Frozen Time Clock in UEFI - The Fix

[Raja]

Is your motherboard suffering from the malady of a frozen time clock in UEFI?

If so try the following:

1) Reflash the latest UEFI, using EZ Flash 2 or USB BIOS flashback.

2) When the system POSTs, enter UEFI. Once in UEFI power down the motherboard. Keep the PSU attached and "on". Only the motherboard is powered off and in "standby". You will see the MB standby lights on (boards with start buttons onboard will be lit). Standby does not mean the board is actually running, standby means the board has power, but you have not pressed the power button to turn it on. Make sure the board is off before you go to the next step in this list. You will know if it is off because if you leave it for 5 seconds it should not POST~BOOT - this means it is in standby.



3) Clear CMOS (Clear RTC) for 10 seconds. This will clear the Management Engine.

4) Power up the system, enter UEFI, set the clock and then save and exit.

5) Update MEI driver to Version 9.5.14.1724 in the OS.









6 )Carry on using the system as normal.

The above steps should fix the issue.

CiscoX,

I reset the clock yesterday and when I turned the PC on today it was still the right time and has kept time fine all day.

Seems like 1505 doesn't solve the problem completely but helps some.

I've had the hour jump back happen with the 1505 bios too. But the clock doesn't seem to get stuck anymore, so I guess that's some progress.

I just got off the phone with a very helpful gentleman at Asus:

1) As far as he is aware, the only "Fix" is the one on the 1st page of this thread.

2) He has no information indicating a new BIOS that "Cures the RTC Stop Error" is a fix for anything.

3) He was surprised that the Clear CMOS procedure described herein is to be done with power connected; he has always been instructed that this should be done with power off. I have done it both ways....1st as Raja instructed and after with off.

I am being e-mailed paperwork to fill out while he researches the issue further.

FWIW
According to Raja, with the power off the CMOS is cleared but not the IME data, with the power on, the IME data is cleared.

Yes, what I found surprising is that TS doesn't know that. I explained that to him, read it to him off the 1st post and he was still incredulous as to why that would be of any benefit.

It's been two weeks since I talked to tech support. No communication from them at all.

Just another update. After the 1505 flashed bios update and Cmos reset it's now been over three weeks and all is still holding well. Fingers crossed!

My windows clock was way out of sync again after 1505 update...

I used the jumper to clear RTC (as per usual) and this time it completely goosed my motherboard. The power switch on the case done nothing... I checked the connection and it was fine. I tried the (lit up) start button on the mobo and nothing. I thought it was a goner. Didn't beep, no fans came alive, no Q-CODE... It done nothing except sit with its Start/Reset lights lit.

I don't know what ended up fixing it but in my furious state I unplugged from mains, unplugged CMOS battery, cleared the RTC again and waited about 30 minutes. After a cup of tea and calming down I plugged it all back in and somehow it came to life..

Bear in mind I have cleared the RTC hundereds of times already and had no issue like this one... This only appeared after 1505. The clock is still running OK at the moment but it -will- go again and I hope I don't get a fright like I did last time with dead mobo.

ASUS... Get your act together... Releasing **** and losing your customers is not building your business...

Question - how exactly did you do this?

i.e. Did you update your bios using the windows EZ Update program? OR The ASUS EZ Flash 2 BIOS utility? OR The ASUS BIOS Update program?

After this - how did you reset the CMOS?

[jesus_glorious]

Sorry for the late reply. I used the bios update option utilizing a flash drive plugged directly into the rear flash port. Instructions are in the MOBO manual. For the Cmos reset I used the reset button with system off first, then just for general purposes, did it once again with system on. Been just over a month now and still holding.

Used manual flash utility from rear flash port. Used Cmos reset button...twice. once powered off..once powered on. Over a month and still holding.
