Power Outage Related ?

[John Naylor]

Have a water cooled system Win 7 Pro system,overclocked the begeezes out of it back in 2013. For safety reasons, transitioning to a new system; but keeping it around for several reasons:

• It runs everything I need to run and is more comfortable than the new laptop
• I still play games and enjoy the 600 watt sound system
• It's a SOHO server (though have additional backups.
• Just to see how long it lasts

This morning (before dawn) I woke up to a power outage, figured I'd wait till the UPS started beeping to see if it came back on. I later woke up to the fast beeping knowing I only had a short time to shut down. Was well into the shut down process, ... but did it finish before the UPS battery did ?

Power came back on a few hours later and I booted to the BIOS message saying clock is wrong and therefore could not go online. Just bypassed it and went in thinking it would reset itself once logged in. It didn't. Also got messages saying puter wasn't going to connect to internet because of safety concerns. So I uninstalled my Kaspersky that has just recently expired and I hadn't gotten to yet, and made sure Defender was on the job. Still no go... presume the time thing.

So assuming that the CMOS battery was dead, I was dismayed given that in order to replace it, I had to drain the system and remove the 2nd water block ... I wish. After looking, I was reminded that the MoBo is covered by a shield and which included a Chipset block. When originally building this box, replacing it was not in my mindset as I never thought this PC would still be viable 13 years later.

The system is still keeping time .... whether that survives a reboot, I'm not sure. Anyone have any insight as to what happened here ? I think'd I'd abandon the system rather than disassemble and reassemble everything.

sounds pretty much like a dead cmos battery. certificates, websites and a lot of stuff refuses to work when the time and date is significantly off.
CR2032 batteries are lasting a long time but not over a decade. a good and brand new one lasts (at least after my experience) between 4-6 years on average.

I reboot like once a month, so not exactly terrified if all I have to do is reset the date each time

and losing your bios settings after each power cycle.

All I had to do last time was change the time.

Restarted and all was fine ... shut down, made a sammie for dinner, came back and cold booted,all was fine. Going to have to dig down and see if any settings were changed .... assuming at this point things are OK until I have a chance to so a deep dive and check settings

Replace your motherboard's coin cell battery at your earliest convenience, you can get a high quality Duracell or Panasonic CR2032 at any drugstore, it's the same as many medical devices such as Accu-Chek blood sugar monitors use, it shouldn't cost more than a couple of bucks and it lasts a decade plus when used as a CMOS battery.

I have a a 12-pack of batteries, one was used, 11 left.

As indicated in the OP, replacing the battery would involve:

Draining the cooling system
Removing all "hard"rigid pipping and fittings, flowmeters, reservoir, etc
Removing the MoBo "Shield" and integrated chipset water block.

Of course after doing and system being disassembled, all that would dictate flushing out all the components, remounting 4 water blocks and reapplying TIM..... and hoping that the rubber seals in all the fittings weren't damaged on disassembly and cable swapping goes well. That's at least a 3 day weekend. It took 3 weeks to build.

Other factors:

1. The timing seems off .... the power outage and batter dying at the exact same moment seems too coincidental.
2. Several reboots and shutdowns later, it's still performing fine.
3. I just bought a new laptop as a replacement for this 13 year old box. In the midst of moving everything over. Hard to justify the T & E.

Put it on a shelf or try to get whatever value you assess it is worth in a quick sale.

Commenting to note duplicate of exact system response you had was exactly where I arrived at, CMOS battery after power blip. Spare replacement battery that had been laying around was very temporary fix. Brand new one immediately made clear full response was restored and would be maintained for sufficient number of stable years to be a bit odd again.

So, changing the CMOS battery is accompanied by 3 days of work?

Think I'll stick to air cooled.
