Everyone who is has ever owned A4000
should know how bad damage old battery at location BT176 will do to PCB

battery "Date created" file attribute will always go wrong, because the
motheboard has no calendar and clock that could survive power off. To
be able to use real calendar and clock again the best thing is to have

Only 2 holes of 4 are needed for CR2032 battery and battery holder.
Be careful not to damage PCB surface or nearby resistors while
desoldering the old holes and soldering the battery holder.
