BIOS chip or MB (A7N8X Deluxe)

Thats all i was commenting on, it wouldnt cost you much to try. Check out Paul's response. He's got class and it has nothing to do with his knowledge, but rather his attitude.

Thanks, But I don't think so. In my 16 years of building IBM clones, I've never seen a MB whose BIOS wouldn't save data just because the "Battery backup" was dead; which is all that battery does.

Joe That would depend on whether there was damage to the dual ORing diode feeding 3V to the Southbridge. If the path from +5VSB/3VSB is burned out, you'd be dependent on the battery. The diode is sometimes damaged by using the "clear CMOS" jumper and leaving the power on the computer running. As an example, download this document and look at page 18. If diode D2 is burned, then you're dependent on the CMOS battery and D3, to save settings. Many motherboards in the past, would short node JP17 to ground, as a way to "clear CMOS", as an example of a way that diode D2 can be burned if the computer power is left on. On modern computers, both of those diodes are housed in a three pin package that looks like a SMT transistor. The burned dual diode can be burned bad enough, that you can't read the part number off of it, to order a replacement. http://www.intel.com/design/chipsets...x/BXDPDG10.htm There was a serious bug with those motherboards, in that saving settings could result in the motherboard never posting again. http://www.nforcershq.com/forum/image-vp32049.html But your symptoms don't match that bug, as you're able to recover. My theory is far-fetched, and I don't have any other suggestions as to why settings could not be saved in the CMOS 256 byte RAM block. You'd think, in any case, the motherboard would compute the checksum on the CMOS block (no matter what state it is in), and figure out it was corrupted, and return everything to default settings again. It shouldn't really black screen, unless the checksum is correct by accident, and the BIOS "eats" the bad settings. If you have a magnifying glass, the dual diode typically has a marking of "K45" on top, and should be located in the neighborhood of the battery.

I really appreciate the length at which you'll go to help someone. And unlike some people, you address the problem and not the symptoms. Very professional in deed (indeed)!

I hope I can someday repay you, or maybe it will just be enough to pay it forward. ;-) Have a good one! If you do try a new battery, will you at least tell us if it helped? |

It wasnt a rushed comment on my part, it was just a try the cheapest route to see if it helps. The age of your MB screams the fact that you at least need a new battery anywys. Thats all i was commenting on, it wouldnt cost you much to try. Sorry that you misunderstood my brief description of your original efforts. What I meant was that I know for a fact that it's not supposed to work that way because of my long lived experience and while it could be that there was something unusual with this particular board, I've already changed the battery once before and the indications I've outlined are not consistent with the previous symptoms. So I know that your solution is incorrect with respect to "PROPER" operation. I'm not one of those backyard mechanics that holds things together with bailing wire and bubble gum. My longest lived job was in aviation and you never take shortcuts. I find the EXACT cause and do the EXACT fix required. Nothing else is acceptable! As Paul mentioned, if a diode is fried, a diode I'll replace. It won't be a problem because I also worked as an Electronics tech for a short period of time (not on MB's) on Audio equipment. But a diode is a diode no matter what the package. And my soldering skills are more than adequate. So in my mind "rushed" is indicative of not considering a diode. Also the flow of the message seems somewhat rushed, not well thought out. Nothing personal just my take, my opinion. Check out Paul's response. He's got class and it has nothing to do with his knowledge, but rather his attitude. He seems to really want to help someone, A TRUE Gentleman and Scholar. You sound like a washed up loser, get a grip. Thanks for nothing! What? Are you new to USENET? that comment, in fact this entire message was for Steve. Thats how thread hierarchy works. The persons message a particular message is attached to is a response to that particular person and no others. As I previously said, THANKS for your EFFORT! I'm always extremely appreciative of those that are altruistic in their response. But anyone thats more concerned with jerking their own chain can go jerk it elsewhere. |

So as well as a fiction writer do you also talk to yourself? Seriously dude, I don't know what in the **** you're talking about. I'm the original owner, no ones touched the MB but me, and it's never been mishandled. As to assume that their is only one way a circuit can die. Dude let me educate you, on average Caps are usually the first thing to die in any circuit from just plain old age, from doing what the were intended to do. You guys are ****ing newbies, backyard computer fixers. I bet you call SIMM's and DIMM's "memory sticks." You can take the ****ing BACKUP BATTERY out and throw it in the trash (well actually all lithium batteries should be recycled) and the BIOS and the motherboard will work FINE, just don't unplug the PS from an AC source of you'll find yourself resetting all the BIOS settings. ITS A ****ING BATTERY BACKUP FOR YOUR BIOS SETTINGS AND THE RTC for god sake. It only comes into play if you loose power. Now like Paul has outlined if in fact the circuitry supporting the sensing/switching of power sources fails then the problem is the circuitry, the possibility that a dead battery can cause such an indication is only a SYMPTOM of the REAL problem. Some people are just clueless. |
