ASUS G73JH system clock going wild oO?

I have a quite funny issue since I reset my BIOS manually by removing the battery temporary. More informations about that can be found in http://forum.notebookreview.com/asu...-help-bd-prochot-bios-mod-bricked-my-g73.html

I even measured the strength of the system battery before I put it back and it was giving solid 3,0V~ as it should.

But in the last few days my system time / date is setting itself sometimes to random values, e.g a few days ago it set itself to the 25.07.12, then to the 01.01.2013 and today to the 20.01.2011 oO

Any idea what could cause this issue?

 

How is your System Time and Date set in the BIOS? Is it correct for your local time and date?

Does it change only on a restart of the laptop?

 

It changes also the time in the BIOS and I guess thats the cause.

Yes, it changes only when I turn off the notebook ... a simple restart won't change it. Still it does that not always, just every 2-3 days~

 

So I guess nobody has an idea why my clock module is on drugs?

 

It's possible something at the OS level is corrupting the real time clock.
Any chance you are running NTP, or any apps, that monitor the
CMOS state? To see if it's Windows related, you can try booting a Linux
LiveCD, and see if the problem occurs. On the hardware side, you could
have oxidation build-up on the battery contacts. Try cleaning them with
alcohol and/or a pencil erasure (battery also). You might have a marginal
battery, that gets weak under load, or a capacitor/diode/transistor/chip
going bad, in the RTC circuit. If the problem never happens, while the
laptop is running, then it is likely something going wrong with the
backup power, when the unit is unplugged (Lithium battery and/or
associated circuitry). When the unit is plugged in, but not on, the main
power brick should be providing standby power, to the RTC circuit. You
might want to try each power state, and see if there is a correlation to
the problem:

1. Leave running for a few days
2. Leave off, but plugged in
3. Leave off, and unplugged
4. Combinations of above, with main battery in/out of system

Good luck,

Thank you for the answer.

It sadly goes still "wild" ... the time is mostly kept but the date is being set an few days into the future. When I correct the time and restart the notebook it works just fine, only on the first start each day its setting the date an few days into the future, mostly with the correct time though.

 

You could try getting a new CMOS battery.

 

I tried that already, new battery which is also filled just fine. It seems to be nothing "random" due to an power loss or something, its a kind of "system" behind which adds always 2 or 4 days

Maybe the notebook is trying to tell me something? Maybe its alive and can see what happens in the future ?

Joking, but this issue is seriously quite annoying. I thought already to use an modified GRUB loader to see which date and time is set before its loading any OS.

 

Hey Guys,
I am having the same issue with my G73JH,
It's very annoying and i don't know what to do,
decided to send the laptop to the Asus Service center but apparently they did not found anything wrong with the laptop,
i know that this thread is since 2012 but i was wondering if anyone found a solution for this problem,
it would be dearly appreciated...
Thanks in advance!

 

Nope, the issue still appears for me ... sometimes daily ... sometimes not for weeks.

 

It could actually be an error with the timing circuit itself.

 

Well I kinda got used to it, now the screen died though, hope its just the cable -.-
