Having problems with your E-Machines eMachines Desktop PC ?

Is there a battery that powers the desk top clock. If so I need to know how to replace it.


Answers :

The battery that powers the desktop clock is a CR2032 for your E-Machines desktop computer. It's a type of watch battery, and is carried in many stores, not just computer related stores.
(About $2)

BEFORE you put your hands inside the computer!

1.Unplug the computer from power.

2.TOUCH the metal frame of the computer case. This will relieve Static.

Your body carries Static electricity. Walking across a carpet floor, your clothes moving on your body as you move, sliding your hand/s across the table, etc., generates Static.

Static electricity, will Fry Out the delicate hardware components inside your computer, in a Flash! You may not see it or feel it!

Computer unplugged you're safe. Touch the metal frame, your computer is safe.

(IF, during replacing the battery you get up, and walk away for any reason, when you return touch the metal frame before you continue.

Work on a table. If you have a carpet floor, do not drag your feet back, and forth. Do Not work on a bed, couch, or Directly on a carpet floor. These are high areas of Static. Do Not use a vacuum cleaner to clean out the inside of your computer. It generates static electricity)

Your E-Machines probably has a TriGem or Asus motherboard.
The placement for the CMOS battery, differs from motherboard to motherboard.

This example from Wikipedia, shows you what the CMOS battery looks like, on a average motherboard,

http://en.wikipedia.org/wiki/Motherboard

On this page go to the photo at the upper right. You can click on it to enlarge it. You can click on it again, to enlarge further.
At the upper Left of the photo you will see a shiny round object.
This is the CMOS battery.

It is to the left of the black Nvidia southbridge chipset, and right below the four black SATA headers. (Connector on a motherboard is a Header)

Click on the photo twice to enlarge it all the way.

See the round black plastic shape around the battery? Looks like a small black plastic cake pan.
To the left, and in the middle, you will see a lock tab.

If you look closely, it looks like two silver lines in the photo. It is a spring loaded lock tab. Once you see yours, and at a different angle, this explanation will become clearer.

The part of the lock tab that physically touches the outside of the battery, is the spring part. You put a fingernail against it, and move the top towards the outside. (In the photo that would be to the Left)

This pulls the lock tab away from the edge of the battery, and releases the battery.

Sometimes the battery pops up a little, and you can get a fingernail underneath it to lift this edge up.
Sometimes it does not.

In this case you need to implement a tool. You can - Carefully use the tip of a metal fingernail file. Wood, however, is preferred.

When you go to reinstall the battery. The Positive ( + ) side goes UP.

After you remove the old CMOS battery, and install the new on, make sure you have not bumped any of your Ram Memory stick/s loose. Make sure the lock tabs are locked against the ram stick/s.
(I don't know if you have one, or if you have more than one ram stick)

Make sure ALL cables are still in tight, to the motherboard, and to the hardware components. (Harddrive, CD/DVD drive/s, USB ports, and so on)

Close the computer case. Plug the computer into power.
WAIT 1 minute, then turn the computer on.
Yes just about all mother boards have a battery to maintain the real time clock. It usually is not hard to replace once you open the case you will see a battery about the size of a nickel. be sure the power is off before you touch anything inside the box.remove the old one and go to Radio Shack or any most any computer store and get the came type (number) of battery. After replacement you will need to reset the clock.\015\012Best of luck!

My HP Pavilion dv9005us has two issues which I cannot resolve. The wireless device is not even recognized or detected by the computer, and there seems to be an electrical problem where the lighted buttons at the top flicker on and off from time to time, which may also be linked to an issue where the computer will at times refuse to turn on after I press the on button and watch it all light up in response and immediately shut off. Any help with this would be greatly appreciated.
