Thank You Roger in UK. It could be one of the many versions of K7S5A. The ECS site doesn't behave very well. I've had trouble with it, and some of the trouble seems to be browser specific. In any case, if you're lucky, maybe the site will respond for you. You should be able to get a manual for your specific motherboard. http://www.ecs.com.tw/ECSWebSite/ECS...&keyword=K7S5A This would be an example of the manual. It must be unzipped to get to the PDF inside. Well, unfortunately, the battery is not mentioned in any tangible way. So we'll have to find a picture... http://download.ecsusa.com/dlfileecs...k7s5a31eng.zip ******* Here is a picture of the board, which happens to show the legend on top of the battery. http://www.808.dk/pics/k7s5a_tempsensor2.jpg I see the standard type CR2032 printed near the bottom of the info on the top of the battery. A CR2032 should be available virtually anywhere (like RadioShack). I think all the motherboards I have here (spanning ten years of motherboards), use that same battery. ******* You can see in the article here, the CR series are named according to their dimensions. 20mm diameter, 3.2mm thickness. If you got the wrong one, it would not fit the socket properly. Rather like trying on shoes... See "Lithium coin/button cells" http://en.wikipedia.org/wiki/CR2032 I suppose there could be some temptation to stack two CR2016 cells on top of one another into that socket. Don't do that!!! (Too many volts.) The circuit expects a roughly 3V source. Once the battery delivers 2.3V or less, it is time to change it. (2.0V minimum for the Southbridge, 0.3V for the one way diode in the circuit path.) Those batteries are not supposed to be charged, which is why there is a diode in the path to prevent accidental charging. If charged, the battery would burst. Lifetime is 3 to 10 years, depending on usage pattern (switching off the PSU at the back, shortens the life). HTH, Paul |
