll be stuck with a non-functioning digital camera or one that just blinks a picture showing a dead battery. Rechargeable batteries don’t stay charged forever. They tend to lose a little bit of their power every day. If you charge your batteries and frequently use your digital camera, you will probably never notice this loss of power. However, after a couple of weeks, the power loss may be noticeable, and after a couple of months or longer of non-use, those once ready-to-go batteries may have lost enough power to make them unusable.

Don’t get caught in this trap. Always charge your batteries before every trip, and make sure to use a battery charger with a sensor that prevents over-charge.

Decide which type of CPU to use

This may seem irrelevant to choosing a motherboard. In actual fact, this is the most important thing you need to do before selecting a motherboard. The reason being that the type of CPU will determine the type of motherboard you need. For example, if you choose an Intel CPU, then you have to get the socket 775 motherboard or else the CPU won’t fit into the motherboard. Deciding on the type of CPU will help you to make a better choice when choosing the best gaming motherboard.

Determine if the motherboard supports the type of CPU you have chosen

As mentioned before, if you are using an Intel CPU, you have to get a socket 775 motherboard whereas an AMD CPU requires a socket AM2 motherboard. In addition, some of the older socket 775 motherboards do not support dual core processors (even though they use the same socket) or even quad-core processors. Check out the manufacturer’s website to get confirmation before you buy the motherboard.

Overclocking feature

If you are overclocking your CPU, you have to get a motherboard that allows you to change the FSB speed and CPU voltage in small increments.

RAM support and no of memory slot

Your motherboard must be able to support DDR2 RAM, for a simple reason that DDR2 is currently the fastest RAM in the market. Extra thing to take note is the maximum speed of RAM that the motherboard supports. Some motherboards can support only up to DDR2 667MHz RAM while the latest ones can support up to DDR2 1066MHz.

In addition, you may want to upgrade your RAM in the future, therefore your current motherboard must have at least 4 memory slots and can support up to 8GB RAM so that you have the option to upgrade in the future.

SLI/ Crossfire ready

SLI / Crossfire ready motherboard means that you can make use of two identical high performing graphics card to render the graphics, thus achieving a faster and more realistic video effects. Not every motherboard supports this feature. As video effects getting more and more advanced, it will be soon that SLI or Crossfire technology becomes the standard for video display. Therefore, even if you are not using this technology now, it is still advisable to get a gaming motherboard with SLI or Crossfire feature.

SATA 2 controller

SATA2 can transfer data at twice the speed of SATA 1. When it comes to gaming, every single speed counts and that increase in speed might be the deciding factor in your game. A SATA 2 port is backward compatible with SATA 1 devices, but not the other way round. It is better for you to get a motherboard that supports SATA 2 devices. In addition, if you are using RAID, then you have to get a motherboard that has four SATA 2 ports.

Extra Features

You might want to consider extra features such as extra USB2.0 ports, firewire, integrated LAN and front-panel LED when choosing a gaming motherboard. Some of the motherboards contain more features than the other and you have to compare around to see the differences.

Features such as integrated sound and video are not as important in the best gaming motherboard since they could not contribute well to a good gaming session. For a gaming computer, you have to get a separate graphics card and sound card so as to play the latest game in the market.

Conclusion

When getting the best gaming motherboard, it is worthwhile to do some market research and compare with various boards. Since it is the most important part in the whole computer system, don’t ever scrimp money on it.
