a buddy of mine has a clevo nh55dc. Every time he turns on the computer, if the computer have been unplugged from the AC adapter (even with the battery in) a bios message comes up. "A first boot or nvram reset condition..." and an OK button. Before the message the machine seems to reboots itself, like it is reloading the settings. If he never disconnects the AC adapter the message never shows up.
We have replaced the CMOS battery with a new one, thinking that this would be the problem, but it did not solve it.
Interesting is that when we replaced the CMOS battery the date as expected was reset to 2019/01/01, but when the problem happens the date is not reset to 2019, it only seems that it loses some minutes, like if the clock stopped.
We installed three different versions of BIOS just to see if that would happen, but nothing changed.
Can't figure out what might be going on, what else can cause such behaviour if not the CMOS battery?
