The battery. Make sure you have a good hold on it before removing & replacing. If you drop it on an a energized circuit you can short something out.

I pay about half that, for a slow DSL connection. to nz.pool.ntp.org I get ICMP pings between 34.7 and 35.8 ms (6 hops). and TCP pings in the same ballpark. OTOH to the national standard I get 5ms jitter I haven't bothered to optimise my NTP settings I'm still using the defaults. which is pick 4 servers at random from an international pool. -- &#9858;&#9859; 100% natural

I'll check my manuals, but it is more difficult to make static ram that needs battery than a bit of flash. Look at the common PICs, AVRs, and such; very many have flash, none have static ram requiring battery. ?-) =20

The way to really get the point across to the is to force them to use = only the green products that are seriously inferior. ?-)

It has a line cord and brick for doing the SPICE runs. Other than that i seem to get over 5 hours no problem. ?-)

Some did. Some were on the clone motherboard, some pluged in under the BIOS Eprom and some were on a card. The cards were good sellers.

Yes, but sometimes you have no choice. The dying battery has scrambled the contents, and the default gets you close. The one that got me the first time was the motherboard booting too fast for an older hard drive, and having to turn the memory test on in the BIOS to slow it down. That was early Pentium boards, if my memory is correct.

Your Internet connection has latencies and jitter as well. see what the FCC says about your hooks. See who they say the best is. http://www.broadband.gov/qualitytest/ookla.htm I get 24 down and send 20 up, and have 36ms latency with 2ms jitter. Damn near T3. Not bad for $50 a month.

Last week I was able to reset the CMOS on a modern (2012) board by shorting the battery contacts. I can't say for sure that Foxconn wasn't emulating CMOS by detecting the short or the loss of clock power. but It sure behaved like it was actual CMOS. I had configured the bord in such a way that the onbord display hardware was inactive and I needed to get it back, a brief visual search of the board didn't reveal a CMOS reset jumper. -- &#9858;&#9859; 100% natural
