How To Change Your Motherboard Battery

First the safety rules!

The inside of a computer is a bad place full of electricity and sharp edges.
On the electricity side always when working on you computer make sure that it’s still plugged in to the power socket and the power is turned off, this is to ensure that any static
From you is discharged through the earth. The inside of most computer cases are unfinished metal and has very sharp edges so be careful.

The first signs of a battery failing are:

Your clock starts running slowly
When you boot (start) your computer it has a problem finding your hardware (no hard drive, no cd rom)

To change the battery you need the following tools:

a X-point screwdriver
an anti-static strap(optional)
a new battery (seems logical)

Then unplug all the cables from the back of the computer as you remove them make a note where they came from. (So when you finished you can put them back).read more



Move the computer somewhere where you can work on it with ease
Remove the cover by locating the screws around the outer edge (back) of the computer
Some computer cases only require you to remove 2 screws on one side then a panel can be removed allowing you access to the computers insides, others you must remove 6 screws and remove the whole case by sliding it to the rear and lifting it off.


Now make sure that you read the safety instructions about static.
Look inside you will see a round silver thing that looks about the size of a 10p piece (quarter). This is the battery itself, carefully lift the retaining clip and slide the battery out. That’s it removed now go to your local computer retailer, electrical retailer (Tandy/Radio shack) taking the old battery with you and get a new battery.
Back to your computer insert the new battery by lifting the clip and sliding the battery in.

Reinstall your case and plug all the cables back (you did remember to label them didn’t you)
Turn on your PC. You will now need to go into you bios….
Right the bios is the god of your computer. To access it, when your computer first starts you will see a black screen with white text.
If you look carefully you will see a line that says something like "press del for setup" or some other key (F2 or ESC or tab) this will take you to god's house where you can make lots of changes to the way your machine works.


It is also the place where you can make your nice computer in to a rather expensive door stop so be careful and don’t go playing with anything.
You will now be presented with a blue screen with a lot of options on it, the one we want is Load Optimised / Default settings.
Press the F10 key for save setting and type Y, the computer should now reboot.
If every thing went well then your computer will now be up and running.

Extreme way (NOT RECOMMENDED):

Keep computer running.
Lay it on it's side and remove side cover to expose Motherboard.
Take any thin object, "small screwdriver, knife point, wood shiskabob skewer.
Pull back the battery retaining clip.
Toss the old battery in the junk receptacle, unless you belong to Greenpeace and want to save the earth.
Install the new battery. No need to reset bios becasue the compter supplies voltage to the CMOS while it is running.
Reset or resync clock with internet. Done!

Choice LCD Wall Mounts: Fixed or Variable type?

lat screen LCD's have the perfect shape for putting it up on the wall, this preserves space and can be viewed as a peice of art when above the mantle or with other pieces of art. The mounts for LCDs have several types that will be discussed in this article. They can be either fixed or variable, of course as the name implies the fixed mount doesn't move. A fixed mount is a very sleek look since the television is only an inch from the wall, but this is best used where the seating in the viewing room is a fixed place.read more




The variable type wall mount is best is someone wants to be able to adjust the television. For just slight movement a tilt wall mount will work, it will permit some movement perfect for a case where there is a light glare issue, or if there are children watching, it can be tilted toward the floor. This tilt wall mount can be hand adjusted or with a tool, this one will cost a little more than the fixed mount.





For full motion you may want to look into a type of variable wall mount that has arms, which allow you to move the television up and down, back and forth along with left and right. Amazingly a number of these types of mounts come with a remote control that allows the television to be moved from where you sit, a huge convenience. In addition, there are ceiling mounts which offer a unique look, in case there's not a way to mount it on the wall.

There are pros and cons for every wall mount available. A fixed mount will not have adjustability but it will carry a greater weight. The further the TV gets from the wall the less steady it becomes, as even the smaller LCDs are around fifty pounds. A heavier, bigger television will have to have a much sturdier wall mount, and this will drive up the cost, especially if it's adjustable.

Research and shop carefully for your wall mount as they are not all the same, it must be appropriate for the size and weight of your LCD. There are matching wall mounts available from the manufacturers but these often cost more than those built by a third party company. Investigate all aspects of the wall mount including looking at the room where it's going to be mounted to make sure it's the right one. If you make a good decision about what type and where to put it, then your viewing experience is going to be enhanced.
