Real Time Clock (RTC) Mobo remembers power off

[jcooper]

Good morning all
I had to purchase another mobo, ECS KV2 Lite, AGPx8 as the old PC had a
good AGPcard, so wished to keep it, instead of spending more on PCIE + New graphics card.

Installed it all ok (AMD64 3800+ 2.4ghz) 1gbyte mem DDr400. Anyway if I power off for a period of time, then power back on, the clock in windows has the date/time of when it was switched off.

I did the test again for a few hours, but this time, went into the BIOS, and found that the bios clock noted when the system was powered off.

ANy ideas - anyone heard of this issue at all. ????

make sure it has a small battery to power the onboard clock. It may have come "battery not included"

Battery is there ok - I have just got a second one, but normally, if the battery is duff - it defaults to 1984 - this I know, for I have done this a few times. All thisis doing is that if I close/shut down (like last night) on 1 march 2330hrs, when I power up at 0700 this morning, the clock reads 1 march 2007 2330hrs ?? most strange. I am wondering if there is just enough power in the battery to partly keep it not ticking over ??. I will replace later as its processing data at this time for the next hour or so.

Many thanks for your reply.

I have changed the battery, guess what, its fixed the problem, even though the original battery is ok ? Put in original again (thinking its dirty contacts) but reverted back to original problem, so have left the replacement in - amazing, did not think that could happen......issue closed.
