X121e Close Lid Possible Overheat and Real Time Clock Error

[howardbut]

Hi

My x121e (6 months old) have recenly suffer from possible overheating problem that, when I close the lid, before the system moving into suspend status, within seconds the system sounds two short beep and reboot itself. screen would show "CMOS realtime clock error" and I have to press "Esc" to continue.

By pressing "Esc" I can ignore the error, and I have to enter into Windows to reset the date and clock. A funny issue is that the wireless adapter would be"off" after the reboot, and I have to press FN+F5 to enable the adapter before sync with the internet time server.

It is usually okay if I press the power button to suspend the system first before closing the lid. That's why I think it could be related to temperature although it is not that hot (i think). Can someone suggest a possible clause? The CPU fan works fine and the laptop passed the ThinkVantage CPU/Memory stress test. Core temperature is normally between 44-50C under normal use. Peak temperature (during stress test) was 63C. Room temperature is between 20 - 25C.

BIOS version is 1.14.

Hi

Updated bios and problem presists. I do not think it is due to overheating now, probably RTC or battery issue? 

I will post another message to clarify.
